Prior to doing a cap kit, the chassis had a burn hole straight through the board at jumper, J19. I replaced the jumper and fired up the the monitor, to get only a small blue dot in the middle of the screen.
I went ahead and completed the cap kit, replaced the HOT and VR as well as the diodes at D501 - D504. Fire it up and fuse F501 is blowing, shorts the HOT and causing the ceramic resistor mounted above the VR (STR381) to get hot as hell.
I've checked for cold solder, bridges, everything I can think of, but no luck at determining what could be the problem. It's possible the flyback could be failing, but even that seems coincidental, since the fuse at F501 was not blown before the cap kit, etc.
I've followed Randy's flowchart but this problem seems to reside outside of it unless it is the flyback.
Any suggestions would be appreciated!
Thanks in advance!
