20 Most Recent RCA HD52W140 52" Rear Projection Television Questions & Answers


Thats caused by the Small signal board. which is the green board on the right side with all the inputs on it. Thats a very famous issue for RCA rear projection models.

set has the 3 strikes and you are out= will try 3 times and then goes into shutdown===you have either a power supply problem or a short somewhere.

The high pitched whine is indicating there is a deflection board issue which is preventing the set from powering up. Rplacing the deflection board should solve the problem. You can get the deflection board from www.tvrepairworld.com

I have the same problem, push button to turn on tv but it only does a click like it is going to turn on and then another click bit it wont turn on. Finally a red light is just blinking.

Any suggestions, is there a freeze button or code that I need to push.

Oops, nevermind. It's right there up top.

First off, try a TV reset. Leave it unplugged for 5+ minutes then try again.

If this doesn't work, I would recommend contacting RCA. There is no way to contact them as far as I can find, except for an online form to their customer service (there may be a contact number in your TV's manual):

HOW TO CHECK ALL KINDS OF REMOTE BY A CELLPHONE


Take a cellphone with camera this is the latest gadget to check all kinds of remote control If its ok. In your cellphone open the camera then focus it infront of the remote control were the IR led or eye is located. Then press any button of remote control, you will see it glowing from the remote infrared eye while pressing any button If its okey, If the remote is defected it will not glow...

From your description ..actually this is a common problem and no simpley replacing the resistor will not fix it. this chasis has a problem with what is called the high voltage splitter.. there was a number of these made with a defective splitter. RCA HAS ISSUED a service bulliteen for certain models and serial numbers. the board and the splitter is generally replaced. (I just worked on one of these 2 days ago and got and order in for the parts) ......just reread the tech bulliteen.. the spitter which develops a crack is rca part number 258512 the resistor or the part that burnt is resistor a common 27k 1/2 watt 10% carbon resistor

Hello rsherrett1,

Ok first of all the only way the trippler could have caused this was if it shorted, and you would have known if that happened, because of the fire that would have occurred. So let's go back to square one. did you check the primary power supply in the back of the chassis? check it first for a blown fuse. I you can not find that then disconnect the power connection to the high voltage board and secondary power supply (switching power supply) and see if you can get the supply rail to the secondary board up (you will need a schematic to see the voltage values that should be there. Now if that fails to produce results you will have to assume that the secondary power supply is the culprit (it usually is). The funny part about this is the one component no one ever tells you to test is the one you should test all of the time and that is the IHVT (Integrated High Voltage Transformer) some folks refer to it as the "flyback" transformer. Now one of the biggest problems happens at this point there are three tests that you have to run the equipment needed is a s follows:

1) an oscilloscope

2) Universal Signal Analyzer/Generator with Ring Test ports

3) A capacitance meter or a LCR 103 (I prefer the LCR103)

4) an ohmmeter

Now here is what you need to do to test the IHVT

1) Remove the IHVT from the circuit board (desolder it)

2) Remove the HV cable clamp (holding the HV cable to the base of the IHVT)

3) (Test 1) Perform a resistance test between the posts of the IHVT looking at the schematic to see which posts are wired to each other. (now this test is only good for pointing out open coil windings not shorted coil windings) if this test passes (no opens) go to test 2

4) (Test 2) perform a ring test of the IHVT. Now this is why you need the Signal Generator with ring test ports. Connect the cable from the ring test ports to the primary side of the transformer, see the schematic to determine the primary os the transformer (the side connected to (actually between) the Horizontal Output transistor and the power supply. turn the ring test actuator fully counterclockwise, turn the test selector to ring test and slowly turn the ring test actuator clockwise until the screen reads greater then 10 rings, if ten rings can not be achieved then the IHVT has a short in it and should be considered as bad and in need of replacement. if this test passes go to test 3

5) (Test 3) The last test is the capacitance test. This test is a test of the internal capacitance of the IHVT. This is measured from the HV anode of the transformer to the ground post of the transformer. connect the negative end of the capacitance meter to the ground post of the transformer and the connect the positive end of the capacitance meter to the anode of the IHVT (this is the end that the cable was removed from, You will have to use a probe with a wire attachment to it to make contact with the anode connection in the IHVT. Once that is done the capacitance meter should read around 2.7nf or above. A reading of .3nf means the capacitor is open. Note: However certain flybacks may have the value of 4.5nf, 6nf and 7.2nf and sometimes the internal capacitor pin is connected to circuits (feedback) instead of ground, so be aware of this when testing. If this test passes then the problem is not the IHVT.

However if any of these test fail then the IHVT is to be considered as bad.

Now if the IHVT is good, then you will have to test the following components and their respective circuits:

The Horizontal Output Transistor, The Switching power supply MOSFET, The switching power supply transformer (perform ring test just like the IHVT), and pay special attention to the capacitor on the 6 volt rail (This capacitor is known to go bad often) as seen on the circuit board, The schematic will have all of the part location numbers as seen on the board.

This is a logical start as opposed to the shotgun approach a lot of forums seem to lead to. Let me know if this helps you.

Thank you,

Plastic Piece? WHere is this piece located ?

Sounds like you have a bad tuner. The most likely cause on these RCA's is a loose RF antenna input connector. A bypass for now is if you have a VCR use it as the tuner and then connect it to the TV using the composite video inputs. If that faisl as well then you have a bad signal board.

Your flyback has shorted out and thats whats burning the resistors cahances are the HOT is shorted as well. You can get some information at the following link for RCA problems. Just leave them an email with your model and what the problem is

see if there is any liquid on the boards, then i would tap with a plastic device on the board see if there is a loose connection
