Hi,
can anyone help with a manual/circuit for this model.
Fault is no picture, sound OK. Y main panel was faulty, have swapped this, now the Vs supply comes on initially, but dies down fairly quickly. Don't think its the PSU but not sure.

Hi Mark,

Tried unplugging Y-Buffer from Y-Main and checking if Vs stays up in case you also have a duff Y-Buffer.
Look in downloads section, bottom right column for "last downloads". Mind you, most current service manuals are as useful as a jockstrap in a blizzard (and about as much coverage). I've also added the "fast track service guide" Bruce

Hi,
Thanks for the manuals. Have tried disconnecting buffer, still the same.
Have found that if I disconnect the cable to the small main control panel voltage stays up.
But I have already tried replacing this panel. Unless the replacement was faulty!
