Hi folks. I have a High Speed that i just got and it appears that it has not run in awhile. It was stored and i would assume not in the best condition/location. It was filthy so I cleaned it all up and stripped playfield and cleaned, put new lights and new rubbers. Yes all before i even turned it on lol... Why not have it all ready to go when you hit the on button to start playing.. lol. So I got it all ready and the moment arrived new battery's in stalled so i was ready to go. Turned it on got the adjustment failure reboot and got the factory settings and coined it up and well there all good to go. i let it run for about 10 mins checked out some switches and lights. I needed to get the 1683 bulb for the becon so game off and head to auto parts store to get bulb. I come back install bulb and turn on machine and I got only playfield lights. No CPU boot at all. It will play one test sound when i push top test button but thats it. No led number at all displayed on cpu. I tested the J17 connector and re flowed the connector pin i get the 5 volts on the gray wires and I get -12V and +12 on the other 2 wires wht/gry and white blk. Also i test the CPU at test points and Im getting 5V and 12 unregulated. The CPU looked awesome with no battery leakage at all or hacks, all good. I did notice the C30 cap was blown so i replaced that. I am kinda stumped on this, frustrating to have it start up and then walk away and nothing. I figured someone here can get it going with me. Thanks

Update. Fingers crossed it looks like it was the 6802 chip.
