On prior thread, I checked out all the power brick voltages and they are fine.
Looks like the voltages on the PCM board are fine.
Looks like the voltages on the sound board are fine, but a couple register 1/2 what they should. I seem to remember from working on these that I need to go +22 to -22 to see the 22 volts? Regardless, all test loops are showing something, either correct or 1/2 correct.
I got no sound. I got an bunch of weird stuff on screen, nothing discernable, but is different depending on whether in test or play mode. So some sort of image signal is going to the screen. Coin solinoid activates.
No 1/2 player lights are lit.
Looking for some direction and guidance.
1. I am going to put in a new monitor, either the new ones from 2-bit or an LCD. Any suggestions or comments are welcome.
2. Should I pretty much just pop in new/fixed board and monitor? Or is there something else I should try before declaring the board bad.
Thanks in advance. I want to make sure I can get it workign before I put money in the cosmetics.
