Hi! I got DPO7104 in very bad condition, looks like this device play footboall, as a result most bga get off from pcb.. with pcb traces off.. But! I repair traces on PCB and find donor PCB for replace broken BGA IC, in this time device work fine! Like DPO7104 with many options. And it would seem that everything is fine. --- Code: ---================================================================ SYSTEM INFORMATION: Stingray Model: DPO7104 Serial number: B010496 Scope.exe Version: 5.3.5 Build 22; RELEASE Diagnostics: Powerup mode: USER Powerups Count: 88 Timed Demo Info: Timed Demo, 0 days left.

Popup message like "NVRAM file cant read for this device, dude go to tektronix service" I wont write all consuption info and litlte photo about this DPO7k scope and how convince him that he is DPO7354! But.... First i wont make sure everything is okay. For this i need: Can someone who have access to this model DPO7354 (and 7254) copy here folders C:\TekScope\calibration and C:\Program Files\Tektronix\TekScope\SYSTEM I have no idea were NVRAM "file" in this scope.. I started this repair in June, this most hard reapir i doo, because of many BGA pad repair, tons pad BGA repair. |

Hi guys, I think im just fu my tds7254b. After an hour installing the TDS software but screen still stuck as this img, im pretty sure that NVRAM's battery is dead. So i tried to connect it to my computer using FT4232 serial. Every thing seem good but when i power on the scope, the teraterm display an inspected symbol like that. My serial config: 9600 8 N 1 I tried different baudrates but no progress. I don't know what I did wrong. Now this scope is stuck at the application launch screen. Front panel is not working, bit indicator on the bottom of mainboard is stuck at "L" state. I don't know what to do next About the VM6000, yesterday I tried to flash the file squadchanel gave me, but it kept getting BOD, so restoring it with the archive file is not feasible,I'm looking for some thread or tutorial that can turn my VM6K into an oscilloscope. Anyway, thanks for your kind support. Sincerely, Feng |

1st where are you connected ? you have a 10 pins idc port on the power pc board not far from the pc and scope interface j790 this thread should help https://www.eevblog.com/forum/testgear/tek-csa7404-repair-project/ and don't multiple thread, you had already an ongoing one .... |
