Try flashing the phone. Several DCT 4 phone problems are solved by flashing the phones with a good MCU and corresponding PPM file. Good luck!

thank you Trion and gibso for your answers.

I found that if I squeeze the phone the LCD gets alive. When I release it, it freezes again or gets blank.

I think there is a bad connection somewhere, but I dont know where to rehoot. I have not worked with 7210 before.

check the clip connector of the LCD, make sure its clean and tight
also on the PCB be sure they are clicking together fine
goodluck
