TEK 2465 with screen issues.


 

Arrived from a friend before 1 week. Problem shown on the video.
I changed up to now the following components with another 2445, as to check what work and what not. All the above work good.


1. PSU
2. Controller board.
3. Readout board.
4. Front controls board.
5. All the hybrid ic's.
6. Display Sequencer.


The PSU output voltages is at specified range. Intensity control not setting down full the beam.
Have someone an idea where to start looking? I mean with the measurements..
