Re: black vertical line
My guess is that there are loose solder points on the Matrix circuit. Best to resolder all points on board, especially the surface Mount ICs. If not familiar with soldering refer to service technician with the right equipment to do the job professionally. Toshiba Rear Projectors are common for this. Good Luck, Jus004

check if crt screen voltage correct (g2) try to adjust screen settings at flyback transformer and monitor if g2 response, some model if vertical ckt down monitor have black signal only can determine if screen adjustment knob in flyback transformer turn increase. vertical line appear.
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.
I can't tell you how to fix this set, but I can tell you that its not a "lamp" issue as this doesn't have a lamp. Its a 3 picture tube projection TV. the three tubes are in a red green blue format, and average about $175 for each one, not including the labor to install them. your problem, may not be the tube, but just a power supply problem, but there is a chance it is.

Yes worth repairing but not a crt problem. the crt's are powered by a high voltage transformer and sometimes it's caps that goes bad and in turn knocks out the crt's. but they are ok, it's in the high voltage line.
