I have a strange predicament...
I recently bought a Syntax Olevia 37-inch LCD HDTV (LT37HVS). When I hook up my Panasonic VCR via composite inputs, the TV cannot detect the VCR ("no signal detected"). The particularly strange thing is that if I use the TV's Picture-in-Picture function, the VCR works, but only in the small PIP frame. When I try to switch it to the bigger frame, it goes blank and says "no signal detected" again. I know that the TV's composite inputs work because when I hook up my DVD player to them it works fine. I also know that the VCR works because it was fine on my former 32-inch CRT tv. The VCR only has composite outputs, so I can't try another type of connection. I called Syntax tech support and they had no answer other than, "it sounds like that VCR is incompatible with our tv." Does anyone have a more specific idea as to what the problem is? Thanks. M |

M Interesting. Could it be that your TV is particularly susceptible to Macrovision signals on the tapes? Does this happen with your own recordings or just pre-precorded factory tapes or both? Connect a different VCR and see if that one works with this TV using the same tape(s) in question. |

Just for the heck of it, try rf out from the vcr and see what happens? Ken |

If it really has no RF out, it sounds more like a VCP than a VCR. Perhaps the OP meant it doesn't have S-video or component outs but does have RF out. shrugh |

Tried the RF connection-- same problem.
Then I tried a different VCR-- same problem. Why would a tv work with a dvd player but not with a vcr using the same connections? This seems to be the crux of the problem... Any ideas? Mike |

Mike Best case scenario: Ken is right and this is operator error Worst case scenario: you have a defective TV I checked the owner's manual for this model. The relevant pages start at page 47. Try setting the aspect ratio to 4:3 and the "view" mode to "OFF" (i.e., not PIP or Split). Set "Pic1" AND "Pic2" to "AV1" source mode -- and, of course, have the VCR connected to the Video1 inputs. If you still get the same results as before, try setting view mode to "Split" and see if you get half the screen showing the VCR video. If the above doesn't work and you bought the TV locally, take your VCR to the place of TV purchase and have a salesman demonstrate that your VCR does work with this model TV. Pay close attention to how s/he sets up the TV so u can duplicate it at home. Or.. if you got this via mail order, call Syntax tech support. If you can't get it to work despite these efforts, at least it's under warranty (I presume), so you can either exchange it or have it repaired free of charge. The only other thing that comes to mind is that the TV might be defaulting to PIP when it has trouble determining the proper resolution/scaling and mode switching -- e.g., progressive scan (if this is what your DVD player uses) vs. interlaced (your VCR). Since the TV should automatically adjust itself for this, one would suspect the TV is defective. |

No resolution yet. Based on a recommendation from Syntax, I exchanged
my Syntax Olevia for a new one, but the new set has the exact same problem. From everything I've read and various replies I've received, it seems that the problem is due to the VCR not having "time base correction". All my other components that are time base corrected (DVD, video camera) work fine. Apparently, these tvs are very finicky about this issue. I'm waiting to hear back from Syntax whether or not this can be fixed. I'll post back when I get a reply. wrote: a écrit : wrote: I have a strange predicament...

I am having exactly the same problem -- but only with some tapes. How can a VCR be incompatible. Did you get any resolution to the problem? |
