Okay before I get jumped on I have jumped through all the hopes I can find before even asking. In fact, I have exhausted the patience I have with RPi which is saying something because I love the concept you all have executed. I supported this so much that when the first pi I purchased gave me this problem I purchased another and another assuming I was the issue.
All 3 have the same issue and 2 came with the NOOBS preinstalled 8GB card.
Problem: No video displayed via HDMI
Here is my layout
2xRaspberry Pi B+
1xRaspberry Pi 2
Here is what I have tried installed all with no luck
NOOBS on all three
OpenElec on all three
Raspian on all three
Attached at time of boot:
1 basic keyboard
1 basic mouse
8 or 16 gb sd card
Attempted resolutions (Appropriate to the OS they are used for)
1) Hold shift at red light during boot = No fix
2) Press 1 2 3 or 4 to see if it trips the HDMI output = No fix.
3) Edited config.txt with the #hdmi_safe=1 and config_hdmi_boost=4 as well as hdmi_force_hotplug=1. I tried them individually, in combo and all together, no fix.
Note: I may yield that I goofed here. The text file was really confusing and I have no idea if I was successful in making them active or not.
The lights flash appropriately. Steady red. Reading pulses that wind down over time.
Openelec shows on network.
My TV detects a raspberry is connected by showing the name but still does not display video.
HELP FRUSTRATED BUT WANT TO SOLVE IT!
