When it is dead like that, first place to check will be the power supply module, need to do some visual inspection for burnt spots, bad caps with leaking/bulging tops, fuses, etc.

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

SOURCE: olevia tv start on audio on, no picture

that is a sign of a possible power problem it may be fixed by exchanging the powersupply or some other iternal panel the best way to troubleshoot this is by getting a service manual if your inclined electronically. basically voltage checks and identified fualty circut or board
this happens with lcd and plasma panels the circut may go bad and loss the proper voltage capacities and it cuases the tv to go into a safety circut like this.
have it serviced or check by a qualified lcd and plasma shop they may have the parts you need for it.

goodluck hope this helps.

A good idea here would be to take some digital photos---find a photo sharing site on the net and post them there.

copy the URL or location of them and post it here---seeing what it looks like might point to where the problem is.

Hi, My Olevia 42 inch, model342-B11, has a problem with its picture. At first I had vertical lines running down the screen, then it turned into small squares. What do you think is wrong with it?

Parts are hard or impossible to find for this brand but it sounds like the "main" board which processes all signal in and out of the display.

Pixels are going out on an olevia 42 inch tv. can they be repaired?

What do mean by pixels are going out? Do you get scrambled pictures/rolls/ pixelated?
If you can get parts, then anything can be repaired. Does it look something like my pictures here?

Picture rasterization

It sounds like the LCD controller board problem, usually if you cool it down the problem will go away, and comes back when it heats up again.

42" TV has sound but no pictures

yea it sounds like a main-board or inverter board.. sounds like the panel of the television is loosing power and you are still getting sound..

Olevia did go out of buss.. but i know this 3rd party repair center called Amergence technology is offering to repair Olevia's. But the thing is that the whole television will have to get service they don't sell parts so you might want to give them a call and get an idea on the repair quote.. 866-965-3842
