Hi
Recently i have problems with flickering tubes on my 1209 and sometimes the tubes turn off altogether.
Does anybody know what could be causing this?
Best regards

Does the red light on the EHT board come on when the tubes go off?

My 909 one was a bad quad the other time the convergence board blew up next couple of times of use with a short that riped up a trace
The quad tone the projector log showed eht fail the convergence board nothing logged.
Looking at my convergence tray the old thermal pads where dry and bad maybe cause
The mosfets to overheating 🥵 we should all re thermal pad everything???

Hi for some reason now there isnīt any flickering. I tried both yesterday and today. I saw some small hints of flickering very short but that was it. Also there was no reaction from eht board.
This seems very strange. I havent used my projector in a while and then i watched a movie a couple of days ago. I donīt if that could have something to do with it?
