DVD player hangs on Power up

Mine also has the same behavior since new and the damn thing will work fine at the dealer's place. It does not have relation with the cd.
This happens due to humidity, as pcb laminate is of inferior quality.
With the dvd players so cheap, they may not afford a good laminate.

U may be able to rectify it by coating the pcb with a protective spray after heating it.
