Need Help With TV
I have a Philips TV model 32MF505W/17 that has no sound. Something popped and
smoked and when the sound stopped. The picture is still fine. I've taken off the back and took off the center metal cover. Everything looks fine there. There is another metal cover that I cannot take off without being a little inventive. Under that cover I suspect will be the amplifier board? There should be something visibly burned there but I can't see it with the cover in place. If that circuit board is fried, is it possible for me to buy a new one and install it myself? |

My computer speakers have a different connection. I don't have a stereo on hand with an aux input. Thanks for the suggestions. I'll see what I can dig up to test this out. |

Well, certainly there are other things that I would rather mess about inside, but right now I'm concerned with the TV. |

Trying to fix something is better than slingin insults, which isn't all that productive, yeah? |

With HC/HV (high current/high voltage), you rarely if ever get a second chance. Not to mentions, that just acquiring the tools to do the job correctly can easily cost more than a repair. At least have a friend that knows electronics help you. If you make the currently wise decision to take it to a shop, they may let you hang around and watch them troubleshoot it and fix it. I understand that taking things into a shop to have them fixed, may not be economically viable for everyone, but a television is not worth dieing for. |

Mark, I have to say that you definitly put it like it is. I can't tell you how many people have told me over the years something like, "my TV won't come on and the little power button in the front needs to be replaced". Or they want to buy a resistor to replace the one that has completely illegibly incinerated. I will talk them out of the repair, however I have friends in the trade that will sell them the fuse and resistor because they know as sure as there will be another sunset that as soon as the next smoke test is over, he'll never hear from the fool again. ..Lenny. |
