The LCD blinks like it's trying to turn on but then goes to blank and only displays the clock. The transmission is complaining about a missing VSS signal which goes vss>cluster>TCM and the fuel gauge doesnt work/is stuck on empty but the fuel light is off. All the needles work fine using the diagnostic test (3 button presses) and the instrument cluster is throwing every possible DTC. There's a little chip mounted on the little LCD daughter board that I believe is fried. Can't really think of anything else that would be causing the problem?
The wiring diagram shows that fuel, temp and speed all go through a chip. Although i'm not sure which chip as the rest of the cluster has a few soldered to it so it may be better to just replace the whole thing.
