My 32" Olevia lcd when i turn on thre tv it will work for a couples of minutes then then screen turn very dark with images,sounds ok,then it will change back and forth.

The tcon board is responsible for the image on your screen as well as any anomalies you see.

my olevia a 232 s12 2nd hand tv . gift from a relative wont power on .just had the blue light on.i was able to reset my 32 inch olevia by pressing and holding down the power button much like a computer to reboot.might work for you.

if you look closely can you see any picture what-so-ever? grab a flashlight and check to see if you see a very dark image on the screen. if so you need to check voltages coming from power supply to the inverter board - if the voltages are good - order inverter boards - if you can see the backlights on - check your Main and tcon boards..

thanks,

If there is still about ? 24. Volts coming from the Power Board when it goes dark, it will be the Inverter board that needs replacing. If not, it is the Power Board that needs replacing. The Voltages should be written next to the sockets & plugs on the Power Board.

I had the same problem with the exact same TV. I took it to a local TV shop. My problem was fixed by replacing the T-Con controller board. The cost of the part was about $85 and labor $125. There are no "new" parts out there for Olevias because the company is out of business but I did find a part pulled from a "damaged in transit" TV. It's a personal decision (assuming the parts can be found) as to if its cost effective to repair the TV.

Mine is kinda tempermental also. When it won't come on or turn off with the remote ,or gets a double image on the screen,I have to unplug for a couple of minutes and then it starts to work. Don't know why.?
Give it a try

I would suspect overheating of an electric component in the power supply of the lamp (backlight) of your lcd tv. bring it in for repairs.

I have had the same problem with my daughters Olevia...232-S13 out of the blue ti just decides to not turn on...blue light lit where the on/off button located but no sound and no picture....i guess the saying "you get what you pay for" stands clear here.......very upsetting.....

youre screwed. panels for tvs cost almost as much as the tv, and they are very hard to replace. i suggest you sell the parts out of it.

This set has had a problem with the LVDS cable from the Main PCB to the panel. The wires are delicate and the connection is not that great. Sometimes unplugging and reseating the cable does clear intermitent problems like yours up. Good Luck
