I just bought a 27 inch Sharp TV about 3 year old. It makes a continuous quiet hissing sound from the internal components when the set is turned off. Is this normal? Our other TVs do not do this. Everything else seems fine. Picture and sound are both great. Thanks.

I believe you have lost the green channel leaving only the red and blue. It could be an internal connection like a solder joint or connector, or it could be component failure from the CRT to an adjustment pot. Being the set is ten years old it wouldn't be worth spending a lot of money on it. You can buy a 27 inch TV now for almost what a repair would cost. If the picture was very good before this probem you may try to get it fixed cheap. Otherwise it probably wouldn't be worth it.
My 27 inch TV's (A Sony and a Sharp) are pretty old and I would fix them myself if the picture tube was very good.
This may be a very good time to buy considering the discounts being offered. ;-)).
I sorry to say I think you have a component failing that is related to heat. 15 years is a long time and if the TV was used in hpot conditions over the years it may well be the proble, or it's just old.
I have a vcr and dvr combination emerson tv a 27 inch and sometimes while playing it will flicker and these horzion lines come in while a program is runing, and then the sound goes way down then comes back up to normal.
You got the right idea,use the ext.imput on you tv and use the vcr to change the channels,you can check the solder conections in the tuner ,ussually the ground gets loose after a while but if you are not too familiar with tv service and dont want put any money in this set use your vcr.If the quality of the picture is still good then is worth keeping it.Let Us know if you need more information.
