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

The Sony diagnostic routine for 4 blinks indicates it to be a vertical deflection problem.
Did you see a solid horizontal line in the center of the screen prior to it going out? If so, that is a tell tale sign for vertical problems.
basic sony reset below
The STANDBY light will flash if the television detects an issue within the television. Some of these issues can be resolved simply by following the steps below to reset the television.
Turn off the television.
IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
Turn on the television.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center

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.
