I recently moved the TV to another room (it got bounced around a bit). The picture was fine initially. Over the course of one week, I lost the picture. First, colored lines began showing up at the bottom of the screen. Then it just disappeared. Now all I have is three curved lines (red, blue, green) arcing across the screen from one bottom corner to the other. The audio remains intact.
If I need to access the software, I do not have any image making this rather difficult. Any suggestions? Thanks...

The color wheel is your suspect.......usually whines a bit
when bad. In a quiet room, you can hear it when the TV is powered on or off. It spins at 9,000 rpm ( wears out the bearing).
The lamp will not exhibit those symptoms....
the tv got dust when placed out say u need to clean the inside of the light engine, the lamp too but be careful u must use only methylated spirit with a new soft dry bristle brush caution if u touch the lamp with your hands u will shorten its life. the color wheel inside the light engine needs to be cleaned the same way too make sure u do not spill any thing in the components and of course the tv must be off nand left to dry before restarting
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 have seen this symptom a lot recently. There is a 9 volt regulator on the small signal board, and the output voltage on this IC has dropped down to about 8 volts, which causes that symptom. Replacing that regulator should cure your problem, and when I make a housecall for a set like that I charge $150, although I hear that the average service center charges a lot more than that. I also believe that it is never a good idea to leave a projection TV on all the time, so whoever told you that has no idea what they are talking about.
