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.

You have a problem within the light engine. This a hugely expensive. If the set is not too old you could contact Sony and see if they will help you out. Otherwise it is not eceonomical to repair

Had this problem bout 2,3 years ago...it was fixed in about 5 minutes with the help of this article
Tonight I have to do this fix again..the blue lines came back about a week.
I strongly urge you to save the web page locally on your hard drive or print it out and place with the tv manual....

Dot problem in Sony DLP TV caused by bad light engine (optical block)
Its costly part and needs qualified TV tech to fix it.
