I recently aquired a complete IBM PC AT 5170 w/ 5154 Monitor and IBM AT Keyboard in a lot. I knew that the monitor needed repair as the seller told me when he was testing out the monitor it "released its magic smoke". Anyways I was hoping a few caps would be enough to revive the beast so I picked it up. I really should have done this myself but I've never worked on a monitor PSU before and everyone told me that I could kill myself working on it. So I took it to a repair shop.
The owner has had it for a month now and has been slowly working on it, hes not familiar with this old of a CRT so I've been trying to field questions for him to help out. He's pulled and tested a few parts and replaced all the caps but he's not sure what value the resistors should be or what capacity a certain component should be. Does anyone have a schematic for the PSU of a 5154? If not perhaps someone who has one with easy access might take a look and tell me what the values of the following items are:
R37 Two resistors blown, can't tell from the resistors what the values are.
C6, what is the value for this capacitor? He's guessing 250v?
I'm posting pictures below of the board, and the resistors, and maybe someone can help, thanks!
Thanks guys, I wish I was ready to work on monitors but in the pursuit of safety I decided to let someone else handle it, but I could still use your help.
