Hi all , thanks for having me & I think this has been asked before but my case seems a bit odd.
I have a MacBook Pro , board 820-2915a and it turns on , chimes etc etc , keyboard lights up, fans spins , can turn caps lock on/off but screen is dead.
Iv tried the resets , shine torch through back logo , nothing , it seems the screen has no power. If I plug charger , it charges but if I disconnect battery it displays green light but won't turn on. Iv tried screen on with another board & it works & seems I'm not getting any voltage at pin 2 , next to ground pin .
is this the enable pin?
can somebody with experience help, I'm a bit of a novice & not really too experienced.
i have a multimeter & some basic knowledge & am willing to learn , please be kind as I'm very entry level but keen to advance my knowledge.
ps: sorry if it's been asked multiple times & I tried searching for answers & no luck
also am aware of bad amd gpu on these & have baked this guy in oven & no luck , also checked board for damage or corrosion & nothing appear wrong.
does beep with no ram & does boot to os as far as I can tell with disc spinning & keyboard lit up .
is the gpu dead & if so should it still be booting up ?
if gpu is dead should the screen have no lights ? Including backlight?
cheers
