First time ever posting on any forum whatsoever!
My son and I have built an arcade machine and a jukeboke using Raspberry pi 4B+. We have found that when we power the 240v powerboard that has the raspberry pi power cord and the tv monitor power cord attached, the tv will not pick up the Pi signal and always displays no signal on the monitor.
We have to open the unit, power the TV first, wait until it fires up and at a certain time power the Pi. We have tried looking for a delay module but nothing seems to be clear on whether it is what we are after. We would want power delay to the raspberry Pi so tv can fire up first (we think?) Or is there a code get around to delay hdmi signal from pi to tv? Or, Is there a purpose made module for this? Not overly savvy with solder yourself modules but would be willing if only option. But a plug and play would be ideal.
Thank you in advance.
