WebAug 20, 2024 · Check R461, it looks like the vertical runs off the B+ but runs through that resistor first. If it's burnt up it looks like IC401 may be shorted, if that's not it check R454 and R456 which are what power the deflection transistors.

WebThe vertical deflection circuitry is less important, so it would likely cut out faster. So, you end up with the beam ending up stuck in the center of the screen, and the horizontal circuitry surviving a bit longer and making a line across the center until it finally ends up as a little dot in the middle and stops entirely. co op horwichWebNov 24, 2024 · You have a vertically rolling picture with foldover. Most MS8-26 issues can be fixed with new electrolytic caps and reflowing solder joints. It's a crazy well built chassis. Do you have a 26SG or a 29SE? Take a pic of the chassis if you're not sure. The chassis is not auto-discharging, so make sure to manually discharge. famous athletes from fort wayneWebThis set, a JVC TM-910SU, had a case of partial vertical collapse.
