    Samsung LE-40M87BD Screen Bleed?

    Not sure if this is screen bleeding or what but in certain parts the picture can be seen through it

    have tried a hair dryer from the outside just in case it was condensation or the likes but makes no difference neither does touching the effected area

    any ideas? or just a bad panel with damage?

    also there appears to be no impact damage anywhere, lady i got it off said the usual "it just went like that"

    This is a common issue with this model and is unrepairable.

    Also, I feel it's necessary to remind everyone that people lie, you cannot always trust them.

        Re: Samsung LE-40M87BD Screen Bleed?

        I think it's related to a defect in the bonding between the layers of the LCD but TBH I've never had one myself, just see it now and then on this forum and on ebay.

                Check READY in service menu... if set turn it OFF... From standby, Info Menu Mute Power on remote.

                    No further ideas then, other than to troubleshoot rest of PSU by heating/cooling etc.

                      Re: Samsung LE-40M87BD Screen Bleed?

                      heat makes no difference to the psu or main board

                      i've had a similar issue previously from a 32 inch model and found it was the main board causing reboots when powered up so i'm going to say it's the same here another bordeaux model too

                      if i remember right it was when the main board went cold it would happen (from startup usually) no idea about how this is seemingly getting cold when it is in operation

                      not worth my time or money to replace the main board

                      may try a rework on it later, some flux and a heatgun see how i get on

                              found out it is the mainboard unsure whether it's caps surrounding the processor or the processor itself

                              If i let the fault occur then heat around the processor the fault disappears until cold again and continues endlessly rebooting

                                just to follow up here with the fix (not for everyone)

                                decided against the heatgun and went for the oven instead

                                desoldered the shield hiding the processor/IC's give it some flux and wrapped the rest of the main board in some tin foil (made some foil balls to rest it on) let it bake at gas mark 4 for 15-20 minutes, let it cool and reassembled

                                TV no longer turns off after ammounts of time, left it on for 6-8 hours last night with turning it off and on in between and all seems good now

                                again probably not to everyones taste but easy way to fix cold solder joints (which i'm guessing was the issue)

                                  Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
                                  I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...

                                  Hi , I've recently replaced the screen in my Samsung galaxy ao2s, at first it wouldn't even turn on, it had the charging symbol on the screen when plugged in but the green circle wasn't going around to show it charging....
                                  Ive eventually managed to get it on and working but it's very temperamental...

                                  The battery icon always reads as 50% , when the phone goes into lock screen mode i sometimes can't get the screen back on unless I plug the charger in to get it to light up, also it keeps putting the camera app on.. u think it could be something to do with the side buttons. ...

                                  HI guys!

                                  I've got a Samsung LH82QENELGC/EN with a problem and need some advice and I hope this is the forum to use?
                                  I'm from Norway so I'd like to apology in advance if my description of the fault is kind of simple or the names on the components are way off. 😊

                                  the TV is powering up, working as normally and picture is all good, except a 1.5-inch-wide vertical line of snow/static across the screen.


                                  This TV is a Signage Display/Public Display version and it's been used at my work for 4-5 years showing commercials 24/7. The fault occurred when...

                                  by Ryan.man
                                  Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

                                  My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

                                  This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

                                  Hello everyone,

                                  This is my first post after browsing this wonderful treasure trove of knowledge for many, many evenings. I've decided to learn how to fix these things, properly.

                                  My patient is an A2338 Macbook Pro M1 (late 2020).

                                  It had some corrosion around JT710 and JT700 caused by liquid spill, as well as against the protective barrier around the USB-C chips UF000 and UF100. So I took the main board out and cleaned it with a toothbrush and alcohol, then with alcohol in an ultrasonic cleaner. Cleaned the touchbar flex connectors as well. The board looks...
