need help to bring my Virus kb back to life

[bieke]

OK, so i have a mint looking Virus kb, but haven't used it in the past 5 years
worked fine the last time I used it
so I wanted to start using it again
and when I swith it on, I just get the display backlit, nothing is shown on the display

I swapped the internal battery
I checked the PSU with a voltmeter, it is still working fine
what can I do
there is a faint whiny sound, barely audible, coming from within

what else can I do
start soldering caps on the MB or what ?


thanks already for helping me
