Olevia 26" hdtv - sound, no picture

Set is about 1.5 years old, and has no picture. A cable tech said he thinks it's the equivalent of the picture tube going bad (crystals?). If so, is it worth repairing?
Thank you.

If this is an LCD TV, it's probably the backilight inverter that's gone bad. Without the backlight, the display works but you can't see it. It may be possible to repair the set by replacing the inverter. Several sites sell boards removed from other sets (the TV version of an auto junkyard). One of them is shopjimmy.com. You can also try a Google search for "replacement inverter" for your specific TV model.

If you can find the replacement board, it's not difficult to change. It's a matter of removing the back of the set, unplugging the cables from the old part and connecting the new one in its place. Rather than relying on the cable tech (they normally don't know anything about TVs beyond where to hook up the cable), you might want to get an estimate from a TV technician if you don't feel you can attempt the repair yourself.

If an LCD TV has sound but no picture do the following:

Use the source button to ensure that source is not set to the wrong input.

Try unplugging power cord for ten minutes, to ensure it is not a setting problem.

Check all the video cables at the back of TV.

Check Light /Color settings.

If problem persist and does not depend on external receiver or settings, then it is likely an internal fault.

If it has sound but no picture then one of the following parts is faulty, and must be tested and replaced:

The inverter is the high voltage board that provides variable power to the backlight lamp. This is the most common. When inverter is faulty you can get no picture, or a very dim picture that can only be seen by pointing a torch light with a 45 degree angle on the LCD surface from very near distance.
The inverter must be tested by reading voltages with a multimeter.

The LCD ribbon cable/LCD display and connectors.
This is quite uncommon, but happens. If the TV had been hit or moved the LCD cable may have slipped out, or the LCD connector may be damaged.

The LCD controller board.
This is the board that controls the video signal, it is difficult to test, as there is need to read determined values on IC pins. To test this board you need to purchase a service manual and follow the troubleshooting diagrams on service manual.

Input/Output Signal boards.
This are the boards where you connect the video and audio cables, if a signal board is defective, then you may get no picture on particular inputs located on faulty board.

If under warranty contact the manufacturer ringing the number on the user manual.

If you want to repair at your own expenses, just locate any good qualified repairer.

Olevia 37 turning off for no particular reason


I suspect that the main power supply is trying to self-destruct; what you describe could be the switching power supply struggling to stay up and running. It isn't the cable company's problem.
FYI: Olevia has declared bankruptcy so you may not be able to get any help from them.

Crackling noise


I think I have solved the problem. I dusted the tv completely. Then took the cable box and with a hair dryer in the cool setting blew out the interior circuits to try to remove all dust. Turned the set on no more crackling. Thanks for the posting.

Olevia 26


This happened to us also. Tech support says it is a problem with the mother board power supply. Over 200 to fix plus shipping and labor costs??? Not worth it! Sounds like poor quality. Ours was just over 1 year old too. I would not take another chance on Olevia products.
