Out put transistor t2190 short again and again tv circuit board


I know most of the time if the flyback goes bad it usually takes out the horizontal output transistor with it. Replace the flyback and the HOT and test the surrounding components.

You are in shutdown protect mode, it may be due to a bad flyback transformer and horizontal output transistor, replace both if one is found bad. RCA is nortorious for flyback High Voltage transformer failure.

I need to find a service manual for an RCA F32650 so I can replace a blown flyback transformer, preferabley free if possible


I have repaired many of these; if a high pitched buzz when you plug the set in---flyback and horz. output transistor are bad--transistor has a generic number on it--Flyback is location number LL05, part number should be 257805---you will find RCA no longer has this part--most now are replaced with an asti #2078----CHECK the RCA number on Ebay---company I get them from is Suburban Electronics---Flyback and transistor are less then 30 dollars for both.

I was told tthat the flyback is bad on my toshiba tv model #CF36G40 can i replace the flyback myself? Is there any adjustments that need to be made after replacement?


Stay the hell away from a flyback. It will knock you clear across the room! The only thing I look for in a tv is an internal fuse, and then I look very carefully. If I don't find a fuse, I toss it.

0 volts on pin 9 of the flyback


Base on the service manual information, yes IC561 could be defective.
You did not get the +15 volts because the TV failed to power up and the majority of voltages are coming from the flyback transformer.

Usually the horizontal output does become shorted when the flyback goes. I would replace the H output as it only cost around 3 dollars. You can check it with an ohms meter out of circuit to determine if it is indeed shorted or open.

FLYBACK Transformer for APex 32'' Model #PF3230 Flat Part #BSC 70Y


Its not worth the repair if you still want to go ahead i need to know two things:
Are you going to have a qualified electronics technician fit it?
If you are planning to fit it yourself are you a qualified electronics technician?
If you answered no to both of these questions i cannot tell you where to get one or how to fit it due to the massive amounts of danger involved.
