    The voltage across the large capacitor is 321.9V

    The IC has this part number DA 29CK and GMO 565R

    That voltage is good. Unfortunately I can't find any reference to the part numbers of the SMPS controller.

    This monitor came in this morning with no power. This is Samsung SyncMaster B2330; I have checked the fuse and others things all look fine no bad capacitors.
    I have checked the voltage going to the signal card CN802 but all comes out 0.00V that show that there is voltage going there. The IC871 and F911S all are fine.
    Please help me on this one?
    I appreciate all your kind help.
    Thanks.

    First of all, while the pictures are fairly good, there is one mistake that makes things more difficult than necessary. This board has a strong orientation -when the CCFL connectors are toward the top of the picture the component identifiers are all right side up. While I can read upside-down, it's not something I prefer to do.

    Now onto the real problem.

    1. What is the voltage across the large cap?

    2. There is a large heat sink at the top of the picture. The IC on that heat sink is the SMPS controller. What is the part number?

    Samsung UE55JU6800K half screen dark
    by Chrissygizmo
    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...

    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. ...

    Samsung UN55J6200AFXZA Splash Screen Comes up, goes out, screen flashes one time and won't turn off
    by JunkmanJimbo
    Samsung UN55J6200AFXZA Splash Screen Comes up, goes out, screen flashes one time and then tv won't turn off.
    No picture. No sound that I can tell. Backlights are on and have been checked. Flashlight test no image on screen. I replaced the Eprom chip hoping that was the problem but nothing changed.
    Please help. Thanks in advance!

    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...

    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...
