Question about Olevia LT23HVX 23 in. LCD Television

2 Answers

Powers on but no video display

I have an OLEVIA 323 S11 television that suddenly stopped working. When powered on you can see the screen light slightly but I cannot change inputs nor do any menu screens appear. I am utilizing the HDMI input from my PS3 and an analog signal from my DENON receiver for all other video.

I think I have a similar problem. The screen lights up, but I have thin vertical lines, mostly washout out by white toward the top. However, I can hear the TV programs even as I surf up and down through my channels.. If I change inputs, it seems to cycle through each mode, and I am able to get back to the TV input, but the display does not change.

If it is an LCD (not DLP), there is likely a problem in the power supply /and or inverter circuit that drives the ccfl backlights. It is sensing a problem and shutting down to prevent further damage. Bad electrolytic capacitors are a common fault. They usually bulge at the top and chemical leaks out. These degraded capacitors wil cause unstable operation, and shutdown. is a great resource for information.

My Olevia 323-S11 will not turn on

Most likely you have a fault in the power supply or main board. I would start with checking the power supply capacitors.

Can you see a picture and is it just dark/black or is there no picture at all?

If no just very very dark, check the back lighting for the unit.

If there is no picture it could be a few other things.

Power button takes longer to turn ON.

Bad capacitors on the power supply and or motherboard. They use cheap capacitors in those units and im surprised its lasted as long as it has.
