good luck on your PJ MAN..
Yoder808
Got my L72S in...Looks Sweet so far.
Yoder808
Here is my strip, step by step...

First remove these two screws...
Yoder808
Then squeeze these and pull up...
Yoder808
Then you have this... Remove these six screws...
Yoder808
Then... I used a screwdriver at the bottom of the case (to stay away from the LCD) to begin seperating the two halves of the case. Then I continued around the case with a smaller screwdriver, being careful not to touch the actual lcd or frame.
Yoder808
Then you have this...
Yoder808
Next, I unplugged the speaker and control panel panel connectors...
Yoder808
Then I seperated the LCD panel from the rear frame...
Yoder808
Panel is out now...
Yoder808
Then I flipped it over, and disconnected the backlight connectors.
Yoder808
Then I cut this ziptie.
Yoder808
Then I pulled off this glue... at the lcd panel to lcd controller cable.
Yoder808
Then I disconnected this end of the cable. I would NOT reccomend it. It was quite hard to get back in, and I had to file little burrs on the sides the on male end off. I would disconnect the end on the LCD controller.
Yoder808
Then I took out the screws holding the Power supply and Controller on, and removed them. I believe there was also a ground wire here I removed.
Yoder808
These screws are very tight, I used needle nose pliers to grab the head and try to loosen them, then used a small phillips screw driver to remove them.
Yoder808
Then I removed the cover.
Yoder808
Then I pulled up on the tabs holding the frame/backlight assembly together, lifting the panel out.
Yoder808
The panel is now free.
Yoder808
Remove these nuts from the VGA connector to free the LCD controller.
Yoder808
The PSU free...
Yoder808
Ok, I am stripping my AG now, I decided to do the sand/stripper method. First I used some organic stripper, BIG MISTAKE... It didn't do hardly anything besides stink and make a mess. So now I got some Jasco Premium Paint and Epoxy Stripper, much better.... I will give a break down of what I got so far...

1.Masked edges of AG up to pixel line(hard to see) and edge connectors.
2.Sanded lightly with 320 grit(should have sanded longer, it is taking a long time to strip).
3.Appiled Jasco Stripper liberally over panel, wiped up excess.
4.Waited 15 minutes, checked, waited 15 more.
5.Removed and repeated 3 times.
6.Some AG is still on around the edges due to poor sanding.(Polarizer appears unharmed)
7.Still Stripping...
Yoder808
Ok, AG has been stripped, it took me 10 application, although 6-7 of them were on edges only using a q-tip. I should have sanded better, that was 99% of my problem. I have some goop(stripper I guess) on the rear side of my panel, and I was able to get most of it off with alchohol. But a tiny bubble formed on the polarizer/tac so I stopped right away. I pluged the panel in and it appears to be working just fine. I dont see any colorless spots, even where the bubble is(yet)...
comp_atkins
glad to hear you got most of the ag off.. any pics of the strip in progress?
Yoder808
No, i wish! My batteries were dead, and even if I had them, I was running around like a mad man most of the time, freaking out...so... I will take some post-strip pics though...

nice monitor smile.gif have the same kind, good luck!
Yoder808
Got in my reflector, Ikea napkin holder, it was in VERY good condition, but I polished further with Flitz, an aircraft aluminum polish we use at work. It increased it's reflectivness slightly, but it was like a mirror to begin with... Still waiting on lenses, light kit, and wiring kit. Ordered a Centerstage CS-1 for my video processing needs, $405.00...(retail $1999.99). It better beat the N6!

is the centerstage required thats kinda on the expensive side for me ... and i like this monitor.... is there a cheaper alternative for component to 1280?
rearden
Yoder808,

(or anyone else who knows)
Could you please tell me the external dimensions of the LCD? (so I can know the internal dimensions of the frame.)

I am starting the final stages of planning (hopefully) and want to start making the frames. I have 3 small live wires running around my house, so I don't want to strip my LCD (I am getting the Hyundai L72S) until the very last moment. But building frames for the LCD and fresnels is my first step. I am going to use the threaded rod design with a pro lens, vertical, AG removed.

Thanks.

The centerstage is not required, although, something, like a PC(for DVD's, or with a capture/tuner card for TV), or a Nextvision N6, Kworld TV box, etc. would be required. Also the CS-1 will not process HD, only up to 480p over component. If your panel will take 720p(the L72s wont) you can use a transcoder.

I show it to be 13 and 5/8 wide by 10 and 15/16 tall. Don't quote me on that, I have a crappy tape measure. smile.gif
Yoder808
Pro lenses are here(at LL), and all my stuff should be shipping very soon. I have made a styrofoam "blueprint" I will build off of, and the box doesn't look like it will be too big. smile.gif

your description "small" and "tight" do NOT do this part justice....

All is well (i hope. havent tried it since extraction)

wink.gif
Yoder808
Yeah, they are tight huh. I did pretty much what you did, but I had a tiny tiny electronics screwdriver to help. Also, a trick I use at work on really tight screws is valve grinding compound. It is an abrasive paste that is used for grinding valves on recip engines, but it also helps to "bite" the screw. Good luck man!

Well, it is out and i think the "minor damage" above is all this i sustained. (I HOPE)
Mikau
ouch! yeah cut sheet metel is wicked!
Yoder808
Dang, a DIY battle wound! I had a few from paint stripper!
Yoder808
Me and my buddy made a screen tonight out of wood, metal corner brackets and blackout cloth. It came out pretty sweet.
Yoder808
Yoder808


My friend Landree holding the screen, this is from the rear side.
Yoder808

My buddy holding the screen again, where it will go when my PJ is done. The screen is streched tight as a drum!
Yoder808
My styrofoam blueprint/full scale mock up. I was quite board. I WANT MY PARTS BRAINCHILD!!! :angry: (just kidding) But yeah, I really wish I had my stuff, I am so excited to see my results.


Yoder808
Just added a black felt boarder to my screen. Bought it in a 1"(i think) roll at walmart for about $1 per yard. Glued it on with fabric glue, its like Elmers glue. It sucks. I would use hot glue probably(low temp). Anyway, I think it looks freakin sweeeeeeet.
