Question about LG RU-52SZ51D 52" Rear Projection HDTV-Ready Television

1 Answer

Picture and Sound fade in an out

My TV is probably 4 years old and has never had a problem til now, we recently moved house and it is possibly as a result of shifting the TV, but when I turn it on the picture and sound come on for about 2 seconds, then fade out for 2 seconds, then come back. The TV will continue this for as long as the TV is switched on. Trouble is that for anyone to repair it they have to come and get the TV and assess it at the store, because I am unable to move it. Just an assessment is going to cost me $400, plus parts to repair it. If someone knows what could be causing it I will have a go at repairing it myself. Thanks.

Re: Picture and Sound fade in an out

4 years? Sounds like the lamp compartment is overheating. Take the covers off the right side (To Access the lamp) and the whole panel on back. This will give you access to the lamp assembly and fans. Get a can compressed air and blow everything out. Try to blow everything towards the right side and pull the lamp and do it seperatly.

I have a sony Vega 55" kdf-e55a20, It is 3 years old, and now the picture and sound fade away for 10-15 sec every hour or so and comes back! Anyone knows what the problem is?

Lamp is getting weak and TV shuts off and turns on itself because of weak lamp in TV that you see picture and sound fades away for some time until TV reboots.
Replace lamp in TV to solve this issue. Lamp replacement procedure is written in user manual and its an easy work.
Please buy Sony original lamp for your Tv safety.

We were watching our 42" widescreen TV (about 4 years old) and it suddenly popped and the screen faded to where we can barely see the picture. Can it be fixed or new TV?

The internal capacitors are blown out. About $250 repair. Or you can get service manual, soldering iron, VOM meter. and try and repair it yourself. Probably about $50-$100 in parts

RCA D52W20 - turns on and off, blue screen, tech said need picture tube

It does sound like the tube, have the shop use a tube restoration machine to rejuvinate the tube, and replace the eprom to try to correct the no power down situation.
