Title: PROBLEMS WITH KORTEK CRT TUBE Post by: osewe on September 20, 2012, 02:23:54 PM Hi i have several crt tubes for kortek monitors that i have been using with igt machines and they have developed a problem of shorting hence i cannot use them. Is there a way to fix this problem .Has any one encountered such a problem?
Thanks Alfred From Kenya Title: Re: PROBLEMS WITH KORTEK CRT TUBE Post by: cowboygames on September 20, 2012, 03:12:26 PM If the guns inside the neck of the tube are shorted you can try and tap on the neck with the handle of a screwdriver after the unit has been turned on and had a chance to warm up. I used to do this with a lot of Zenith tubes in the late 90's. If that doesn't work you'll have to try and find a tube rejuvenator
