My maxent TV has no picture and no sound


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.

Dark picture on wega lcd


Yes, if this TV has a bulb it is likely to be the bulb.

I am not familiar with this exact model, but other LCD Projection TV will show dim picture after some time. Expected life of the lamps is about 2yrs. After 2yrs the picture will become dim. After 5yrs I am suprised it is even working.

Dirt doesn't cause this problem unless your are a smoker or have the unit "literally" outside. DO NOT try to clean it or let someone tell you to do it because it will cause more problems than it fixes.

Sound but no picture.


Is this a 3-gun projector style or an LCD?
LCD has a lamp . If its a 3-gun system, then it's probably in the High Volt section on the unit.

Time to get a tech to troubleshoot it in person
