Hello,
I have one speedo with 908LJ24. I desolder MCU and solder back and speedo now won´t work. I change more mcu and without problem. Desloder with temperature about 350Celsius.
Solder back using flux and tin no clean and after soldering all time clean by IPA.
Any ideas what can be wrong? Pins no connected together.
Dash work max for one hour and after this time shot down.
After I resolder for example one side of mcu and connect again to the power is the same.
Many thanks for kick of right way. :-)
