Marantz SR7001, Focal 726V

İyi akşamlar, marantz sr 7001'i aldınız mı?

I have a Marantz sr7001 receiver with no remote control. When I pushed the power button, the stand-by light rapidly flashing on and off. In the user manual, it states that in order to reset the receiver you must simultaneously push both multi+ and speaker A/B buttons for 3 seconds or more. I, however, get no result from doing that. On your website, there is an expert that I don’t remember his/her name stating that unplug the receiver and after 60 minutes while plug in the receiver simultaneously push the power button for 5-10 seconds so that if you are lucky your receiver would be opened with the factory defaults. Similarly, I tried that one but it didn’t work. I found a video belonging to John Mendil on youtube. He was suggesting to push pure direct+7.1, canal surround+, and clear buttons simultaneously for at least 3 seconds to reset the receiver. I tried that one and the blue light from the input and volume buttons was on but nothing was showing up on the display panel. I again tried to reset given in the user manual but still, nothing was showing up on the display panel, and the stand-by light rapidly flashing on and off after the receiver works for 1 hour.

I would be grateful for any recommendation for the solution
