Question about Olevia Televison & Video
Posted by Anonymous on
I have found a solution to the scrambled / freezing picture for the 65" Olevia LCD T11. At the recommendation of 3D electronics in plano TX, I installed a 200mm fan on the back cover with the air blowing directly on the CPU of the main / video card. I had to cut a whole in the back cover to mount the fan and actually left the bottom panel off to let more air flow. There are some spare 12v terminals on the second power board on board furthest from the main board. I cut the whole out with a jigsaw and had to extend the power wire due to the length required.

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.

Try viewing the screen from a flat angle with some light source at the opposite angle while turned on.
If you can see image 'ghosts,' then either the backlight fluorescent or the high voltage inverter for it has failed.
This may not be cheap to repair but I wouldn't consider it a death notice.
If you or a tech finds which it is, you might try here for the board:
These will be 'pulls' from mfr. overstock or disassembled sets. They do offer a warranty.
If the backlight has failed, I'm pretty sure a tech will know where to get them.
