DSO4254C Boot Problem

Millbrook

Hi Jing,
I have a Hantek DSO4254C that has failed to boot, it is stuck on the QR code screen. I cannot access the Utility mode or any other.
The VO, Run/Stop, Single, Auto Scale, 1, Math, @, 3, and 4 LED's are on.
The Serial no. is CN2147002007171
The unit has not been used for 2 or 3 months.
Please can you advise what I can do to bring it back to life
Thanks
David

I have just discovered this fix on Youtube.

I tried it and it worked first time.
I am now a happy camper.

Hope it works for other folk that have this problem.

Kind Regards
David
