before i get rid of the link to the pic i took of the cocktail might as well post here,i have seen other similar threads and i understand where the problem might lie,just wanted to see what experts might have to say.
i have reset line prob,voltage way too high so its gnd'd.i capped the ps and rep[laced a regulator to no avail,its at 2.5v.
i replaced the crystal on this board as it was missing and i put a cpu chip which was missing also as i had a board here already with garbage onscreen so i salvaged parts from it.
the original i had here i went and changed h socket with a 28pin one and the test rom was not running right,so i went and bought a faulty one from usa that had the roms and sockets etc on.i run the test rom on it and it does nothing bar give me the thick lines,the test rom wont run,i checked strapping and s2 is gnd'd which if i am correct is right for 2716.
just want to see what experts have to say as i know invaders is real pain in ass board with probs,but,what i get now is big improvement over what i had with the old board i originaly had.
cheers guys/gals.
