Hi Guys,
Was hoping for some pointers. I have a WPC No Good Gofers machine. I turned it on the other day and the screen *mostly* worked. It's like everything around the top left of the screen was either not working or flickery. Over the course of a minute this spread from the top left all the way to the bottom and now the screen displays nothing. I've tested the screen in another machine and I know it works fine. I've discovered that i'm missing +60 from the a/v board. All the other voltages are fine I'm fairly confident that the problem wasnt a fuse as they have all tested ok, and i expect that whatever died, did so over the course about one minute. Now my question: What are the most likely culprits? I've run my multimeter over the back of it, the traces, resistors and diodes seem fine (well the ones that look like they have something to do with +60 on the schematic). I'm thinking its one of the Transistors at Q2 or Q1 - is this a good place to start? Could it be also be a capacitor causing the problem? Which ones would would be most likely?
Cheers guys
