    Notice to users of XGecu TL866II Plus / T48 / T56 / T76 programmers regarding BIOS backup file size
    by m1ch43lzm
    Hi everyone
    I noticed on the Xgpro software the BIOS backup files have extra bytes at the end when reading some chips, this is because the Xgpro software also reads the OTP region of those flash chips, and by default will append that region to the saved file
    Programmer models: XGecu TL866II Plus / T48 / T56 / T76

    Example: GD25LQ128D (1.8V), IC size is listed as 0x1000000 Bytes (16777216 bytes) + 0xC00 bytes, those extra 0xC00 bytes will be appended to the end of the saved file by default, resulting in a file size of 16780288 bytes
    There's also an extra OTP Secu.R...

    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....

    After updating motherboard capacitors, what to do next (Asrock K7VT2, SOLTEK SL-75FRN2L)
    by dragon3x
    Hi, I have some 32 bits computer motherboards that need repair, as they fail to
    power on.

    Here are some examples :

    (N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
    switching supply area).
    (N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
    than 6.3 V.)

    1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
    I replaced capacitors with aluminum-polymer.
    3300 microF/6.3 V. x 4 replaced by 3300 microF/6.3 V. (KYOCERA...

    AA and AAA battery charger capacitors?
    by slybunda
    hey all, iv got my favourite battery charger here which iv had for many years probably 15 years now or maybe even more. it still works good but thought id open it up to clean the dust out of it, lots of dust inside but now its clean and noticed 4 capacitors inside it and wondered if i should replace them.
    it has inside:
    2 x 47uf 16v caps 105c branded as Su'scon (lol sounds sus to me)
    2 x 470uf 16v LZ105c branded as G.Luxon

    not heard of these brands are they any good?

    iv attached photos of the charger and the board inside for an idea on the type of...

    Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock
    by sam_sam_sam
    I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

    This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

    After all of...
