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.

Power light not on, no sceen on , whistling sound coming from tv

The whistling is caused by the power source that is overstressed by a short - a big part inside it has failed. The tv must be opened and the parts tested by a pro. Call one, there's nothing else you can do.

Ur tv the high voltage it dead,the FBT,the flyback transformer.The big black block of plastic with a red wire with a black cap that hook up to the CRT(tv tube) is dead.The FBT,flyback transformer needed it to be replaced to solved this problems.Call the shops,take estimates for the best deal to do the repair.This is one of the main part of the tv to put HV in CRT(tube tv).It pretty hard to find this FBT these day,because of the discontinue of making of Amalog tvs.

Tv wont turn on

it sounds to me a transformer in your set has gone hard to say witch. im guessing it is a CRT set the best thing i could suggest would be to take it to your local tv repair shop they should be able to sort this for you and it shouldn't be to expensive.

Television won't power up

It sounds like the high voltage circuit got damp and arced. This arc caused the horizontal output transistor to short.
You might try replacing the output transistor if you're experienced in this type of repair. If not then you need to take it to a repair shop.
The "whistle " you're hearing is the power supply indicating that it has a short on its load. When the power supply has an over load (short) its frequency drops down when your ear can hear it oscillating. This type of power supply is a switching power supply normally operating a several thousand hz(cycles) which is out of range of human hearing.

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.

TV screen wont turn on but just a loud noise coming from the tv

I think maybe the G-board needs to be replaced. A TV shop will have to repair it. They normally start around $200.00
