Marconi 2955 scope problems
« on: December 28, 2019, 09:48:36 pm »
Need a bit of help with an old Marconi 2955 I've had this machine for years and 99% of it is working fine, I've been using and repairing these machines since the late 80s and I'm familiar with most of the circuitry but this has me stumped,, the scope has developed a fault and the lower 2/3 of the screen is just green with a little bit of signal on top.

I used to have a spare unit i could swap boards out of but since acquiring several other machines i didn't need it so repaired it and sold it, I've searched all the forums and have found no info so i just hope someone out there has come across this problem before.

Ive got all the manuals and it has version 16 software
