I had a 25" sony which could not lock on the picture. It would scan between
snow and good pix (any channel) but never lock in. I got some good advice
on another NG sci.electronics.repair, a website repairfaq.org and another
forum for the "nuts and volts" magazine (several TV gurus there). In the
end, someone pointed me to the exact coil in the tuner with a cold solder
joint. A little dab of solder in the right spot fixed on the first try. My
TV was of 1984 vintage, back then there were several well known (to TV
repair guys) failure trends.

Keep asking but not in a home repair NG be a little more selective.

When you do, also include if the aux input works. If it does, the problem
is likely in the tuner, if not, a number of other things may have gone bad.
Snow does indicate that most of the HV and scanning stuff is working though,
good chance it is the tuner. The coil in my TV was inside a shielded
section of the PCB so visual inspection without disassembling it would not
have found it.

Good luck
