    Insignia TV-DVD : Model NS-LDVD26Q-10A screen problems

    Hi guys,
    I just bought this tv set from a friend who said it had a funny looking picture. I got it home, and plugged it in, and noticed at once that the screen has a problem. The top 4 inches of the screen look ok, but the rest of it is blurred and discolored,kinda looks like on old projection screen would if the convergence was WAY off. sort of. I think it has a shorted chip somewhere. I put a dvd in the drive and it has a blue background on the first few minutes of the movie, and the problem area is a light green from the 4 inch point down, and any movement in this area looks "shaky" , only way I can describe it. He was right about a "funny looking picture"! I have never seen anything like this before. Anyone with any insight on this I would appreciate your help/input, etc.

    Here is all the info I have on it at the moment:

    Insignia TV-DVD : Model number NS-LDVD26Q-10A 26 inch
    DOM 09E07-REV B 09E07A8604A Built-in dvd player, everything seems to work except the video problem, I haven't tore it down yet, too many other othere ones on the bench at the moment waiting on parts.

    I also am having trouble locating a schematic diagram for this unit, if anyone knows of one for it, that would be quite helpful.

      I take it these are not real popular sets!

          What is the model of the LCD panel in this set e.g. LGPhilips, ChiMei Optoelectronics, etc. It will be written on the back metal plate of the chassis (the LCD module.)

              Hi Tom,
              I have attached photos of the inverter, power supply, main board, and an over-all picture of the tv. I can't find any label on the screen, the inverter board is a samsung ss1260-4ua01, the mainboard is labeled dtv32(dams)m-9000,(there is a label on the tuner cover marked samsung dtvs205pl201a), the power supply is labeled mpo2008 rev1.6 I haven't diss-asembled it yet. Still looking for a schematic, but it seems the problem is going to be a driver chip on the screen itself. I turned it on again this afternoon, and noticed that with the menu up, the top was blue, and the bottom part was a bright red. I will try to get a picture of the screen tomorrow evening after work.
              Also, thanx for the reply, I haven't been an active member of a site like this for several years, and it is taking a bit to remember all this stuff.

                      Macbook 2017 with touchbar (A1706) won't turn on after removing the screen

                      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...

                      I have a older eddy current tester made by Olympus that uses interchangeable TFT-LCD screens. I have two devices that each take the same removable screens. One is an Olympus NORTEC 200D+ and the other is an Olympus SONIC 1200M EMI. I have searched the internet high and low for service manuals for these units with no luck. Both these units were used extensively by the US military for NDT on airplanes. The detachable screen plugs into the base unit via a weird non standard VGA connector. Buttons on the removable display are used to power the units on. When the power button is pressed the unit makes...

                      iphone XS turns off when press on screen.
                      by smic717394
                      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...

                      by vpower
                      I have this laptop: charging light is on when connected to the charger, when I push the power button you can hear the fans spinning for a three seconds, the keyboard backlight it turning on, the caps lock key is unresponsive, no image on screen. Only a couple of times it booted with image for a few seconds and then reboots to black screen. When it is frozen with black screen and lit keyboard, I can keep pressed the power button to shut it completely.
                      I downloaded schematics in this forum ( https://www.badcaps.net/forum/troubl...y/troubleshoot...
