I am struggling with these chassis. any help would be great. One is the ms8-25b, this chassis doesn't have r-433 or c-433 it is completely different. I started with it shutting down on power up. After some caps & turning the B+ way down, it now stays on but has vertical collapse even after vertical caps & IC401 was changed [LA7833] I would also like to know what the B+ should be set at? Any ideas? I also have 2-27" chassis nanao it doesn't have a model # .the chassis C/B is stamped #05A00585D1 shutting down on power up even after changing caps in the B+ area. I checked Q-901,D502'&Q533, they seem good? Did I miss a cap or something? Also would like to know the B+ of this one? Would love to find some schematics too, I know I am asking a lot but any help would be wonderful. thanks sherry-vintage arcade
 
Sherry, it is not a good idea to ask for help on 3 monitor chassis in one thread. They each should have their own thread to avoid confusion.

It also appears that you are shotgunning parts into these chassis' hoping to win the chassis lottery.

Start by doing a "Full" cap kit on each of these monitors, because it sounds like they all need it. Check back in after you have done that.

Hi Dokert,
I am new at this forum stuff just learning.
I got a copy of the cap set for the ms9-29su, I'll try that and let you know.


Thank-You for your help & advice
