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

    Needless to say, I just lost some money. Couldn't see any screen damage at all. Set was completely dead. Got it home, gave the LEDs a test, and it had a crack right up the middle.

    I always ask them to turn it on. If it wont, I take my cell phone with the flashlight app and shine it at an angle to look for cracks. It dosent always work though. Thats why I love plasmas, cracks show up clear as a bell.

      I like that about plasmas, but nobody wants to buy them after I fix them. Flashlight didn't work on this one. Maybe I need one of those million candle power ones.

        How can people not like plasmas? I sold 3 of them to a family on 2/27/18 for $650!
        I will always have a plasma tv to watch, even if I have to store a few away.

          I think they're better, but people always say "Oh no, plasmas are dead, I don't want one of those."

            In OZ plasma been out for some years and now getting too old. I have a Panny and an LG waiting for fix but parts either hard to get or ridiculous pricing e.g $250 for a main board !! They'll be scrapped shortly if I can't get them going. Those that have them do like them and panels do seem to last OK despite half life warnings. Also here our electricity prices very high and people these days conscious of power usage. As for screens yes turn on or don't pay very much - I picked up a binned set recently hoping screen OK as I had same set new but with broken screen, got home turned it on and everything worked perfectly !! Ya can't win ! Or should that be lose ?

              I'm about to drive 100 miles tomorrow to get a 50" LG smart. Only because I know it's just bad LEDs and I have a complete backlight assembly for it and a buyer already waiting for me to find him something. Guy sent me a video, so I know what I'm getting. But I think I'm not risking much on dead sets anymore.

                Not.much different.here in the states.

                Nobody wants a plasma anymore it seems. I have 5 Panasonic plasmas all with bad SC boards. It takes time to troubleshoot and repair these just to sell for 100 to 150 max. It a a joke. Thinking of scrapping these myself as there taking up room and my wife's bitching about them.

                Sad day.
                Did I leave the soldering iron on?

                  I've no problem selling plasmas, I just call them flat screen TVs. If people ask I tell them they are plasma. But most don't care.

                      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.

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

                            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.

                                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.

                                  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.

                                    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!

                                      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.
