i did notice that i had replaced the videooutput tube thinking that was the problem but i had put a new one in when i got the set and from the start the brightness was not what it should be so months later with very little hours using it i decided to change that tube i tested it and it was completly dead. i had put another in but didnt help the brightness at all and i have not checked the second one i put in to see if that one went bad. could there be a problem somewhere that will damage the video tube to show just about zero on the tester. all the tubes were checked prior to putting them in or maybe that tube was not good in some way.
