    TCL 43S405 No image
    by m4a2t0t
    Backlights do come one but I see no image on screen. If I remove the LEFT side TCON cable I get an image on the left side of the screen and I can see the menus working (right side appears black/dark grey with a few large lighter grey bars), removing the right side cable and I get a black screen. It appeared there was a damaged IC on the TCON so I replaced it but there was no change. Is the panel bad?...

    Need help finding what IC this is!
    by Ross Kohler
    I'm working on a board that is used to control the charging for a lithium battery. I've tracked the source of the fault to this IC, I believe it's the charging controller but I can't find a datasheet to confirm that. Does anyone know what IC this is?

    The text reads:
    OAS
    TI 24I
    AV7V

    I struggled to tell if the 'I''s are 1's or just 'I''s. See image attached. Any help would be greatly appreciated!

    Thanks!

    Chinese windows tablet bios lock removal
    by nike486dx
    Long story short: bought a 8” generic windows tablet (based on Atom x5-z8350, bios chip model is Gigadevice 25LQ64CVIG, uefi vendor is AMI Aptio) for some experiments, and it came with bios lock! I dont have any decent 1.8v programmers at hand nor do i have knowledge in modding uefi firmware, so decided to play safe: dumped the bios with AFU utility, which i attach here. I am hoping to get it unlocked. Also included hwinfo screenshots with general information, the board itself looks generic without any markings.

    A1706 short PP3V3_S5
    by madjid911
    Hi friends,

    I have a macbook pro A1706 820-00923-A that won't start no signs of life, no liquid, checking the voltages I found PP3V3_S5 was shorted, I removed all the processor coils, but when I 'injects a voltage it is the processor which reacts, can you confirm to me that this is definitely coming from there please?

    I have 20V on the usb-c connector, and 13v stable on​ ppbus_g3h.
    I saw that a track had burned out on PPVIN_2V7NAND_LB after resistor R9350
    I injected voltage on L7660 pin 1 in short but only the processor reacts

    Thanks for your...

    BOSCH Microwave CFA634 error E1006
    by AlexVG
    Hi,
    I have Microwave BOSCH CFA634
    It runs, but after 10 -15 seconds stops working.
    Sometimes it shows error E1006.
    I can't find this error explication.
    Some people say it's communications error between main and display module.
    Probably somebody has an experience with this issue?
    Can you help me please?
    Thank you an advance....

    How do I flash bios to an Alienware M16 R1 AMD edition?
    by Arc717
    I am trying to downgrade my bios on my Alienware so I can undervolt & overclock my CPU, and overclock my ram. I need to get to bios 1.2.2 for this. Dell doesn't allow downgrades, and their bios file is an exe compiled in c++, so I can't decompile it easily. I am wondering if I can flash the bios manually using a usb flasher. I would like to know if this is possible, and if so, where the bios chip would be. I know flashers are pretty cheap and the bios chip is 8-pin. There are two of these chips only when I open the back panel of the laptop. I'm not sure if there are any on the other side of...

    Battery not charging in ASUS G532LWS Motherboard -> BQ24780S
    by cope
    Hi everyone,

    I have been working on a no power issue with my personal ASUS gaming laptop. It went dead a few months ago.

    Some history:

    Since then, I've found a blown mosfet on the GPU line which I replaced. It started up without a battery, then when I added the battery back it wouldn't start up again.

    As a result, there were some blown components around the BQ chip. (The BQ chip itself - BQ24780S, the low side battery mosfet (shorted), and a resistor -> all replaced)

    Now, with a new battery the system will start up and run off...
