Yesterday ive bought my first pin #dungeons an dragons. U2 was missing and the game was untested. Since this is my first pin i need some help figuring some stuff out.

It still has the original mylar but it has air bubbles.
10 targets are missing
No topper.
Most parts have a little rust.
New mpu
New glass
All the plastics in a box
And new rubbers

After testing voltages and replacing a fuze, a friend of mine made the missing u2 chip and we put it in. We also noticed after a while u3 had a misplaced leg. Now i have lights but none of the hv stuff works. No coils no screen ( we sometimes do see a dot appear). The audio board connector started smoking aswell. So we unplugged that for the time being. So what should we do next ?

Thanks il try that. And i dont think its a big problem that is holding us back since all the voltages seem fine. So it will be back from the dead in no time. We think it might be a u2 an u3 syncing problem.

Thanks and after the game shows a bit more life. Il order some novise and 8 brand new balls and a bunch of other stuff. Im cleaning one now in acid just to test some stuff out with out throwing rust everywhere :p

The last owner bought it broken hes had it for a coupple of years but never had the time to fix it. He had multigame fix the mpu but he broke the legs of u2. Looking at the state of the rock hard rubbers id say atleast 15 years with out some love.

UPDATE : the mpu does not flash at all. I thibknit does get power since ive had some gameplay bulbs on at some point ( u3 had a leg sticking out at the time ) is this bad ?

my tp 5 (+14) and i think my tp1 (5v) are not there. we blew a fuse because we did something wrong ... il check tomorrow again. so we think its the 20v 11000 uf cap that is broken it does not seem to store allot of electricity .

After cleaning all the fuse holders it booted cant coin-up and the audio board started smoking thebfirst day.so we yave to check that. But we are close to a running game il post a photo tomorrow. What should i check now ?

when the game boots it says "dragon lair LT". i think its an error code.

update : it was. left lair switch was stuck. still cant coin-up. i dont seem to get more errors.
im so close to a playing game just dont know what to do next.

Thats what im thinking aswell.( forgot to post that srry) but knowing that im not the only one who thinks this fixes it helps

I dont have a key pad in trying to borrow one from my local pin repair guy. He also repairs my arcade tubes. But he diddent pick up yesterday. I hope he does today. I think il buy an anypin nv ram chip so this never happens again. I can make the pad my self but it takes a while.
