Hi All,
I got a 19K7900 in that worked fair with some minor issues. Decided it just needed a cap kit. While doing install, I noticed it was missing IC4 (Volt Reg.), so I installed a good used one, and put everything back together. Monitor would not fire up, and big white resistor on side got very hot. I than pulled chassis and removed IC4. put chassis back it and fired it up. Picture looks great. There is a very slight wave in picture, and my B+ is 109vdc. Supposedly this monitor has been in service for a while this way. Any Ideas why it works so well with out IC4, why does it not work WITH IC4 installed? How do I now get rid of the slight(hula) wave?
Thanks for any info
Aaron
