I picked up a pair of Bestech btm-19cm chassis listed as not working. I'm aware of the negative sentiment about these, and I am sure it has been earned, but the price was right for a couple of project pieces to learn on.
I recapped one chassis with the exception of a few caps on the neckboard that I had no replacements for.
I hooked it all up, got neck glow and a picture. But the image was not stable. I adjusted the v-hold and h-hold and managed to get it steady.
The image was bright and the color was good, but the horizontal width was too large. I adjusted h-size to the smallest I could get on the pot, but it was still slightly too large. I did not adjust the coil.
Suddenly the picture and neck glow stopped and I was greeted with a clicking noise. I believe that this is a protection circuit? Subsequent attempts to turn the monitor on have been met with the same clicking.
Does anyone have documentation on this monitor? In my reading it looks like this may be related to a bad flyback or Horizontal Output Transistor. I have not had much luck searching the part number for this flyback. How would one go about finding a compatible replacement?
