Hi Daz,

  Only link noticed for odd video problems on that model is to replace the TCON board.

  Never had one - yet - Chris.

  Is 'TCON'  board 'Screen drive' - simplicity is us.

hi chris+sparky
thanks for the reply
yep, checked all fuses and the fault isnt intermittent or thermal
and  the tcon + video + lvds pcb are all the same thing(i think), the board the screen plugs into.
any other ideas?
many thanks
