There is a lot of debate as to the cause of the problems which P169s seem prone to giving. Previously in YSTV, some improvement was found by replacing the two large capacitors which are related to the power supply. To me (--[[User:Malcolm.chambers|Malcolm.chambers]] 16:14, 24 December 2009 (UTC)) this seemed a very strange cause particularly since, after the mammoth reordering of the Vision path and control room at the end of Summer 2009, genuine VT P169 started failing on most inputs and outputs, but DaVE P169 only experienced problems on one input and one output. the only thing I could think of that would cause this is something which would affect only one or two of the ICs in the P169. Such as heat damage. Following this I reorganised a couple of things in the rack, to allow more air flow around DaVE P169, and there hasn't yet (24/12/2009) been any deterioration in performance. | There is a lot of debate as to the cause of the problems which P169s seem prone to giving.

The genuine VT P169 mixed its eight inputs and sporadically sent this 'crazy scrolling combination' to some of its outputs. This was of course completely unuseable. It was hastily replaced with VT 'P169' which is actually an 8x4 switcher with slightly limited functionality of the actual P169s. | The genuine VT P169 mixed its eight inputs and sporadically sent this 'crazy scrolling combination' to some of its outputs.
