Well... I accidentally snapped that nipple bit of CRT, sounded like it released gas.

I heated up the ROM hi, lo and the SWM chips on the board, still didn't chime but the checkerboard garble changed a bit, the lines were also in different spots and were flickering. Knocking the case doesn't do anything anymore, I guess the joints are stable now, ill still replace all of them...

I only did about 5 of the joints, Ill find some time to swap out all of the analog board caps and see if my university has anything to help me resolder every joint on it. Also the 5V was tested from off to on, quickly reached 5.12V and didnt move for the 30 secs tested.

Unfortunately the checkerboard hasn't gone away after 2 days.

Wont boot, Ill probably put an intel nuc inside there.

So my iMac G4 cant produce 5V, so a 5V power supply is hooked up to the molex connector of my iMac through the dvd drive hole, you can see the logic board through the holes on top of the dome because both drives are removed and a red light comes on when the 5V supply is turned on. Removed the...

I replaced the old solder joints with new solder in all the analog board to logic board and CRT connectors, molex on analog board and other places, replaced 3 caps and removed RAM jumper. I have to wait for it to boot normally as its in that checkerboard phase right now, hopefully it will boot...

Yes, i tried putting a blob of solder on points 1 to 4 of power connector and points 1 and 3 and 2 and 4, still nothing, 5V appears to be an issue, apple service manual says to replace the logic board but I want to fix it, next i will try and run 5V 1a through the molex with an adjustable power...

I forgot to say, the mac boots into desktop just fine and stays that way, some times it doesn't chime and come up with a checkerboard pattern. Here are some pictures of when I first got it, when half of the case colour was restored, my bad looking cap replacement (before new ram) and the...

I double checked to see if I uploaded upside down pictures, the original files weren't upside down, I wonder why they came out that way.

All three have new saft brand PRAM batteries, Macintosh SE has a new 4MB samsung ram kit, new caps on logic board, I have every new cap for analog board including the panasonic 3.9uf but haven't put them in yet, all rom chips were reseated and cleaned with isopropyl alcohol, the board is the...
