Chances are good the Blue CRT is bad. Especially if you see thin lines going diagonal across the screen. Sony has not had CRTs available for these for quite a while. They have been requiring that the CRTs be sent to them so the can mount a new CRT on the Lens/Coupler assy. Here's the rub, it cost approx 300.00 for rebuild for each tube and because of the age on the set all three shoud be done. Other wise you will have a color imbalance not to mention the chances are real good that the other two will also have the same promblem sooner than later. In short, I would not invest the money into it. The only way o really find out is to get a Local servicer out to comfirm what what the cause is. If you call 1-800-222-SONY, they can help direct you to one.

If after the Flash Focus™ feature has been performed, the colors on the FLASH FOCUS screen do no line up (converge), press the FLASH FOCUS button on the television to begin the cycle again. If the colors on the FLASH FOCUS screen continues to appear misaligned, service will be required .
