I have a small Sony TV model FDT-5BX5 which has a horizontal shift issue.
Horizontal Shift on a Sony FDT-5BX5
I have located potentiometers for the h-size, v-size, pin amp and pin phase, but there is no v-pos or h-pos. (at least nothing labeled as such)
I understand that sometimes h-pos is also handled sometimes by a switch or a jumper, but I can't find that either.
Can anyone help me to identify the faulty component, or something I can adjust to fix the issue?
There is what I would describe as a loud whine that I think is coming from a transformer on the power stage board. There is a pot marked "RV-601" which appears to be close to this small transformer. I didn't want to adjust it without knowing what it would do, but here's a couple pics. I have pics of all the boards if required for me to post.
Any help that can be offered is appreciated!
