Set came in and would shutdown after 2 sec. I replaced
caps off flyback (c513, c514, c515, c516). I also
replaced c518 (33uf 50v). Tv worked ok all day. Next
day, it's shutting down again. I went trough all caps
in power supply and flyback secondaries for ESR all
check ok. All Power supply and flyback secondary
voltages normal. Even high voltage is ok (27kv)
schematic says should be 27k-29kv. There is a pin
marked fbp on the video IC. I'm assuming that's the
X-ray protection, but all resistors and diodes
associated with this circuit check good. Does any one
have a clue as to why this set is still shutting down?
