You should always measure if you have any voltage to the vertical IC. Then you know that the circuit supplies voltage to it. But yeah, hopefully it's the IC. It could be a transistor, resistor though.

Yeah, also measure the resistance for the v-yoke and h-yoke leads and then between h and v-yoke to see if you have a short also.

Try to measure the resistance in the h-coil while adjusting. That way you can determine if it's working or not. Are you using a plastic tool because these coils can get very brittle and break. I've had a case where I wasn't able to adjust the width because of that.

What?! So, the previous owner plugged the AC power into the second yoke connector. Well, there's your problem.

Hmm? So, let me get this straight. When you adjust the h-sync (out of sync) the screen goes fullscreen but not steady and when h-sync is steady, it's cropped/squashed? Is the h-coil rhe only way to adjust the width of the picture?

Picture still looks kinda green though? Have you tried measuring the R,G and B voltage going to the neckboard if they're equal? Green looks to high/dominant.

Was it 3 years ago the monitor got recapped? If your voltage is 134V and it should be 127V, that could have caused some caps to fail or loose capacity, maybe? I took a quick peek at the schematics and try checking the caps again in the horizontal deflection circuit. Try checking transistors...

SABA PM25 - Need help figuring out the problem (VIDEO) Hi all! I have a SABA PM25S42 CRT that has this weird picture. A white thick line at the bottom, purple picture and no H-sync (as far as I can tell). Before this, the TV died and wouldn't start. It just went "tweet, tweet, tweet" I found...

Sounds like there's a shorted cap or the transistor that drives the vertical deflection? Generally, both the v-def and h-def connectors are different, they're keyed so you can't put them in the wrong place (if they're seperate), the pins are differently spaced. What kind of model do you...

Sorry didn't notice that this forum had a monitor section. My bad! I'll make a new post there. This can be deleted.
