Acer Monitor X233H b.

[T Marshall]

Hi
Can anyone help with schematics of power board for above Monitor.
I have got schematics for X233H but this X233H b is completely different.
Uses a TL494 IC.

The problem is,the two fluorescents only briefly light twice.

Many thanks

I would be looking more at the inverter or maybe one of the
fluorescent's being bad than the PSU unless you've verified
the PSU is bonked somehow.

thanks for reply. Its the inverter and control section I am trying to
check. Every thing else seems to be ok. It did fire up once and display
picture OK. looking for circuit to see if I can inhibit error detection
