Sony Trinitron kv-1201 issue
 

This tv worked fine for a while and then one day it just stopped. Now it only shows this line. I replaced a bad capacitor but it still does this. Any Ideas?

You have lost horz deflection. It is almost always a bad cap in series
with horz winding of the yoke. Its a special non polarized electrolytic
& a wrong sub will quickly fail.
If you order a manual there are at least 2 versions of this set.
You need model, chassis & serial numbers to get the right one.

LFOD !

What's more amazing is that the SCR didn't short and take the power supply with it.

Check all connections and solder joints. If that sounds like a pain, it is. But good chance it's simply a loose connection.

You can always try the caveman method.

Could also be a broken wire or bad connection to the horizontal coils of the yoke. The KV-1201 didn't have the SG613's the blew. Those came along about '74 '75 models.
