Backlight Flickers Olevia LT37HVS

I would be glad to give you my power supply. How can I test it to see if it is defective? I have the problem with the TV flickering, and I have heard it is either the power supply or the inverter. If I hook I a volt meter to the power supply, what should I see that would tell me it was defective? Just low voltage, or something else. I'm a hacker not an expert. Thanks for the help!!!

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

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.

37 inch olevia hdtv screen keeps going blank evry ten minutes or so. to get it back must shutdown and restart


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

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

My Olevia LT37HVS 37' was working fine all day and turned to black screen.


It is either the fluorescent backlight source for the LCD panel or its associated power supply failing.

Syntax Olevia 30" LCD - blue screen, then black screen, sound is on


you have a broken inverter board. I have a LT30HV, and it had the same problem. The inverter board supplies power to the backlight. Swap it out with a good one, and you're back in business.

To test, take a bright flashlight and point it at the screen just an inch or so off the surface. If you can see your picture, then you have a blown inverter.

it may not be worth fixing it. Wait for a good sale on a new one. My inverter cost about 150, and it was a remanufactured part. Not as good as the original part as it flickers just a tad. I had to take the entire TV apart, with pieces literally everywhere. My cats loved it.
