Re: Power button stays red when you press it
Might be a bad tube or flyback transformer. Best thing to do is take the back off, turn down the lights, and stand behind it while someone turns it on. you may see one of the tubes arching or the flyback itself. Let me know if this helps or if you need more info.

May be its Faulty transformer is making Noise,Please check the model number of yout TV and check for Warranty ...Contact customer support for replacement or service(click here) Hope this info is useful for you..
The chirping sound is either a shorted Horizontal Output Transistor / Power FET (whichever one is used in this case) or the IHVT (Flyback Transformer) has developed a short in its windings. In ether case both components will have to be replaced. I would suggest you have a qualified TV technician come over and troubleshoot the problem and give you an estimate on the repair.
A 1995 60 inch rca good picture and sound. Then it started a cracking noise and a hissing sound, then the picture went blurry. then it was nice picture and sound, then it died. took the back off and turned out the lights. Plugged the tv in and out from the wall socket and there was a sparking noise and a small arc when i plugged it in and out a few times ,at the part that the power plug plugs into.The white part that is beside the white power plug part has thick red wire coming out of it and goes into another plug that has more red wires in it. but the big white part beside the power plug part looks burnt and has black powder on it. that part is probably the problem but maybe not, what it the name of that part and how much would it cost and is it plugged in or soldered.
a tv has two components, firstly a power supply produces high voltage to trigger a line transformer, in turn a transformer produces smaller voltages. firstly check if the ht is constantly been produced from a supply, if this is there than go to a line transformer, and check voltages at the output.
Pull off the back pressboard. At the bottom left hand corner is the power cord that attaches to the power supply board. There is a white plug that attaches directly to the power cord. With the TV power off, pull this white plug up to disconnect. Then push it back in. Then plug your TV back in and press the power button on the front of the TV. I just did this and it is working fine.
