    4921QP1046B fixable ?

    I have two IPM ICs 4921QP1046B, pulled from the Z-Sustain board 6871QZH060B. Interested to fix them, but it's covered by the material which is not transparent, tried my best to remove but still not successful. The parts are still hidden.
    Anyway to remove and clean it inside so I can see all the parts ? or service manual for the module ?

    A1312 (27” iMac 2009-2011) A1407 (Thunderbolt Display) A1316 (Cinema Display) Display Black Screen Repair

    Problem

    This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

    Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
    by acedogblast
    This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

    There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

    Samsung UN65JU67ODFXZA Version TD01 Schematic and Parts List
    by Mark D
    The TV is a Samsung UN65JU67ODFXZA Version TD01. I replaced the power source board and the TV is now working, but I decided to try and troubleshoot the old board to fix at the component level. Trying to get a schematic and a parts list has proven to be an issue. Trying on my own, I can't tell you how many times my Norton security has flagged sites as "malicious". I ordered a service manual from ServiceManuals.net, paid $16.99 and got 66 pages of everything BUT schematics and component parts list! Can anyone steer me in the right direction? Some of the surface mounted component parts...

    Hantek 365 Remove screen on startup
    by Maxpower3
    every time I open the tool, I have the screen that appears
    and I am always in a hurry to use it so I click and it automatically sends me a link to the manufacturer.

    It annoys me lol.

    2 solutions to remove it.

    Either you remove pic.bmp and it no longer appears so no more links when clicking.


    or else you can modify the exe to remove the .bmp


    hope this helps users...
