New pin: Lethal Weapon 3 (Update: FIXED)
ChadTower:
Every game I get seems to have component failures when I get it. PIAs, drivers, predrivers, RAM, ROM, etc. :banghead:

Same here.

What can I say? It's the whole "it followed me home can I keep it" syndrome. It's not like I pay a lot for these games so I can't really complain. My project games tend to be good titles that I got really cheap but need a lot of work.

Yesterday I played the machine until it failed so I could poke around some more. game would not boot again after power cycle, which is what I wanted. I flexed every power connection on the game to no avail. I flexed every component in the blanking circuit too. At one point, the PIA light stayed on with power up, but went away the next time.
I decided to let the machine cool back down and see what happened. I came back about 2 hours later and sure enough, the game fired right up. I should also note that the last week I have been playing with the head wide open so I could watch the LED's. Last night I played with the head closed up. It definitely failed sooner.
What's all this mean? It means I highly suspect a cold solder joint on a PIA chip, or merely a bad PIA chip that needs to heat up to intermittently fail. In the meantime, I am going to reflow every PIA pin and see what happens. There are 6 PIA's, and I don't look forward to hunting down the specific error if it is a bad chip.
ChadTower:
If you think it's a PIA, play it to failure, then spray the PIA with cold spray.
