This link allows you to download the manual. if you need it; http://www.usa.canon.com/app/pdf/projector/lv7215_7210_5210_manual.pdf page 41 especially worth a look page 43 gives all details for lamp replacement if you still think is the problem. Almost certainly the problem is to do with overheating - which is either a bulb problem or a malfunctioning fan. See if the fan runs when you turn it on and check it is clear. Hope this helps :)

Possible cause is overheating.
Do you hear the fan working?
What happens when you use the lowest level light output?
Does it run longer?
Also possible cause is a faulty temp sensor.
AC wire connection may not be firmly pressed in socket.

It sounds like it is overheating. Are the fans all working? If so, try opening the casing and blowing all the dust out with a can of air from Staples/Office Depot. If the fans aren't working you may need to replace them.

THe slanted line suggest interference of some sort with the video signal. The projector has a number of protection circuits built in. Usually there are temperature indicators as well. I am not familiar with your specific model to know whether or not there is a temp light. If not, the LAMP light may be indicating a temperature problem. If the ballast was the problem, the lamp would not light. The ballast has no effect on picture quality. It is possible that the main power supply has a problem in its output section. A bad filter may be allowing some AC current to flow on the DC line. This can show up as lines in the picture. Also, that oscillation can also cause the computer control circuits to misinterpret the current status and may shutdown the projector as a protective measure. Without seeing the unit and taking measurements internally, I can not state for sure.
Try cleaning the fan area and filters to eliminate a temp problem and update this with your results.
I will check for a service manual to provide additional possibilities.
