Seeking some advice on matching a chassis to a tube.
I'm guessing the 59 after the A tells me that I have a 23.23" CRT. The problem chassis on this monitor looks almost identical to a Wei-Ya 825H, but I can't find any specs on it. The part number from the PCB is HH-25/29C. Probably an earlier model.
So, when I pulled the chassis and looked it over, I assumed it was for a 25" tube based on the PCB part number marking. I ordered a new chassis from 8liners.com. They sent a Wei-Ya 825HR4 -- should have just got it from Alva for cheaper I'm learning...
Anyways, my monitor's resistance readings are right in spec (H=2.1, V=7.3) for this new chassis.
When I power it up, the screen it way to wide and off the right side of the screen. Turning the H.Size all the way down still doesn't do the trick. Also, the monitor now has a wobble and vertical bounce and you can hear a high pitched whine that's in sync with the bouncing. If I turn the V.Hold so that the screen is constantly rolling, the whine goes away, but obviously is unuseable.
I'm rather new to this CRT rebuild thing so I'm looking for any advice on what I should check next. I've been trying to contact Victor about exchanging the chassis just in case this new one is defective but like anyone else, they are quick to reply when you want to buy, slow to reply when you need anything else.
Thanks,
Jeff
