While I cannot diagnose via usenet, if there IS a history of these blowing the center channel, I would look very closely at solder connections relating to the bias transistor. This is the type of thing that might cause such a history on a given model type. The advice given on the relay is good if the channel volume is merely down or especially if the volume is intermittent and comes back with an increase of the volume control setting or as he said with tapping the relay body.

thekmanrocks@gmail.com: Jul 16 06:18AM -0700 Alright, Mark Z, et al: I've discovered that I can get center channel - for a while - by moving the speaker wire around in the center ch connector on the receiver. Last night I stripped off an extra long length of wire, so as to bend it over to double the thickness. That worked - last night. This morning I turned it back on, and got center for about ten minutes before it cut out again. I fiddled with it some more, and discovered that by having the speaker wire(16AWG by the way) *barely in* the connecting terminal, with the locking tab left up, I get center pretty consistently. If I pushed the positive in all the way - NO center. If I jiggled it - intermittent center. So we'll see how long it produces center with the positive barely hanging in there. Different times of day, the center works, other times, not. My original RX-515, which is still in my cellar, is definitely blown center, at the component level. No amount of jiggling or doubling over the copper strands is gonna pass sound through the center speaker with that thing. And the sad part of all this is JVC is OUT of the home audio business! Here they had a great mid-price surround-sound receiver for mid-1990s, ample power, connections for TWO tape loops(great because I have an EQ on one and my tape deck on another), and a phono input. I couldn't give two shits about HDMI inputs, bluetooth, and X.1 digital surround if I can't hook all of my analog gear up to it!! So I'm going to buy every remaining RX-515V out there, at least just for parts interchangeability. |

As well as the picture content, I guess in LCD TVs they lose a lot of light in the polarisers, on top of what is lost in the R,G,B filters. > processing.

You make a good point, some CRT TVs are quite efficient. Also I like the idea of having a particle accelerator in the living room. |

I dealt with the same model computer over the Christmas holiday. It is hard for me to imagine the video chip being a problem if the external video works. That being said, you are correct about MANY such computers having a video problem. I did the blow torch/ shield from the heat method, and the computer worked for about a day. Long enough to take all the data off the hard drive for the owner. To tell you the truth, I would not put too much labor into this model computer. Especially with it's history. You could be making a career choice. |
