Some Help Needed with a Old Rear Projection Magnavox
I need some advice and some info on where I can find some parts. OK I got this TV free from my grandpa last summer after he upgraded to a 56" HD Sony I have just recently got around to messing with it due to moving, so anyway I was wondering where I might be able to pick up a new screen for this thing. The current one is has tons of scratches in it and its a little warped. And I also have a problem a little hard to explain. When ever I use the TV to play a DVD or Video Game there is a Ora around the Character and text the color on said Ora depends on the color its surrounding and the brighter the color the larger the Ora gets. I am trying to get at least 2 more years out of this TV giving me time to save up for something better. My grandpa bought this TV new in 92. Any advice and help will be greatly appreciated. Thanks in advanced.
TV Info: Make: Magnavox Model #: RM8540 A103 Serial #: 11237205 Pack Date Code: 3011R091D Chassis Model #: PTV382-A001 |

Rear projection televisions generally should be adjusted and viewed in a darkish room, as they can be a bit hard to see in a bright room. Try setting the contrast full, then the brightness to a level where black areas in the picture actually look black, and then back off the contrast to around 80% or whatever looks best to you. |

I believe you mean aura (luminous radiation), which surrounds bright object. If the set is 13 years old, and belonged to your grampaw, its probably never been serviced. Removing the screen, and washing 13 years of dust, smoke, and whatever off the mirror and the top of the crts will probably eliminate the aura, or halo. As to a new screen, good luck. I suggest you save your money. This unit is past its prime. Deke |

Needs a complete mirror and lens cleaning AND all the coolant needs
replaced in the picture tubes after they are disassembled to clean the growth of years of crud that is on the face of the tubes. Strongly recommend you have someone do the job who has access to all the training, parts, and experience to do the job properly. Typically under a $250 total repair depending on how badly the adjustments have been screwed up. David |

Thanks for all the responses guys, I am going to call up a few places in the yellow pages to get a estimate on a Full Cleaning and Coolant replacement. If its under 300 I will be fine. I also posted this at tv-forums.com where I was told it was most likely the coolant in one or all the tubes. I have no other problems with the TV the convergence is perfect, the color is great, its nice and bright, and the picture is Great except for the aura. Thanks Again Guys.

Send the measurements of the screen, I have a few kicking around.
It also may be ready for a coolant change. JURB |
