Olevia 237V S11 Backlight Problems

The backlight on my Olevia 237 flickers all the time, it give the picture an annoying strobe light effect. I have replaced both inverters and there was no change in operation. I have replaced transistors and capacitors on the secondary side of the power supply with no change in operation. I haven't found a replacement power supply yet to try. What else is possibly causing this problem? Has anybody fixed this same problem? Thanks.

    I ordered a new power supply from Olevia, their customer service couldn't get much worse than it is right now. New power supply fixed the problem, it cost $98 plus $10 shipping. It only took me a couple weeks to get a hold of somebody to order my power supply.

This sounds like a defective batch of fluorescent backlight sources; have seen this complaint before.
This may be tough to acquire since I don't know how standard those are across the industry and Olevia has filed for bankruptcy so you can't count on them.

    I would really like to have a bad supply in possession since I once had an active business repairing switching power supplies some years ago and suspect I know what is causing this type of failure.
    The actual model origin isn't important and I haven't had the misfortune yet of having one of mine fail.

    If you would be willing to let go of yours (assuming you still have it) I would be willing to send you a check in advance for whatever residual value you place on it and a few bucks for packing and shipping it.
    I don't really have any wish to retire from retirement so it would be a matter of curiosity more than anything.

    And, as an added incentive, I would return the supply to you if it can be repaired so you can replace the one you just bought with one that will most likely never fail. 
    I know these beasts.

    If this might be of interest, please email me at the (corrected) address below: (small 'L' in lycos, not an 'I')

    Thanks -

I have a 42" Proscan

It sounds more like a backlight problem to me. The first thing I would try before tearing the set apart is simply unplugging it for about five minutes and plug it back in. TV's do weird things sometimes and need to be reset. Odds are, if you have to open up the TV, there's not a whole lot you can do anyway. Check the backlight on signal and also see if your inverter is working. I would suspect that if you're strobing your backlight is probably dying. In that case all you can do is replace the panel; you could try finding a replacement backlight and installing it, but I wouldn't advise even trying this. Replacing backlights is quite a task if you're not familiar with televisions. Anyway, best of luck.

Sounds like you have an LCD tv with backlight problems. Check power board for domed capacitors and replace them. next check connections on the inverter boards. they are on the sides or just one side. Becareful there is high voltage output from these boards. If the cable from inverter board is not good to the screen you can get a strobing. the inverter boards may need replaced. or cales to screen may be bad. The panel also could be bad.

I have sound but no picture on an Olevia 237V

If you get no picture on all inputs (TV, DVD, ETC.) then the problem can be in the backlight inverter board or the power supply that supplys the power to the inverter board.

Flashing picture

I had the same problem with my 237V, I had to replace the power supply to fix the problem. I believe when it would work the output voltage of the power supply was around 19.2v. When the screen started to strobe the voltage had jumped up to 21.5V. A new power supply fixed it for me but now I think my main board is on the fritz.

Olevia 237V Backlight problems

Voltages do not dance around and should be constant and within stated parameters.. The board producing those crazy readings is the issue.

Check inverter supply voltage, (should be constant and stable) if found ok, then inverter or back-light tubes are suspected.
