On my Toshiba I tested both the 1.8s and 220s in circuit however I removed the signal board from the set so that I could work on my workbench.

One of them had a hairline fracture on it.

I had to remove my hyper module during the summer and I decided to remove it while the board was still on the plastic chassis it was more of a pain then it was worth.

So now I always remove the board to save myself the aggrivation.

The yoke connections on my set were on the far left of the signal board they are at the front of the board from the back of the set.

There should be colored marker marks on each of the connectors the red connector should have a red mark and the blue connector should have a blue one. The green wasn't marked on my set.

From left to right they are connected this way Red, Green, Blue.

It could be that the vertical output IC failed.

Unlike classic CRTs when vertical sweep fails a protection circuit kicks in to prevent the horizontal line from burning into the screen.

I don't know if this protection system just cuts off the color signals to the tubes or just shuts down the tubes completely though.

I'm sure lcaillo knows what this circuit does in these sets.

If thats not the issue I would search on the power board the filament voltage is derived from the flyback transformer.

Check the Horizontal Output Transistor first.
