Hmm you might well be right, I just don't know because information about this monitor is unobtainable and it only has 4 boards with in it, the Invertor board, the T-Conn, the button board and the 4 port LVDS board and the only board that I have been able to locate is the T-Conn. The Invertor is working as I see the lighting taking effect and can control the level of it and therefore the button board must be working for that to happen so that only leaves the 4 port LVDS one, so is the scaler board part of that board? In your opinion, could that board be the reason why I'm not getting any video displayed and not the T-Conn as previously was thought to be the faulty item?
