Faulty TV - Tube or power supply?
I have a 5 year old philips TV. Recently the picture starting
'frazzled' on occasion (like the intererence you used to get when the guy down the road started using his CB!). This would happen maybe once an hour for a few seconds. A couple of days after this started, the picture went 'frazzled' for about 2 minutes, then the TV switched itself off. It then tried to switch itself on, but would switch off into standby straight away, and then proceed to get stuck in a loop. The same happens everytime you switch it on. Anyway, my first thought was that the tube had gone, but a friend (whose electronics knowledge is only enough to get him through a pub quiz) said it was the power supply. Since I live out in the sticks, and no repair man will come to me, I wanted to get any opinions before taking this into a repair shop (its a big bugger!). On the limited info I have given you, would you say it is worth the effort to try to get fixed? Any opinions welcome. Thanks, Red. |

Nothing to do with tube or psu. Sometimes these are home fixable, sometimes not. NT |

Post model & chassis number, it could be just a bad connection, or as
bad as a flyback, but they are generally a good brand T.V. Dani. FunkAndLove wrote: I have a 5 year old philips TV.

Thanks, Red. if there was 'tearing' in the picture (corrugations visible on straight lines etc) that could be part of the hoirizontal drive that has failed. The only real certainty is that this set will need to be taken to a tech for proper diagnosis, as there could be other things causing the problem. This can't be done over the internet. A Tv this new , from a major brand like Philips, is almost certainly worth repairing. -B. |

Well it's not the tube, that much I can tell you with near certainty. It could be the power supply but could be something else. |
