Hello all
I have dead instrument cluster from Volvo FH4. He died while drivng the gauges stopped on 86kmh and about 1500rpm. Then I connecten on a bench i have 5V supply and 3,3V supply on PCB but nothing happen. Someone knows what's common issues with this dash? I think the problem is with BGA MCU because i have 2 supply voltage and nothing happen.

I heat the PCB and after that dash gave a sign of life. CAN signal appeared and gauges moves a little, on green and blue section voltage awhile appeared for but screen shows nothing.
I don't know a can frame with ignition on to wake up the dash.
