Blank Screen


I had this problem on my 42" Philips. Just got it yesterday and worked fine on the tv stand. As soon as I mounted the TV to the wall via wall mount system, I had the exact same issue you did. Figured it out today.

The wall mount was putting pressure against the center of the back of the tv (tv set had a slightly rounded back plate, and the mount was a flat plate). As soon as I put spacers (part of the wall mount hardware set) between the wall mount braket and the tv so there was no contact except at the mounting holes, the tv worked fine.

My theory is the pressure pushed the tv back plate against some board components which caused them to overheat (no air flow); or put pressure on internal connectors. I dont know.

Hope this helps, may not apply to your situation.

That's a very old model to be only 1 year old?

It needs a Z-Sustain PCB anyway.

Lg lcd tv screen goes black but the sound still works 52lg70 screen goes blank, sound still works. i can change settings but cannot see the menu so the tv is still working there is just no picture.


This sounds like a mainboard problem. Unless you do not see a back light flash when you turn on the TV, which may mean it is an inverter board problem, this is most likely fixable by replacing the mainboard.

No sound from built-in DVD player on TV?


It sounds like the audio cable from the DVD drive may be loose or damaged. Did you wall mount the TV and this is when the problem started or has it always been like this? If its under warranty, contact the helpline on 0871 2000 463, be warned, if its becuase the cable is damaged by a wall mounting screw, its clearly evident and they will charge for repair.

TV SCREEN GOES BLANK


Yes your inverter is bad, I have the same problem my set is about 1 and 1/4 years old. Because Olevia makes a terrible product there inverters are attached directly on to the panel, which means they will only sell the inverter along with the panel i.e $700+ to replace + $100 dollars labor if u don't know how to fix it ur self. I am currently searching to find the manufacture that makes the inverters because olevia will not disclose that information. I believe it is darfon, if so the inverter should cost about $150-200 depending. If you dont believe you can fix it ur self ur best bet is try and sell the set for scrap take ur $100 or so dollar and buy a quality product! Oh and dont call there support they will tell 10 different things before u find out this long for seen truth!
