I went to turn my TV on this morning and the blue was way way off. In the convergence menu I can only move the blue up and down not left and right. The TV also shuts off if I have the blue CRT cable connected in the back within 5 minutes, sometimes sooner. For now I disconnect that cable and the CRT board from the bottom of the blue bulb as a work around. (Yay yellow picture!) The TV now stays on for as long as I need.
What could be the problem. Willing to get my hands dirty.
