So from reading I am assuming I can not replace the flyback(unless I missed a posting on this fact).

I have a 19" k7000a pulled from a PC10. It was blown fuse no neck glow. The fly looks good so I go ahead and cap it, HOT, Voltage REG, Diodes. Being hopeful. At start Still blowing fuses. Any recommendations or should I just be done with it.

What volt reg is required for a 19" K7000a??

What are my options as a swap out for the chassis??

Find the vertical size cap. Not sure which it is on the K7000A, but on the K7000 it is C38...
 
Yeah, I meant horizontal. If it doesn't test shorted, it probably isn't.

You can try isolating the power supply section and test it under load by using a light bulb (lamp is easier). If the fuse still blows, then it's not the flyback.

You ARE using it with an isolation transformer, right?

You may need to invest in a ring tester to check the flyback to know for sure if it is bad. Or get a regular working K7000 and put it on the tube...
 
If I remember right....a flyback can pass a ring test and still be bad? But yeah....isolate the power supply B+ and load with a 60 watt lamp to see if the issue is in the power supply or the horizontal section.

Bit of an update.

Since my chassis was pulled and being rebuilt I was a bit weary of this idea but I decided to pull my friends working k7000a and transplant it. Of course I didnt even think of this idea after 2 days.

Outcome was a whining white lighting neck on the tube. I had read somewhere about this where the tube was damaged. Currently my search is not coming up with any threads.

Since it was still blowing fuses theres still an issue with the chassis obviously. Will rebuild and test on his monitor and update.

Best part is I sold him his working recently since I had this one thinking "eh I'll fix it."

Is there a way to test for this issue? Minus hooking up a working board to check(for future reference)
