Bad EAROM perhaps.That means you may have lost your calibration constants that the microprocessor loads into registers throughout the scope to set gains,timing speeds,etc.

04 fail 10 means bad checksum, bit 4 set. Or in other words: He has to run through the cal process.The OP can download the service manual for free from

This manual includes all the schematics and calibration process steps. Good luck!

Thank's for answers. I will try to calibrate scope . If it will not set then EAROM is bad. Where is possible it to buy EAROM?

If he recals,and then gets another fail message,then the EAROM is bad;it's not retaining the data. We used to replace a lot of EAROMs at TEK while I was there.
