Hey guys. I'm new to the forum.

Last night, I received a Philips TV. It is the 347 H E10839 model. All the way around the edge is darkening and I was told that it needs a lamp replaced. I was also told that I can replace the lamp myself. I was given one of the old lamps and on the bulb itself is the following information: Top 188 L6 UHP 120W 1.0 PHILIPS 101958151 and then on the plastic "casing" that is holding the bulb is: PHILIPS UHP - LAMP 0652

1) Is the problem of the darkening truly from the lamp?
2) Can I replace the lamp myself?
3) Where can I order it (cheapest possible)
4) Any other information you are able to give, please.

Thank you for all of your time. I'm looking forward to being part of this community.
