Got an Asteroids Cabaret to restore. It was bought working all except for the ship shots did not always fire in a round ball. After 2 games at home and the on/off switch breaking in my hands, I decided to restore it then.
Things I did:
Installed the Bob Roberts PCB cap kit.
HV/Reg cap kit.
Monitor/deflector cap/transistor kit.
Replaced the two large caps on the deflection board.
Did not do the deflection resistor delete mod, with wire. My board does not have these two resistors.
Re-flowed solder to all male header pins on all boards.
Checked for cracked/questionable solder joints.
Replaced Big Blue.
Replaced all fuses.
Replaced the on/off switch.
Put in a new crystal for good measure.
PCB connector edge was cleaned, looked pretty good compared to others, so I left it alone. (again, the machine did work)
Replaced 3 crappy Scanbe sockets and re-seated all chips. I know about Scanbe from bringing pinball machines back from the dead and clays guides!
Replaced power cord.
Double checked my work, did not destroy any traces or pads.
Thought I was good to go, so I turned the machine on!
Nothing cracked or poped, no fuses blew. All I get is P1 and P2, steady lit, monitor neck glows (looks good to me), PCB LED ON, Spot Killer LED ON, speaker has slight pop when I turn the machine on, and the monitor has one small dot in the lower left corner. Sometimes the dot moves to the upper right corner.
Searching the Asteroids repair manual on line, all it said for this condition was clean PCB edge and check for loose connection. I did that tonight and no change. I also read that monitor will not display anything until it see's a signal. I searched this site too and nothing like my condition.
Tonight I also removed three chips with dirty legs and cleaned them, I think all were ROM chips. No change still! I also looked closely at the PCB connector and replaced one of the terminals that looked weak and barely touching.
Game will not go into test mode. I flip the switch and nothing happens.
This is how I roll, when I restore a game, I do it all, I do not want to visit 30 year old parts continuiously...
Thanks for the help!
