I have recently got an RPi, downloaded the Raspian OS, put the image on an SD card with WinImager and plugged in.
I use an USB power supply ( 5V 1A) and connected to a TV. I just wanted to see it all boot up before I got a suitable keyboard,
network connection, etc. Much to my disappointment, I saw nothing. I checked the voltage at TP1, and that appears OK ( 4.8V),
the power light is on and some chips appear to get warm.
Can anyone please suggest what to check to determine if I have a dud RPi or if I have done something incorrectly?
