Does anyone have a cct diagram for the above mentioned monitor?

Aslo have found the following s/c components

D925 1N5408
and an IRF634A

when these components were replaced, Monitor worked of sorts... before the above components blew once again.

When it was running.... the horizontal looked as though it was shorting. as vertical was ok, but the horizontal was wavering in and out.

any ideas?

Cheers

Try to use diode UF302G. Check for dry joints on FBT.
Insulate heatsink of your fet from ground (just cut tracks).
When you will cut tracks be careful: don't cut extra, it may interrupt track. Check also coil next to fet for shorts
and burnes.

Hi are you sure it is a 1N5408 and not a UF5408 there is a very big difference between thos two devices the UF can be used where ever you find a 1N5408 but not the other way round.

1N5408 is a slow diode and is no good in switching circuits.
