Part number is 198794. Don't sub because it won't work. I agree though.
This transistor does not short without a cause. These are a complex set
to fix. I assume it's shorted center lead (collector) to one on the
other 2 leads? It's normal to measure a short between the 2 outer leads
E-B in circuit, and out of circuit normal to read about 25 ohms.

Your local service shop that does RCA/GE repair may be of assistance,

probably charge full list price for it though. Maybe you can shop on
line,
"Google", for the item or see if E-Bay can supply a working 9" at
modest
charge?
BTW what caused that transistor to blow out, is the LOPT ok?? May
want to
check out the associated components also, including, do you have
drive to
the output and proper bias voltages.

Hello Everyone

I am trying to repair an RCA 9" Color TV #E09344 (5/2002)

I need to find a replacement Horz Output Transistor # ST1803DHI
Where would be the best place to get one? Most places have a min
order
price
and I only need 1 part.

Thank you,
Jeff
