I have bought two different RCA receivers in the past week and both receivers have the same problem. Or at least the same problem is occurring. A channel will be doing fine, then all of a sudden the colors on the tv will slightly dim, then brighten, dim, then brighten. Very lightly, you have to really be watching to notice it. It is bugging me bad! Can anyone help? Could it be something in the coax? Please let me know. Thanks

Are you connecting the receiver into the back of a VCR first i.e. video and audio and not a a/v receiver?

Yes, it goes from the sat. receiver then to the VCR, then to TV. All thru RCA Cables. The only coax is the one coming in from satellite to the receiver? Is this a problem?

You may find that if you remove the VCR from the chain the problem will go away.

Ok, i took the VCR out of the chain completely. But it is still doing it. This thing is going out the window!

Well if you must, but i don't think that will fix my satellite problem.

Sounds odd; must be defective or you're getting bad reception.

I was thinking defective too, until I took it back for another brand new one. You think its possible circuit city just got a hold of a bad batch of em'?

I would consider a good power filter if you don't already have one. When I replaced my regular $20 power strip with a good power regulater/filter strip, it did wonders for a lot of the consistancy issues with my TVs picture.
Good luck!

What TV do you have?

Zman I have noticed the same thing on my RCA dish (5451)but only at certain times so asumed it was just a clitch in the signal decoding. Have you noticed whitch channels or is it all of them?

This is on a Sony 35" Trinitron TV. Everything is plugged into an old cheap power strip. The fluctuating only usually happens on certain channels. HBOs do it, NBC, and some others. Im going to try a good surge protector after work and let ya know how it goes.

The funny thing is, I had an OLD OLD OLD RCA receiver, the first ones, and it never did this. Nothing has changed, i unhooked that old thing, and hooked up the new one, maybe these are more demanding as far as power goes. Well see.
