Hey folks,

I was wondering if somebody has an idea on how to fix this bleeding (white, going from left to right) on an arcade crt.

@Mitsurugi-w maybe? :)

Any hints and ideas welcome,

Sascha

That is something almost all CRTs have a problem with, mostly white screen. The effect you get when the picture expands on a white screen is called blooming. Sometimes it indicates bad caps or a failing flyback. Sometimes the design of the monitor just causes it to be bad.

Sometimes the brightness or screen knob is up too high.

It's a "New Astro City" cab and I think the CRT is a Nanao MS9.. Will make sure that's actually the case.

I tried the brightness knob because it's in the front, will try the screen knob soon tho. Thanks for the hint, I'll let you know how it goes!
 
Get in touch with this guy. http://www.jomac.net.au

He's the Nanao Chassis repair guru and can fix most other chassis's also. He also only deals with people in Australia so your lucky. I wish I could send him all my stuff but he doesn't replies to emails from out of the country.
 
Thanks guys! I'll give turning down the screen knob first tonite. Otherwise I will reach out to Jomac, even tho removing and sending the screen via courier scares me a bit :)
