Hello everyone!
I've recently acquired an IBM 8514 (The CRT, not the display adapter) and upon powering it on, I heard internal arcing for a second, and then nothing. I opened it to look for the culprit and believe I found it: capacitors in the power supply had leaked on top of diodes, which were heavily damaged. Replacing the capacitors is easy, but I need help finding the correct type of diode to replace the damaged models. I want to ensure I replace these parts with the correct equivalents so I don't damage anything.
Due to the display adapter sharing the same model name, finding information on this monitor online is difficult at best, and I've been unable to locate schematics or a service manual with parts listings. The two damaged diodes (D848, D847) appear to read "01 7N" on both, but I'm unable to find much useful information beyond that. If anyone know which diodes should be used in this power supply, please let me know so I can replace them. Thank you!
