Find a horizontal output transistor or flyback

Shorted horizontal output transistor. Might have to call a service technician, normal parts and labor charge $100-125.

The fly-back transformer and horizontal output transistor is probably bad check Matt Electronics for the parts. the fly is about $25.00

Looks like the projection is fried. I'm afraid you would have to exchange for new one if you can or purchase new Tube.

There is a little loose sleeve at the transformer. It can be pulled out, but it is best to squeeze the sides through hole on each side of the terminal to remove the sleeve. The wire just comes out with a small pull afetr the sleeve is removed. Good luck.

Absolutely right about the transistor and also check any adjacent resistors to the transformer and to the line output transistor. Good luck.

Maybe the flyback transformer are damaged also the horizontal output transistor.

You can get one from Here

I would only use the original part. This site I gave you is for the original Horizontal output transistor. If the part goes bad again, or runs hot, the capacitors in the circuit or the flyback is bad. Good Luck

Heres the fix for your set, replace the following 2 parts:

1) flyback transformer RCA part number 257805
2) horizontal output transistor RCA part number 237470
you must be proficient at soldering & un-soldering or you can`t replace these yourself, be advised that the anode lead coming from the top of the flyback transformer can carry a VERY NASTY shock if not discharged properly before trying to remove it from the picture tube, I`d strongly advise you to call a tech unless your familiar with this type of repair, BMW Rider

sound like u have a bad flyback xformer also u need to replease horizontal output xsistor

If you can find the horizontal output transistor which is located near the flyback transformer,one lead of this drive transformer is connected to the base lead. (horizontal output transistor). There may be a little coil in series with this lead going to the transistor.
