The TV I'm interested in buying (as a 2nd TV...not the main one) is an
inexpensive Sylvania 20" flat screen CRT TV. I happened to notice that what appears to be the exact same TV is available at Circuit City under their ESA brand name for $20 less (due to rebate). It likely is the same exact TV as the Sylvania, but is labeled differently for Circuit City. I'm just wondering if I ever needed to get this repaired after the warranty expired, would the ESA brand name be a problem in terms of finding someone willing to fix it? On the other hand, the TV only costs $120 to $140, so maybe it's not even worth worrying about whether or not it could be repaired, but I believe at least one place in my area offers free estimates on repairs. Is the ESA brandname a problem if it should ever need repair? Thanks, J. |

The ESA Line is built and back by Funai Corporation, they are supplying both
Service Literature and Parts for these sets. BTW Funai also makes Sylvania. "jeff" wrote in message news:f0bud.2498$pZ5.840@trndny06...

Service Literature and Parts for these sets. BTW Funai also makes Sylvania. And the big problem is Funai has no support for these names. Buy an ESA, you have to go through Circuit City for parts or manuals, Sylvania you have to go through Sears for parts or manuals. Call Funai and ask to get any parts for these brands and they will just refer you to Sears or Circuit City. Let me guarantee you it is *no fun* to attempt to order parts through these companies.

P.S.
Some really cheap DVD players and combos don't have parts availability, for these I've gotten referrals from some of these companies, which means "buy a new one". The parts I've gotten from them were for the bigger 27" tv/vcr/dvd combos. Mark Z. "RonKZ650" wrote in message ...

I just emailed them last week for Syvania parts, got the very polite reply "Sears model, go to Sears", damn idiots there are lucky to have the sense to answer a phone. let alone supply parts. "Wemote contwol? There as no list for that pawt" ARRGG. Ron Ron |

Sears happened to have a sale on the Sylvania 20" flat screens for $99 so I
bought it today. I guess, for that price, if should ever break out of warranty I could always simply get another inexpensive TV instead of repairing it. Maybe I'm being very picky, but even though the TV is supposed to be a flat screen, to me, it seems like the actual screen of the CRT tube itself, inside the TV, may be very slightly curved, (not truly flat) and they compensated for it by adjusting the picture geometry. Granted it could just my imagination or perhaps I'm being very nit-picky. Can't complain at all for $99 though. By the way, is there any way I can adjust the picture geometry, etc. myself? In other words, is there a special key combination when powering up the unit that would allow me access to special extra setup commands, etc. Thanks, J. |

It certainly is flatter than a standard CRT, but it's just that it appears to be curved slightly on the inside and have subtle imperfections in the shape. I guess for $99 (regularly $139) I should not be complaining. By the way, how long can I reasonably expect this TV to last, that is, how many thousand hours is the expected lifespan of an inexpensive flat-screen CRT TV manufactured by Funai? Thanks, J. |

Those are about the bottom of the barrel, I would say 2-3 years of moderate to heavy use. You might get lucky and have it last a decade but I certainly wouldn't expect it. Probably 20% chance it'll fail within the first year. |

Question: I have an old Emerson (made in 1988, and made in Taiwan). The model number is ECR1350. It's a 13 inch TV that has been used a lot in the past and is used only lightly now. It is 16 years old. Was this one really made by Funai? J. |

Sometimes you get lucky. TV's don't fall apart as quickly as cheap VCR's at least. |

The beam sweeps across the screen at a constant rate, the distance makes no difference, we're talking about something with effectively zero mass travelling at very high speed, a few cm will have no effect. |

Emerson built their own sets back then. Some were pretty decent really. Only recently has Funai taken over making most the low end sets. |

Jeff,
According to "Choice", who collect figures on failure rates of various appliances, there is usually hardly any difference in the failure rates for cheaper versus dearer items. Typically 98% of dearer items may be trouble free in the first year versus 96-7% for cheaper items. Since the price differential may be huge, you would often be better buying two of the cheap ones! ![]() I've bought many cheaper items over a lot of years, since I mostly buy pretty much on price. Nearly all these things have worked fine for many, many years. As for the alleged 20% failure rate in the first year of use for cheap stuff posited by another poster? Fantasy. People have to give one year warranties these days, and they just won't stock things that are big trouble for them re returns.

Melbourne, Australia - couple of months ago I bought a 21" "Sonwa" - Chinese brand X - dead flat screen, stereo sound, s-video input. Perfect picture. Bought it for $199, but now being sold for $150. That's $150 Australian. That's probably less than $100 US. Good for consumers, but bad for workers in the electronic and computer industries. I would say it is also bad for our economies... Henry. |

Ross That was based on my own experience, we've purchased a large number (several hundred) TV's and VCR's over the last few years where I work, and while they're quite heavily used, quite a few of them, likely closer to 10% did fail early on. They had warrantees but the problem is they make you pay return shipping so in the end people usually just junk it and buy a new one rather than search for a suitable shipping container, pay to send it back, and then wait for the replacement. |

As best I can tell by looking closely from the outside, the CRT appears to be *almost* flat but I do agree it seems to have a *slight* curve. In other words, as best I can tell, the surface of the CRT does not seem to be nearly as curved as a "classic" standard CRT. J. |

It really depends on the tube, some are quite flat, some are just as curved as any other modern CRT. They're not as bad as the old 80's tubes, but more like the "reduced curvature" ones that came out in the mid-late 80's, which for some reason were advertised as "flat, square" tubes regardless of the fact that they were obviously not flat. |
