i have followed the http://elinux.org/R-Pi_Troubleshooting to troubleshootmy raspbbery issues.
until a week ago it used to work fine. after a week to be switched off, i am trying to boot it but all it does is a red light on the pwr led. i ahve tried different power supplies (that used to work for raspberry and they do work now on mobile phones). with the use of a multimeter i took a meter shot and it gives me the correct output. i have tried different sd cards with different OS, no luck.
all cards boot my PC through media adaptor and it works (just for check).
what am i missing?
