Philips SA3125/02- turn on only after heating !?
 

Hi, I've got mp4 player as in thread.

Philips SA3125/02
Hynix HY27UU08AG5M
Sigmatel STMP3504

Player don't turn on in normal conditions.
But when I heat up the Sigmatel IC then it works perfect.
When Sigmatel is cold again then it is freezing and won't turn up till next heating.

If it is necessary i will upload photos.
There is a link to manufacturer's page:
Philips SA3125/02

I am waiting for any response. What can be a problem?
