Multiple issues after red wine damage partially working but need help.
O.k Here goes, my macbook has really been through the wars after getting red wine spilt on it.
I have personally given it an alchohol bath and clean the whole board top to bottom. it's supposedley also had a reflow as I took it to a guy who did them and I also did the 'oven trick' several times.
If I press the power button the two fans spin up for less that a second and nothing happens.
However, If i place my finger on top of 2 resistors (circled in the pic) I am able to get it to start, it will then happily stay on and work as normal, unless it goes into sleep mode, if this happens for more than a minute or so I have to place my finger on the resistor again to make it start.
This is my first issue. The guy that did the reflow mentioned something about it not having a decent 'g3 on' signal? and that it was unstable or something? I am pretty sure that some component has failed here and would really like someone capable of board level repairs to take a look..
The second issue has recently developed. The built in display started to turn itself on and off, while i had a 2nd display plugged in, and the mac would switch desktops between both displays as if I had unplugged the 2nd display, this gradually evolved into the internal display not working at all.
Right now I can only use the external display although at the second of boot time The internal display does flash on for a moment as do the keyboard lights. Now when the machine is running I have NO trackpad, No Internal Keyboard and NO internal display.
Ok, so here'e another strange thing.
I found that if I hold my finger on the power button whilst connecting the internal battery and let go the machine then starts up with fans at full speed and boots up, like this the internal display works just fine no problems although still no keyboard/trackpad.
I realise that this all sounds far fetched, but I don't know exactly what I am doing, I know a fair bit about electronics but I am clearly not a mac expert. pretty happy that I at least got some life out of the thing that was previously thought completley dead. I really cannot afford a logic board right now and I hope that there may be someone out there that could nurse her back to life?
many thanks for any assistance I may receive.
