2005 GTX 155 Gauges and Display no function

[kolinrr]

Hello guys,

i bought my gtx 155 from 2005 couple of month ago.
With couple of problems, but I was able to fix lot of them. My instruments are not working at all. I checked the connection - i get 12v on power line and 2,45 on BUS lines.
Also as soon i put my key on, i hear the long beep (no instruments communication).

After i opened the instruments housing, i found the dead diode on +12v on the connector plate inside (see photo), replacing of them don't fixed the issue. Gauges and display still not working - no initial run.
Gauge-Motors are fine and very smooth in motion.

Do someone have an idea, what i can do more? Maybe some of you know, which parts gets mostly dead, so i can check, before i invest days in understanding of the circuit plate?

Thanks a lot!

P.S. I'm living in Cyprus (island), so repairing service in US would't be a solution, because of the price of the logistics.

I don't even mess with those clusters anymore. You can buy the newer China cluster style for less than $100 and swap it out with just a minor modification to the hood.

I went through two clusters on my 2002s, but that was when you could still buy a new one. The problem is once you pull them apart ... good luck getting them to seal and vent properly again. Good to know there's at least a knock off version available.
