Question about RCA D52W20 52" Rear Projection HDTV-Ready Television

Open Question

My TV won't power up. If you try to turn it on, the green indicator light on the power button comes on, then sometimes you hear a squeal from one of the circuit boards inside and then the power indicator light goes off again, but the TV never comes on. I pulled the back off the TV but I don't see any discolored components or connections on the circuit boards...no obvious problem indications.

I had a similar problem with my 42 in Philips LCD HDTV.


Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.


Here are some options for you.


1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)


2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found at tv-part.com but supplies are limited. I would definitely shop around though.


3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.


This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.


Hope this helps and if it does please rate it accordingly. Good luck.

3 blinks indicates lamp door is not on or has not been reinstalled properly. This also could mean the lamp door switch has failed itself. Try removing the lamp door and putting back on, if that doesnt correct the problem then I recommend having the switch replaced.

Hello,

My LOEWE CAL 232 will not power up. When the power button is pressed, the monitor turns on, with the LOEWE on the monitor, then the TV continues with the previous activity (antenna, DVD, VCR etc.). Now all that happens is

1. the red light comes on

2.after about 1 second the green light turns on for about 12 seconds

3. the the green light turns off for about 1 second

4. then the green light turns on again for about 12 seconds

and this continues until the power button is pressed to turn the TV off. During this time, the monitor does not turn on and the only sound I hear seems to eminate from the power button.

Any thoughts?

CTR Television will not power up


What has happened is that the horizontal output transistor has shorted. The squeal you hear is the power supply running under a heavy load. The picture narrowing or being distorted indicate that the horizontal output was not operating clean. Something in the output section was not as it should be. Possible short in the output transformer/tripler unit or something loading down the secondary voltages generated by the horizontal output. You will need a tech to figure this out....If you are not a tech, then this ones a goner as far as fix it at home goes.....If you are a tech I might be able to talk you through the repair. Have someone remove the horizontal output transistor and I bet the squeal goes away.

Tv wil not turn on


The horizontal output transistor is most likely shorted, it's a 2sc5588 Rca Part # 259899 and there are a couple of subs available for that too.
The slight squealing you hear is the feedback voltage on the hot transformer as the B+ tries to increase and the s/d circuit cuts it off. Not an expensive repair...
Good Luck!
