Hi people, got the psu out of this rather large CRT set sitting
infrount of me here, (rest is out in my shed in bits.) I need help on
tracking down IC902 might be, as it has had the frount blown off the
chip leaving no markings. It is a 9 pin device sharing a big heatsink
with the bridge rectifier.
I probably also try to find out what made it go bang, it did have a
small slater crawling around in it when first pulled apart but no sign
ofany of its toasted brothers, fuse is intact, filter cap is staying
fully charged.
Any help would be appreciated, its an older set now but I think screen
size may save it from scrap if nothing else (80cm)
Joe. |

Rectifier is probably a Schottky. IC is a switch of some sort. Make, model
etc for TV set? |

My memory is very poor, but could it be a TDA4601 regulator?

Replace all the small electrolytic caps on the primary side of the
supply.
