    P5B-plus d3-d7 post code

    Hello,
    I got an Asus P5B-PLUS motherboard witch wont give me picture. The CPU fan is working, the led on board is on but the picture on screen never shows up. Graphic card works 100%.
    When I inserted pc analyzer it gave me these codes:
    D3D3 without any RAM memories,
    D7D7 with RAM memories (in all slots, few different modules,together or solo).

    AMI (D3)DMA controller #1,#2,interrupt controller #1,#2 disable. Video display is
    disable and port-B is initialized. Chipset initialize/auto memory detection about to
    begin.
    another PC analyzer code book
    Starting memory sizing next.
    None of these have any information on D7D7 error code. Any help will be appreciated. Thank you!

    Re: P5B-plus d3-d7 post code

    this type of error typically indicates ram or memory controller issues. usually, u'd check for bad caps around the dimm slots and then check the voltage regulator for the ram. then the northbridge. maybe northbridge needs a reflow or the mosfet powering the northbridge went bad.

      Checked the fets, they seem fine. I replaced the two caps near DIMM slots, same result. Reflowed the northbridge - same results. After replacing one of two caps near northbridge pc analyzer outputed 4040 error.
      Preparing the descriptor tables next.
      Preparation for virtual mode test started. Going to verify from video memory.
      CACHE memory on and about to disable A20 address line.
      I'm guessing this is a step back... :/

        Re: P5B-plus d3-d7 post code

        actually, its fine. for modern ami bios (i'm assuming this since its an asus board) based boards post-2002, its starts with the D post codes which is early chipset and ram, bootblock and bios flash initialisation. btw, the d7 post code means:
        D7 - Restore CPUID value back into register. The Bootblock-Runtime interface module is moved to system memory and control is given to it. Determine whether to execute serial flash.
        now u made it all the way to post checkpoint 40, which is almost there to mid-late post, so its an improvement. post code 40 means this:
        40 - Detect different devices (Parallel ports, serial ports, and coprocessor in CPU, … etc.) successfully installed in the system and update the BDA, EBDA…etc.
        this may indicate a mobo onboard device has failed and could be holding up the boot/post process. u have to find out which one is the culprit. note: it is possible for more than one onboard device to be bad and holding up the post process.

        btw, most post code booklets that come with post analyzer cards have obsolete info in them that pertain only to pentium pro, 486 or earlier bios. for 2002 or later pentium 4 or athlon xp boards, the post code booklets shouldnt be trusted. i have a post card and the post code booklet that came with it wasnt helpful at all for troubleshooting the modern boards i had.

          Thank you, all this info is much appreciated. Can you give me an idea on how to find the culprit? I'm guessing looking for heated components, maybe alcohol trick.

          Do you have better table of bios post codes I could use?

            Sorry for double posting :/
            I'm reading what northbridge controls (communication between CPU,GPU slot (AGP or PCI-E)) and RAM. Could it be that I fixed the northbridge but in the same time broke RAM? Since I used not so exact cap to replace original ones.

              Another update:

              I have just returned the 470uF 6.3V (witch I replaced with 470uF 16V before) back to the board. And now my analyzer displays an 6060 error code.

              Code 6060:
              The DMA page register test passed. Performing the DMA Controler 1 base registar test next.

              DMA page register test passed. About to go for DMA #1,verify from display
              memory.
              At this point I tried to power it with graphic card witch gave me 6F6F error code. And playing with RAM modules and another graphic card result me in error codes 9898 and for the first time D4D4.

              Code D4D4:
              Uncompressed RUNTIME code.
              Chipset Initialization/auto memory detection about to begin. Check SIMM for
              mismatch.
              Returning to real mode. Executing any OEM patches and setting the stack next.
              Code 9898:
              Clear all Interrupts.
              All Interupts cleared.
              Control to optional ROM
              Optional ROM control is done. About to give control to do any required
              processing after optional ROM returns control.
              No info on AMI 6F6F code.

                  Re: P5B-plus d3-d7 post code

                  Code:
                  A0 - Check boot password if installed. 
                  A1 - Clean-up work needed before booting to OS. 
                  A2 - Takes care of runtime image preparation for different BIOS modules. Fill the free area in F000h segment with 0FFh. Initializes the Microsoft IRQ Routing Table. Prepares the runtime language module. Disables the system configuration display if needed. 
                  A4 - Initialize runtime language module. 
                  A7 - Displays the system configuration screen if enabled. Initialize the CPU's before boot, which includes the programming of the MTRR's. 
                  A8 - Prepare CPU for OS boot including final MTRR values. 
                  A9 - Wait for user input at config display if needed. 
                  AA - Uninstall POST INT1Ch vector and INT09h vector. Deinitializes the ADM module.
                  AB - Prepare BBS for Int 19 boot. 
                  AC - End of POST initialization of chipset registers.
                  B1 - Save system context for ACPI.
                  00 - Passes control to OS Loader (typically INT19h). 
                  2A - Initialize different buses and perform the following functions: Reset, Detect, and Disable (function 0); Static Device Initialization (function 1); Boot Output Device Initialization (function 2). Function 0 disables all device nodes, PCI devices, and PnP ISA cards. It also assigns PCI bus numbers. Function 1 initializes all static devices that include manual configured onboard peripherals, memory and I/O decode windows in PCI-PCI bridges, and noncompliant PCI devices. Static resources are also reserved. Function 2 searches for and initializes any PnP, PCI, or AGP video devices.
                  38 - Initialize different buses and perform the following functions: Boot Input Device Initialization (function 3); IPL Device Initialization (function 4); General Device Initialization (function 5). Function 3 searches for and configures PCI input devices and detects if system has standard keyboard controller. Function 4 searches for and configures all PnP and PCI boot devices. Function 5 configures all onboard peripherals that are set to an automatic configuration and configures all remaining PnP and PCI devices.
                  While control is in the different functions, additional checkpoints are output to port 80h as a word value to identify the routines under execution. The low byte value indicates the main POST Code Checkpoint. The high byte is divided into two nibbles and contains two fields. The details of the high byte of these checkpoints are as follows: 
                  HIGH BYTE XY 
                  The upper nibble 'X' indicates the function number that is being executed. 'X' can be from 0 to 7. 
                  0 = func#0, disable all devices on the BUS concerned. 
                  1 = func#1, static devices initialization on the BUS concerned. 
                  2 = func#2, output device initialization on the BUS concerned. 
                  3 = func#3, input device initialization on the BUS concerned. 
                  4 = func#4, IPL device initialization on the BUS concerned. 
                  5 = func#5, general device initialization on the BUS concerned. 
                  6 = func#6, error reporting for the BUS concerned. 
                  7 = func#7, add-on ROM initialization for all BUSes. 
                  8 = func#8, BBS ROM initialization for all BUSes. 
                  The lower nibble 'Y' indicates the BUS on which the different routines are being executed. 'Y' can be from 0 to 5. 
                  0 = Generic DIM (Device Initialization Manager). 
                  1 = On-board System devices. 
                  2 = ISA devices. 
                  3 = EISA devices. 
                  4 = ISA PnP devices. 
                  5 = PCI devices. 
                  AC - First ASL check point. Indicates the system is running in ACPI mode. 
                  AA - System is running in APIC mode. 
                  01, 02, 03, 04, 05 - Entering sleep state S1, S2, S3, S4, or S5. 
                  10, 20, 30, 40, 50 - Waking from sleep state S1, S2, S3, S4, or S5.
                  anyway, codes 60 and 98 are almost to late post just barely before it displays stuff on the screen. code d4 is back in early post and is testing base 512k ram (ram initialisation) and is a major step back. have u tried reflowing the southbridge too? maybe it needs a reflow as well seeing how something onboard is holding up the post. if post is successful, it should display the 3738 post code when it is able to display bios boot/post messages on screen.

                    Re: P5B-plus d3-d7 post code

                    Thank you a lot.
                    I reflowed the southbridge too after witch I got an 4040 post code back. After that I replaced that one cap next to northbridge again. And now the analyzer gives 1010 to me.
                    In your tables it says "Waking up from sleep state". Im guessing its stuck in sleep so it does not turn on or something like that. I tried clearing the bios but no luck.

                    Any ideas?

                      Re: P5B-plus d3-d7 post code

                      this board looks like it has been damaged by too much ripple from a junk power supply. did u get the whole system or board only? see if u can confirm if a junk/unknown brand psu was used? if so, make sure u use a good quality branded power supply. unstable power can cause issues like that.

                      i recommend replacing all the caps around the nb/sb/dimms and cpu. the flash memory in the bios chip can also be bad and start losing its contents if the power supplied to the chip was unstable. either swap to a new bios chip or reflash the bios chip with a serial flash programmer.

                        Intergraph TDZ 2000 mainboard post code 2F/2E
                        by Sorrow1
                        Hi,

                        I try to repair an old Intergraph TDZ 2000 from 1998. It is a dual Pentum II machine based on Intel 440LX chipset. There is a non-removable bios chip named PhoenixBios B1787840. I cannot see any physical damage to the board. All caps look OK.

                        It shows no picture and POST stops with code 2F/2E regardless whether or not any graphic card is plugged in. If memory is removed, it stops on previous code 28/17 and stars beeping. I tested both CPUs in another machine and I also use RAM from another machine.

                        When I recorded video of POST card and played it in slow...

                        Panasonic ZT60 plasma tv with strange behavior and 8 blink code
                        by cloo
                        I recently got my hands on a 60" Panasonic P60ZT60 plasma tv (european model) that has some strange issues along with an 8 blink code.
                        It know this tv is getting old but it was once considered one of the best plasmas ever made, and i think it is still holds on to that even by todays standards.


                        So, long story short. When i first got the tv it had a very bright washed out picture with very raised blacks in all picture modes and i couldn't find the cause in the picture setting menus.
                        After doing a factory reset this problem was gone and the picture was back to...

                        Philips TV 43pus7505 setting display option code, help please.
                        by eurgenca
                        Hello.
                        I am dealing with a Philips TV, 43pus7505 and is stuck on boot loop.
                        So I ordered a used CPU board, and now I have wired picture.
                        I think the problem lies in display option code. According to SM, the command for setting
                        display code is 062598 + MENU + 032 (032 is written on a label on back of a TV).
                        But as soon I press the menu button TV jumps in menu. Can someone please tell me what I am doing wrong,
                        or can I manually edit option code in SAM.​
