Projection TV Woes
I have a Hitachi Projection TV (55EX7K) that's about 11 years old. Recently,
black bars have been appearing at the top and bottom of the screen. When you walk across the floor in front of the TV, the bars flicker and change size and sometimes go away. After the TV "warms-up" for a while, the screen will return to normal size without any further problems. This morning, my wife said she heard a small "pop" and the picture displayed briefly before going out and then flickering back on. I had her unplug the whole thing completely, just to be safe. Before I call a repair-man, is there anything I should check out? I realize that the TV is getting on in years but if the repair is under $300, I'd like to keep it. Thanks for the help, Sean -- \___/ Sean Keplinger |o,o| skeplin at one dot net \/ ) http://spookyworld.dnsalias.com ----mm----------------------------------- |

Suggestion, unless you are deeply in love with this set put your monies on
newer technologies. Much has changed in the decade + since you have purchased that particular set. Having it repaired can easily exceed the $300 limit that you have already set, just having a tech come out and eveluate the set may cost you a service call fee plus actual time in the house.

By your description it just needs the vertical ic chip and areas
resoldered & probably a god idea to do a quick ESR check on a few capacitors in the vert. 300$ to do that is robbery .. take the set to a shop where they are reasonable around 75 to 100$ for that problem . If you can solder you could do i yourself . Cleaning the lenses & mirror would be a good idea while its apart . |

$75 to $100 for a projection set, in your dreams.
Given the size, looking at an in home service call, around $50 to the door, plus around $125 labor plus parts typical. Well under $300 most of the time for that type of failure. $75 to $100 is not even enough to stay in business. David "Ken G." wrote in message ...

IMHO: you still have an 11 year old product with all of it's probability of
failure. Yes they were a very reliable product, so was the Edsel and Corvair?? "David" wrote in message ... $75 to $100 for a projection set, in your dreams.

David We have a guy like Ken in our area, who works out of his house, has an old beat up truck, crappy scope, decent meter (but nothing else), and lives in a very modest home. His wife makes excellent money and benefits (for both), and he has the nerve to call the professional shops crooks for charging $250 to repair big screen TVs. By now, between his using crappy generic parts and blowing off appointments, his reputation is crap. The problem is that this unprofessional guy is staining the whole profession by association.

We have a couple of those here, too. Can't count the times that I have had
to go behind them and fix things that they just leave because they don't have the skills, equipment, documentation, or will to deal with much more than cold solder joints. I have no problem with someone like this supplementing their income, but when they have to do it by trying to make legitimate businesses look bad with lies and half-truths, and when they make the profession look bad in general, there is no justification.

I'd rather not junk the TV as it was given to me and I don't have $3000 to go blow on a new one. I'm confortable with spending $200 on something that might last me for another few years. I'm not by any means an electronics guru so I think soldering is out of the question, but at least I understand what may be wrong with it. Last night, I opened up the back panel to take a look and didn't see anything out of the ordinary (blow caps, etc). The thick wires leading into the "caution high voltage" part scared me a little. Didn't want to get my hand in there. ;^) On a side-note, can anyone recommend a reliable projection TV repair shop in Cincinnati? Thanks!
