Video Monitor Help

I volunteer at a small museum that has a bank of Panasonic WV-5490 CCTV monitors. One of them now blows the unreg dc fuse. Isolating different sections, I traced the problem to a low resistance reading in the horiz osc/hv section, whose operation has always been a bit of a mystery to me. I have limited eqpt at my site workbench, a Fluke multimeter. I could use a schematic to help me trace the problem further. Google only found tech manuals for $20, which they can't spare, and being the pix quality was only marginally good, probably needs a new tube eventually too. Any help would be appreciated. PS: They dont throw anything out. Thanks, Rick

Gosh, no helping hand at all? The museum is the Battleship New Jersey.

Not many people repair these monitors, so the manuals are not readily available. I would check with local TV stations, Military bases, School systems, and places that install CCTV equipment. One may have the manual, or even donate a used, but working monitor. You may even get several donated, as long as you're a non profit, and can give a receipt for their donation.

If that fails, they should see if someone will donate money for the manual.

Shorted horizontal output transistor?

Bad flyback?

Shorted poly cap in the width circuit?
