TV SONY KV-X2933E CHASSIS AE-1B: No stop scanning channels

[Javier]

Hello friend.
I have a TV Sony KV-X2933E Chassis AE-1B with this problem:
When It is searching channels for tuning, it stop 1 second in every channel found but it continues searching always. I have replaced the tuning control SDA20560-A012 and the memory but it doesn't fix the problem.
Thank you for your help.

it might be worth checking for dry joints on the aft coil in the if stage, on the uk versions of the set the coil suffers from poor connection and causes that exact fault.
