Where can I purchse new lens/lamps at for my Mitsubishi vs 5047?

No. It is shutting itself off after it finds something is not right in circuitry.

sounds like a bad lamp

pip moduel Call PTS 1-800-844-7871

www.tvrepairworld.com should have them. If you dont see it listed leave them a email they respond quickly

Tryi going threw video jacks instead of coax cable see if that works better

Unfortunately you will have to replace the convergence board in this unit. it has failed. this particular board regulates the alignment procedure that you are having issues with. replacing this board will fix this issue.

No it is not.
You need a professional.
Stop using the TV until it is repaired.
Call the manufacturer to find you nearest authorized service center.

That is a VZ3 chassis, similar to Mitsubishi models Ts-4545, Ts-5045, Ts-5545, Vs-4543, Vs-4544, Vs-5043, Vs-5044, Vs-5047, Vs-6043, Vs-6047 and has common failures in the vertical circuit, specifically vert Ic401 which is a La7845 which is usually caused by defective C402 100uf 50v and/or open 1.2 ohm 2 watt R510 next to FBT.
If not that check C268 off Q215 on signal board 22mf/50v and Ic200 on signal module Cxa2025s. However the vertical failure is more likely.

I had just put in about $500 worth of work into this TV to clean the color tubes of bacteria and other miscellaneous problems - They kept my TV for 3 months before bringing it back. It worked for 2 days and then everything went green, so they came back and took it for another 30 days before bringing it back.
This new problem could have been anything as simple as a tube to a circuitry problem. We decided to junk this Mitsubishi product. I have a 30 year old Curtis Mathis TV that I've never had any problems with (that's 3 times the age of the Mitsubishi).
We've opted for a new 50-inch Panasonic Plasma with the anti burn in technology. I will not buy another Mitsubishi product, or a rear projection TV of any brand after this experience. 

The part you are describing is actually the red picture tube, not a lamp. The tube will come dry and you will need to disassemble the lens assembly on the old tube, drain the coolant (antifreeze), reassemble the parts and seal on the new picture tube, fill with fresh coolant, install the new tube, reconnect all wires including the dangerous high voltage lead, then realign the yoke and entire convergence circuits. This is not something that should be attempted by anyone without experience. If you try it yourself and the seal is not working perfectly, the coolant will drip down on your main boards and the set will be ruined. If you slip while lowering the new tube in the chassis there is a good chance you will crack the tube's neck, and that tube will be useless too.
