Posted: 4/13/2008 6:33:15 PM | | lol, i think your tv is broken internally. it'll just keep doing that until it doesn't turn on again... you can get it fixed, but if its a projection screen, its probably not worth the money. just get a no interest for ___ months credit card from bestbuy and get an lcd tv. that's my advice anyways. | |

I'm guessing this is a CRT projection. In that case, several models made by magnavox and RCA are prone to failure on the blue CRT tube, which produces a problem very similar to yours (Except the maganvox model fails entirely, and both other tubes blow with it)
You'll need to call someone in to service it, most stores like Best Buy won't service it in-store if it's over 25" However, given the noise and average repair costs, you might consider replacement. CRT projections aren't particularly sharp TVs to begin with, and DLPs are coming down quite a bit.
If it's a DLP or LCD projection, some bulb failures can do this, check for scorch marks on the bulb. | |

You can call around to tv repair shops & get price quotes. One of the big expenses will come from the repairman/woman coming to your house. | |

Posted: 5/29/2008 4:28:28 AM | Hi,
The hissssssss you hear is likely an electrolytic capacitor that's dried up and gone high resistance. What happens then, is whatever they're bypassing/smoothing/storing gets subjected to excess noise/ripple because it cant' do its job any longer. As a result they can no longer do their job any longer either, and you get a chain reaction of failing components and circuits.
Protection usually kicks in and shuts it down before very long, but every time you turn it on again, you increase the odds of furthering the chain reaction. Looks like your warranty saved you. Repairs like this aren't cheap. | |
