To remove the CRT you must remove the video neck board.First of all you need to remove the VNB end of the ribbon cable. undo the ground straps from the chassis ,then remove the fan directly behind the CRT (remove one screw and it will pull upwards).Next you need to loosen the screw on the clamp that holds the VNB on to the CRT neck.When it is sufficiently loosened you should be able to pull the VNB assembly straight back and it will disengage from the CRT pins.If you are going to completely remove the VNB there are also a couple of other connectors attached to VNB assembly that must be taken off.
Do I have to pull hard to remove it? I have been trying to pull the cards back from the tube but I'm not able to move them at all. There is some black stuff, glue maybe, can that cause me problems putting it back?
I am a bit careful but I don't want to break the tube.
Forget the last post, I was able to remove the cards.
I think I know what the problem is, earlier when I moved the CAR-card I got the flickering, so my guess is one of the two connections between the cards. There are eight connectors in each and there is some sort of plastic holding them. Now I only have to figure out how to remove them.
I got the cards apart and put them back together again. Installed them in the pj and fired it up. I had it running for almost four hours and it look great. Earlier I could run it for no more than 20 minutes.
