Cool. Orange is the display that’s usually on the military version that’s fully tempested. Worst thing about that is after removing the top cover all you see is all the additional shielding that the military required. The LCD and red plasma are way more common and don’t have all the shielding. If you’re using the internal power supply that fits in the bay you may want to look at the spring connectors or try a different supply, any twelve volt source will work. The little DC to DC inverter in the back next to the drive bay just provides +5 and +12 and is fairly straight forward design, and then next to that is the display power supply. The things that I have seen fail the most are the surface mounted filters on the mother board located under the battery bay and modem. Also look closely at the switch on the back along with its wire to the little Molex connector.
