SONY KV-32S40 32" Trinitron screen distortion bowtie
The bottom half of my screen intermittently shrinks like a bowtie and
sometimes the picture would just disappear. Giving the TV a good smack fixes it. Then, after the TV warms up, the problem no longer intermittently appears. I resoldered a bunch of connections. Now, when I turn the TV on, I get the degauss sound and the power light blinks like it normally does during warm up, but the picture never comes on. When I was resoldering, I found a spot that looked like sony spilled some solder and may have shorted two connections on the mainboard. I cleaned that solder off. Could that have been an intentional solder connection on this TV model? Also, I pulled on that thick red wire that goes from this transformer thing on the main board directly to the picture tube. I then realized it wasn't supposed to come out of the transformer thing.
