Help with bleeding on arcade crt

[CoinFeeder]

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.

Chassis recap/service? What kind of monitor is it?

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!

A recap couldn’t hurt either

Indeed. I had my MS9-29 serviced and it's awesome - even if it's not that bad at the moment I'd say it's well worth doing

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.

Didn't realise you were in Australia - if that's the case, without a doubt send it to Jomac and he'll have it sorted.

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

You only send the chassis not the tube, Joey will tell you what to send and how to send it
