Help stripping this polaroid lcd screen Options

[Beej]

A coworker and I bought these polaroid lcd hdtv for cheap on black friday at circuit city. I havn't seen one like it and i'm having a little trouble comparing parts to other lcd screens. Here are few shots of the inside.

We are pretty excited to try and build these projectors because they have a lot of inputs on the back as you can see.

This is what i found when i lifted the back of the inputs

i wasn't able to easily undo that thick strand of wires and i didn't want to force it so i just flipped it over upside down. It looks like there are ffc but i'm not sure if they will cause a problem or not. Infact i'm not even sure those are the infamous ffc's

Well you can't really see it from back there so here is a zoomed in picture. If this is going to be a huge problem, maybe i should just put it back together and try and buy some other lcd screen.

yep... big ffc problem right there, i think thats a 10pin, good luck figuring out how to extend that monster

sorry, that panel woul have been great with all those inputs

[davehtr]

if its a 10 pin all you need to do is get a 20 pin extension split it down the middle and bam you and your buddy have 10 pin extensions however your gonna need to find some 10 pin zif connectors

[dev.nicole@telen...]

I had the same problem.

The only thing you can do is to let it extend and solder with a mciroscoop.

Hi! I have the EXACT same problem as you! My monitor model and company is different, but i have the EXACT same cable- 0.5mm 10 wire FFC.

What my friend and I am going to try is to extend it with 10 pin FFC. Digikey (www.digikey.com) sells various FFC cables and connectors. I found a 0.5mm pitch 10 wire FFC there, as well as 10 pin connectors. I'm going to try to solder two connectors together to make a FFC extender, and connect the FFC cables from that. Here's a link:

Connectors:

Filter using 0.5mm pitch and 10 pins. There are alot.

FFC cables:

Find the cable you want, and remember the Digikey parts number. Type that into the DIgikey search to order it. I'm going to try to get this one:



Hope that helps a little.

hey!! i got the same problem i from mexico and my monitor is "mitsui" he he he but the monitor is the same please let me know how you fix the problem

[Cold Steel]

what's the model number of this polariod. I'd like to check the specs on it.
You should be able to extend that ffc.

I'll check it out when i get home tonight. i haven't made much progress on since my g/f bought a big screen tv..... guess i took a little too long to get the projector working.

Beej. Seriously. Put it back together an take it back to the store. I have this model and have attempted to use it in a PJ. The anti-glare is too diffusive and cannot be removed. Replacement polarizers don't work well at all. Cut your losses.

Are you sure you cant remove the anti glare? I have the same monitor and am right now attempting to remove it with the soak method. One question, on the back of the LCD panel, it is mirrored/silver instead of black. Im assuming I have to remove that as well?

This is the same panel I have. It is a re-branded samsung SVA panel and I and several members have bought it.

I am dead serous. Do not attempt to use any of the standard methods to remove the anti glare. I have used them all. The mirrored/silver layer is a polarization recylcler/polarizer. It will not come off with water and will be destroyed by paint remover. New polarizers will only give a partial image. Dont' be a fool. It's not a good panel for projection.

If you can improve the situation by some new or better technology, you have my blessing. Otherwise, get rid of it and count yourself lucky for finding out before you destroy it.

You are warned.

Alright! Thanks IronGecko, you saved my monitor. Now I still have a perfectly working TV. One question, I already bought another monitor online, supposedly easy to strip with no ffc isues. What I am really wondering is
-How do I tell if there is anti glare to remove (Only on front, or both sides)
-How do I tell if it is a coating or a film (Chemical or Soak method)
-What is the best way to remove the anit glare

Finally, how do I put all my inputs (COAX, AV, VGA, and possibly HDMI) into the VGA connection of the monitor? Would something like this be a good idea, assuming I dont bother with HDMI?

Anti-glare is easily identified by a low sheen finely-textured surface on the lcd. You cannot see your own reflection in an anti-glare coated lcd. An anti-reflection coating on the other hand will reflect everything, especially when viewed at an angle. However, the reflections will be dim and off-colored, frequently purple or green. Many higher-quality CRT televisions and monitors have anti-reflection coatings.

What type of anti-glare is not my specialty, but the general consensus seems to be to try the rag soak method first. The best method probably varies by panel and user and is relative to how badly things will go if things don't go well.

So I take it Anti-glare is a bad thing?

For that FFC problem is soldering a possibility? What does the ribbon cable connect to?

just wondering thanks,

Anti-glare is a layer to well... reduce glare!
As such, it cuts or diminishes the light that goes through the panel (it's like looking through sunglasses).
So the idea behind removing the antiglare is removing the sunglasses that your light is beaming through. But there's a risk. They don't call it extreme mod for nothing!

Soldering is a possibility, I believe, but a last resort
These are very small connections... You'd need a very fine soldering iron to do it and some magnifying glass.

I'd try digi-key. They still offer lots of connectors...




Best of success.
