Issues with a Bestech 25" CGA chassis ... clicking sound
Hi all.
I've got a UMK3 that plays blind. The monitor chassis is making a clicking sound.
I removed the chassis from the tube, and included some pictures of it below.
How do I go about repairing this? I'm pretty much a n00b for monitor repair unless it's a G07.
I've got decent soldering skills, and I'm not afraid to take parts off and put them back on. I just need some help figuring out what to check and fix. There's no documentation or schematics on this thing.
I'm assuming the HOT is shorted out. Where would the HOT be exactly on this chassis? Any idea.
To test it, is that just a diode check with the RED lead on the outside leg, and the BLACK lead against some other grounded metal? Should get some resistance. If I get none, then it's shorted?
If that is the issue, how can I identify the parts that need replacement?
Thanks,
Steven
