So just after an update the monitor starts to flicker….
After an in depth investigation the feeling is that it may be hardware rather than software…..
A complete strip down of the pc de-dust and re-seat of all major components and the issue still persists…..
Faulty capacitors on the monitor power board now seem to be the most likely culprit as alternate monitor functions fine on the same output!
Yet another board to strip and re-solder 🙂 At least its a known fault I suppose? getting harder to lay hands on parts other than the internet 🙁 guess I’ll have to wait on small screen….
Changed the 470uf and the two 1000uf and the monitors back in working order 🙂 under £5 fix 🙂
