Ok so my Studio display started arcing and sparking like they all do, so I got a new flyback from Technotronic Dimensions. Nice fellow. I got it installed and it looked glorious! For about 10 minutes.
Then it collapsed vertically and horizontally into 3 dots. After turning off the CRT, letting it all cool down and turning it back on, the only life I get is a green power LED with 3 amber flashes at regular intervals. I have replaced the Horizontal output transformer (it had shorted out completely), the damper diode, and a few of the high voltage capacitors. None of the other caps showed signs of damage, and all the ones I tested with my LCR meter (before I forgot to discharge one and blew up my LCR meter) were within 10% of their ratings, about as accurate as that meter gets.
after mussing with all that and some more parts shuffling, the behavior is the same. There is also no high voltage coming up on the neck board. During all this I was in contact with Steve from technotronics, and he suggests that the new flyback might have failed from being driven too hard (I was using an Xbox 360 at 1600x1050 as a test source). Before I get another flyback (paying more than double what I paid for the monitor, *again*, I thought I’d open source the question to those with more wisdom than I.
what would be especially helpful is a schematic for this monitor and showing me some points I can scope out to get more data.
Thanks in advance.
i attached the only picture I have of this monitor running, as proof I was victorious once.
I really want to save this unit because it’s a perfect companion to my mom’s old Sawtooth G4.
