I have a Sharp 25A-M100 television, and it has a problem with the vertical diflection circuit. When you turn the tv on, it starts up fine, but the vertical diflection flickers in and out. I Checked the wires to the coils on the tube, but they are fine. The odd thing is that if I am looking in the back of teh tv, and I lift up the left corner of the PCB, the picture comes back and the vertical deflection becomes stable. Has anyone ever experienced something like this, or have any advise on how to fix it?
EDIT:
I was talking with the repair man at the local record shop and he tells me that around the time the tv was made (1992) , the construction methods of the PCBs left many of the chips with bad solder joints, so it may be a matter of adding some more solder to the pins of the vertical deflection IC.
