Toshiba with grossly misaligned red gun	Can't Post

Hey all,
Just curious if anyone can figure out what might be wrong with my set by looking at the enclosed pic. The red gun is obviously not matching the other 2 guns as can be seen in the pic. Was working fine one day and the next day (poof) this happened. Not sure even where to start looking. Capacitor, perhaps?

Any suggestions/thoughts?

Toshiba TW40H80.

Thanks. Jim B.

It looks like your red convergance is out. The problem normally is a defective convergence amplifier on the sweep board. There are two of them on a heatsink on that board,change them both. The part# STK-110 or STK-130 are stamped on the part it self. Also look at the resistors next to the output and replace any that are discolord compared to the rest. Take note useing the tv my result in the bad part shorting and causing other issues. Good luck.
