Hey guys-
My Galaga has this strange little glitch happening that I'm thinking is coming from one of the chips on the board (might need a re-seat?) rather than the monitor. It's flickering horizontal lines that pop up for a second or two and only seem to branch off from the player ship (explosion/death mainly), shots fired (good and bad guys), and sometimes the aliens themselves. On-screen text & background scrolling stars have no issues.
They seem to appear more on the left sides of the things noted above, but sometimes a little on the right, here & there. But mostly extending left. Also, it seems to get worse the longer the game is on.
I'm guessing this is chip-based, as the explosions/bullets/player ship/aliens are probably generated on a chip different than the background/text?
Can someone tell me which chip to re-seat, or should I just reseat them all? Checking the voltage & re-seating the chips were going to be my first order of business, but does anyone have any other suggestions or have seen this before? Pics attached, sorry they're a tad blurry, I extracted them from video...
