If the pcb is produced for learning at schools it's ok, but for homes and offices it's unethical.Thanks

Thanks for your comments, infact i don't know those colour leds use different operating voltages and i
have replaced red with yellow led in the past.Now i have gain invaluable knowledge from you, i appreciate it and thanks for sharing.

Imoudu,
Good repair,
Have you brought led PCB From the market? i know some manufacturer who are making PCB for school / College students for learning & troubleshooting . intentionally they print this type of marking so that students learn to trace the circuit & fault finding.In fact for misguiding some manufacturers are putting dummy components by which does not have any Link / connection on the PCB .

Good job. It is really amazing how leds have evolved in performance and quality of light and the so many colors. Even the new UV leds and Flash light leds are astounishing. Many new devices wouldn't even be possible today without the modern existing high bright super low current leds. Different coloured leds have different operating voltages with matching serie resistor to limit the max current. With a forward voltage of only 1.5V for IR leds it is the lowest, Red/Orange is about 2V, followed by Green with about 2.2V upto Blue/White being about 3.2V, Purple being about 3 to 3.6V ending with energetic UV leds being as high as 5 to 6V. At best if possible we replace the same led colors as originally were used.

Yes, you are very correct! I have seen such deliberate misguidance in many sets. Unless we are aware and careful about such deceits, we will end up burning our fingers! Many thanks for sharing!

Thank You for this post. The knowledge that manufacturers actively mislead to make a buck is sinful. keep up the great work and keep posting!
