Hey,
I've got a D9200 in my Police 911 2... right now it's basically dead, but it's had its ups and downs, and since I'm not too familiar with that model, I'm gonna see if I can get everything to fix all the problems at once. To start with, it was working intermittently, and going from full screen to half screen... but I pulled the chassis and found tons of bad solder joints (the flyback was barely still soldered in
), and replaced a couple bad caps and a burnt resistor.
But now the current problems. First, it's dead... I know the flyback is bad, since it was working with just a few minor issues, and when I went to adjust the screen control, it shocked me and then went dead. So, I plan on ordering a new flyback, but unlike the older monitors I'm used to, when I turn it on, it still has neck glow, and it almost sounds like it's still doing raster. Is it likely that the HOT died as well? I checked the HV w/ my HV probe, and it looks to be putting out about 2kV... not sure if this means anything about the rest of the components.
Also, when it was working, the picture was kinda wavy... not like the hum bar wave, but the whole screen would kinda wobble, almost like the degaussing coil was stuck on or something. I'll probably order a cap kit for it when I fix everything else, but does that sound like a cap problem, or is there something else that causes that?
A couple minor problems are that the picture seemed slightly rotated, with the trapezoid adjustment I could get the top or bottom straight, but not both. The width also seemed slightly too big... with the H Width adjusted to 0, the picture was just slightly smaller than the tube in most places, except for the tip from the trapezoid. Are there any rotate adjustments, or width adjustments besides in the menu?
Thanks,
DogP
