Technical assistance, please
I am looking for possible solutions to the following problem: when viewing DVDs the picture quality degenerates going from normal to dark with qualities of a photo negative (light areas appear darkest, dark areas lighter) and then back to normal again. This happens in a nearly continuous cycle which is obviously annoying.
Potential clues: *Regular television viewing does not have this problem *Video cassette viewing does not have this problem. *The DVD player is routed through the VCR (via RCA cables) *I have replaced the co-ax cable from VCR to TV (no effect on the problem) Ideas? |
Connect the DVD directly to the TV....linking the VCR through the DVD and other aux components? :hmmm:
|
I am also just now noticing that the RCA cables (from DVD player to VCR) are bundled. Could this affect the picture quality?

Are you referring to the RCA cables that came with the player?
Also how big is your TV? ~ Sounds like a bad DVD player. |

The TV is probably a 19" |
Why in the hell are you using RCA cables to attach a DVD to the TV? Don't you at least have SVideo?

Actually do what SDChiefsfan said but dont hook up anything else to it. You are trying to troubleshot the DVD so once you have figured it out you can place everything back to normal.
Depending on your TV try an S-Video connection or if your TV has it the RCA video connections. What you are trying to do is isolate your problem. I dont know how you have the DVD hooked up to the VCR but either the DVD is at fault, The wiring from the DVD to your VCR is at fault or the Connections on the VCR are at fault. By going direct to the TV you remove the VCR from the equation hope that helps |

You may have to go to another video input on your tv set. Normally the RCA jacks are Video 1 input or something like that. The Coax is setup to be the primary connection. See if you have a menu button and can change inputs.

Bummer. I'd head down to best buy and apply for a card. ;)

P.S. If the original problem is gone, what does that tell me? The VCR is defective? |

Hmm. Good news: The original problem seems to be gone. Bad news: After re-connecting the co-ax cables (from VCR to TV) the TV no longer seems to recognize the VCR input (via coax cable).

Unless there are clearly identified specific ports for EACH.... :hmmm: |
Turn your TV to channel 3. Or verify you haven't bent over the copper core in the coax. I did that a couple weeks ago on some coax.

The TV is not that old, about 5 years. The remote is gone but I'm not sure that is the problem. I can now get decent quality with either the VCR or the DVD player but the quality degrades if both are plugged in (even when the DVD player is routed through the VCR). I don't know. I'm off to sleep. Thanks for the help so far, I'll check this thread again tomorrow to see if there is something I have missed.
Goodnight, all. |
I have the same problem with a dvd player connected to my TV/VCR combo in my bedroom. The TV doesn't have RCA jacks, so I'm using a converter so that I can connect through coax. I always just assumed that it was the converter.

The reason for the change in picture quality is the macrovision copy protection on the dvd. Your vcr picks up this signal and reduces the quality of its output to prevent you from making vhs tapes of your DVD's. You should connect your dvd player directly to your TV. There are "black boxes" available that you can your signal through to get rid of the macrovision, but those are 40-50 bucks.

It'll do the same thing to TV/VCR combos. If you want VHS and DVD at the same time and are limited by the number of video ins you have on your TV, you'll have to buy a DVD/VHS combo. You can get them at Wally World (Wal-Mart) for $100 or so. Otherwise, get a switcher if you don't want to get a new TV.

You have to run direct to the TV. Running the DVD player through the VCR activates Macrovision copy protection, which is the degeneration you see, even if you aren't recording.

Has anyone suggested this yet?

Also, you may have brushed the channel selector switch on the VCR, and the VCR coax signal is now being sent to channel 4. |
