This might be a little off the wall, but I was just given a really nice 42" LCD television because someone had accidentally thrown their wii-mote into it. Now, Most of the screen works fine, however, it does have a large spiderweb crack in the lower right corner. I've been wondering if there is any way to fix it. Since I got the TV free, and I already have a television (albeit not as nice), I've been wondering if there's any possible way to fix it. I'm not too attached to it, so breaking it isn't an issue, as far as reckless repair methodologies go... Here's the obligatory pic: Interesting, but not pertinent is that the Screen is driven by a gm1501 controller, whigh I can possibly reuse is I do wind up destroying the screen.
I would try disassembling it, because in most cases on lcds there is the very delicate actual panel, and then a thin piece of protective plastic. If there is, you can simply replace that. It all depends on whether the lcd itself is damaged, although in your pic it does appear to be (what are those wacky coloured lines?)
The lcd or rather the glass that all lcd's contain is broken in that picture. The reason for the lines is because the circuit paths going to the different rows and columns, in this case columns are damanged. Where the lcd would normally be competely black those lines are not getting the full electrical signal. Unfourtnatly there is no way to repair this lcd save of course replacing the glass peice. However it is not normal glass by any means nor could it be bought from any hardware store. The Glass itself has small ribbon connections coming off of it that connect to the LCD's driver circuitry. The LCD is toast, the only way you can repair it is to try to find the same exact kind somewhere else where something other than the glass is the problem. Such as bad backlight, or shot driver board. Otherwise what you have is a very large conversation piece.
The glass is definitely cracked. I'm aware that is is not normally possible to buy such a component at a normal hardware store. However, Where I work, I do have access to both a clean-room and some semiconductor fab resources. That stated, is there any way to etch a replacement sheet of glass? I would imagine that replacing it consists of the simple (if non trivial) task of getting some glass, cleaning it, Applying a conductive coating (could vacuum deposition be used?) then applying a mask (Photolithography?) and then etching it.
no. it's not just glass - it's a matrix of liquid crystal cells (and let's not forget the individual sub pixel colour filters) sandwiched between two sheets of polaroid coated glass. (in otherwords good f'in luck! )
We all wish we could repair and fix our busted and cracked LCD's but unfortunatly even with the resources some members of bit-tech have it is just so improbable that we say its impossible. Your only solution: Find an exact repalcement of the glass piece. Rebuild the lcd. Otherwise you could punch it more and light it up as a weird light-up doodad
I have seen a patent for TFT repair, involves putting material into the cracks then laser etching the grid back in. Bleh! Give your panel some time to see how bad the damaged areas get. Then make a new bezel that covers all the cracks up and leaves the undamaged area exposed, and use it as a smaller screen!
LOL.. get the extended accidental warranty,, its not like you put it through a blender like the blend tech guys with the video camera, But yeah you cant fix broken glass without melting it down and recycling it. Buy a new lcd panel and slip in there, but looks like a pricy piece of glass, my laptop replacement was $186 on ebay with a bezel, where as new the screen was $300 without a bezel. So your looking at a costly repair, so its like buying a referb to fix it, should still be less than a new tv, especially if you can get the glass used, from another broken tv like someone else said to do.
Tat is defineatly not fixable, as others have said. Just punch it some more and hang it on a wall as a cool lamp. When you touch it the colors will wary depending on the pressure you apply. just don't push too hard. If you do the LC will leak out between the layers and make ugly, black spots. (yes, i have seen LOTS of broken LCDs. And i always push on them for fun. it's quite fascinating )
heres another thought,, Why dont you sale it as it is on ebay as a parts tv, someone might be willing to pay you for the lcd controller thats in that. Also remove the lcd panel and find the model number sticker for just the lcd screen and google that to get an idea how much a new lcd panel will be.
I can probably reuse the controller (http://www.gnss.com/products/gm1501_ProdBrief_C1501-PBR-01.pdf). As I said in my first post, I know it's pretty much hosed, and there's no easy way to fix it. I'm probably going to gut it for the controller and get rid of the rest or hang it on the wall as a piece of psychedelic art. But Just because I'm interested, If I had, say, infinite funds and resources, how woud I go about fixing (not replacing) the screen. I said all that in my first post which, apparently, no one bothered to read...
replace the glass. people have only said it 90 times on this post don't get ****** w/ people when they answer your question but don't give you the answer you like..
ffs, i answered that. THERE IS NO WAY TO REPAIR A CRACKED LCD, NOT EVEN FOR SOMEONE WITH INFINITE RESOURCES AND FUNDS (well, maybe God could). YOU WOULD HAVE TO FABRICATE AN ENTIRELY NEW ONE.
I second what FOD said its not possible. Youd need a new screen unit, you could try contacting the manufaturer but it will cost an arm and leg
