I purchased a 54" Maganvox rear projection TV (model #6P5435 W101) in
June of '97. It was a floor model and I've never had a lick of trouble with it. However, lately the picture appears to be getting dimmer, with people in dark scenes appearing as silouettes. I removed the screen and cleaned the dust off of the R, G and B lamps (crt's?) and that did not help much. Is it possible to replace these lamps? Is that what the problem most likely is? Is this cost effective to do myself or to have someone do for me (I'm a computer tech, so I'm comfortable with electronics, but not much experience working on monitors/tvs). Am I better off replacing it? I know I can get a 55" wide screen Philips at WalMart for around $1500. I'd like to get another 4:3 TV but it seems no one sells them anymore. Without any HD or having to purchase an HD tuner, it seems premature to purchase such a beast unless someone likes to watch letterbox movies all the time. Also, the inability to record HDTV broadcasts (at least affordably) has me completely turned off to HDTV for now. Advice? Also, are there better 55" (or larger) TVs available with a better picture than Philips/Magnavox that sell for less than $1800? (I've owned Magnavox and Sanyo TVs my whole life and never once had a problem with any of them, but I also realize they don't provide the best picture in the world...but then, I've always been happy with the picture quality with them...) Thanks! Carey |

Two possibilities: Bacteria has grown in the crt coolant or the
picture tubes are at the end of the life and getting darker. As for you replaceing them, not likely. Replacing Philips picture tubes requires new coolant and seals and full disassembly. Add the cost of the tubes, around $220 each times three, and it is not worth having it done usually. I'm betting on you needing to call someone out to pull the tubes, drain the coolant, disassemble and clean the bacterial gunk off the glass and refill. Shouldn't run more than $300 and you should get a few more short years of use out of the set. Lastly there is a slim chance of an actual parts failure causing dark images, in which case the set still will need looked at by a qualified technician. |

Thanks for the response. I called one repair shop who thought the fluid
needed replacing and that it was common in a Magnavox. They wanted $470-$480 to come on-site and do the repair. I'll call around tomorrow and get some other quotes. Thanks again!

Good to know! How much do you estimate this should cost me?
Thanks, Carey "Shoreline Electronics" wrote in message . com... Look down inside each tube when the set is on ( be careful!) You should see a crystal clear red , green and blue image from each tube. If it looks like a cloudy mess, the chambers will need to be drained and washed out and refilled. Typically the green and blue CRTs suffer from this problem...the red is ok most of the time. Picture will look like new after this is done! Worth the investment! Make sure they pull the power supply/sweep module and resolder all the transformers and heatsinked parts! -- ========================== Jeff Stielau Shoreline Electronics Repair 344 East Main Street Clinton,CT 06413 860-399-1861 860-664-3535 (fax) ======================== wrote in message ups.com...

We charge $379.00........I don't think you'll find anyone doing this for
less than $300. -- ========================== Jeff Stielau Shoreline Electronics Repair 344 East Main Street Clinton,CT 06413 860-399-1861 860-664-3535 (fax) ======================== "Carey" wrote in message ...

Just the turkey baster crew. The guys that suck out the old coolant without
disassembling and properly cleaning them don't know about the crap coating the inside of the lens and how much difference it can make to clean it right. We charge $390 in Gainesville, Fl.
