    Emachines LE1938 - replaced cap, now white screen

    Hey everyone,
    I have an Emachines LE1938 monitor (19") and it was doing the blink thing. I replaced the one bulging cap I had in there. Blinking problem is gone, now I have a blank white screen. I have searched and done some reading on the same model, and some different, threads. The ribbon cable is plugged in as it should be. I've checked and double checked all the connections. I have no idea what can be wrong with this thing now, but obviously it is something I did because it worked fine, apart from the blinking, before I "fixed" it.

    Obviously its not an expensive monitor but I really like to be able to repair things and keep using them, than to just throw it away and buy a new one.

    Here are some pics...
    Pic1 - Red circle is the cap that was replaced (same type, just different brand - tho the diameter was noticeably smaller) Green circle is correct (I did it) Orange circle is where I am unsure if the connection is right. My husband likes to come and poke his nose in what I'm doing like I'm incompetent or something. Grrrr So I didn't see how they were, originally, when he disconnected them. However, I have tried these wires both ways and have the white screen either way.
    Pic2 - Other side of board. I am sure its ugly, I am not a pro.
    Pic3 - Video board
    Pic4 - Ribbon cable plugged in. Does it matter if this has the original tape on it? It won't re-stick after taking it apart. I used some blue painter tape since it doesn't have an insane amount of stick but enough to keep it in place.
    Pic5 - White screen, but i notice looking at it from the site, there are lines (you can faintly see in the pic) I am not sure if that means anything.


    I hope this is sufficient info. Thank you in advance to anyone who can offer me some insight.

    Thanks

    A white screen suggests you might have a blown fuse on the t-con board (picture 4).

    That t-con usually has a SMD fuse. A good fuse will measure less than 1.0 ohms on your multimeter.

      Thank you for your reply. Is it logical to think that a fuse blew between the time that I unplugged the monitor, took it apart and replaced the capacitor to the time I plugged it back in?

        I don't see an option to edit my above post, so I apologize for the double. I am worried, since no one has replied, that it may have seemed like I was being a smarty pants before. It was an honest question, I really don't know. I am sorry if it was taken that way.

            White screen repairs
            by harp
            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...

            samsung galaxy ao2s very temperamental after screen replaced
            by Chrissygizmo
            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. ...

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

            ThinkPad P15s Gen 1, NM-C931 REV 1.0 touch screen replaced only works in UEFI menu
            by Yehuda170
            original screen was BOE NV156FHM-T07 with On-Cell Touch screen I²C

            replaced with what was in my stock, which is IVO R156NWF7 R2 which is also with On-Cell Touch screen I²C

            now touch screen works perfectly in UEFI BIOS menu & boot menu. but not working in OS, tried windows & linux too

            with original broken screen i can see in device manager touch screen in human interfaces

            but with the new screen it's not showing in device manager

            is it lenovo blocking it? is it driver missing?

            I²C is a headache

            Sharp LC-65Q620U White Screen
            by EazyBone
            Another TV topic!!
            I got this sharp TV that when I first plugged it in it showed the sharp logo and then went to the input screen. This was about 30 seconds and then it showed white screen. Now I can't see anything but white screen. This has a separate TCON and Main.

            The TCON is getting 12V and several parts are as well but the VGH line is only .5Volts which I thought is totally incorrect.

            Am I on the correct assumption that the TCON is bad somehow if I'm only getting that voltage or is there something else I should check?...
