UPDATE: RCA TV model 14512T Repaired
 

Hi,

I repaired RCA TV model 14F512T with no vertical deflection problem. R409
1ohm was open. IC301 ("TDA4864AJ" on device) is bad, but I couldn't get a
direct replacement (not available). A "substitute", part number 264870
(STV9302A) was sent, is NOT A DIRECT REPLACEMENT. After several
attempts to get the correct part failed, I decided to "configure" the
"substitute", based on info I downloaded on it and the original part.

MODIFICATIONS:

Remove R307 220 ohm.

STV9302A TDA4864A7 (orig.)

PIN 1 goes to PIN 6 hole in PCB
PIN 2 '' PIN 1 hole
PIN 3 '' PIN 2 hole
PIN 6 '' PIN 3 hole

Other pins go to the same number holes in PCB. I used wires on a few pins
because the pins couldn't reach. You may prefer modifying the PCB instead.
