Mitac LC-552 LCD Monitor

Hi,
newbie to the forum - was wondering if anyone would have a schematic to a Mitac LC552 lcd monitor. The unit powers up with led flashing between green and amber. I suspect it to be a power supply problem but am unsure without a schematic. Anyone able to help - would appreciate any pointers or even better the schematic.

Fanx in advance

Another dead one here. In case it helps, mine has C3 duff on inverter board (.22uF 160V unknown type, grey rectangular, epoxy encapsulated) bulging + reads as 1KOhm at low voltage, (C4 is identical capacitor and OK). Fuse F1 open also (middle of inverter board, next to connector).

Not exactly a professional (+ got dirt cheap from car boot sale), so I'm just going to replace those 2 components and hope.

Anyone with a schematic or parts list for the inverter board would be a great help. Inverter itself is a Delta DAC-12B058.

Good luck

yep can occur if you open the screen to wide,,small poor built jumper plug creates bad connection causing power drain also screen is mega black ,basically it design fault ,wire is to short,or perfect if you want to sell more units,,if you catch it before any real damage has been done you can splay the pins to make greater contact ,hey presto just saved a few quid
