    The way that it fades like a black cloud makes me think its the panel.

          That's exactly in the middle, probably points to a T-con issue and for $20, worth a punt.

            Ive had a few sets with exactly that fading symptom. Turns out the tab-bonds were the problem with them.

            Made the usual temporary repair with foam-tape which have survived months now.

            One however, refused to be fixed!

              Looks like panel to me. $20 might be worth it for the parts though.

                The main board for this model TV looks similar to the Westinghouse LD-4655VX, which is known for having a shorted out LED ribbon cables. This TV seem to have LED back-light out along with a possible bad ribbon cable for the LCD screen or the panel is bad.

                  Thanks all. I'm going to pick it up in an hour. I'll at least give it a shot. And I'll post me findings

                    It's the panel IMO. Not backlights. If backlights were bad it wouldn't be a sudden cut off. $20 though does get you a good main board hopefully.

                      Re: possible purchase Westinghouse led 40 split screen

                      well I just picked up the TV. The guy had it on a wall mount he said and he took it off the wall mounts put it back on The stand and he could not find the original stand screws so he went down to the local hardware store and bought some really long threaded screws and he ran them through the TV on the bottom I think he probably hit a ribbon cable.
                      Did I leave the soldering iron on?

                        Re: possible purchase Westinghouse led 40 split screen

                        Ok here's what I found. sure enough the screws protruded through the ribbon cables from the tcon to the screen. Whats interesting is that I had an old t-con board from a Samsung that the spacing in size was correct so I swapped the cables Beautiful picture now.

                        this Westinghouse has a sharp panel in it and Samsung ribbon cables work worked. They were a little longer but I improvised.

                              Lol thanks. I'm surprised it didn't short the panel or the tcon. IT has a decent picture but I'm not very impressed. The contrasts are over saturated. Seems to be an LED thing. The sharp 80 inch is that way a little as well. Whites are blue and the menus are very basic. Cannot compensate for the LED white balance.
                              Did I leave the soldering iron on?

                                do the LED backlight cables run inside the LCD screen?

                                    I hope this model doesn't share the same common failure like the LD-4655VX. The LED backlight cable short out to the metal bar of the LED stripe due too heat.

                                      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...

                                      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...

                                      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...

                                      I'm currently trying to diagnose and fix my Vizio TV (Model M50-C1). I've tried a number of different basic solutions, but I'm trying to determine if my issue is currently a failing panel, T-Con board, or main board (or something else entirely) and whether or not it is worth my time to fix it. Details of the issue and what I've tried are below as well as why I think it is either a bad panel, T-Con board, or main board.

                                      The Issue: The TV will be on and working fine but after the TV is on for ~5-10 minutes the screen will freeze (with sound continuing) until the TV reboots itself. While...

                                      i have an ipad pro 9.7" (1st gen) A1674 where i replaced the screen, but never attached the screen to the frame/chassis (glued down) due to the ipad being previously dropped so the new screen would never fit in the frame properly. so i need flex/bend the chassis to eventually fix the new screen in properly. so i temporarily just applied blue tape around the edges of the screen to keep it in place. when watching videos with the ipad the screen started flicker, so i though maybe the new quasi cheap amz screen i purchased was going out. so i disconnected then reconnected with power still on,...
