I think that the processor sp9203 is a little warm but many Chinese TV boards have this kind of function. The tension is correct. Have resofting bin but no good news. What can it be? BOARD : CV9203H-Q42 DISPLAY: BOE HV320WXC-200 or CV315PW07S

the trouble was solved changing the processor . it is not easy, must much
attention and i think that is more better to change mother board if you not
have reballing station or enought experience.
