Title: Re: Ways to repair ghosted crt Post by: JerTM on June 03, 2016, 07:48:08 pm Yes, sorry I'm a noob. Now the question is can I get another screen and if so where would be a good place to look and how can I identify the screen I need. Thanks for any help.

http://arcademonitor.com/Arcade-Monitor-Parts/ Please before working on this watch Johns video on discharge the current monitor first before working on it. Changing the tube is pretty simple but you have to discharge it first even if its been off for awhile. IT can severely hurt or injury you, or kill you. But its easy to do it, just follow John here: https://www.youtube.com/watch?v=YfQbdvB8GSM Good Luck! -Greg P.S. Adding if this is a Vector monitor (Tempest, Asteroids, Battle zone, Star wars, etc), then you need to add a resister or use a HV probe to discharge it slowly vs a quick discharge. If you dont know post the game name up here or just look at the writing on the monitor and Google it.

There are non left. Here's a link to a museum that is trying to get into rebuilding picture tubes. I'm sure if they get things working correctly they won't be cheap to have a tube rebuilt. http://www.earlytelevision.org/crt_rebuild.html Also a few years ago while searching online I found a company that was still claiming to rebuild tubes however I never did try to call them and I really don't know if they were really still in business or if it was just a left over web page that simply hadn't been shut down. I don't remember the name of the company but if I happen to come across the web page I'll post it. Title: Re: Ways to repair ghosted crt Post by: P-feif on June 07, 2016, 09:30:06 pm Well this is not the web page I was looking for but found it interesting. Looks to me like it's a costly thing to have done (if they can still do it).
http://www.videodisplayprojection.com/ I found that old link but it's dead now so I'm not going to bother posting it. Title: Re: Ways to repair ghosted crt Post by: JerTM on June 08, 2016, 10:27:08 pm Thanks all, looks like I will just live with it until it dies lol
