    e-studio 230/280 power supply repair

    Hi all,
    i've got 2 faulty power supply boards that i'd like to repair, there both from machines that had the fuser lamp wire trapped after servicing and subsequently blew the psu.
    Ive replaced the 10a fuse on the board but the machine only powers up for a few seconds then switchs off by itself..... a new psu solved the problem but i'd like to repair the old boards if possible.
    I've heard this is a common problem and that theres an easy fix???
    any ideas?
    Cheers
    Simon

    Replace all triacs.
    A tree is known by its fruit, a man by his deeds. A good deed is never lost, he who sows courtesy, reaps friendship, and he who plants kindness gathers love.
    Blessed are they who can laugh at themselves, for they shall never cease to be amused.
