    Re: Vizio 26" VW26L Flickering white screen

    Its not going to be easy I dont know how you find them!!
    What is no on U11 and confirm no on UP5.(cant find it again!!!) dont know if its a mosfet or a VR. perhaps Budm can tell. Are we limited to none voltage tests on this? or can it be connected up?
    If it can be powered what is voltage at each side of the fuse and V33V and V25V with respect to ground screw.

        Well this is the first one


        But having read its title I have little idea what it does. ( I havent read the description)
        -Tomorrow job. Hope you have better luck with the other part. (not that I know how we can test them - again relying on Budm.

          If that P/N is correct, that link show that it is just a Dual-Op amplifiers.
          At this point I do not know what else to suggest.

                  Selldoor, just a follow up on the fuse now that it's back together . the fuse tested 11.95v on one side and 1.4v on the other side

                                  It is a minefield but I think its a 1.5 as well
                                  Digikey do not seem to stock
                                  so mouser http://uk.mouser.com/ProductDetail/C...oEzVC0ag7W4%3d

                                  Whilst they seem to have some that number has been marked obeslete at cooper-busman and the now have this one.


                                  So you can try other outlets using those part numbers if you dont want to use mouser

                                  We sometimes suggest other types of fuses but you have space constraints.

                                          Tom66, Before I tore down the tv again I checked the fuse reading again. How it's reading 11.95v both ways. I assume that is a good reading.

                                            White screen repairs

                                            To ask here... I have few devices with white screen problem, actualy nokia 2220 and some fuji? camera, and try to understand what is common problem to cause that issue.
                                            Yes, both devices work everything else probably ok, I mean, I hear intro melody and keypress click sound, DTMF tone, power on off... all ok.
                                            On desk is nokia 2220 slide, and I check all screen connectors and components arround it, measure voltage drop, but all looks ok. I suspect on slide flex cable, but it look ok and white screen is not interupt while flexing board, pushing conectors, and sliding up down. In attachment...

                                            Viewsonic VS16217 strange problem - white flickering screen on power up
                                            by domu
                                            As per subject, on power up display shows no image, but white
                                            flickering screen. Strangely, it only happen after power was lost
                                            when it was on. After power returns - white screen only, but if
                                            disconnect power for 12-24 hrs, and connect then again monitor
                                            works normally.

                                            Any clues how to go about it would be greatly appreciated.

                                            Vizio TV M50-C1 reboot cycle and static on screen
                                            by spice_disc
                                            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...

                                            Lenovo Thinkpad X1 Gen 10 - Flickering Screen
                                            by Ado02
                                            Hello everyone,

                                            We recently replaced the OLED screen on a Lenovo ThinkPad X1 Gen 10. After about a month, the replacement screen began to flicker. Initially, updating the Intelยฎ Irisยฎ Xe graphics driver resolved the issue for about a week. However, when the problem recurred, updating the driver again had no effect.

                                            The flickering only occurs once the system reaches the Windows login screen. Interestingly, if we disable the Intel GPU driver or connect the laptop to an external monitor, the flickering stops. We have tried installing two different replacement screens,...

                                            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...
