paperboy-disco monitor med res, not powering up, help please
I am working on this paperboy for another klover. I got the game basically working aside from this damned monitor.
The screen was wacked when I got the game, bad colors, squished picture, but it did work, somewhat.
I recapped it, reflowed solder, etc, with a kit from Bob Roberts. Now Bob's kit had some different caps than were previously in the chassis, but this didn't worry me because I see this all of the time and it seems that Bob is always right.
In particular there were 2 positions.
C107 I pulled a 1uf 16v NP cap, bob's kit had a 10uf 50v cap
C241 had a 47uf 50v, bob's kit had a 22uf 50v
Anyway, when I pulled the monitor I noticed the degauss coil didn't seem to be connected.
moving forward..........
I put the recapped chassis back in the game and voila, killer pic, everything is awesome, boom. awesome shit.
Then 5 minutes later it just shut off. No blown fuses.
The big white rectangle (thingy) on the front left of the chassis is piping hot.
Once I take it out I notice this time that 1 of the pins where the 4 color wires from the yoke connect to the chassis is broken off, it was soldered into place (barely).
So today, I switch the 10uf 50v cap that bob sent (C107) back to a 1uf16v NP cap, and I replace the broken pin where the yoke connects to the chassis. I did not connect the deguass coil this time.
Anyway,same thing, monitor isn't getting power and that white thing is smoking hot.
I don't know how to measure b+ on this thing is that a possibility, that it's too high?
love some help
