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.

Let verify first to narrow down to where the problem can be. First, make sure the MUTE or SAP function is not activated, then check the on screen sound set up menu to make sure the speakers are not set to OFF. If the setting is OK, then attach the powered PC speakers to the Audio Line out RCA jacks (Red and White) to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. Please post back what you find.
