Hi Zaheedi,

If the output voltages from the power supply is good and tested good even with 100 watt bulb along the B+ line then probably not due to this IC.

HI Zaheedi,

After you have connected the 100 watt bulb and got back all the right voltages and did not shutdown this means it could be the something shorted in the high voltage side that had causes the power problem. It could be bad flyback, horizontal yoke, shorted diode and etc.

HI Oging,

It can be due to power supply itself have problem or something shorted/leaky in the secondary side. You may need to visit the link below to isolate the problem:
