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

    The inverters power the backlight section to make the screen light

I have a sony Vega 55" kdf-e55a20, It is 3 years old, and now the picture and sound fade away for 10-15 sec every hour or so and comes back! Anyone knows what the problem is?


Hi,
Lamp is getting weak and TV shuts off and turns on itself because of weak lamp in TV that you see picture and sound fades away for some time until TV reboots.
Replace lamp in TV to solve this issue. Lamp replacement procedure is written in user manual and its an easy work.
Please buy Sony original lamp for your Tv safety.
Thanks.

It sounds like feed back issues or maybe your rca plugs are plugged into wrong inputs it should be connected to audio output on tv and ensure the same color plug in connected to both the ins and outs on tv and audio receiver.

My polaroid has sound and picture problems


This is a well-known problem with many Polaroid FP displays. Eventually, the picture will simply go black, rendering the TV useless. The solution is a new control board, ~$400.
