Agilent 2k series LED partially light up with no display

[rizal5478]

Hello Folks, My Agilent 2k didn't boot-up properly (no display and LED partially light up then hang). From my previous understanding it seem cause by NAND IC. Anyone experience before and able to solve?

I just had a NAND experience for the first time on my DSO-X-3024A and it showed all LED correctly and the screen also turned ON correctly and bright. Just the bootup did not finish and stayed in boot loop.

So, I think in your case it is a different problem, but I am not 100% sure.

TheSteve fixed many scopes with this issue.

Ya, seem it different with my case. For your case, did you re-program the NAND IC?

Hope TheSteve will provide step to diagnose in identifing the actual failure

I told you how to proceed in a reply to the PM you sent me:

Please post your question in DSO/MSO hack thread, I will not be able to sent you any more direct messages! (forum limit for zero posters)
Use RS232 to log boot sequence to see where the problem is, see the thread how to do this.
2.41 can not boot from USB.

Yes, PAOPBZ, thanks again..  I saw picture from the thread to tap with serial-USB on the board but I don't have idea how to communicate with the PC. Seem not explain in the thread.

I also said in PM you need to connect to the internal serial port for us to help you.

It was not explained in the thread because it is considered basic knowledge, you need one of those USB to serial TTL converters and a terminal program, most of us use PuTTY.

Please do some googling and reading, we can help you but not from starting point zero.

ok noted and thanks.. i did use hyperterminal for other device before just doubt if u guys using any special GUI. Just heard abg putty and i will explore further. I had ordered USB-TTL 3V converter for this and will let you guys know the outcome later.
