can you tell me ??

why you make sugest that CPU and RAM is damage, so you must REHOT them ??

ohh... I think its time to buy new one... if this problem can cost too much money then its better to buy new one. I have also the same problem with this one before and I tried to recover it and cost around thousands because according to the technician it was the RAM then i pay him to fix it but still didn't work

Both ICs are glued!!!!

They can't be reheated, either remove glue and reball or change them ???

Fake solution..

what do you call mild heat?
how much degrees did you reheat at?

to all mates, i think our mates he just do mild heat to this parts...
otherwise we cant remove or reballs the ic coz its glued from the PCB
so this solution sometimes its work sometimes not...

just try it for ur own risk.
