HI Guys
My Viewsonic VX724 monitor died a few weeks ago, following a few hours where it smelt of burning, it now gives the black screen, green on/off button flashes. (im not an electronics bod but i know which end of the soldering iron to hold!)
I have replaced 5 domed caps on the power board, the green board caps look ok. The button still flashes green.
following previous threads and a bit more troubleshooting, there is 12.3v on the connector that joins the 2 boards with power lead connected.
There are two small connectors at top left and top right of power board ( not sure what these do)
unplug both top right connectors screen flashes
unplug both top left connectors screen does not flash
when i connected up the mains just now there was a bit burning smell and smoke coming from power board although i couldnt see which bit as i turned it off quick.
hope there is enough clues here for you to help me
any help gratefully recieved
