Looked at it again today. Was bad d706 cause no HV. I don't know original part number (Anyone know?) but I put in high speed rectifier from another Mon to get it up for now.

Anyone familiar will Nanao MS-2930 HV circuit? Symptom is no HV. Unfortunately no schematic/ manual I can see and can only compare against MS2931 which is too different here. - Flyback tests good. (swapped another to be sure, same) - Tried swapping u701, same. - Q701 tests good - B+ measure...

Can you confirm this? Swap red/blue to be blue/red on the same header..... Or red/ blue to brown/gray header. They shouldn't fit.... But...

Actually now that I look at schematic again R101 is wrong as well. Is 102 - 1kohm resistor. Basically if anyone is looking at schematic for MS9 troubleshooting take it loosely at value. This one gave me unnecessary trouble trying to sort out this problem looking at wrong info.

I was able to get it up and fixed. Thankfully I had a blown open r101 as well which save everything. But yes, schematic is wrong I swapped in pnp S9015 @ Q101. Working normally now

I think MS9 schematic may be wrong? I have a few of these various chassis for my games so that is how I am able to easily bounce to check parts and swap. I have an auto sync Nanao MS9 with no sync. I believe something shorted to ground and wrecked it long time ago. Unfortunately no good...

There are parts on the back that are different. It's been something I've had on the to do list for a few years now but haven't gotten around to doing. Maybe one day

This is a calculator you can play around with input different spec to see impact of different value. length, guage, etc at different voltage and current. might help to better understand how it will affect if you play with it and see output values :)...

Hello there you will want to glance through the cr7000 manual. Those emissions are in the "bad". You will want to look closer to this:

If you wish to cover the exposed traces again you can order UV curable solder mask fairly inexpensive like this C$ 4.35 | Mechanic UV Curing Solder Mask Ink, 10ml, Green, Red, 6 Color, PCB, BGA Circuit Board, Insulating Protect, Soldering Paste, Flux Oil https://a.aliexpress.com/_mKq1QxC

Did you check the HH15 pot as well? To adjust and actually measure to make sure didn't accidentally break or something.

Can do these first two with the Mon off... For yoke connector/cable it is simple - you will use continuity test of multimeter. You want bottom of chassis PCB (use solder point before final header pin if you can to fully verify) to the yoke itself. That will verify your header pins, solder...

Also go slow and follow schematic if there is one. A bunch of those things won't have anything to do with vertical collapse (things like hot, filter cap, the vast majority of caps on the board, etc). Try to narrow down and troubleshoot in the vertical section to save time and money 😎

Have you verified the yoke and yoke connectors? If you have then it might be time to get out the old oscilloscope and get probing to see where you are losing the signal.

You could look at putting in a power supply with a sense line

Yes plus there is lots of white by the looks of it (credit, Character images,) so seems all colours present

Does not look so bad to me (as in very likely fixable with only calibration and not part failure). If your colour drive transistor is problems then you will lose colour completely or colour is completely on. When it is fully on you will see very colour washed screen with retrace lines. This...

You are still getting movement on the meter when you adjust the red cutoff right? Also you know your rejuvenate machine is working correct yes? You've used on other tubes? (Gotta double check basics first!) Considering the strength of the green and blue I would be pretty surprised if you...

Those are Transformers. They are an iron core with very thin copper wire wound around a plastic piece then there is a protective layer around the wire on the outside. You do not need to wait a month unless you are in the middle of a project and don't need it anyway. If you heat dry them you can...

Yes that's fine, just made sure they are completely dry before applying power
