I have a K7000 (probably a K7191, that's what most of my chassis seem to be, oddly enough) that every now and then will flicker and the image will squish after little horizontally, and stretch a little vertically (it also looks like it squeezes in like a pincushion effect). This usually lasts for maybe a second then goes back to normal, might happen every once in a while when I'm playing MKII. Earlier today it did the same thing but this time it did not correct itself, and then after a minute or two, I lost all picture. Rebooted, still no picture. I had to do some stuff so didn't mess with it, but maybe 30 min later or so I turned it on because I wanted to check for neck glow/raster, and it fired right up as if nothing was ever wrong. Any suggestions on what to look for, in addition to looking for cold solder joints? I did a full cap kit about a year ago and I *think* I did the flyback, but I may not have (haven't pulled the monitor to check yet). Attached a pic I snapled when the issue happened earlier, before the picture went away (just imagine a monitor that's not turned on for that case ), and then another when it was working as usually a bit after. Thanks!
Also one more note: the image did seem a bit darker when it did the squeeze/stretch thing, I think that comes off in the pic decently well, as if maybe the G2 was turned down - sorta makes me think flyback, but I'm not sure.
