Standby light is on,but my olevia tv will not turn on.


No, someone will need to open set and check voltages etc and also look at power board to see if any puffed up bad caps like these:

Olevia 537H power button stays on tv randomly turns on


I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.

My Olevia TV turns off on its own when I turn it on after 10pm...please help!


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

I have 19" Olevia LCD TV and the red power light comes on when you plugged it in but the TV DOES NOT power on


You only have 5v standby voltage circuit working. The problem can be i nte main power supply or the main control board that send the signal to the main power supply to turn on. Those are the two place to look for.

Won't always turn on


These olevia tv's were only made to last a few years. the company has gone out of business. they took the money and ran.i also have the same exact problem. the power supply board needs replacing and i can't find one. repair shops want almost 300 to fix but it isn't worth it. thow away or if your lucky enough to find a power board fix it yourself for around 100. i t k mine apart seems easy to fix.
