    Samsung UN58TU7000F no picture
    by Yanleb
    I have a Samsung UN58TU7000FXZC (same as UN58TU7000FXZA, just the Canadian model) with no picture. Backlight is on and sound is coming out just fine. Just no picture.

    What is frustrating is that there's no voltage test point and no component labelling of any kind.

    What I have found so far:
    1. No voltage at pins 91-94 of the 96 pins connector CN1300 (marked 1 on the picture). This TV set has no T-CON board. The 96 pin flex cable goes directly to the right (when facing TV) lower panel board. Itself is linked with another flex to the other side.
    2. Voltage...

    Where to find a very small fpc connector 0.3mm between 2 pins ?
    by corrize
    Hello, I search this connector (oxydated).
    It's a fpc zif low profile connector. It come from camera sensor, it is very small : 0.3mm between 2 pins.
    I ordered 2 from Aliexpress called « 0.3mm pitch » but one was 0.5mm between 2 pins and the other 0.6mm. In fact « 0.3mm pitch » seams to be the pad width and not the distance between 2 pins.
    I can't find it. The other websites like mouser dont show the datasheet, and I can't check if it is 0.3mm between 2 pins ?


    Do you know how to find this connector please ? What is the exact name for find it ?

    a dark pin on connector of RTX 3080
    by paparazzo79
    Hi guys.I got myself used RTX Aorus Xtreme 3080.I have not yet tested it, due to waiting for PSU with 3 PCI-E cables and GPU holder.
    However today on sunlight I noticed that on one of the connectors one of pins is in darker color then the rest of us.
    Paranoia hit me that maybe card is damaged.
    I don't know if you can see on pics (on pics looks like one of the pins is missing, but is it not, it is dark and covered with shade).
    I tried to zoom in but get blurry pics.
    If you can not see,I will try to picture it again.
    What to do now?Could it be potential issue...

    Asus FA506IV - AL116 no 5V and below
    by aico60
    Hello Guys,

    When I first bought the laptop, I knew that it was been worked on.
    When I received it, I saw that there were mosfets missing, however there were 3.3V on the Power button, as well as 5V in the USBs (I have tested with USB lamp). I tried to power it on just to see if the fans would spin. They did not.
    The audio chip was heating up, so I removed it (there were still 5V and 3.3V available)
    Once I received the Mosfets, audio chips, IC, etc., the 5V rail disappeared, as well as 3.3V and 1.2V. The main rail (19.5V rail is OK).
    Haven't measured others...
