Digital speedometer stopped working

[Army rigger]

Hello Everybody!
I'm hoping there is somebody here that can give me some insight as to why my digital speedometer has stopped working. I purchased a 99 metallic zenith blue boxster when returned from afghanistan. It only has 32000 miles on it and after a year of driving, it's starting to act up. About 2 weeks ago I got in my car to drive home and just as i left the parking lot I noticed that the digi speedo, odometer and trip odometer had all gone blank. I was able to see the orange back light but just not able to see any readings. After some surfing on the ole interweb I came across the fuse diagrams and checked my fuses B1, B10, and i think it was also E1. Everything was good so i put the key in the ignition and turned it over to see if it was working. EVERYTHING WENT DEAD! Now both the analog and digital units were not working, no fuel gauge,temp gauge,tachometer. Just the little red light telling me i needed fuel was working. I had NO DASH LIGHTS illuminating the cluster. All the trouble indicators would light up when you started the car but they didnt stay on so at least they were working. I made an appointment with the local Porsche dealer and took it in for a diagnostic praying to every god it was a blown relay or something small. He calls me the next day and tells me that my entire cluster has gone out and i need to replace it. He can order one and it will cost me $3000 plus labor. He said they inspected the pins and my cluster was getting power but it was just not working. I payed the $150 for the bad news diagnostic and drove it home. This being my only vehicle i kept driving it to work and the other day as i pulled in and turned the ignition off the Porsche God must have heard my prayers because Everything came back on but it was in KMPH setting and odometer read 999999. It's stayed on for a few days now and yesterday the digi displays went blank again but my analogs work. Obviously my cluster isn't dead theres a short somewhere, maybe in the ignition some where since thats when it started working again was when i turned off the car. 1999 boxster 5 spd manual.
