Ahoy folks,

finishing up a complete resto-mod on a Gorgar.
The IPDB.org is down. My printed schemmy does not have enough detail to make out transistor numbers.

The problem is the controlled lamp for number "4" and "target 4" are not working.
I have power to the lamps and the bulbs are good. I suspect the a lamp driver tranny or predriver is bad.
I can't see enough detail on my copied schemmy. Does anyone have a real schematic or a better copy that could tell me the associated transistors? Row 4, column 4. Row 8, column 4. if that helps.

Thanks,

Milton

Thanks for the reply. All new machine pin sockets. What is the column drive tranny?
There is power at the sockets. Leads my to believe it's a drive issue. When Ipdb comes back I'll look at the schematic in detail. Can't be too tough. Everything else is working.

Ipdb down due to hurricane?

Ahoy frunch,

I did check all diodes. They are the freaking glass ones. Hate those.
It has to be something stupid. I'm moving the machine to a better lit area next week.
Possibly a cold solder joint on the feed for "4". Sockets are fine. New. (checked anyway).

I'll post the answer next week.

Yes, it was a trash to treasure resto-mod
