My experience with repairing VT100s and VT101s suggests : - Logic fualts (both the main logic board and the keyboard logic) are uncommon. Apart from the 2 ASCIs (video timing and video dot path) these boards are easy to fix anyway. - Keyboard contact probles, cracked plungers and missing keycaps occur as you'd expect on this design of keyboard (it's the same design as the HP85 series, HP9816, original TRS-80 Model 1, VT5x, TI 99/4a, etc, all of whcih can be a source of contacts etc). - The PSU can fail. In the V100 it's a swticher. But it's one of the most reparier-freindly switchers I've ever worked on, in that almost all the controi circuitry is on the isolated, output, side of the PSU. - Video prroblems are by far the most common class of faults. Top of those is a failed flyback transofrmer, which is separately mounted on the chassis. The rectifier diodes o nthe video board can fail, sometimes accelerating the death of the flyback trnasformer. CRts can lose emission, but try cleaning the screen first if you can't get much brightness/contrast from one. -tony
