    Smug line on Polaroid TV FLM-3734 LCD Screen

    I have a 37 inch Polaroid TV FLM-3734. There is al smug line on the screen that does not move. On a light colored picture you can hardly see it. On a dark color picture it can bee seen more. On the orange screen it is located in the bottom left quadrant. Any ideas on how to repair it or can it be repaired? Enclosed are photos.

      Noise in voltage supplies that is in beat with the line hence the noise lines in theory. Go and check.

          No noise, no beat. It did have a buzzing noise before I replaced the caps. The buzzing noice was on the same panel as the caps. The caps were for lost of picture/sound.
          Thanks

              thats a bruised panel.something hit it.
              live with it or replace panel.
              the swirls are an artifact with the camera.

                  This seems to be a common occurrence nowadays it really makes you appreciate how relatively bulletproof CRTs were.

                  If you elbow a CRT you're looking at a bruised elbow not a broken screen .
                  Elements of the past and the future combining to make something not quite as good as either.

                      I received this from an older couple that took very good care of it. They said they hardly touched it when cleaning. They also said the smug started by a spot which grew into line. If this is the case can it be fix and how? Thanks everyone for you help so far!!!!!


                      note: The words on the first photo are not the problem I am having. They are moving on the screen. The photo stop the movement causing it to look that way. The last photo is a good example of the broblem.

                          I've seen similar marks that 'grow' on laptop displays. Generally caused by a bash to the display, they can also come from bad design where there's pressure on the back of the display that, over time, distorts the plastic diffusers in the display.

                          The only way to fix it is to replace.

                              So what would get replaced? The whole display (LCD) or the plastic diffusers?

                                  Samsung LH82QENELGC/EN Help needed - Static line on screen
                                  by Kiberge
                                  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...

                                  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...

                                  by almarhum
                                  Has one here really gone through fixing laptop screen vertical line(s) by repairing/replacing its Embedded DisplayPort (EDP) cable, so would recount and share the complete steps of the process here now?

                                  As most, if not all, believe the laptop screen vertical line(s) caused by defective Embedded DisplayPort (EDP) cable which slipped and passed through either laptop screen hinge but post here is asking help to elaborate definitively the useful, real knowledge of repairing in the most complete, correct way, esp. can decide/determine whether the cable can still be fixed or must be re...

                                  Hi,

                                  I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...

                                  LG OLED 55EG920V Black Screen with one line
                                  by fibcom999
                                  Hi guys, I have aquired a LG 55EG920V for very small amout of money.

                                  I have jumped the Power on, DRV_ON and 3,5v pins just for the screen to show a black screen with a green line offset to the left.

                                  Connecting everything together, shuts the tv off automaticlly after a couple of second( LG protection?)

                                  Tried with a spare MB and the original, both the same results.

                                  But if i unplug the 12v rail to the tcon or the larger LVDS to tcon, the tv turns back to the one line and dosent shut off.

                                  Could this be a tcon issue or something...
