Here's some clown trying to show how to change a lamp...although the internal screw he undoes is obviously a closely guarded secret!
Like the dude in the comments says - it'd be better to have a vid of how to fit a bare bulb into an old casing as that's a very cheap option, and I doubt the casing needs replacing (?).

I developed at problem with My Pt Ax200u. It has been working flawlessly for years. There is 1100 hours on the bulb. I don't have any issues with a dimming bulb or flickering. I have had no warnings to replace the bulb either. The other day when I turned it on it stayed on for about 2 minutes and then the bulb went off and it went into standby mode. Yellow/orange light at the top and the fan is still running. It stays in standby mode for a few more minutes and then turns off, no fan and a red light at the top. The remote control and the buttons on the projector does nothing during this process. You have to unplug it and plug it back in to turn it back on. I have been successful twice last week turing it on and it stays on as if nothing is wrong.

I've read about a sticky iris problem on the 100u that sounds similar to my problem but nothing on the Ax200u. It looks like a easy fix with some WD-40 and a q-tip on the 100u. I opened up the lamp door on the 200U and of course it's different inside. I can't see the iris mechanism at all. Maybe I have to take the whole bottom of the projector apart?

Just seeing if anyone else has this problem. Do you think a new bulb will make any difference? I hate to spend money on a bulb if the projector is broken.

Wouldn't have thought it was a bulb problem. I've had mine stuck in orange flashing light mode just a few times from 3600hrs, but I don't think the orange light ever went out with the red light replacing it (the fan did turn off though), I had to switch it off with the switch at the back (I wouldn't have thought unplugging it would make a difference).
I've only been stuck in orange mode after I'd cooked the thing for many hours and turned it off myself (it never auto-powers off) and then tried to turn it back on whilst it was still hot and it only would go to orange mode.

In the options try turning SLEEP mode to OFF, maybe it's become tired...Other than that, I have no ideas as I know nothing about the things.
You could try my settings (which work best for me):
Picture:
Picture Mode>Normal;
Dynamic Iris>Off;
Light Harmonizer>Off;
Option:
Auto Search>On;
HDMI Signal Level>Expand;
Installation>Front/Desk;
Sleep>Off;
Altitude>Low;
Lamp Power>Eco-Mode

...I like Eco-Mode - rumoured to cause lamp flicker, but mine lasted about 2600hrs and I then reset the lamp runtime and finally just changed it after 3600hrs (the new lamp now seems too bright! And has exposed that a black screen has a slightly green tint). Maybe you live at high altitude and could change from Low (louder fan?)?...It's probably just a fault though.
...I've seen a newish one of these sell on EBay for £400 with a spare new bulb and not long on the original one - I wanted to buy it twice.
My biggest fault is the high-pitched (which some older people, 50+, can't hear) bulb filament (?) tinkling noise I get when my room/projector gets hot. The tinkling gets less as the bulb gets old and used to my 12hr solid gaming sessions (I don't use Game Mode, it's just a poorer image gimmick), so my new bulb is constantly tinkling/hissing after 30 minutes as my small bedroom soon heats up. Unfortunately, I'm too scared of spiders to open the window!
