    Another DGM L-2442WD

    Hi

    I recently acquired, and re-capped the power supply of, a DGM L-2442WD - five-or-six capacitors were bulging/leaking but I chose to replace all 15 on the secondary side.

    The first test of two hours was fine, but on the second day, after about eight continuous hours, the display began malfunctioning - fading to black/white/grey, pixelating, freezing, general psychedelic-ness (difficult to describe). Very disappointing!

    5v and 12v from the power supply appear stable - as far as I can tell.

    The old solder was difficult/impossible to remove and the new solder didn't seem to take very well, so I wondered if this new problem could possibly be caused by a bad connection on one of the new capacitors?

    Or could the smaller electrolytics on the main board be faulty? Or is it more likely to be something completely different?!

    As always, any advice would be greatly appreciated.

    Thanks

    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...

    UV solder mask - high temp resistent, recomendation?
    by myth77
    Can someone recommend any good UV solder mask? But i need a solder mask that will stand high temperetures. The thing is...sometimes i have a bigger cooper ripped from the board, lets say mosfet pad... i reconstract it with cooper sheet, then i "glue it" with solder mask...then i use UV light...and let it cool a bit. After, i try to clean the cooper of extra solder mask..and till that part all is ok. But, when i use a soldering iron to solder that pad/cooper...the solder mask gets weaker or destroyed and finally the pad is ripped again from the board .
    Is there any solder mask...

    BGA solder balls not connecting - help pls
    by petemanuk
    So I though in my spare time I’d set myself up repairing motherboards mainly pin damaged lga1151 sockets types.

    I’m using an achi ir sc pro rework station (gave up on my Achie ir6500 - don’t recommend)

    I’ve managed to get my rework profile somewhere in the correct region (after a lot of trial and error) to get the old sockets off and reflow new ones back on again, the problems I’m getting is not all of the solder balls are re-attaching when re-flow occurs. I know this because when socket is removed pads still look clean and have no solder...

    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....

    Solder not reflowing - what am I doing wrong?
    by sircastor
    I'm trying to fix a broken MacBook Air, and got a parts board to salvage components from. Following the suggestions of many folks here, I wanted to get in a little practice of using my hot air station (A Quick 957DW+) on the parts board so I know what kind of behavior to expect.

    For the life of me, I can't get anything done with this thing. I have tried multiple temperatures (from 210-425c), different air speeds, preheating the board (with the hot air, just warming it all around). I have applied what feels like excessive amounts of flux (Amtech V2-TF-559) and the solder on these components...
