My TV is 3 years old. Sharp 32'' Flat Screen. For few months now I hear static sound as a background. It usually gets loader while the picture has more 'white' areas in it, in other words when the scene in the movie/show is brighter.
Even if I mute the TV the sound will stay and, again, get stronger when you have a 'whiter' scene.
I hope I can fix it...it realy bothers...we already thoughts to trash it...
Appreciate your help.

Re: Static 'white' sound
Try to remove the cover of your unit and clean the tube with a dry cloth. try to look for the anode cap. the one tht is connected to your tube if there are holes in it. This causes the problem.

How old is this TV?
Sounds like it has high voltage failure.
(If you hold your hand on the screen when you try and turn it on, do you feel the static? )
Unless the set is over 10 years old, I would overhaul the high voltage circuit. Should cost under $200 at a shop.
This problem sounds like a short inside the picture tube itself unless a driver transistor failed that drives the red gun in the CRT. You may have to take it to an authorized repair facility if the picture tube is still in warranty.
What type of Universal Remote Control can I purchase for a ZENITH Concierge, Model H2735DT, TV?
Please supply brands and model or serial numbers of remote types.
It sounds like the circuit board is arching over somewhere. It could be as simply as cleaning and digging out the carbon mark to stop the arching. This is most likely the screen or focus voltage causing this, if there are no parts that have broken down. This will damage the printed circuit board and make things worse the more you let this cook. This could be dangerous for you to mess with because of the high voltage present, so my best advise would be to get this into the repair shop as soon as possible before this board burns up. It should not cost all that much if the CRT board can be repaired. Good Luck
What your describing sounds like two differant problems OR the power supply is causing these two problems .. One would of course be the tuner and the other would be the vertical circuit .. Your going to need to seek out a profesional if you havent a clue about solid state electronicsand A tv is not a place to experiment! Good Luck
