Sharp Image Monitor Troubles - K7000 clone

As far as finding what components might have blown - I suppose I need to go component by component and check them? What types of components are more likely to be burnt out?
Check the FAQs and flowchart. They go pretty deep into the common places to look for problems and how to fix them.
yeah - screwing something up is usually a good way to learn, just an expensive way.
Lots of the repairs I've done on my boards have cost time troubleshooting, solder and a dollar or two of parts to fix (before the cap kit or flyback).
 
SnakeRake, I believe I have the same chassis as you do, but I'm missing the adjustment board with the pots on it. I'm wondering if the numbers I see on yours are the values of the pots? Can anyone chime in here?

Are you able to take more pics of that board? The back of the board with the traces would be great, or if someone here has any leads on on of those boards.

I guess I'll pull the chassis again and check the pots, they have plastic covers on them so it's difficult to visually inspect them. I reflowed solder around the connector for the pot daughter board when I did the caps. (Sucked out solder and replaced)

I don't seem to have a frequency pot, I found adjusting the h position and h hold pots lessened the shear into a curl that waves on a off in a constant pattern. I adjusted the v hold to let the screen roll and noticed the curl follows the top of the picture, not the top of the tube. The curl moved with the screen roll

I tried to adjust the width coil and it's still unresponsive, but I noticed if I lowered a metal Allan wrench into it, it would affect the width a little depending on how far the wrench was in. Do I need a new width coil?

And I still have this subtle repeating wave that wobbles the picture as it passes by - could this be some sort of ac interference?



I had a nearly identical issue with a K7000 in my MsPacman and I tried everything untill I bumped into this article from bob, turns out, that I just needed to disconnect, set over the sync connection as stated and all was right in the world, couldn't believe that it was the issue but it was

Thanks for the info! I'll take a look, I think I killed the board, but I'm sure I'll try to resurrect it eventually. Ha.
