    Why would I have a POWER supply prob if I have sound?

    What is inverter?/? Thanks so much for any help. I can't buy a new one so I'm just screwed if I can't resolve.

You have a power supply problem or an inverter problem. Best to have it looked at by a svc center.

    Answer to how could it be power supply? Because there are 3 sets of voltages developed by the power supply and only the voltages for the inverter which supplies the high voltage are in question, not the 5 volts for the cpu or 12 for audio. Only the other 12 or 24v for the HV.

HISSING SOUND WHEN TURNED ON. EVEYTHING WORKS OK.


Hissing sound is one or more leaking capictors. My suggestion is that if you have an extended warranty then get a repair guy to come out and fix it right away before you extended warranty expires.

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

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.
