Hi,
when I turn on LeCroy WaveJet 324A, boot screen with LeCroy logo displays. Then display turns black and REF, AUTO, STOP/SINGLE and button "2" (channel 2) starts blinking and scope starts beeping.
Can you please help me troubleshoot this?

I don't have a LeCroy anymore but in the past I had one 324A and repaired it.
In such a case always start with the power supply inside the scope and make sure all DC rails are good and clean of any oscillations.

Thanks. And do you know what the scope signals (blinking buttons and beeping)?

No, sorry, I do not know.
When an instrument behaves strangely, a small hope is that the problem is related to a power supply issue. And in real life, I had plenty of instrument problems that were solved by just analyzing and fixing the PSU. Of course it can be something else but this is a good start.

I have a 334 WaveJet but I can't really help you with this as there is nothing in my user manual.
When I first bought the scope I looked at buying the repair/maintenance manual which was available in the US (I live in the UK) but it was going to cost me getting on £150 to £200 so I didn't get it.
It might be worth you while getting a copy, try e-bay:
TA used to sell it for $125 but it is now discontinued:

Digikey still list it but with 0 available:

Those both are for the original 300 series (the one I have) there may be a new part number for the 300A series that you have.
