Re: tv makes whistling sound from rear and sparks when...
By the sound of it your set might have a high voltage leak on the high voltage transformer ,the crt has a broken neck or shorted filaments,all 3 possibilities should be handle with care because of the high voltage involved,if you are familiar with tv service you can remove the back and take a look at the neck of the tube to see if it arks,remove the back cover from far away (12 feet)and then plug it in,if the tube is bad you will be able to see it but if the leak is in the transformer you might not see anything while is making the noise.If you are not too familiar be safe and call or take the set for an estimate.If the tube is bad you will need to buy a new tv.

First off I think it's time for a new mechanic. Doing an oil change and replacing the fuel filter and air filter have nothing to do with a misfire. Spark plugs and ignition coils can cause a misfire, but a good mechanic will test the coil and inspect the plugs instead of just guessing. Your mechanic is guessing and just throwing new parts at the car. A misfire can be caused by (aside from a bad coil or plug) a faulty or clogged fuel injector, spark plug wire, wiring to the injector or a vacuum leak. Since you only have a misfire in one cylinder, and you hear a whistle on acceleration, I would suspect a leak in the intake manifold. Go to a reputable repair shop and have them check the manifold for leaks. You can also check yourself by buying an automotive stethoscope, and moving it around the perimeter of the intake manifold listening for a hissing sound. Or have someone press on the gas while listening for a hiss under the hood.
Make sure switch is on, try pluging it into an external MP3 player.
No sound would be coming from the speakers if nothing is playing on the computer also look at the computer volume as well as the speaker volume control.
first things check the outlet for power.
chech and make shure your surge protector is in the on posishion.
try pluging sumthig else in wer the tv will be pluging into.
at least you know if its the outlet or the tv set.
ok now press the power button on the tv set not the remote.
dose it work.
ok problem solved.
if it did not work you can have a tech see if the internal fusse is good or bad.
i will need the model number to look futher into tech repair.
I will do this for you if you need it done.
if you see near plug it might be due to sparking in socket or plug by calling electrician it might be repaired easily.
But you have seen blue light in tv & chattering sound than it is dangerous.
do not put on tv &call skilled person.
