Firstly does anyone have schematics for this model iMac? I can't find anywhere. Does anyone know the diagnostic leds mean on this model. I have the bottom one on, the next one up flashs on button push and the rest don't light up. Imac does not boot. Have gone though board, no liquid damage or...

FUCK!!!! Disregard this sorry. Made a fkn stupid mistake need to open my eyes and plug keyboard connector into keyboard for fuck sake.

Hi Duke.. So I replaced the LCD today on the 2015 12in MacBook. Forgot to plug trackpad to motherboard in. Opened it and did it last however battery was still connected and I made smoke. Trackpad would then get really hot. And there was a burn mark on trackpad motherboard flex cable. Took...

Must of been the ic because I changed as well and there was small corrosion around pin 17 and r7202 had a hole in it. The problem 100% was fixed after doing so anyway

Problem solved. Ppbus_s5_hs_computing_isns line was not being created.

Looking for help here. Works perfect until lid gets closed upon which I guess an smc reset keeps happening. When the lid is closed for a short while you hear the chime and it reboots and either comes back on or stays off. Then power button to get going again. Sometimes I have to do another smc...

Fixed! C7095, replaced and charging and back on!

lol thanks, believe me when I say I am trying!

ok so I measured in ohms on the multimeter, 0.588 pp3v42 is that a correct way to measure? I'm not sure if I have the range set correctly either

Diode mode. Negative on line positive on ground

PP3V42 shows 0.327 L7095 shows 0.327 both sides U7090 is dead then? It was the only water damaged part I could find anyway

I swear to god no matter how hard or how long I've been trying I cannot make sense of bloody schematics. It's drives me crazy. Great with hands fkn dumb dumb in my head. Really really wish I was in the states and could go sit with Louis or Jessa for however bloody long it takes.. Anyway can I...

just need some confirmation that my brain is working correctly here please. U7090 had very minor liquid damaged. Cleaned and still can't get ppbus_g3h. So no light on charger. After repairing u7090 the charger is very dim for a second only. So I tested for shorts on ppbus g3h. Can't find any...

Thanks Louis and Duke, haven't been on here in ages which means somebody is building up his repotoire of knowledge and skill! Anyway am stumped and looking for advice today. Mid 2010 IMac 27in. Backlight is gone however it does randomly come back on for no apparent reason. Then goes off again...

One last go... r5281 is 3.4v r5280 is .5v i don't have a working oscilloscope to know if pins 2 of r5280 and r5281 are doing what they are supposed to do right now either. Changed u7000 r5281 and r5280. Something is fucking up the data lines.

Changed it, no difference. Got ripped. Sending it back.

actually probably try changing u7000 first I reckon

Thanks Duke, I think your right, it does seem so.. I'm going with dead, I tested with two working original batteries. Only had a fan, dc port and battery connected too. Probably best off doing an eBay return at this point. It cost me $675AU!

So here's an update.. ended up repalacing the board that caught fire. Bought a supposedly working board from eBay, Rnrcomputers to be precise. Long story short. This board doesn't work either. Has no green orange light. Took 3 weeks to arrive and really don't have time to send it back and wait...
