Multiple components fell off my card when cleaning and recapping. Is there a possibility of bypassing this card and have the computer power on without the button?
Fixed update:
I went on a wild goose chase and it paid off. Traced the pot on the underside of the board testing all resistors. This little dude measured 9Mohms. That can’t be right. Found a reference guide online (which can be wrong btw) that said it should be 1k ohms. Used the rework...
Re-glued the inductor back together, reinstalled and same issue (I didn't expect anything different). PP1 isn't easy to get to so I'd rather set it using a MM once someone is able to provide a solid reading.
This may or may not be associated but I noticed this inductor (located at LL2) came off it's glue/base and was very wiggly, it is somewhat close the yoke connector but I have no idea what it is. I'd figure replacing it couldn't hurt but I don't know what it is or what the 95 represents. My...
Removed the pot for centering horizontally, it measured appropriately out of circuit. Could a load affect the pot? What components control horiz that I can test?
Hello, I recently performed an unsuccessful recap on the analog board, when I powered on RL54 started to smoke so I turned everything off. Recently I re-checked ESR on all caps, triple checked polarity, replaced the 30 ohm 4w resistor on RL54 (there is some confusion here as the fried resistor I...
Well, I tried the 330ohm, and it also smoked so I turned it off. I think now I will try to disconnect as many things as I can and add them one at a time. I do have a AV board for a performa 579 so I can poach some parts but because it was a bigger screen a lot of items will not transfer. I'm...
Hi, I see RL54 as 30ohm 1w on https://powercc.org/640x480/ otherwise it's listed as 330ohm as stated above. I'm looking to figure out my issue listed here:
any thoughts?
I found one doc that said RL54 should be a 33ohm resistor: https://powercc.org/640x480/
a few others state 330ohm, can someone give me a definitive value?
Based on the color code of the original I see it as a 33ohm, I’m not a pro at reading color codes btw. Also will a cooked resistor measure...
Hi everyone, I did the painstaking analog video recap on my color classic verified polarity multiple times and thought I was in good shape because the computer booted up without any issues. Today I booted the Mac again and got a bouncy pin cushion shaped image that looked like it was shifted to...
