I get it! It turns into a picture of Johnny Rodriguez!

I'd say don't power up without them. Heat and sensitive electronics don't go well together. If the board was engineered to require a heat sink, a heat sink it should have. Remember, an ounce of prevention... -cloggedmind

Heh. Do I want it? DID I?!! But seriously, Check D21-24. I'd also suspect Q21 could be heat damaged/shorted. Did the fuse go when you powered it up? Replace caps C21-22 for sure (if you haven't) and c23 for good measure. Gottlieb power supplies suck. bad.

Q-bert still not working, eh? That'll teach you to outbid me! Seriously, did you replace everything on that Q-bert power board? To make it live again you will need to completely rebuild it. Iirc that particular machine had a seriously cooked sound board connector, too. Did you replace the...

For all those who were desperate to find an answer to my question above, I have the solution: 2 days, four hours, several books from the library and a refresher course in Japanese later, I have concluded that the voltage drop test is not sufficient, nor accurate in this case (what a surprise)...

My Hang-On sound board has died. Slowly and by degrees. First the motorcycle sounds died and then, after a few uses, the music and other sounds. There was some intermittent buzzing at power on and then-- silence. All other functions of the game are normal. The power on the board is ok, and the...

There are some lo-rez scans of schematics at CrazyKong: http://www.crazykong.com/manuals/ ----Edit--- I have just shipped out a full pdf file of the manual to CrazyKong. I assume it will be posted soon. ----End of Edit--- As far as the steering goes, you have to remove the handlebar cover...
