Does the computer have a programmer's switch that could have gotten bumped during shipping? If so, try removing it. I don't know if it applies to the SE/30, but Dead Mac Scrolls associates this kind of problem with a jammed programmer's switch in some earlier macs.
The other cause that Dead Mac Scrolls suggests is a faulty chip on the analog board but that might only apply to earlier models also.

I guess it does not chime when you turn it on?
That screen is showing up when the ROM can't be accessed either due to bad contact on the SIMM or broken traces.
I suppose this is the machine that you got from amibay and it got bumped hard in shipping I would check the ROM SIMM once more.
The SIMM sockets with plastic tabs are notoriously bad and prone to failure. Try to really push the ROM in place and keep it tight with a rubber band and see if that changes anything.
In the pictures above the clips barely engaged (if at all - hard to tell) which would result in bad contact.

.... if you bought it working, don't wash it - easy way out for the seller to refuse any refund, in my opinion. Once you start doing extensive troubleshooting (and washing), the seller could just come back to you and say you damaged it. Clean the RAM, ROM contacts with electronic contact cleaning spray, just run with four known working sticks of RAM.

The seller does not wants to cooperate unfortunately.He blames that I open the machine first...I did it his favour and send him money with PayPal gift-unprotected.His answer is the following:
"You didn't do me a favour paying by Gift, I insisted on it because I knew if it got damaged you would behave like this.My reputation on this site spans 10 yrs or longer without incident or people claiming I have sent them items not as described.I can tell you now, recapping that machine will not make it boot. The board was damaged in transit and you accepted that responsibility.Can you honestly explain to me how I took pictures of a working system fault free on my bench before I sent it to you !!!! I have the time stamps of the date the photos were taken to
ne further reason I am not happy about is that you have stripped the machine right down and handled the board before reporting it as damaged, if you wanted me to share responsibility maybe you should have advised me first before stripping the machine down and handling the board.How do I know if the system was booting before you took the board out !!!! See it works both ways !!"

I still have the same horizontal bars in the SE/30 which had capacitor nasty leakage despite having it recapped and replacement of the few chips plus fixing of broken traces.
IT happens when I open the case and there is motion underneath the mobo, might be some bent pins which cause this issue. All I need is to to take off and gently put on this aluminum port cover again. When it sits still in one place it's perfectly fine.
