TV about 2 years old. Purchased from another no warranty. Working fine one day the next day turned it on...power light blinks...burning electrical smell... but no sound or picture. Tried all the suggestions in the manual. HELP!
-   Model hd52w55 --It has no picture or sound. It just failed to have a picture or sound one day.You can hear it come on with remote or front power button. The light on the front blinks about three or four times then stays on.You can rasie or lower the volume and hear a thumping sound response from speakers. With the back panel off you can see a green light and the fan running on the side board where what looks like a hard drive is.I'm able to replace parts on electronics and pretty well know the safty procedures to follow.Any help on where to start.Thanks-   bob523
Im sorry to tell ya pal, this set is famous for the Flyback transformer to go bad, and alot of these are not available anymore. I would check first with a local RCA shop. Then I would contact Thompson Corp in Canada to see if they can assist you as a two year old set should still have parts available. Good Luck
Read comment by techman. On such a large set it must be devastating. My advice to everybody buying second hand goods of any type is to look inside if possible before you plug it in to the mains. Check for bodge-ups and missing screws and things taped due to damage and bad soldering. Also there may be incorrect components which will work but are overstressed. Make sure the inside is clean so that you can see everything. With great care and not coming close, and if everything is held in place, you may switch the set on with the back off to observe if anything is actually overheating. Do not poke anything unless you know what it is (using a long piece of dowel rod).
