    Solder joints on heat sinks matter?
    by jm1234
    Hi,
    solder joints on heat sinks - how much do they matter? Could poor joints on heat sink cause issues if they are not properly joining to hot ground?
    I'm looking at power source module of Panasonic plasma TV and I see many of these having visually poor quality, but could they matter? In general I would guess no, but I saw a video where someone was stressing out the importance of tightening the screws when fastening the power source board specifically for the ground to be connected properly.
    Thanks

    EMMC programmer questions
    by EazyBone
    Looking to up my game a little bit, but these programmers seem a bit daunting.

    Trying to get a device for EMMC repair, and it's very difficult to lookup all the words to find if I'm on the right track lol.

    Trying to reprogram EMMC on Sony/Hisense mainly but would like to hit a few other brands.

    My question is would either of these work? And is there a specific card reader I need for TV emmc? There is like 10-40 additional pieces that I can get but not sure what I actually need for my application only.

    I may do eeprom as well. Can someone point...

    Can I fit a UE49MU6470 Diffuser into a UE49NU7100K?
    by fuus
    Evening all,

    Long time no post!

    I have a UE49NU7100K here with the classic melted diffuser and damaged backlight from getting too hot. Locally there is a UE49MU6470 available which I could pick up to replace the melted diffuser. Would this work or am I missing something? They look like the same style of backlight.

    If this sounds good, where is the best place to buy a new backlight? Will I regret buying from Aliexpress?

    Thanks in advance for any help

    Dell Latitude 7420 2-in1 display error strange lines
    by ongobongo
    Hi guys,
    I have another problematic laptop here, a Dell Latitude 7420 2-in-1 with touch display.
    Motherboard is Compal LA-K371P Rev.3.0.
    The laptop has a strange display problem, see attachment for more details. This problem is not windows related, as soon as you start the display has those lines even in the Bios. If i attach an external monitor, the lines do not appear there.
    I was able to get my hands on a second display, but the problem persists, so it seems to be something different.
    any ideas?...

    Need a HP 255 G8 (HPL51 LA-L021P) BIOS
    by mitchw
    Looking for a BIOS for HP 255 G8 (HPL51 LA-L021P).

    The main problem is that the laptop will crash while booting to OS. Will crash even on booting from USB, like a Ubuntu or to a Windows 11 installer.
    Before junking the board I would try the new BIOS if it does anything.

    Thank you!...

    How do you trim a BIOS file?
    by survivalbloke
    I downloaded a BIOS file from Lenovo and once I extracted the actual BIOS from the executable, it is 16MB in size, but my IC(Winbond 25Q80DV) is only 8MB in capacity. I have read you can trim the BIOS file with a hex editor but I can't find any instructions on specifically what you will remove.

    Samsung UE55H8000SZ with TCON BN41-02112A
    by michdundee
    Hi all,
    I'm facing a issue... hope you could help me. I have a T-CON board BN41-02112A from Samsung 55inch Curve TV.
    I have just only 2 status blue LEDs ON since LED3 is off. I have tried to test some test points but VON is NOT OK very close to 0V. Is there someone that can help me on the debugging the issue? I'm supplying the board from an external 12V voltage source. ​
    Thank you in advance.
    BR,

    A2141 Screen replacement. Boots screen freezes on Apple Logo 1/3 status bar unless connected to second monitor.
    by abajor
    Having this very weird issue.
    The owner of this laptop complained about screen being intermittent when opening and closing, and has been using the laptop on a thunderbolt video connection since the screen failed.

    I swapped with a working screen from an A2141 waiting for parts.

    The Os exhibits this weird behavior where it boots to to 1/3 the status bar, then it makes the boop sound. It's at the log in but for whatever reason the desktop isn't loaded.

    The laptop boots fine into recovery mode. I updated from Monterey to Sonoma and the laptop still has...
