PULSe 4k wake-up issue

Hi all!

I have receiver mentioned in title with OpenATV 7.4 image. I have this receiver since Tuesday this week. My problem is that if my receiver is longer time in stand by mode, then after I turn on I need to wait around one minute until picture apperars even if the touch button on the front panel is blue. If during this time I turn off and on again, the picture appears immediatelly, so I dont think that it is a hardware issue. For shorter time in stand by this issue not happen ie. picture appears immeditally after turning on. The receiver is in standby and not deep standby as I see the clock on front display. Is there any idea what can cause this issue and can I solve somehow?

It not gives the signal to the tv through HDMI during this around one minute of time, as my tv shows no signal on hdmi port, like it is switched off, not black picture. Maybe I did not write it w beforeell. But the touch button changes from red to blue on the receiver. And after a minute there is a tv programme appears on the tv without any further control

Today morning after more than eight hours powered off ie. in standby I turned on and picture comes immediatelly. Weird.

I rebooted yesterday, but I did it earlier, so I don't know is it changed anything. What I also tied is that ti check is it a clock on display in deep standby, I was put in deep stans by and woke it up from there. Also don't know it can be change anything. Soit's weird anyway. If it happens again I will try another HDMI port, honestly I used this port for VU+ Zero 4K for long time, also except this issue my PULSe also works fine on this port. Maybe I'll try OpenATV 7.5 if issue happens again

Interesting. I tried another HDMI port on my tv but the situatuion is same. If I power on the TV first, then there is a signal imediatelly on the TV and program starts. But when I power on the box first, than after a minute or two came the signal on, until then my tv shows no signal on that HDMI port, however on webif when I capture a screenshot I see the programme even there is no HDMI signal on the tv for a while, so the box started to work

Can you give me a screenshot on this setting?
