Teak TV ct-M687;HDTV   Any advice please.
All channels can be somewhat tuned but none of them look good.
Picture is distorted/wavy and the sound cuts in and out for about 5
minutes from when TV is first turned on.

I have tested with a VCR and cannot receive stations from the RF but
this is confusing me: I switch the VCR to test and can get the 2
vertical white lines by tuning the TV to channel 3 (via RF) but cannot
receive anything.
However I do get perfect picture and sound via the scart connector.

So far I have resoldered etc.; I have B+ at 12.11v and various voltages
on other pins at the tuner but no reading on the IF pin.

I would appreciate any thoughts on narrowing down the problem.
Thanks
ALI
