Question about Samsung HCL4715W 47" Rear Projection Television

I smelled something burnt and a clicking noise

When the unit was on it suddenly burnt something and then is sounded like it was powering on and off. It just kept clicking and no picture. Then it stopped clicking and the picture now has three images overlapping each other in green, yellow and red. Is this a common problem and if so I hope it's not too expensive. Thanks for your help

This is a Common problem, you have shorted convergence amplifiers, some of these have a small board that is mounted behind the CRT's with a red plug/blue wire, these are incredibly easy to replace, some samsungs have the convergence circuits mounted on two tall heatsinks on a big board with the high voltage transformer (has 3 big red leads comming out of it) and requires alot more work to replace, if you are uncertian I would call the repair man, you can look to spend around $350-500 I would suspect, if you call someone might ask what convergence board replacement would cost.

2001 ford escape has horrible rubber smell and bad noise

Remove the drive belt on the alternator and see if you can spin the pulley freely. Check for bearing noise or knocks in the alternator . If it is hard to turn then replace the alternator . While the belt is off check all other units and pulleys to see if they turn freely. Now check the drive belt and smell it If it smells of burnt rubber then replace it as it is what the smell is all about.

Electrical burnt smell

If you had a short in the starter motor windings and held the key, you'd get a click and a burning smell. That would be the insulation burning off the electrical windings. There's a 40-amp max fuse in this circuit.

Washer had just started and i started to smell something, and all of a sudden a noise came from the washer and then smoke came from machine really bad, the noise sounded like air escaping

Looks like something is short circuited & due to which there is burning smell coming out of the machine. Disconnect the machine immediately & inspect the insides of the machine. Locate the burnt motor or burnt wires. You heard the noise coming out of the motor. It could be dislocated brushes due to which the motor could not rotate & in turn it burnt your motor.

TV DOES NOT COME ON AT ALL

Bad power supply. Symptoms: No display at all, no power indicator light, no sound from speakers, momentary popping or clicking noise, "burnt electronics" smell. Typically caused by failed capacitors. Can be usually be repalced and continue to have working display for a long time. Repair: Replace power supply. Super cheap when it's just a couple of bad capacitor to medium expense when repalcing whole power supply unit.

The clicking noise is the protection circuit., sounds like you have a grounded speaker wire, but you say the speakers are not connected so the amp may be toast. Is there any smell of burnt wires? This is ussuallt noticable near the circuit board if something failed!

Noise from woofer

Double check all of your cables, but it sounds like the power supply may have died. If the sound is like a mains hum, then the power supply will need to be replaced. Is it an internal or external one ? If it's internal, are there any fuses accessible ?

Sounds obvious, but double check the speakers are all correctly plugged in, by removing and re-inserting them. Check the volume controls and and other switches too. Try plugging headphones into the audio outputs to confirm their is actually a signal present, as the speakers may be fine, but the source may be faulty or its configuration changed.
