[QUOTE="marcher, post: 522577, member: 12538"] Not an easy task! You may be able to gather some clues by powering up slowly using a variable DC power supply. A dead short would not power up at all so this can be discounted as most of the LEDs flash. If you can raise the voltage to a point where most of the LEDs glow dimly it should be possible to find the failed LED or at least the faulty branch. I suggest a small 0-15V 3A PSU with current and voltage meters should be suitable. I can loan you a lab supply if you are located near Twickenham. [/QUOTE]
