    Check wiring to A-connector, battery power - usually pins A1 ore A9, wires 219/202, fuse F40, ign power - usually pin A3, fuse F24, wire 180.

    check connector on fuse panel, from underneath, check fuses for reliable contact.

    With pannel anscrewed and ign. on try to toch and move a bit wiring to locate bad wiring ore connection

    If it's not loose wiring then the cluster itself is bad and they are about $2500 to replace

    Yeah, sometimes they fail. But this is an expencive thing and I do the cheap stuff first.

    If I see wiring is OK, I disassembly instrumental cluster. Bad soldering inside is a usual fault. Resoldering usually helps

    what is the VIN ore dashboard #. What year is the of truck? There are six versions of dashboards so I may be wrong with pin numbers.

    I've successfulley resolder the pins that connect from one side to the boards. They do fail from colder solder joints and new ones are $$$$.

    I have just the opposite problem, main dash panel is fine, but I lost all the lighting to all the other switches, on an '07 780.

    This is LCM failure. Check for LCM codes. The dashboard lightning is controlled with separate BTS switch inside LCM, becouse PWM brightnes ajustment is used.

    bad soldering is '07-09 issue. easrly Version-II trucks were more reliable.

    Be especially carefull choosing trucks with EBS and I-shift. Volvo use BGA mounted processors and sometimes there are sildering problems, especially in points that vibrate, like transmission.

    Its a 2006 VNL 670. I pulled the instrument cluster fuse and it seemed fine. So i put it back in and the problem seems be gone, at least for now. Thanks for your help, I'll check the things your suggested if it pops back up again.
