About TV Repair: How do I disconnect Anode connection from Circuit board?
I'm trying to disconnect CRT from main circuit board on my 27" Sony Trinston? I did disconnect all the wires except the Anode Connection wire (red color). I tried to pull out from the power source on main circuit board, not from CRT. It just did not come out. What do I have to do? Is this wire a clipped or not? |

It should be a wire or pressed steel sprung clip, which fits into what is called a 'cavity connector' on the CRT bowl. For most CRTs, removal requires that the edge of the 'poppy' is gently lifted from the bowl, until you can see the actual metal contact, and then by pressing on one side of the contact, with the tip of a thin screwdriver shaft, until it bends in enough to relase on one side. The other side can then just be lifted out. BEWARE. Much lightning lingers in that cavity connector, and can do for a very long time after the TV was last powered. Do take care lest this lingering lightning smites thee ... Arfa |

You are doing something wrong... g Go back and *look* carefully at the connector at the tube. This is not rocket science, you'll figure it out. Trying to 'disconnect' at the other end will only break it. |
