Can anyone point me in the right direction please?
On an Orion Electric 'Vision PM4204' plams monitor I have the top half of
the screen working fine, but the bottom half changes intermittently between
total black and correct picture. What are should I be looking in
Thanks
Nick

If you're lucky, a loose connector or cracked solder joint, otherwise you
should be looking at a new set. Does it respond to tapping, temperature, or
vibration?

Hi James, thanks for your reply, at least yours is sensible. It may be
temperature dependent, but it's hard to tell. Fortunately I have been given
the set, so I am not to bothered if I can't fix it.
 
Look at the Y drive. If you don't have service data good luck, in
fact good luck anyhow because most of these no name sets are not meant
to be fixed when they break. Parts are just not available. If you're
a tech then you'll pull your hair but maybe the IPM is bad, you could
just sub parts out.

its X drive board or drivers after this board.check the boards that is
connected directly to the screen by flexible cable.Some IC chips drivers
could be bad.Try to swap them for example bottom boards on top and top
to bottom and see what happens.If its will be the same replace
X-board(the huge board usually on the right hand side of tv if you will
see directly on back cover of tv)If you cannot find it I can help you.I
need just brand of tv,model and serial number.Thanks
