Sunny,
First check and see if you have the VCC voltage on the chip, if not check
for a open resistor off of the flyback. If you have the voltage, I would
change C451(220m-16v) and put in a new chip again. Failing to change C455
and C451, when changing IC451, can result in the IC failing at turn on.
(Been there, done that!)
