I need some assistance in unplugging this wire so that I can remove the entire chassis for repair.  It is the WHITE wire in the picture.  The others has a twist off cap but the WHITE wire does not.  Any recommendation on this.

I've got an Akai pt4298hd, same as the samsung hcm4216w apparentely. I just replaced the convergence IC's and also had to replace a blown pico fuse. To do so I had to remove a few wires and for some reason forgot to label these two. Both of the wires go to one of the crt boards, but I can't figure out which wire goes on what connector (see attached picture). Anyone familiar with these sets? I can't recall exactly, but the connectors were labeled something like gt404 and gt563.

This past weekend as my daughter was playing wii on the Mitsu and it all of a sudden turned off, I have tried unplugging the set for a time with no results. All it will do is thw power light comes on for a few seconds, then goes out with no picture. Nearest service repair place is over an hour away. Any help would be greatly appreciated. Can email me at [email protected].

Thanks,

Scott
