LeRoy, Intermittent or load break down of yoke winding insulation, As i said, i have seen b-4, thats how mine was. No different then intermittent or load break down of flyback winding, which is still my 2nd thought. Also you might try spraying some freeze inside yoke area and possibly aggravate the symptom.

Reply�to: [EMAIL PROTECTED] (ELECTRONICS PROFESSIONALS LIST) Hi, Joe, Thanks for your input. The reason I wouldn't suspect the yoke, is because it works good when cold. I can't imagine a yoke causing an intermittent problem like this, but I guess anything is possible in this business. I'm going to try replacing Vert. output, and e-caps, before disturbing the locked down condition of a bonded yoke. I'll post my results later.

LeRoy, Been awhile, but have seen, if TOP HALF stays totally unaffected, and LOWER HALF horiz freq. way off (not just slightly). problem was definitely yoke or fly but (memory...???) says YOKE. I believe that has a bonded one to boot.... If so, you can remove it, and visually see problem area.... (yes I have removed bonded yokes)..... save as last resort, but at the same time if you have experienced removal of these yokes, it can be a relatively ez but a little timely check..

Reply to: [EMAIL PROTECTED] (ELECTRONICS PROFESSIONALS LIST) Hi Members, This CTC177BH3 chassis has a good picture for 30 minutes, then suddenly the bottom half of the raster goes into horz. lines, and has a vertical jitter. Lines are thicker at the top, and less thick as you progress down to the bottom. The top half of the picture remains perfect, and is not affected. I tried cooling the Vert IC, and associated e-caps, etc,...but, it does not bring the picture back to normal. I have done the tuner wrap soldering, and everything is tight. Any suggestions are greatly appreciated.
