    LG Plasma CTRL ROM 42V7

    Hi. I'm desperately looking for a source of ROM file for a PDP42V7 PDP (Non- vzb). I think the file I need is 42V73DNCS1 or 42V73CS4AD.

    The original ROM was 42V73LA2A, I flashed a file I had in but got blank display, though on board test patterns were fine. Biggest problem I have is that I have to remove the IC to program it.

    Any advice?

      Thanks. I think I already have that one which appears to be for the KIT, but I've got nothing to lose here apart from some time so I may give it a go. The problem is that this is a cheapo TV I've had for ages, the PDP is a 42V7 but the boards are not the same numbers as in the LG service stuff that I have. My boards are Y-SUS 6871QYH045D, Z-SUS 6871QZH049B and CTRL 6871QCH066H. The CTRL ROM was 42V73LA2A dated 051210.

      Wish I'd downloaded more of these files while I had access to the LG site

        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...

        Lenovo ThinkStation P520 BIOS file needed
        by Forest79
        Hello,

        I got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
        The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.

        However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)...

        NT955XED (Samsung Galaxy Book2 Pro - 15.6) BIOS dump file Request
        by Citymin
        Hi all,

        My Samsung Galaxy Book 2 Pro 15.6-inch laptop has no display and won't boot.
        The charging red LED lights up, but the charging screen doesn't show any indication.
        When I press the power button, the blue LED cycles on and off three times, then the screen doesn't turn on, and the device won't boot.
        (I've tried removing the battery and resetting the device, but the issue persists.)

        NoteBook Model name : Samsung NT955XED-KK51G(Galaxy book2 pro, i5-1240p, 15.6inch AMOLED)
        PCB model name : Venus2-15-5G(REV1.2), Venus2-15 ADL NPC

        TONGFANG "GM7TG7P" Bios Password Problem?
        by traxformania
        Hello,

        I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).

        But today it's not accepting my password. I'm %100 sure i'm entering the correct password.

        I'm trying to reset my bios without success.

        I tried :

        -I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries...

        PS3 CECHC03 60GB YLOD Troubleshooting
        by Woodsworth
        I have a post on psx-place for this but thought I'd try here as well in case anyone has experience or the schematics or any kind of help. Here's the original post from psx-place:
        START
        Hi, so I bought a YLOD Fat PS3 as I wanted a repair project and thought it would be a good way to get experience. I was able to solder to the RX, TX and Diag pads on the COK-002 motherboard and was able to get external access and retrieved the codes. I haven't powered it on beforehand so these should be the last ones. I did try to get internal access immediately after but kept getting scopen response...
