    Grateful for any help with this one....

    I have a fujitsu 4222 plasma that sometimes refuses to start .. once its going
    its fine... but once cold... its touch and go .. the problem is getting
    worse.
    Once it stops working it leaves the red led constantly flashing which I
    believe indicates a PSU problem.
    Spoke to Fujitsu who reckoned either main PSU board ( my theory) at Ł450 or
    either of the two sustain boards Ł900 each and its guess work which one !
    Does anyone have experience of this unit or similar for a component level
    fix ( I am a qualified HV engineer but don't have any plasma experience)

    Really appreciate any help

    nope... its not the processor... definately the switch mode .. you can hear it try and start switching then stop and then the processor shuts it down.. if you heat the transformer. sometimes you can get it to start then its fine.. as long as you dont ever switch off ! price from fujitsu is £450 for a new power board.... 1/3 the price of a decent plasma ...

    Thanks Dilsher

    Gotta admit .. this thing is getting to me now.. I swear the back panel is on velcro! when it works its fantastic.. despite the slightly grey blacks.. but the switcher is noisy as hell and sometimes refuses to start.. Ive repaired all manner of switchers but this one has me foxed .. fixing it has become an obsession even if its to prove you dont have to pay £450 for a new PSU from the manufacturer . So gonna kep looking and will be sure to post if I fix it .. otherwise looking for a 4222 or 4221 with a brokern screen to rob for parts ..

    cheers all

    Mate if this fuji has the same power supply I will be one happy chappy
    I suspect that fujitsu use the same psu module for a couple of years on different models , only updateing processors etc to get the best performance , so there is a good chance its the same board .. I will post a photo if you can get inside it.. its about fifty screws and its under the plastic cover in the centre of the screen .. more than happy to collect of course ( where are you BTW!)
    cheers
