Check for power supply trouble. The green LED on the front panel should light if power is getting to your TV. The "no signal" indication may mean no antenna or cable input is detected

Hi
I have met this problem with my LG.
I agree unplug from the power supply and find the correct input on the remote control. OK the antenna if that is your input. AV1 or 2 if you use ADSL.
Good luck

This problems ur tv are having are only can be causes by two boards,the tv power supply board or the tv Tuner signal board.The tv power supply board that the board where the power a/c cord plug into it.The tv Tuner signal board that the board where the incomming broadcasting signal wire plug into it.This problems very easy to fix.If it is the tv power supply board is the causes,because u can check the tv power supply board carefully u will find dying capacitors parts that will bulging up or puffing up on to it tops.U have all the tools and know basic electronic just replaced all the dying capactors for all new capcitors parts same micro ferit but the capacitors voltages like 5 or 10 voltages higher for better heat resistance for the life of the tv power supply board.If it is the tv Tuner signal board,very hard fix and determine where the dying parts are in this board,because this board is cover with many ICS chips on this board.If the tv the Tuner signal board is the problems best just buy the whole refurbish tv Tuner signal board for the replacement.Or u can tries websites like Shopjimmy.com,Ebay.com to buy the whole refurbish tv power supply board too,if u don't know how to or have all the tools to replaced those dying capacitors parts and also can buy the whole refurbish tv Tuner signal in these two websites too.

32" 32lc7d after a few minutes, flickers, then goes dark.


There are no fans in this model but it looks like either the backlights in the screen are breaking down after they have warmed up or a problem in the inverter board, again part of the driver circuit breaking down after a period of time. They inverter boards can sometimes be replaced seperatly but usually come with a new screen which if the backlights are at fault then the screen would need to be replaced.

Monitor goes black - green light stays on


Junk the TV. Mine does pretty much the same thing.

I'm thinking that our 'tremendous savings' at Circuit city was, in fact, the way Olevia unloaded these duds. These TVs should not be doing this. I tried working with the company, and they lied to me. That's why the theory about 'defective model dumping.'
