I have a polaroid tv TDX12811C I have sound but no picture

SOURCE: polaroid lcd tv sound only no picture

Hello dougie49

I would first check the back-light and the inverter. usually these are what causes the problems in LCD displays. If the inverter is bad most likely the back-light will have problems. If you need to replace the back-light 9 time out of 10 you will require a new display element.

I hope this helps

Thank you,

there might be some loose contact inside the board
check those chips for any fire r anything 
this could happen due to heat also

Your inverter boards need to be tested and serviced, these are circuits designed to control the light behind the LCD glass panel. It could also be the power supply not feeding 24volts too the inverter circuits. In that case the power board would need servicing.

Take it back if its under warranty if not get it serviced at your local repair center..

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
