Hi , I take out the LED strip from one of the LED Tubelight which stopped working.
Its Rating was: 220V AC - 22W
I take out the circuit and LED Strip , disconnected the circuit and put the 12V DC 2A power supply directly to the LED strip , but nothing works.
I have checked each LED on the strip and every LED is good to go.
They are connected as 33 LED in Series and 4 such parallel connected combinations
|1---2---3---------31---32---33|
GND ________|1---2---3---------31---32---33|________ +12V
|1---2---3---------31---32---33|
|1---2---3---------31---32---33|
So I am not getting what's the problem , isn't the 2A source enough ? but then I thought that at least all LED should glow with some minimum brightness.
So need help on this , how to debug ?
