Hello,
I have a Nanao MS8-26U from a virtual fighter that I am trying to repair. The monitor had no picture and the anode was never being energized. On first inspection I could see that the secondary fuse was blown. I did a search on this forum and found that some else had a similar problem which involved replacing Q533 (D1880) and Q901(C3306) transistors. I removed and tested these on my monitor, and sure enough they were both shorted (collector to emitter). I replaced them and powered up the monitor. Hooray! tube is energized and has a square but fuzzy image...but wait is the image getting brighter and brighter? POP! both transistors blow again! I have tried to test every component around the +b ADJ and anything else that looks like it might lead up to the HOT. But I can find nothing else wrong. Any Ideas would be appreciated.
Thanks.
