A simple fix- LED bulb

HOW IT WORKS:

It uses a simple EMI filter followed by a 'bridge and a filter' which supplies
dc current to a series of LEDs.

TROUBLESHOOTING TIPS:

1) After you open the casing, see for any burnt component. If you find any, replace them.
2) Check for any faulty LED using a multimeter.
3) Check the copper track.

CASE STUDY:

- Here I found one, which had a faulty LED. There were traces of liquid flow around the same which must have been responsible for the dead set. (A OPEN CIRCUIT!)
- Now due to unavailability of any spare LED, bypassed the same using a 1N4001 diode.

And, bingo!!

FIX A LEAKY SINK FAUCET

Company: ROYAL

Item: Half turn designer sink faucet.

PROBLEM: Leaks water in fully closed position. Applying pressure laterally on the knob increases or decreases the quantity of leakage.

WORK TO BE DONE:

- Check whether the leakage is from the flow end or at the joints.

- If at the joints, a worn out washer could be the cause.

- If at the flow end, it is the channel, where the problem could be because of a worn out washer or something else.

- Here in the case, it was the latter. In such a case, open the faucet from the knob end.

- Look for a small opening usually closed by a plastic lid. Remove the cover.

- Using an Allen Key of the proper size, unscrew the knob from the fixture.

- Now using a spanner or a plier, unscrew the cartridge form the fixture.

- The cartridge has a rotating knob, a set of ceramic discs that performs the opening and closing function for the water to flow or block, and a few washers.

- Dismantle the cartridge and wash properly all its elements to remove the sediments of mud from every corner. Refix it back to shape later. If all the washers and the discs are fine, then this much should do.

-Screw the cartridge back to the body and also the knob.

This much of patience worked for me. TRY IT YOURSELF.
