2008 BlackBook Three Beeps plus Freezes when flexed.

i think blackbook died sort of. computer won't turn on , gives me three-beeps means logic board messed or whatever was. happened before, replaced logic board, , good.

time, got unit turn on, when case shifted or creaked there vertical distortion in lcd screen accompanied system freeze. happened 2 minutes in when remembered check.

have gotten boot 3 out of 20 times far. when boot usable until move innards wiggle. took apart , visually verified of connections connected. not know problem or google for.

3 beeps after post or whatever, before loads.

put on table , made booting sound, screen flickering horizontal bars , vertical green bars.


twisting diagonally left side raised , right front corner tilted downward fixes screen not change boot process, stuck here.

booting twisted hear right speaker make crunching noise quick, , try made last half second of apple boot noise loop.



if runs fine. when pull iphone gets crazy screen distortion , when put frozen.

can't logic board because computer works fine, remains powered, video card? on daughter board or something?

 

my guess gpu - soldered onto main logic board - soldered lead-free solder - may worth try recalled (with proper lead solder !!)

on ebay , see if can find somewhere not expensive......
