White noise sounds like a bad pokey...

Can't say why free play would affect deflection, but start with replacing
the right pokey and go from there.

Hi All,

a friend of mihe has a tempest. Everything seems to run in the right way,
test passed, board in good condition; but pcb has 2 problems:

1)in attract mode there is a strong white noise. During the game and during
tests is ok.

2) setting FREE PLAY video is reduced to a horizontal line (no vertical
deflection).

Any idea?

Thank you,

vernimark
