CRT TV HV RED WIRE
I amd attempting to remove the chassis from my old TV. I can unplug all
wires except one. This is the high voltage heavy insulated red wire running from the HV transformer to the back of the cathode ray tube where the is a large round rubber insulator. I do not seem to be able to pop off either end of the wire. At which end should I attempt to remove it without damaging the set? Alex |

CRT TV HV RED WIRE
After discharging the residual high voltage stored on the picture tube
by taking the hv connection to dag ground, simply lifting up the rubber boot and pressing in on each side of the metal connector clip will allow it to be removed off the tube. |

Thanks. I got it off. This will be the 4th time over the past dozen years that I have resoldered components on this 32 " Sony TV. I am having doubts whether I can fix it this time - let alone get all the plugs back where they belong. But I will try. Alex |

Alex Once you begin to troubleshoot the set, post your findings and maybe someone here can help you out with some repair tips or advice. All or most of those plugs should be different sizes and colors. Usually the color of the plug matches the color of the jack, and the size is always an exact fit. If it doesn't plug in easy enough, don't force it - it may be backwards. In some sets the plugs have a letter or number code printed on the side with a matching code on the boards near the jacks. I anything is not marked you should use masking tape or little white stickers to make labels so you can find where each plug came from. Good Luck. |

Well, my repair solder job did not cure the problem and may have introduced an additional problem. There is now a predominance of green in the picture so human faces look green which cannot be eliminated by varying the hue. So I now have two problems. The picture still looks good, however. Thanks for the tips. Alex |

Thanks for the tips. My guess is you either made a solder bridge somewhere, or you swapped two plugs when putting it back together. Keep at it, you'll fix it eventually, just be careful. |
