fdt-5bx5 Violently Exploding Capacitor

1) Ok, diodes and caps are checked.

2) No difference between horizontal size and horizontal width in English. That's why I think the purpose of the transistor Q380 is a bad translation and has nothing to do with the horizontal sweep but probably the horizontal blanking pulse width.

3) L503 -- I meant shorting, not shortening, in other words, temporarily connecting a plain wire across the terminals of L503. HOWEVER, NOW THAT I SEE ITS SIZE, I WOULD NOT DO THAT AS THAT MAY ALLOW TOO MUCH HORIZONTAL SWEEP CURRENT AND INCREASE THE PULSE VOLTAGE BEYOND SAFE COMPONENT LIMITS IF YOU DO THAT. BETTER TO SEE IF YOU CAN FIND A REPLACEMENT.

The only source I know of for magnetic core inductors is a custom shop that will wind them for you, but they cost way more than the TV would ever be worth.

Not to mention that I guess at this point I can't even be sure that the coil is at fault. I'm just guess about it losing it's magnetism. In all other ways, the coil appears to be fine from the outside, so other than demagnetizing over time (which I don't even know if that could happen), I don't really have much to go on with it.

If you know of some way I could cheaply buy a replacement (ideally something adjustable) that I could try out, that would be great.

Or if there's any other obvious things to try of course.
