    suyama mj7cna screen goes blank

    Hello, I'd like some suggerstions please.
    The above monitor obviously has a hardware problem. When connected to a desktop, the power light is on green (indicating a signal is being received). A dim screen display will appear perfectly rendered for less than a second and then goes completely blank. If the unit is then turned off at the power and on again after a few seconds the display will again appear briefly.
    I have connected the screen to 2 different PCs and the same fault is in evidence.
    I am reluctant to put it in for recycling and buy a new one when it seems most of the unit is working fine.
    Suggestions please?
    Thanks Chris

    From the description,the problem is certainly on the PSU/Inverter Board PROVIDED that the Lamps themselves are ok.Your first task is to open the unit,take some photos and attach,using the manage attachments section under 'Go Advanced' below.
    You may well spot bulging capacitors as soon as you inspect the board.

      I have dealt with a few of these and as long as the lamps are ok
      i usually find that a full cap replacement sorts them out ,
      the caps may well look ok but are low quality .
      Also i would resolder the transformers too .
      But as Rtech said open it up and post pics in case yours is using a different type of psu
