Analog TV fault
Anyone know about televisions (analog type). It is a Panasonic TX21MIT/BK.
I only use it for playing DVD's and VCR's. It worked fine until today. Today when I switch on, the power light comes on, but there absolutely no sounds of any kind (no high tension activity, I think), I see nothing on the screen whatsoever. Is this something that's easy to fix? (I seem to recall having a TV problem once before and it turned out to be a bad connection on the back of the tube.. Thanks Al |

Thanks Al Sounds like a PSU problem, but could also be a LOP problem, since the 2 are fairly intertwined. First things to look at are to see what power lines are up, what arent, and check any fuses and the LOPTr. I don't know what sort of skillset you have, so not much point me saying more. If you don't even know what a line output transistor is, bin it and get another. NT |

Does anything happen if you leave it on for a while? Can you find the schematic online? (not always an easy task, particularly when several set designations share a common - but not always listed on the case - model number) It sounds like the PSU is doing *something* useful if there's a power light as these are normally LEDs in any TV that's remotely recent. You say "no sounds" though - does that include normal audio output? I'm surprised that you're not getting something from whatever channel it was tuned to, even if there's no HT and picture. (I seem to recall having a TV problem once before and it turned out to be a bad connection on the back of the tube.. Yes, never rule out the simple - although for that kind of fault I'd expect you to still have normal audio. cheers Jules |

Maybe you've switched it off with the remote. Try hitting a channel button after switching the set on. For some slightly annoying reason my Sony CRT set remembers the remote control activated 'sleep' state through a power switch toggle. -- Adrian C |

For some slightly annoying reason my Sony CRT set remembers the remote control activated 'sleep' state through a power switch toggle. I never had a remote for this TV. I tried pressing channel up and channel down switch but nothing changed. There is no sound whatsoever. Thanks to all respondees. I'm not an electronic engineer. The most I've done is a bit of soldering, e.g., building small ghizmos from circuits in Practical Wireless. So I guess it's time to go telly-hunting again... Thanks anyway.. Al |

The DVD player is about ten years old and has an S-video output, plus a scart output and a number of phono outputs Only if the monitor has a 'TV' input (eg SCART, S-video). If it doesn't, look up the specs of the monitor. It probably can't sync to the PAL video from the DVD (15.625KHz line rate) but worth a look - if it does a passive SCART adaptor will do. Theo |

Either SCART, or possibly a yellow phono socket for a composite input. Otherwise, use a cheap laptop computer as a DVD player.

It should, but double check with the seller on the 0844 number near the bottom of the page. It seems to accept either composite video, for which you'll need a phono to BNC converter, available for pennies from Maplin, or S-Video, both of which you say you have on your player. -- Tciao for Now!

Most people seemed to manage until a few years ago, and quite a large fraction of flat panel TVs still occupy the traditional corner position. |

I've seen them on ebay for £26. I guess that means it's 'no good', yes? I've got a couple here which convert composite, S-Video and RGB TV signals to VGA. Wanted a computer monitor beside the workbench which would also accept TV signals. For test purposes. Neither works what I'd call well - things like not changing from 4:3 to 16:9. Vertical lines regardless of the VGA resolution chosen. Of course it's possible there are ones around now that are better. A better solution for me was a TV with a VGA input, and the usual SCART and S-Video. That works adequately as a computer monitor as well as a TV or TV standard monitor. I'll do you a deal on one of them if you wish. ;-) -- *Why is it that rain drops but snow falls? Dave Plowman London SW To e-mail, change noise into sound. |
