Attempting to repair a JVC AV-31BM4 TV, main board label reads SG61026A
with tuner CEEM245. First problem with the set was a red tint on the
picture, found a 15K resistor was open on the crt board. Testing the
set further revealed the tuner problem.

The set will not receive any tv or cable channels through the tuner.
32V, 12V and 5V at tuner look ok AGC reads 7.2V. Autodetecting or
manually adding channels didn't make any difference. The AV jacks work
so using an external tuner is a possibility, but while I have this set
apart on the bench, any ideas or known tuner problems with this set?

Thanks,
Tim B.
