I have a pi2 Model B v1.1 which has been working fine for the last few months. I have 2 micro SD cards, one with raspian on and the other openElec with XBMC. Yesterday they both worked, today, neither does. When I connect power, the TV via the HDMI doesn't display at all, but there is life via the flashing lights.
Using the OpenElec SD card I get:
solid red - green flickering red pulses -green flickering solid red - light green flickering occasional red blip.
Using the Raspian SD card I get:
solid red - light green flickering occasional green blip.
I thought that it may be power supply related after following R-Pi troubleshooting guide, as the red light was blinking, so...
- I checked the power supply voltage from the Pi2 (underside PP1 + input housing)and it read 4.92v (sounds fine right?)
- I used a totally different power supply and different cable (no difference)
- I thought I might have corrupted the SD cards, so have just re-imaged the Raspian with the latest version 3.18. No Joy.
- I edited the config.txt file on the new raspian image and added all configurations in "No HDMI output at all". But no luck
I think I have bricked my Pi2. Help! Does anyone have any other insight?
