    Repair protective glass on large HD LCD TV


    I was throwing some trash in my apartment complex dumpster and saw a very large LCD TV. I couldn't pass up the chance I could fix it and quickly noticed the only physical damage I could see was the outer glass was cracked and not really to bad even though the cracks run the screen no spider web.

    Got it inside and cleaned it up and plugged it in, the LCD screen is perfect!

    Now I have a less then a year old LG 47" 1080p HD 240Hz true motion LCD TV/Monitor.

    So far minus the cracks which while watching with the TV a little higher then it should be looks great.

    So my question is would anyone have any ideas on how I could remove the protective outer glass without damaging the LCD (there is a 1/8th gap between the glass and LCD surface) I have thought about taking the whole thing apart and then remove the glass from the frame or just being really careful and remove the glass and then just buy a sheet of plexiglass or regular glass and epoxy it in place.

    If anyone has ideas on how best to remove it? or what to use to replace it? Or just remove it and leave it off?

    I will provide pictures if that will help both with image and without to best show the damage and that the LCD is perfect from what I have seen, guess I should run it though a test screen video since I can hook up a USB HDD to it and watch movies I could use a large test pattern to check for dead pixels.

    the model is a 47SL80 if anyone want to see what it is.

    All I know is even at a repair shop its going to be cheaper then what the very nice large LCD is worth. I would like to keep it under 100 though as I need to replace the remote and get a real stand or wall hanger for it.

    Can't wait to get the cable for my laptop and plug this computer up to a 47 in. screen gaming will have a whole new feel.

    You would need to remove the panel to get to the protective screen. If you are good with electronics, you could do it. After you remove it, you won't need to replace it, and if you did, don't use regular plexiglass, it will distort the picture. The protective screen no doubt has optical properties to make it completely transparent. I'll see if I can get you a manual with disassembly instructions if you are interested. A Guy

    That part is actually 1 piece the front bezel, ACQ74811407 Cover Assy Looks like at retail the part alone is around $500! Have a dremel tool? The manual doesn't have disassembly instructions (LG Service manuals suck). Here is the exploded view if that helps. Your best bet if you can disassemble yourself is us a demel tool or such to cut out the protective sheild and just leave it off. Most LCD TV's have the LCD panel right up front. But then again, I've see many a Wii'd LCD panel, ooops, crack, $$$

    Part# 300 is the assy, the far left piece is what's cracked, but it's an assy with the bezel.

    Well I could take it apart myself no issue there at all. From that picture and from checking the unit itself that glass and bezel seem to be just glued or epoxied onto the plastic. Unless the dremel has a glass cutter gutting the protective screen wouldn't go well.

    Looks to me like those long sections on part 300 might be foam or something that makes the adhesive contact. I can say with ease that the glass could be removed easy once the rest of the TV is apart and which would keep the LCD safe while I remove the glass. The biggest issue is there is a 1 inch black band around the edge and that has a small oval hole for the remote sensor. I was thinking just replacing it with a sheet of real glass without the black trim paint.

    Thanks a bunch for the exploded view will make tear down much easier. My next issue will be finding a place I can work with it and the only place I can think large enough will be on my bed and just hope I can finish the job in a single day.

    I found http://beta.searspartsdirect.com/par...&shdMod=47SL80

    and they have the front assembly for a reasonable price. They also carry the base and the remote. I am still looking at other places but sears seems to be the place to get the parts I need.

    I took the back off and can see they epoxied brackets to the glass to hold it in place. So I can find a way to get the brackets off the glass and then on a new piece I can replace it or just get it from sears already together.

    That was a good price on Sears, the distributor site I looked at had it at $500. A Guy

    Yeah I can't beat the price sears has for any of the parts, The base unit is really cheap and they have the remote so I don't have to order one from some unknown web site.

    Now that I can replace parts and know legally that its mine under Florida law spending 125 - 250 or so is well worth the price for such a great TV.


    Thanks very much for the break down image that helped a lot in figuring out what I can and can't do to fix it. It will be a while before I get it fixed but when I do I will remember that Just a Guy helped me have a TV I couldn't afford.

    Funny that someone threw it in the trash for just that. There are things called "warranties".

    Nope, physical damage not covered by warranty, and almost all extended warranties. You broke it, you fix it. Guess the original poster has lots of $$, or didn't know the panel wasn't broken. Either way, macgyver2's gain
