If you can identify the value you should be able to replace it and get the Gf3 working again...
I sold a Gf2 to a freind and it packed up after four weeks!
[embarisment or what?] it was fine when I sold it, now it has lines all over the screen, you can
just kinda make out windoz behind the mish~mash. any ideas?. it was'nt OC'ed at the time. it just packed up for no apparent reason!...
