[ukvac] TECH: XEVIOUS help!!!
Please help me!
I've a Xevious boardset, but it doesn't work well.
Background is completely black, I can see only my ship and enemy ships.
I can fire and play.

I'm sure that:

-The problem is on the video board (I tested it with another set)
-All chips on socket (some custom, eproms and some rams) work well (i
substitute them with a working set)

Do you have an idea?

Thanks!!

Check the sockets... Prolly not *such* a good idea, but give the board a
little 'flex' (depending on whether the condition of the board looks like
it'll be able to stand it or not, use your judgment...) if you see the
background flicker back in, then count your lucky stars its only a broken
socket or track. If its a logic chip then you're going to have to
troubleshoot it properly, which I can't help with cos I don't own the board.
If you don't know how to troubleshoot, then find out... Don't just jump in
at the deep end expecting luck to be your guide. It IS mostly common sense,
but a little knowledge goes a lonnnnnng way )
