Try changing the coolant in the blue tube. Contaminated coolant will give a halo look to the affected tube and you will experience difficulty focusing that color.Phillips/magnavox's blue is the tube most often affected with the contaminated coolant issues.

the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.

That is correct, if the lamp was bad then you will not see a picture at all. The fact that you are getting menu means the lamp is good and most likely the processor and light engine are also okay. Check other inputs to see if you have the same problem on all the inputs.
