|
|
i have a toshiba 34hfx85 cinema television that i just got. the guy said it just quit. i can turn it on and then it just goes dead instantly. the red power light comes on and then goes right out. you can hear the tube power up and then shut down. i took the back off and looked at the fuse and it is good. i looked for bad solder joints but didn't see any.
any help would be appreciated. |

if you just got it, it should have a warranty. |

from "the guy."
I've never heard a "tube" power up. Maybe degaussing you're hearing? |

it makes a noise like a normal tv. you get static on the front for a brief second. then clicks and it is off. when i try and turn it back on the red light comes on and then back off with a relay type noise. it doesn't make static after the initial turn on. |

Has High voltage for a moment and then nothing.
Can you try running set at a lower AC voltage (Variac)? |

I'm just trying to rule in or out the possibility of a bad regulator. 80VAC. |
