HDM, or daugther board connections. The H drive is the same for all 3 tubes, so I can't see it being the CLM.

Hey Steve

Start with unplugging green convergence and stig yokes, see what that does.

Red and Blue are stable as a rock, the green is the only one to move.

Too much light here at the moment, will try some of your suggestions in a couple of hrs.

I know its not the daughter board as Steve soldered it directly to the HDM. Right Steve?

maybe corroded connections going to the deflection coil and als check the width coils on the hdm for solder cracks.
you probably looked at this first.

Correct, Daughter Board is soldered directly to the HDM.

Checked all the width coils, all are good.
Should I remove them, as I only run 1080p??? is that in the Modding Thread?? That Thread is so long now.......

Removed the plug from the convergence board, shaking was less, but not gone. Say 80% gone.
Thinking of cleaning the plugs and pins on the convergence board today, then see if the problem is fixed.

If it fixes it, then I will directly solder the cables to the convergence board.

Try to swap the H def driving between red and green (swap HDM plugs) and watch if the problem follows the HDM plug or not.

Ha Ha Tim,
Daytime here, too bright for my HT, so will happen later.

My boys are on schoool holidays, so we have been riding our bike down on the lake, then at the swimming pool for 1 1/2hrs.

Why not solder them??

More to come
