Hi All!
Okay, I have a CF-29 with some weird blemish(kinda like a fingerprint but the surface of the screen is spotless) on the LCD screen(not the touch panel) so I was wondering if the screen from a 28 can be used on a 29...I doubt it can but I thought I'd ask anyway.
Thanks!

No it will not be the same lcd panel
The screen brightness on the cf-29 is 100 nits brighter I think
Do you have a cf-29 mk-2 that has the mark on the lcd?
Alex - 
 
Nope, nada, nyet, ain't gonna work...
 - 
 
 Ah, well, I didn't think it'd work...and it is good to find out before I take them apart
     
It is the mk-3 model - 
 
Are you sure it ISNT a fingerprint on the screen protector? Perhaps some noob replaced the screen protector and got his dum thum on the sticky side?
 - 
 Thats a really good thought, definitly worth checking out

No! its a burn area of LCD. I have a couple of that LCD thats I've changed Mostly I've notice on CF-29 with 1.3ghz unit.

Yeah, I separated the LCD from the touch panel to be sure and it is on the LCD.
So my next question is...Is a 29E screen compatible with a 29H? - 
 
 Yes I believe they are but I would try to get a screen off the newer MK4 or MK5s those (minus the touch panel) seem to be the best luck with not having spots. The MK2 (CF-29E) screes have been terrbile for burn marks for me
 - 
 
 
Yes all the lids /screens are interchangable
I have problems with the touchscreen panels,mostly mk4's the screens have been fine, even on my order model mk-1's

Yeah -
This is an unfortunate side effect of the quest for ever-brighter screens; instead of the single CCFL at bottom or one at top & bottom, these guys have 4 tubes running horizontally. With the tubes at top & bottom, you can keep them away from the light diffraction panel (a big thick piece of clear plastic), so if one of the tubes develops a "hot spot" type failure (caused by mercury vapor accumulating on an arc burn), it still isn't easily visible on the screen.
With the 4 tube arrangement, two of the tubes are right in the middle third of the diffraction panel; if one of those tubes gets a hot spot, there's no place for the heat to go except into that piece of plastic and... melty spot which looks like a thumbprint behind the LCD substrate.
The rotten part is there's no good reason those panels couldn't be made in a modular fashion so that the light generating portion (the source of 5% of the manufacturing cost and 95% of all LCD panel failures) is separate from the LCD substrate; it's just the overweening greed of manufacturers making SURE they have product turnover and millions of pounds of poisonous waste waste annually be d@mned.

I could not agree more. - 
 
 If you think that four is excessive
The Panasonic 12" PDRC LCD Monitor has seven inverters, and seven backlites arranged horizontally to get it's 1200nit brightness

 Good lord... you could put a fresnel lens in front of that & use it as a PROJECTOR... like that lame-O "blueprint kit" in the back of all those comic books & Popular Science... ONLY THIS TIME IT WOULD WORK!!!

 Yah It was not really truth in advertising
I liked the x-ray glasses advertisements myself
Never bought them , thought about it quite a bit, now they could have would of been useful if they worked

Are the CF-28 / Cf-29 screens compatible?
