Question about LG Televison & Video

2 Answers

I have a 52 LG CTV model 52LG60-CA.ACCSlJM. I turned on the TV, sound O.K. no picture and no OSD. Turn TV off and back on within 30 secs. TV runs good.

The TV was built in 2008. Symptoms are the same if turned on with remote or turned on with TV switches. Can you please help me solve this problem. Thanks Dale

    There is no bulging capacitors on any board. Do you have any other suggestions.

    Thanks

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should troubles shoot. Contact any service technician. The circuit will differ with models and versions.
Type in the brand name of your device, in the search box [at the top right] of the display window and the Search will start at once as you type in, and will show you all the related posts. It will make surf easy.

I have lg 52lg60,when I turn on it's clicking power indicator on and off.I check the power supply capacitor looks like ok.how can fix this?


My Westinghouse led tv did the same and seems like it isn't working any more. I never pursued the reason but by how it acted it seems like a cold solder joint, or a minor capacitor problem near the light

I have an LG DLP. that turns off after 15 -30 seconds


If the second light is blinking to orange or red, that is usually the lamp indicator light on an LG DLP tv. That indicates your bulb needs replaced, or something surrounding the bulb has failed (like the cooling fan for the bulb for example) IF you have a spare bulb handy, I'd replace the bulb, keeping in mind if you touch any part of a new bulb with your bare hands, you just cut the life of the bulb by more then half.

I would call LG and have them assist you with a repair. The most helpful number is 877-543-8325. It doesn't matter if you are in or out of warranty.
