content: Hello, I have a Tektronix MSO5204 oscilloscope, but the error when loading the screen and the jam only sounds the first relay and the second time a dialog appears like the picture below.I've tried updating the firmware. I've even tried returning to the initial Windows settings that were backed up before the error. the results are still the same. I've turned it off, unplugged it and waited a few minutes, the results are still the same.But sometimes I force it to turn off from the power button. Then I restart it. Sometimes the oscilloscope program can function. And if I turn it off and then turn it on again after 30 minutes, the oscilloscope is stuck again.What's broken? What's the possibility of hardware? However, I checked the device manager and everything looks normal.

content: There is probably an internal serial port for debugging.perhaps the software is crash because the acquisition micros is failed to boot and cannot communicate.

content: Thank you for your reply sir, may you always be healthy.Then how to analyze the debugging port?I have tried to restore windows to the initial version I bought, because I had previously Ghosting. but the result is still sometimes stuck.

content: okay sir, I uploaded the zip file. Actually, since the first time I bought this oscilloscope, I have backed up the image with ghost. and when there was a problem, I restored it again but the result was still the same.

content: there are a few errors that are of concern.QuoteBet on PSU.The last time it was used would have been December 2, 2022.(line 100974)I assume you then purchased mso, and replaced the CMOS battery.since that time getting I2C errors, and I would guess from the errors that they are caused by thefront panel board.

content: does that mean there is a high probability of error damage to the PSU and front panel, sir?I bought it in December 2022. But on December 2nd I replaced the hard disk with an SSD. And I have never replaced the CMOS battery. But I have removed and reinstalled the CMOS battery because the computer would not run. It initially happened because the computer suddenly turned off due to a power outage.Since then I have installed a UPS and over time strange things have appeared. Like the LCD screen suddenly goes blank. I tried cleaning the sockets and it returned to normal. But now a problem like this appears. Sometimes the program can start, sometimes it gets stuck.Or is it the PSU that is at fault because I am using a UPS that is not a sinewave?

content: not sine wave (like square wave or modified sine wave) can cause a variety of problems.especially with switching power supplies. It is not so much of a problem with transformers.perhaps that is why the power supply is damaged. I think it needs to be recapped(primary side?).

content: after I noticed and I remembered again, when the red fault led light is off, it is certain that the program can run. and this is the only one that lights up the green led. but if the red fault led here lights up together with the green led, usually the program can run and most of them are stuck.

content: I just said, and this red led lights up when my 220 plug socket is removed. I wait for 5 minutes. and restart it, the red led lights up and blinks at the start. Then after the program runs, the red fault led keeps flashing and the program gets stuck.
