I have a sammy 940BW 19" monitor with a white screen, did a visual and on the video board a component has blown, its designated Q400, unfortunately its totally white so unreadable, anyone had the same problem and managed to identify the component or a schematic would be very usefull, i have also checked the lcd board and a smd ceramic cap seems to have been stressed because its got black scorch marks on the pcb lands.
Any pointers appreciated.
