Greetings,
I have this monitor wiht a smashed screen and I would like only to understand which problem had only for curiosity.
Opening it I found its very similar or maybe identical in power board and main board to the ASUS VW224T I repaired some days ago for a bad capacitor on the power board.
The problem: Fuse : Gone, Bridge rectifier : Gone and a strange spot circular burn on the screen panel side in corrispondence of one leg of the transformer (near the R926 Resistor).
I replaced bridge , fuse but still non life but no short circuit now.
320V in the big cap after bridge (ok) but no alternate voltage on the secondary legs of the transformer.
No visual damages, but I suspect an open resistor 1R5 value near the burnt and maybe the IC gone (??).
I m mainly curious about this circular spot, any ideas.
Regards
