hello i currently have 4 va250d's all exactly same problem switch on but no display.
the board from a fujitsu amilo L7320 fits this va250 the main problem with the swap is the on off switch is in the wrong place, cured this buy simply cutting hole in the top cover and then
simply used araldite glue to replace plastic switch after cutting it from the original L7320 top cover.
the keyboard also has to be changed to allow you to switch on the wifi card. As wifi controlled via keyboard [Ctrl +F2]
so it is possible to carry out repair if you have the know how and patience and of course the parts.
hope this gives hope to a few of you. i also believe the fujitsu siemens Li 1705 motherboard fits but cannot confirm this as have not checked it out myself
regards john
