Eh... I would at least test parts on the chassis.
You said the image collapsed to a line. That means something in the horizontal or vertical sections went. I know on a 21 inch viewsonic I found, the horizontal had collapsed and upon opening it I immediately spotted a fried transistor on the main board. |

I'll test parts on the chassis tomorrow if changing that resistor on the neck board doesn't help, which I have a feeling it won't. I'd rather not mess with the chassis since it looks like it will be a pain the posterior to get the actual pcb out of the metal cage it's in, but every second I have to stare at my backup 17" makes me want to fix that Trinitron more and more. It seems so round (since the Trinitron is vertically flat) and so small.
Also it collapsed into a Vertical line, so no Horizontal deflection. |

Changing the resistor on the neck board had no effect, and Rat Shack didn't have any 10uf 200v capacitors, heading to Fry's tomorrow. What's funny is that the resistor read 150 (incorrect) yesterday, but 220 today (correct). I changed it anyway.
I tackled the chassis today. I found a .2 ohm resistor that reads anywhere from .4 to .7, it fluctuates wildly, and another 2.5M resistor that read .4. I will try swapping these out tomorrow once I buy replacements from Fry's, but I'm losing hope on this monitor. I really doubt those two are the problem, as they were some of the first I tested and they were bad. By the way, I test all of these after removing them from the board, 9/10 times I get funky readings if I don't remove them from the board first. |
