20 Most Recent RCA P52930BL 52" Rear Projection Television Questions & Answers

If you're having the TV set completely turn off, then on, which will be accompanied by audible relay clicks, then this is a problem relating to bad solder connections on the main or convergence boards which will require someone with a sharp eye and savvy with a soldering iron. Most of the time, bad solder joints will be around the convergence amplifiers or in the high voltage section.

The convergence power supply is the small narrow board which is held in place with a couple of screws. I am attaching a pic of the board yours may be slightly different

Replaceing the Audio output may solve the issue, worse case is the small signal board will need replacement

change the lamp with new one

hello my name is rico i work on tvs sometimes. you need to remove trhe screws around the back of screen and the front of the tv, need to remove front panel screws around. please feel free call me if you needd more help with this problem. my phone number is 602-810-7149

From the symptoms you have described it looks like you have a bad deflection IC or a bad color wheel both of them are capable of causing the high pitched noise you have described. What exactly do you mean by "convergence problem". Did you have false colors colors. ALso did you have any whirring noise before it turned into a high pitched noise? Please answer these questions so that I can help you isolate the problem and fix it.

That model uses one IC its the STK730-130 you can get the replacement IC at www.tvrepairworld.com

You will need to reset your v-chip, refer to your manual for exact instructions if you do not know the code, or call RCA to get it reset.

You can adj. from the front panel of the set using the channel and vol. buttons,if the set you have has a ptk 195 chassis,check and make sure you have adj. projection tv in screens of the menu,in not the convergence power supply has failed,replace the reg on the board,part number is 215530

Had the same problem unplug the tv for hour. Had ours at the tv repair shop and it worked fine there brought it home now we have a great picture but no sound.

You have probably blown one of the convergence ICs. Effectively the easiest thing to do is replacing the whole convergence board, so that no soldering is involved.

Here you can buy a replacement convergence board, just select your model.

Let me know if you need further help.

The beeping noise is usually related to the Horizontal out put transistor or flyback being faulty or one of the coils are loose near the flyback. If you remove the rear cover without touching anything can you tell if the beeping is coming from the large transformer with the red wire coming out of the top or is it coming from a black transistor on a aluminum heat sink.

A clue to what is wrong is by looking from the back (taking the back off) and looking to see if the three picture tubes have any yellow glow at the bottom of them where the three identical boards are located on each tube.. If you have no glow there you possibly have a resistor R4703 open. It is a 3.3 ohm resistor and feeds the voltage to the filaments in each tube where the glow is suppose to be. If you do have the glow the problem could be much more complicated. Another to check is to see if the menu comes up on the screen. You could possibly be in the wrong input mode, Check your input mode with the input button on the remote The number R4703 is a location number to identify where the resistor is. This is all I can tell you that would not require much more complicated procedures requiring a tv repairman to look at it. If you have an ohm meter you can check R4703 but it must be checked out of circuit. (or at least one leg loose) Hope this helps

Don't understand why, perhaps rca contracted microsoft for their programming, but when I unplugged the TV and it rebooted, everything is fine. I still am concerned about the warning on the back.

RCA's are known for bad Horizontal output transistors, Flybacks and high voltage splitters going bad on these models. That hum/buzz is the powersupply trying to turn on.

The convergence power supply has failed,replacing the 215530 reg.on this board will restore the convergence menu,this board is on the right side facing the back or the set mounted on the black plastic above the board with the 6 heat sinks on it

The flyback and horz output has failed,if its a ptk195 chassis,most likely the part numbers are 239111 and 237470

First unplug the unit and leave it for about 5 min.,then plug the unit in and see if you have sound,if not check to see if the speakers are on in menu,if they are on,sounds like the outputs or maybe the e prom.
