JVC P100 Repair

[colorfixer]

Hello all,

I've acquired a JVC P100 2" portable TV/radio combo. The unit is virtually spotless, however the poor little guy has a couple of issues:

1. TV tuning range on VHF and UHF will not tune across the band, it seems stuck on a small portion of each band even though the tuning potentiometer (it uses a voltage controlled tuner) is turning from end to end with no slip.

2. The radio section works on FM but not AM.

Without a schematic I'm stuck, and the dial cord is strung throughout the unit in a merciless way, making me aprehensive to jump in unguided. It seems that symptoms along these lines are common as I've run across similar issues attempting to scour for a diagram.

Does anyone have a schematic that they could post?

Thanks,
