    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 ?

    Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
    by Tynan Dill
    I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

    Upon bringing it home and plugging it up, it showed a standby light.

    I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

    The screen seems to blackout and stay black, but with a flashlight I can see the display.

    With my Playstation 4 connected via HDMI, and running a game I can hear sound.

    Assuming...

    Programming KBC IT8987VG ASUS TUF FX506L RT809F+PEB
    by araxnido
    Dear friends, I want to share my experience repairing an ASUS TUF FX506L gaming laptop motherboard: DABKXDMB8E0_F_BKXD. Boardview and schematic are available, as well as the BIOS and ITE ROM.

    When the customer brought in this laptop, it was initially dead; it showed no signs of booting for any reason. After hours of measurements, checking each stage, MOSFET, and seeing if there was a short circuit in any capacitor, I discovered a strange 0.7V leakage voltage on the 3V_S5 rail, particularly on the PL9 coil, with the board not powered on. There were 3V_LDO and 5V_LDO voltages, which...

    by jagg
    Hello friends, I have this laptop which would not turn on, I detected that the 3v and 5v source circuits were damaged and a 6 pin circuit in short, which I suppose are diodes, I'm not sure since there is no diagram, I removed this circuit and the sources and there is no longer a short, the new 3v and 5v sources were installed and the laptop now works, the problem is that I don't know what this 6-pin circuit is, I think it has to do with the battery, since the operating system does not detect the battery, I measured the IC pins and they go to these pins of the battery connector, does anyone know...
