I have an rca d52w19 52 in...recently my wife tried to move it while dusting when the tv was on and she broke off the coax insert in the back.. women cant live with them cant live with out them...anyways now it has no power led in the front blinks 3 times and thats it ..it also clicks when the led flashes at the same time ...sounds like the clicking is coming from the fly back..i checked the glass fuse on the power supply board its good i checked the 3 small fuses besind the fly back they have continunity ...is there more fuses on the power supply besinds that one where the power cord gos in...can breaking off the coax insert blow the flyback .....can it be the tuner shot and where is that on the main board ..i dont want to start taking things apart untill i know where to start ,,,what can it be ..the tv is 5 years old not very many hours on it pic was excellant ..be ashame to scrape it ..can u help me out .peter
The problem is not with the mail filter board as that only supplies standby voltages to the chassis. If the led is blinking 3 times the most likely scenario is the flyback , Thats why the clicking from flyback coincides with the led's blink. If you look on the deflection board ( where the flyback Is) at the top of that board there is a u shaped heat sink that has CP150 in side the "U" chances are the top of that capacitor will be budged and possibly CP114 as well see photo below.
Alot of people are not truly famillar with RCA TVs and I guess its natural to assume that the power supply is at fault. But the RCA will only do a 3 blink led error for a couple of reasons. The RCA ITC222 chassis can develope a no start situation from simply unplugging the power cord while its playing. Its too long to explain how to remove the board and flyback here , but if you send me a email to [email protected] i will send you the step by step instructions on how to remove the board and remove the wires from the flyback.which has pictures showing how to do it correctly. The other tech was only trying to help But the ITC222 chassis is something that doesnt have good service info available as its made by Thomson for RCA and GE But I have worked on that chassis well over 300 times so I am very famillar with the symptoms and causes.
I am trying to. But its impossible to post the detailed info with pictures here as the photos can only be less than 100kb in size and the info you need just to get the deflection board out correctly without doiing more harm is a large file with numerous photos. Its hard to diagnose a TV problem if not being done in person, but the 3 error code in your model is only caused by a couple of items and even slightly moving the TV when its on can cause the 3 blink error as that is the number one symptom of that chassis and it can be brought on while just watching the set. as its a component that has a high failure rate. You can take 1000 of the RCA ITC222 chassis and 95% of them will have that same no start condition with the led blinking 3 times and they will all need the same repair to restore operation.
By reading some of the comments I can see why you are confused, Your set doesnt have a ballast or coolong fan or a DM. As I stated unless you are famillar with this chassis you will not even begin to understand whats going on. You should be able just to feel the top of CP150 without removing the board. The wires will come out of the flyback, but you have to do it correctly as there is a plastic lock ring around the large red wire under the rubber boot that has to be released and slid up the wire before you can remove it. The black wire for the focus needs to be pried out carefully. But there are ceratin percautions that you need to observe such as grounding the end of the red wire as soon as its removed to a heat sink just to insure the High voltage if present is discharged.

Hey Pete, contact RCA, see what part they suggest for you to replace so you don't have to start doing any more damage to it. You can probably get a good deal if you go through RCA too, sorry your having so much trouble! Hope i've helped.
Do you smell any type of burning smell. Could be a transistor or capacitor that have blown
You will have to open the back and the fron t screws of the tv and the back will come out loose and you will get the access of the power board.on that main circuit board check out for ic number IC374JC that ic has to be replaced.also the capacitors which are slightly bulged at its top and which looks leaked from its top has to be replaced as they are faulty.replacing the component given will solve the problem.
Yes you need to check the capacitors on the board. Chance of it being bulged is more .
I'm slightly confused what part was pulled out. i would suggest first that you check the solder joints where the power plug goes into the board and any connector that might have been pulled. then check that when the board was pulled by the cord... that no other connectors inside the tv were disconnected or slightly loosened.
I recommend checking the bulb to see if its damaged. most of the time, this is the issue. make sure the cooling fan assembly if free of dust as well.
its not just the capacitors. the whole board went up. this was due to overheating. i suggest replacing the entire power supply board. replacing each individual parts will run up a huge repair bill when, replacing the entire board will be much cheaper.
this last ditch effort of power transfer is coming from what can be stored in the lone capacitor that is barely working. this was caused by insufficient air flow. overheating. this is a CRT rear projection screen. there are other components that will transfer power before the protect mode will shut down the set.
im sure the cooling system failed long before the power board failed.
yes, replacing the entire board will fix your issue. Follow me on this, the power board is crippled and can only with stand enough current to send the protect command to the main board. once this is done, the main board will switch the set to protect mode to prevent the fire that will occur if the power board is permitted to remain operational. this board has damaged circuitry and will need to be removed and replaced.

Its the problem of ic in the tv that has blown out,.
Unless u have very good electronics repair experience u should let a shop do this part replacement, u can ruin the circuit board from heat or improper/rough handling, a whole new board is around $600
Did you check the capacitors on power board?
Hi, the TV is in protection mode. This means that an internal fault had been detected, and the protection circuit on your digital control board started, activating the protection switch , that is the clicking noise that you hear (that is not the flyback).
Additionally , this TV is rear projection, and not a traditional CRT , therefore things are a bit different.
If you are a technician you need to start by leaving the TV unplugged for five hours or so. This may reset the protection circuit by draining power completely, in case the TV has no real fault.
If that does not help, there is need to test the PSU unit, the ballast board and the dmd board inside the TV, starting from the capacitors on power board. Also test the convergence ICs (STK) located on C board inside the TV.
If you want to DIY you will also need to get the service manual.
If you are noty a technician, just unplug the TV from main overnight and check that none of the touch buttons is stuck.Alos unplug any unit connected to TV.
If that does not help a repair will start at $150, and it is generally between $150 and $350, depending on parts needed, only in ecceptional occasions , like with a faulty light engine the repair can reach quotes much higher than this.

Hello.
If your wife move the tv, and the cable wire pulled out of the screw in connector that screws it to the back of the tv, that's not a problem at all. I say this because you say she tried to plug the bare wires back in- so you're left with your cable, and no end on it to screw to the tv, because that's still attached to the tv. THIS IS NOT A BIG DEAL!! I really doubt this event damaged anything in the tv. You can buy a crimp kit and put a new end on the cable (good ones aren't cheap, around $60 for the tool), or get the cable company to put one on.
The first thing you should be checking is the projection lamp. I'd bet money that it's toast. These lamps run VERY hot, and do not take well to being moved around while running. That's what the flashing is telling you.
I hope this sheds some light on your situation. Please comment, and please rate if this helps :)
Look for a small red push button along the back of the chassis. Push it in. It's the main reset button.
? What is the model # off the back ?
Does the video work on the RF coax cable input?
For instance,as a test,can you hook-up from VCR coax RF out
to TV coax in,put the TV on Chan. 3,play a tape and get audio and video?
Are you matching colors when trying the A/V inputs?Yellow,red,
and white out of DVD to yellow,red and white in on back of TV?
Then select video input on tv===dial "00" or use input button on
original RCA remote. Are you using original RCA remote that
came w/TV ? Do you have the owner/operator manual for the TV?
Sorry to ask so many ????? Let me know how it goes!! T.

ic what is that u said it has blown out ..how do u fix that..peter
what is the ic i posted my proplem on the rca u said its blown what is it and where is it on the tv
so i should check the capacitors on the power supply board first ..that board is where the power cord gos in ,,right .. how does that board come out ..peter
i posted my proplem rca should i check the capacitors on the power supply board first..peter
the coax cable broke off ....on the back i tryed to remove it ..then the tv shutt off now no power
so thats where i start with the capacitors on the power supply board ...how does the board come out .peter
can u tell me how the power supply board is removed ..thanks i dont want to break any thing ill remove it and check the capacitors .can u get back to me thanks...pete
can u tell me how the power supply board comes out i dont want to take it out till i know how ..then ill check the capacitors on the board
so from the coax insert being broken off that would blow the entire power supply board..i still have power going to the front green led like i said i press on the power button ..led flashes 3 times and 3 clicks ..where is that power coming from if the power supply board is shott..peter...
thanks i will take out the power supply board and replace it ...do u know where i can purchase one of these boards thanks ..i will let u know what happens after i replace it ..thanks peter
can u tell me where i can find one and how much a power supply board will cost .peter
so just replaceing the power supply board ...should sove my proplem ..just curious if the supply board is shott where is the power coming from to make the front led flash 3 times peter
no smelling of any thing burnt ..one of those experts told me the power supply is shott ..going to take it out and see
NO COMMENT
I JUST REMOVED THE MAIN FILTER BOARD IS THIS THE POWER SUPPLLY U WERE REFERRING TO ITS THE BOARD WHERE THE AC LINE GOS IN ..HAS THE 6 AMP GLASS FUSE ON IT ..ALSO 2 BIG CAPACITORS STAMPED L345 ON THEM THEY HAVE NO BALGING OR ANY BURNT SIGHS ...IS THERE ELSE ON THIS BOARD I SHOULD BE EXPECTING
y did that other guy tell me its the power supply board ..took it out 4 nothing i explained what happened like i said my wife was dusting moved the tv broke off the coax insert when the tv was on now no power blinks 3 times and clicks ..the other guy told me it was the main power supply filter board i took it off looks fine ..u think its the 150 capacitor by the flyback breaking off the coax insert would cause this how does those 2 wires come off the flyback do they come off from the flyback or where the 2 wires are going ..looks like in front of the set hard to see them ..peter
can someone please tell me what the proplem is i took out the main power supply filter board because one guy told me it was that ,,,seems to be okay no bulging on the 2 big capacitors no burnt sighs anywhere now another guy is telling me its the flyback or the capacitor 150 ...this is how it happened tv was working great my wife was dusting moved the tv when it was on ..then it shutt off now it has no power front led flashes 3 times and clicks at the same time sounds like the clicking is coming near or from the fly back ..what is wrong ..i took out the power supply filter board now i guess ill be putting it back in ..how does those 2 wires on the flyback release...so i can take out that board which the flyback is on and inspect the capacitor 150 4 balging .peter
can someone give me the right anwser please
can someone give the right answer please
what kind of site is this one expert tells u one thing and then another tells u another ..is it the capacitor by the flyback or the flyback itself or is it the main power supply filter board i already took out the the main power supply filter board capacitors look okay also no burnt sighs any where .can someone tell me how those 2 wires come off the flyback so i can take out that board and inspect the 150 capicitor ...peter
my email is [email protected] can u send me the pics and imfo on how to remove those 2 wires from the fly back .thanks peter
can someone tell me how to take off those 2 wires coming off the flyback peter
got the board out checked the 150 capacitor no bulging on top but there is a orange substance on the bottom of the 150 capcitor is that normal ..the substance is hard ..is that some kind of factory compond .can some one help me out ..peter
yes
all this advice i been getting hasnt helped me out one bot but cause more aggervation ..i did everything i was told to do by these so called expects ...with no success took all 3 boards checked out what they said ...my tv still dont power up..does anyone know what the proplem is ..if u read my threads u see what actually happened to my projection.peter
i know what im doing
my wife accidently broke off the coax insert in back of projection tv while dusting after that she tryed to jamm the cable line which had no end ,,bare wire .. back into the coax insert or u can say into a hole where it was once was ..after she did this tv shutt off now no power blinks 3 times clicks also at the same time i took out the 150 capacitor had it tested its fine i was told by an expert off here to do that ,,,i removeed the power supply board where the ac line gos in checked caps on there no balging ,,,can it be the main board where the coax insert was ,,,shorted out ..peter
can someone tell me how the patch lines they look like computer connectors but small release from the main board where the coax insert is ..would like to remove board and get the tuner tested ..peter
no reset button on back
no power on rca prjection tv 3 blinking lights coax cable broke off whule tv was on ...since then no power ..checked the 150 capacitor tested good took out power supply caps tested good is it the fly bac ,,the tuner shorted .. whats my next stepp ..peter
