It's been a few months since I last posted about this 34461A meter with the white screen when turned on. Worked I did on it since was get a used front panel pcb from someone on Ebay that was suppose to be working but it turned out to have a shorted Spear processor pulling down the 3.3v supply to it. That person then sent me another one. Same thing shorted processor. I found a supply that have correct spear processors and purchased them. So, now in total I have 3 bad front panel boards. I decided to try replacing the spear chips. In the process I damaged 2 of the boards by tearing off pads under the spear chips while cleaning the pads off with solder wick. The third board I was lucky and sucessfully was able to put down a new spear IC. Upon powering up the meter I now get Agilent in black lettering and a black bar representing that it was booting up. After that bar reaches the end a small part of the LCD screen (upper maybe 1/5 of it) displays part of I think Windows CE loading but stops there and then nothing else after that. So, I made some progress in getting it working. I still need to attach a serial connect to the front panel to see what else is going on. I will be using a serial to usb adapter for the connection that I use to talk to PIC micocontrollers. This uses 5 vdc I/O connections. This port on the front panel is it 5 vdc tolerant. I suspect it might 3.3v. What did you use (hardware) to communicate with the front panel? I know that I am not using the original front panel now and serial numbers will not match. Should I even bother proceeding because of this? |

I got serial communications going and this is what I came up with. Maybe someone can give an opinion. I was thinking maybe loading the 2nd image and see what happens but don't know how to get to that menu while booting the unit up. --- Code: --- U-Boot 2010.03 (Oct 09 2012 - 12:48:30)Agilent P510 CPU: SPEAr320 DRAM: 128 MiB Unknown id: 0xffffff.

I'm watching with interest as I have a 34461A with same symptoms as you, white screen, no uart output. Like yours, cold Spear but it probably needs replaced. Regarding swapping the front panels - there is an soic NXP LPC 8051 type mcu on the board and IIUC it has eeprom containing the meter serial. When a new panel is connected it receives the meter serial from the motherboard and is thereafter locked to that unit (thanks Keysight, very nice of you). I need to try swapping that mcu between panels to allow panel swaps. I also see that mcu has had fw protection bypassed by glitching the reset - would be nice to get a copy of the fw and eeprom. Looks like your pboot is OK but perhaps needs an nk.bin to boot to. Somewhat similar to the OP of this thread, after they had fixed their pboot. Maybe reading this thread from the start will provide some hints? |

Was thinking about swapping the NXP LPC 8051 from my original front panel pcb wih the front pcb I have the new sprear processor tonight. Reason is because I read in previous comments that NXP LPC 8051 may hold the meter sn. That's an easy thing to do just to make sure that's not causing issues. Easier than doing that Spear BGA. I needed to make sure the spear processor aligned up perfectly on the pcb and decided to create a kind of drop in template that I placed on the front panel. Drop the spear into it and it is exactly aligned before applying hot air to the spear and the board underside. If the switching of the NXP LPC 8051 does not make any difference in booting then I will try loading the second image. I read the entire thread and it is a lot to digest and make sense of. I'm going to try doing the easier things first. |

Swapped the NXP LPC 8051 with my original one and it didn't make any difference in the bootup process. So, then getting to the UBoot menu options I selected to load "image 2". After that I still got the same white srceen with the black Agilent text and the loading bar at the bottom. After loading is completed I wound up with just a black screen and nothing more. No, USB communications either. Haven't tried ethernet because I don't have a crossover cable. I suppose I could use a switch which I have to connect up to my laptop. When I do load image 1 I get the white screen with black Agilent with loading bar and after it done I get a partial blue background maybe upper 1/5 of the display and then the unit freezes up and nothing more. So, anyways here is what was displayed after booting image 2 it's only slightly different than Image 1. I'm stuck right now on what the problem is.
