Thread: Olveia LCD shutting off for no reason

A week ago we had our power blink on and off several times over a 30 minute span.

Now, our Olevia 537 B12 has the screen go off after using it. Sometimes 15 minutes, sometimes it last an hour.

We then turn off the tv and turn it back on and it lasts for another 10 minutes or so until it goes off.


I have read a lot online about power supply boards, inverter boards, etc.

Before I shell out $100 for a board, can anyone shed some light on this?

Call a local TV repair place and see what it would cost to have them fix it.

Too much money. It is $100 just to look at it + $100 labor.


I have read numerous places that a new inverter board or power board will fix it, I just do not know which yet.


I would think that since the picture and sound goes, but the power is still on, it might be the inverter board.

I have no idea. I have replaced boards before with good results. I ONLY buy them If I get a deal enough to offset taking it to what a shop would charge though.

Good luck

OK, thanks for the help


Does my problem sound more like a power board problem or inverter board?

Reflash the tv's firmware using your pc. It's real easy. You'll need a USB A to B type cable, like the ones used between a pc and a USB printer. Mine has this version of the firmware: 537_B11_061218A. Since you have a B12, you probably need a different version. My Olevia 537H B11 only has a single HDMI connector, and I think the B12 model has 2...

I had the same problem with my Olevia 537H earlier this last year, due to an on/off on/off 6 times fast power problem, and the firmware reflash fixed it. Actually, mine was completely brain-dead, and wouldn't even power up. The reflash fixed it! See this for info, and the firmware you need:

Looks like you may also be able to get the firmware here, but you have to register first:
