Im not shure were problem, check this resistors. Then i prepare HDD image for recovery. And i dont like this string from your console file Fri Dec 20 23:06:08 2024: DIAGNOSTIC EXECUTION starting ... Pu=2 T=-127C Maybe this couse board have somewhere bad configuration, this explains the negative temperature value and the attempt to U200. Can you take good photo your board? Two side of pcb. |

on some acq of other models you have to rewrite some eeprom, i forgetting for what code ... but it cleared some errors, you have to go in the big tds7k thread here's some others, for the given scripts i need to restart a computer to get them, the eeprom rewrite ..... not sure all related, but yes the other thread answer seems to point to something who get very hot https://www.eevblog.com/forum/testgear/tektronix-tds6000b7000b-series-nvram-dump-script/ https://www.eevblog.com/forum/testgear/tektronix-tds8000-backup-calibration-parameters/msg5755891/#msg5755891 |

After I downloaded the latest firmware from the Tektronix official website and reinstalled it, the oscilloscope would have a blue screen when I booted up TekScope. The backup dpo7054 system can be started normally with a backup and will not be blue screen. Pay attention to my console log, there is also an H10-A error that causes acquisition 361 etc. When I was measuring, I found that the vertical position of channel 2 can be adjusted, while the vertical position of other channels is not adjustable, and it will closely follow the baseline of channel 2. |
