Cold Steel your pics look great and it sounds like your very pleased with the outcome, reading through your post about the FS mirror being the cause of your focusing issue(same info Dark Meat told me about mine) made me change my mind I now I think I will take a closer look at mine, but I really don't believe it's due to pressure because my mirror just slides down into position, we'll see what happens.

I pushed in the center of mine from the back side and it took very very little pressure to make the picture out of focus. That how I noticed the edges were down to tight on one side and to loose about halfway down the mirror edge. I hope you get it figured out.

ColdSteel,

So would you say that the picture is as crisp as it should be? Or do you still have a little blurriness?

One of the other techinques used by LL members is to move the FS mirror closer to the LCD. The further the mirror is from the LCD, the smaller the image is when reflected. If there is a flaw in the mirror, where the image is reflected, that flaw is enlarged and projected along with the image onto the wall.

By moving the mirror closer to the LCD, the image reflected is bigger, as it will be using a larger surface area of the mirror. Any flaw in the mirror, such as waviness, is less appearant in the final image, as it isn't magnified as much.

This will, however, push your triplet out further, so box and space are considerations.
For more informtion see arrik's plog, page 4, post #73. His pj looked much like yours, and then he modified it to move the mirror closer to his LCD.

Cheers,

Fulcrum


My picture is not at all blurry or fuzzy. It is very bright compared to my old style pj.

My Mrs says and I quote "This thing is just as plain as a plasma and just as sharp I'm so glad you built it" end quote.

She was very skeptical at first but the picture is worth a thousand words.

Fulcrum I'll do some reading on the link you posted. thanks. CS

ColdSteel,

I told my wife about your triplet poking through the wall. I told her that we could potentially do the same thing. She told me "No Way". But then again I haven't built my pj yet, so she may change her mind.

She has already exhibited a small change in attitude. When I first started buying components, she would say "What ever makes you happy". Now she asks "When are you going to build it... it will be pretty nice.!" So there is alway hope.

By the way, I'm glad your picture is clear. I keep wavering on if I'd do a folded design or not, so hearing that yours is clear is encouraging!

Thanks Fulcrum, My Mrs. was really really skeptical at first and now she is 110% all for the LL PJ. I now have to keep an extra bulb and ballast on hand (lcd too, mine i use) just in case it goes down. Besides that my Mrs. got to pick out a new theater room couch! smile.gif

What movies does she like, I can post a few pics so she can get a general idea of how they look.
I'm trying to learn my camera , I believe the batteries are weak and causing blur when I take them so I'm going to use my AC adapter and maybe speed up the shutter to catch a moving pic.

Hi all, just signed up. You won't have a problem if you hang a picture over it and remove the picture when you want to use it. This way when the lights are up and companys over, they don't know it's even there.

I have a rare Norpro stainless steel mixing bowl that I use for my reflector. I drilled a hole in the center of the bowl and put one wood screw in it to hold it to the plywood. It is quite simple with this reflector.

Great images and I'm happy that the wife likes the pj the whole looking out of the wall thing is freaky dry.gif makes me wish I wasn't in an apt to try it out. I do have one concern though, it's about the tape holding the mirror in place. I'm not sure how heavy your mirror is but I had alot of close calls with mines slipping and stuff so if tape works please use the strongest you can find and for backup use a mirror clip to catch it if it does slip.

Once again congrats.

Cold Steel
Thanks DM for the warning about the mirror, I really never thought about it just coming untaped. I may get some type of clip and secure the mirror a little better, just in case!:)

Cold Steel takes a plunge and pre-orders the Xbox 360 HD DVD player from Ebgames
and it comes with King Kong for free. It was $223.00 shipped with tax. The due date is scheduled for 11-7-06 but that might change to the 22nd I've read somewhere.
Now to wait and see how well it works.
Cold Steel
Ok peeps I've got my DVD player in and it's installed. It's awesome. It makes my image cleaner and brighter. I have it hooked staight through to the pj. The images I took were blurry. My camera or me is the culprit. I took good pictures once somehow I'm going to have to fix that. Some of the following are a little blurry but I assure you they are not in real life.

Here is a picture of my mirror frame which is now solid aluminum. You can see where I drilled and tapped the end for the old screw knob.
BTW- I found the aluminum at a local salvage yard for $16.00 but I had to cut it to size.




Here is a picture of the LL reflector mounted using a stainless steel light switch cover that has the large round hole in the center. I used springs under the cover with studs and nuts to adjust the distance. I don't have the reflector glued in place. It's just setting there.
After changing out the Norpro reflector to the LL reflector I couldn't tell visually any improvement in brightness. Maybe a light meter would have noticed the difference.

Cold Steel
It took me about 6 hours to complete the strip and install new lcd and removal of old lcd.
I DID NOT remove the antiglare do to the extreme thinness of this lcd.
I might remove at a later date but I doubt it. I can see through it easily so I figure light will pass through with plenty of brightness and it did.

Playstation 3 worked great. I plugged it to my PS3 prior to stripping. I didn't know if the lcd would strip so my $230.00 investment was up in question. Actually the Gateway FPD1975W stripped easier than I thought.
The only problems I really had was getting my big fingers into the small slot to remove the lcd connection.





This connection is glued on both corners. The glue removes fairly easy , it's silicone i believe. This picture show the grounding tape removed and the two glue pieces laying there after removal.




Maybe I should Start at the beginning.

Separating the housing. This is a little tough but it comes loose from the top best. I tried it from the bottom and then the top had to come loose first. Credit card didn't work. 2 flat screwdrivers worked good for me I was extra careful in case it had to go back because of FFC issues. There were none.
Slide the screwdrives together around the framework. Use a twisting motion to "POP" the clips loose.
The sides are a little tricky so try to do the top and bottom only with the screwdrivers. The sides remove with a little pressure after lifting up on the bottom.

Be careful not to pull the cables loose from the lcd. It's only got about 1.5 inch movement before cables rip.

The lcd and backlight assembly are attached together.

The lcd stripped but still has AG on it. The lcd glass is so thin.




I saved this to mount the lcd circuit board on.




I bent the edge 180 degrees to keep the edge from cutting the ffc ribbons.




I put black electical tape on the edge that i bent to protect the ffc ribbons.

The lcd controller with the back removed. This is the easiest mounted controller. It's compact and enclosed with nothing but wires coming out of it.

Cold Steel
My gateway lcd almost completely mounted . Just lacked folding the ffc ribbon over on the mounting bracket. I had to drill holes because the wood under the metal mounting was a shade to high. I didn't want to force the ffc ribbon 1/16 of an inch to compensate. I wanted the ribbon to lay free of any type of stress. I had to watch out for metal shavings from the drill bit and keep them cleaned up.







See picture below in post 75 on the finished mounting of the circuitry. Forgot to take a picture outside of the pj before installation.
Cold Steel
Cut this out and save it for your controls. I snapped the housing together and sawed it off.

I saved a piece of the metalic (silver) electrical tape to put it on the cable to ground it to the controller housing.

I'm so excited to see someone else has this monitor. I bought it the other day to put in my first build, a vertical with a beseler lens. I started a plog, but I've already changed the design and most of the components before starting. Anyway, I'm very glad to hear that there are no FFC issues. Are you satisfied with the brightness without removing the AG? I can't say I'm looking forward to removing it, and it sounds like it may not be necessary.

Is there anything not in your description above that I should know? Thanks for the great description of the strip.

Oops. I have the 1775W not the 1975W. But it looks identical, just smaller. I assume it will be the same to strip.

Do you have a link to your monitor. I can't seem to locate a Gateway 1775W. I found a Samsung 1775W.

It is an fpd1775w. Sorry for the confusion.

Here it is: http://www.circuitcity.com/ssm/Gateway-17-...roductDetail.do

When I bought it the other day, there was a $15 off web only special.

Let me know if you ever decide to remove the AG on your panel.

With your Gateway FPD1975W, how do you get your PS3 to display @1440x900? Or is your monitor scaling the signal?

I use the hdmi out with an hdmi to dvi cable. And changed my settings to 1080i in my ps3 menu.
It's fills the screen with nothing left off of the view.

I finally stripped my FPD1775W and can confirm that it is essentially the same as your monitor inside. The only difference is that my FFC cable is slightly different and had a little different connector, but it has no issues either.

I assume that you cut out the piece from the housing that holds the backlight to use to mount the circuit board attached to the LCD ? I'll have to do something a little different only because I want to try to use the backlight as a light table for film since I am also setting up a home darkroom.

Question: How exactly are you keeping the LCD in place? Did you flip the metal frame over (so that the LCD is facing up and the metal frame is facing down?) and then cut away the side with the circuit board? Or did you have the LCD and metal frame facing up and use the black plastic spacer to secure the LCD? Does my question make sense?

Your post was very helpful in stripping my monitor. By the way, when you referred to top and bottom, I was thinking of top and bottom as if the monitor were sitting on a desktop. I realized after a little while that it would be front and back the way I was thinking about it. After that, it was quite easy to strip.

Although I've never stripped one before, I agree that the glass seems VERY thin, and I'm reluctant to take the AG off too.
