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,

Henry A. McKelvey

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.

While watching the TV the picture suddenly went out - still have sound. Turning the TV off and on again does not help - the POLAROID Logo displays, but when the station connects - still no picture

You most likely have bad power inverters in these TV sets. The power inverters are what power up the backlights in these sets and is a very common problem.. Only the power inverters as a complete assembly can be replaced but is not really a job a user, as only trainer repair persons should attempt this repair because of the high voltages involded and the expense of the part. You can contact Polaroid to find out where you can get this set fixed. Good Luck
