25" Hantarex Polo Troubleshooting

Thanks.

I'm sure i will make some mistakes,in somethings i say and need
to be rewitten, just pm me and i will edit it. When i write it wrong.

These chassis can need alot if your not going the replace a few parts
and restore the circuits,then forget it and get a Wells gardner Etc
med res. I don't see other model to be interchangeable.
Need to list your CRT #A and yoke # and readings.
I have a list of the ones i have seen, they have different readings for size'z.

I find the High Voltage regulation to be a problem.
Due to the Retrace and Safty Caps.
They open up under load the HV jumps up and Slams the HOT
enough of this and it can short winding in the fly.
Then agian We seen the fly spark out the side and the HOT still be good!
The fly could fail on its own, and short the HOT, If it bad.
I wouldn't replace it every time i did a cap kit!
Sometime's during TS it may eat some HOT to get fixed right
If i try replacing just few parts and not all the ones i should replace at once!
If HOT has been overheated it needs to be changed.
Or it could fail own its own. Bad connections can be another problem
Its the type and age of caps used in the HV circuit thats all.
Thats my take on what i believe is why they don't last after
just a cap kit and fly and HOT. And Upgrading the HOT is more because
the older is obsolete and uping the collector /emither current
won't fix the problem,in my opinion.

not trying to take over the thread, but it looks like I got orange goo coming out the top and running down that metal clip on the flyback. bad flyback or is that some kind of epoxy? I've never seen a totally blown up flyback before.

also, what other components should be changed out in addition to caps, flyback, HOT, etc.? arcadecup Chad was telling me something about the poly caps in the power supply section, supposedly those go bad sometimes, and I wouldn't object to replacing them, but I'd like to know what they are. lol
