What's wrong with my WG6100 and how can I fix it?
TIA

It's one of the transistors on the lower aluminum plate that has the 4 transistors on it. Most likely the 3716 that is furthest away from the tube, under the corner of the deflection board where the LV2000 board is. (Which is the lower left corner of the board, looking at it from the back of the monitor.)

A loose connection on the transistor socket is common on these. Pull the transistor, test it with a DMM (using the 2-diode test, google if needed). Then take a needlenose pliers and GENTLY pinch the socket contacts where it grabs the legs. That will tighten them up enough to make good contact again.

You can also take my 6100 guide and test the transistors from the plugs where they plug into the deflection board, with the 3 pairs of transistors unplugged from the deflection board. That will test the transistors, plus the whole path (connectors, wires, sockets, etc).

You should test them this way first, to find if there really is a bad connection, as the DMM will tell you. Just replacing the transistor may not fix it, and could make things worse. Download the guide here, and see the section about testing frame transistors:

 
either that or the transistor failed open. follow the andrewb guide procedure for testing the transistors at the plugs. if you find an open it's either the transistor that's open or broken wire connection. the wiring these use is solid core instead of stranded, if they get bent around enough times they break off.

otherwise all other suggestions are good. it's an easy fix if you have parts/know how.

Good job, you've earned these!

ok? I don't worship andrewb or Mark Spaeth, but when they have good information to share I think it's probably a good idea to utilize it.

then there's people that think I walk on water. I actually don't.

Who said Spaeth? Now we're getting into conspiracy territory. I only posted that as a joke because Andrew and texasfunnyhair already provided all the insight needed to help op.
