Title: Elecronics guys: How difficult would this be to repair (LED TV)

My friends kid broke her TV.  She posted on Facebook, and the first response was "yup, no fixing that lol" from some dumbass who's probably never touched a soldering iron in his life.

From what little I know, the vertical and horizontal drivers have been damaged/disconnected in some way.  Before she shells out £100's on a new TV, what are the chances of a fix?

There is no fixing impact damage like that.  The glass is physically broken, so the only way to repair the television is to replace the panel, which generally costs more than buying a whole new television.

By the way: there's no such thing as a LED TV; the LEDs are just the backlight.

Ah sorry, not LED, LCD.  So it's screwed to the point where you can't open the back and look at the driver boards? I mean it's not like there's any damage to the liquid crystal... matrix?

Definitely looks like the LCD is damaged, you're better off looking for a new TV.

Have you tried to plug the hole with gum?

If that doesn't work, get a new TV.

I bought my 50 inch Westinghouse last black Friday for $350 and it looks every bit as good as my 52 inch Samsung I bought a few years earlier for $2,200.  TV prices are great now.

You know, I drove around several Targets for a Westinghouse like that which ended in complete failure... I didn't stand a friggin' chance. They were sold out within the first 15 minutes (I was told), so unless you were willing to sleep at the door of the store until it opened, you weren't getting one...

Deals that crazy are hard to come by, but I have seen 47"-ish screens on slickdeals.com recently in the low $400s.  I agree that flatscreens are dirt cheap right now compared to what they were a couple of years ago. It seems TVs drop to near black Friday prices here in the states just as football season kicks off.  I don't know if that holds true on your side of the pond, though.

I remember getting to Target at 7, which is when I thought the store opened.  Instead the store opened at 8, so I was an hour early.  That extra hour is why I got the TV.  I didn't mind the short wait for the great deal!

Yikes! I remember when my cousins' big screen CRT TV got Wii-mote'd. Didn't look as bad as that. Looked more like a stain on the screen more than anything. Luckily they are THE MOST Craigslist savvy people in the world, so they grabbed a free huge flat screen in the next few days flat.

Since you seem to be testing the waters with a replacement, I'd say go with a Samsung. I've had a few in my time and they're great, pure and simple. Whatever you do though, DON'T get a Vizio. They're America's #1 brand for a reason; they're cheap as $#%*.

Samsung certainly seems to be the company that is leading the pack right now, and I'd look for one if I needed a flat screen, but my folks have a 42" Visio that has been a champ for a few years now and we've mounted it to a couple of different walls.  It's been through the ringer a couple of times and perseveres. They don't have the track record of Samsung though. Just my 2 cents. :)

visio, just LG/goldstar for the most part
they are a rebadge brand, which means it could be anything inside (as was curtis mathis BITD)
note the curtis mathis sets were mostly NEC builds from a year or 2 back

and yes the LCD is cracked, its a parts set now

Heh-heh. Yeap... Maybe it has some decent capacitors in there one could make use of in something else. ;)

Ah, lucky. I consoled myself in the view that this "Westinghouse" brand probably isn't all that great anyway with a low contrast ratio, etc. but sounds like you're pretty happy with it, especially if you find it to be comparable to your Samsung. I like Samsung very much myself. I had a great 27" CRT from them in the early 90's. It was marketed as a 700-line resolution set, whatever the meant, but it had a REALLY sharp, high contrast picture - my SNES with S-Video looked fantastic on it. It did begin to suffer from poor degaussing issues when you had a pure white picture though... The top right corner would start to turn green, and it had to "cool off" essentially by going to a dark color or black (you could force this or wait for a scene change), then after it caught up in its degaussing, if you went back to pure white, it'd look OK again for a bit, but the process would start back up again, if that makes sense. Matter of fact, I have a Phillips/Magnovox 27" that suffers from this issue as well, just a bit.

Well, thanks for the second opinion(s).

I still think it's fixable, even given the cracked glass, because there's no bleed, and it's clearly displaying an image.  The way that the the image is distorted would indicate to me that it's an electronic issue.

There's three other things I would just sneak in at the end though.  I really hate the cuture of throwing things out for new just because they're tarnished and/or broken.  I would have thought more of you guys would be the same given our hobby, but whatevs, not gonna hate on you.

The second thing is, cheap as they are, she's a single mother, and though she's not really hard up, even a couple of hundred bucks in the back pocket can be a life saver in a situation like that.

And last one, I realise not everyone is like this, but I kind of see this stuff as a challenge.  If you get in there and poke about, it isn't going to make it worse, but you might get some benefit out of it.  Learning, fun, or even a new TV.  I guess I was imposing that view a little.

It's fixable by replacing the panel.  Period.

The way that the the image is distorted would indicate to me that it's an electronic issue.

The 'electronic issue' is the physical damage to the pixel circuits within the LCD panel.  They might technically be repairable, but only in a clean room and by machines.

Tell Donna to go get a used CRT for cheap.  Better yet - buy her a new set yourself and make her 'earn' it.  :twisted:

LCD TV panels have the driver circuits printed on the screen itself (a process called TFT)
your correct that the drive circuits are damaged, but the damage is the hole.
i wouldnt throw it out, i would look for another just like it that it can swap parts with

I'm not a wasteful person by any means. My main TV is 9 years old, my car is 21 years old, my living room stereo is from 1972. Most of my movies are on Laserdisc and most of my music is on vinyl.

But that shit is BROKE dude. I can't tell if you're trolling us or if you legitimately can't understand that.

Btw, I just bought a TV for my girlfriend's grandma last week for $150 at Target. 24", which is about as small as they come now. If you could actually find the panel for this TV it would cost way more than that.

I didn't understand, but Steve explained it great.  I've seen pics before and it always seemed like all the circuity was outside.

Thanks Steve!
