    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.
     
  2. 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.
    A service manual is available for AU$22:

    Otherwise you could rent one from High Country:
