Hi
I have been trying to repair self powered speaker box. The digital screen does not come on. There is a microcontroller that sends signals to the screen which is connected to a flash memory "p25d80h".
If I place solder iron on ground or clock pin of this ic and on the system everything works. But as soon i off and on the system it dont work. For it to work in have to heat one pin of p25d80h. How can I fix this issue. I have resoldered both ic so it is not cold solder or ant bad joints.
