Re: Who's got tricks for detecting a cracked LCD in a dead set.

5 second fix. Its at Walmart in the as seen on TV section. I did about 60 LEDs with 1 tube. Its about $5. Got the idea from Shopjimmy. He has it in one of his kits.

Thank you, seems it's available from ebay. I've just ordered some.

What's the UV adhesive you've been using ? I've been using Super Glue Gel but I've seen a little clouding caused by the fumes so am looking for an alternative.

Here's a side by side comparison. Notice the ring is off center on the one on the left. Welding helmet makes it way easier too. These things are bright.

I'm redoing it now. After several attempts, I just found a trick to get perfect alignment. I put the UV adhesive on, put the lens in place, then I turn it on and adjust the lens until I see an even ring of light in the center.

Now that i see the full white screen, i understand why you are not happy. I agree with tom66 though, it looks like an alignment issue with the diffuser, not different colour temperature of the replacement LEDs.

Re: Who's got tricks for detecting a cracked LCD in a dead set.

That's not different colour temp, that's a dirty/damaged or misplaced diffuser.

I'm going to open it back up then. I think it's because I didn't scrape the old adhesive off.

I'm actually not happy with it. I used LEDs from a 55 inch of the same series, because I didn't want to wait a month for new ones from China. It appears they have a different color temp. On a white screen, I can see the difference. I guess I'll figure out what they are and order them. This is why I prefer to replace every LED, even if they aren't bad. Takes a bit longer, but you get a Mich better result. It's going to a friend anyway, so I'll just redo them if he complains.

Nice looking job there. Congrats!

Success! 17 bad LEDs on 9 out of 10 strips.

Re: Who's got tricks for detecting a cracked LCD in a dead set.

I used to buy ones with broken screens, but now I've learned that when you say you don't buy broken ones, people just start giving them to you.

Never put it in the ad.
If someone texts me offering one, I just say I don't buy broken ones.
Otherwise, people will realise their broken ones aren't worth anything, and will make them appear good.
That's my theory, at least.

Speaking of that, just got a 32" Roku TV with a busted screen given to me...not bad. Paid $15 for a nice looking PN50A510P3f with sound and no display or backlights, new remote, power cord and owners manual in the original bag!

If that's all that it needs, indeed a good score!

I picked up a Samsung UN60J6200AFZXA with a busted screen for free. I hope I can find a unit with bad LED's or something and use it for parts.

Re: Who's got tricks for detecting a cracked LCD in a dead set.

My rules when looking at a broken TV:

If any parts are missing out of the TV it's a $35.00 charge to haul it off.

If I can't inspect/test it before taking ownership, or the screen is cracked I will haul it off at no charge. This includes dead units that won't power on or otherwise cannot be checked.

I only repair TV's that are in near perfect condition. Scratches and condition issues make it a parts TV automatically. After all why buy a used TV if it looks like hammered dog squeeze?

If it powers up and there are any problems with the display, or won't make any kind of a picture it's a $10.00 unit, period end of story. The power cord, working remote and owner's manual are worth an additional $2.00 each. A pedestal base, depending on condition is worth from $3.00 to $12.00.

I do not pay over $35.00 for any broken TV, regardless of condition or problems.

This strategy has netted me 4 broken LCD TV's this week for $10.00, two with display problems and two with bad screens, including a Toshiba 70"! Add another $20.00 in gas and that's what I have in them. I'm going to look at another one tomorrow for $10.00 with sound and no picture, a Samsung pn50a510p3f.

The way I see it, buying broken plasmas comes with risk no matter how good they appear, and I can't do this for entertainment value. If I'm not guaranteed a profit before I leave the shop it isn't worth it.

I picked up a 50LB6100 for $40 today. I drove about 112 miles round trip to get it. $19 in gas and tolls. Two hours driving. It was a nice drive through the country. Nothing wrong but bad LEDs (I saw a video of what it was doing). That's the farthest I've ever gone for a TV, but it came with the remote, stand, owners manual, and I forgot the box but he had that too. I have LEDs for it already, so it won't cost a penny to fix.

Anyway, I don't tend to do many TVs any more.

You can't give up on us man!!! You're in to deep!!!! Lol

Re: Who's got tricks for detecting a cracked LCD in a dead set.

I've only got one before.
It's pretty easy to spot.
Looking at an angle, you can usually see the LC damage. Pressing the screen lightly around the suspect area will show the LC moving around. (LC = Liquid crystal)

Re: Who's got tricks for detecting a cracked LCD in a dead set.

Here in the "Sunshine State" I try to take the TV out side in the bright sun to look for cracks but even then I still get a cracked screen. Trying to check for cracks in a TV that would not turn on.
