hi again guys! welcome psoma! still looking to solve this? hopefully we'll all manage to do this together.
just posting to say I haven't given up it was just couple of crazy weeks at work and I will get back to the monitor asap. hope you guys can wait a bit longer!
I have now checked ALL diodes on the motherboard (including D467/8 ... getting more familiar with the schematics) and all seem to be ok.. couple I had to desolder and measure off-circuit.
I will be able to do more measurement this week. Can you please explain what I am expecting to see at pins...
hi again!
-= bonus info and question on locking ring =-: I think someone has messed with the convergence rings before so I might have to play around later on. Regarding the "locking ring", I guess it doesn't play a role in the electron beams right? will it matter if its rotated or not?
I also...
hi @Relayer! thank you for your input. I have recently recapped the monitor and PSU replacing ALL electrolutics. I have also measured R472 to be 1k as it should.
I will double-check of course.
Regarding the convergence rings I am not planning to touching them (yet! :D) but I would like to know...
hi guys!
I have some answers..
pin 3 of IC403 is 12V, at SK2 also 12V, could'nt find R562. Also R472 is measuring 1K..
the main psu outputs 125V, 16V, 26V at the 4-pin connector.
I noticed today that except the vertical lines that indeed look like some harmonics as they repeat and further...
thank you Klaus!
I think it must be something else since the monitor works properly with image.. I just took this photo without something else showing to make the lines more obvious. When the monitor operates the lines are barely noticable..
@horttanainen thank you for your understanding! I created a new thread here: https://www.edaboard.com/threads/commodore-1084s-monitor-with-faint-vertical-lines.396322/
@Relayer thank you for your interest - I have attached a photo in the new thread!
Hi guys!
First of all what a great forum! Also Happy New Year to all :)
I need your help with my monitor which produces faint vetical lines at the left side of the screen (image attached)
.
I read some great tips and info in this thread and I created my own not to hijack that one...
Guys just wanna say this thread is superb and helped me a lot as well! I registered to the forum because of it and I am amazed from the amount of knowledge found here!
I wont hijack the thread, maybe when you finish repairing your monitor and I truly hope so - these are beauties, I will then...
