OSD works and the auto-prgrammimng locks in channels but you can see what the
picture is. It's a white screen with a hash pattern in it looks like the AFT
won't lock in.
I've replaced the tuner twice, the LA7674, the micro, saw filter, the video
IF buffer and amp transistors, delay line and a few other mentioned components
in the database.
The AFT out on pin 47 of IC200 is 4.5 volts while the SAMS (3547) says it's
supposed to be 0.1 volt. Pin 8 & 9 of the same IC states it should be 0.8 volts
on both pins and they read 4.5 to 5 volts. Anybody had this or have any
idea's?
