I am having trouble with thsi toshiba the sound is muffled and very low volume the speaker's are good also when I try to shutt it off it just goes tomute the sound and when you push the power button again it won't shutt it off it will bring the sound back on.

55 inch mits. rear projection when I turn it on the power light comes on for about 3 seconds then goes off . The tv never comes on. For a few weeks I was Getting a blue/green shadow on the picture. I could kick the floor and the picture would get clear. Turned the tv off thus night, and hasn;t came on since. I get an error code of 22 when i hit the devix-menu buttons. Any help would be greatly appreciated.

My tv won't power up. No red led power light,sound, nothing. I replaced the resistor talked about on other posts about two years ago. I just replaced the flyback transformer on a recomendation from an on line tech (Waste of 20 bucks). There is a chirping noise coming from somewhere on the board, but I can't tell where. Please help! The wife and kids are driving me nuts without their tv set! Thanks, Jon
