Ok, so I plan to order a switcher from arcade shop with my next paycheck, but I figured why not mess around with the old one until I get the new one...
(See before and after pictures)
After cleaning it up I hooked the board back up, the -5 and -12 LED's were both light however the +5 and +12 were both off...
After a little tinkering I tried it again and the +5 light came on but the +12 was still off, This time all the LED's on the game board came on (1-6) So I broke out my meter and found that the pot at R28 is not working...
Still not getting any sound or video, I assume this is because the +12 is still not working. SO here are the questions..
1. I plan to try to find a pot at radio shack, what should I look for??
2. Where on the power supply will I test the +12 and +5 to see what they are putting out?
3. Is all the lights on the game board being on a good sign?
4. I can here the monitor, however when I power it on and off it does not flash or get lines or anything like most CRT's that I have seen is this normal or should I expect monitor issues further down the road?
5. The test switch (push button) on the game board seems to be stuck and nothing happens with the LED's when I push on it, should I go ahead and replace that too or no?? If so once again what should I look for at radio shack?
I think that's it for now, but I'm sure I will think of more. I really appreciate everyone's help on here, I would be lost without it!!
