Well, don't feel alone.
Everyone is having the same problems with many brands of TVs.
Somehow built to fail after warranty. I'm sure it's a power supply related problem. From this link here, there is a Service Manual for the 42PF7320.

Page 27 says error code 7 means 8V6 supply.
I'm thinking it's the power supply for the screen. I can't 100% certain.

I have come to find out that in the 90's auto makers started installing factory amplifiers in their cars so they could use low wattage stereos in the dash. It's usually a blue wire off the stereo that runs the amp, maybe it couldve become disconnected? I also know that even if you put in an after market stereo, this wire must be hooked up or you'll get no sound from the speakers. hope this helps.

Same problem here. I repeatedly complained to XM but got no reply. I listen to XM in 2009 Sonata and it was just as bad.

XM is better than AM. Much worse than FM.

Follow the following steps to overcome this problem:

1. Locate the "Brake" wire (usually the pink wire).
2. Connect the "Brake" wire to a negative point, e.g. body of vehicle.
3. Test by playing a DVD and your problems have been solved.
