I've had a TEAC JC-50 stereo for several years and it has performed without a hitch. I also have a TEAC CD player and VCR. A month ago I bought a new TEAC DVD (DV-2150), and yesterday in keeping with the TEAC theme, I bought a new TV (CT-M5150H). My set-up worked just fine with my old color TV, using the stereo for DVD audio amplification. But now I can't watch a DVD if the TV is on! The TV drives the amp crazy. This is one of those amps with touch-select buttons and whenever the TV is on, it cycles through the button settings - even turning the power switch on and off! It happens when the TV is up to 15 feet away (the limit of my audio cable length). It is not coming from the DVD. I hear clean audio when the DVD plays, but the moment the TV "on" button is pushed, the amp goes ballistic. There is no cable at all between the TV and amp. The only connection is the audio output from the DVD. At first I thought it may be due to some massive de-gaussing spike on TV switch-on, but it also happens in the steady state - i.e., TV on first and running, then switch on the stereo. It is normal for a second or two, then the crazy stuff begins. This happens even when there is NO cable connected to the DVD at all. So there's something coming from the TV. Can anyone help with suggestions on what I can do to fix this? I can't watch DVD's on my new TV unless I use the TV's mono sound system, which is pretty poor compared to the external stereo. Many thanks.
Follow Ups:
The Tv may be sending out infra-red signals to it's own remote control... and THOSE signals are affecting you amp. (this assumes the amp has an infrared sensor) My JVC VHS remote sends and gets signals from the VCR. Your new TV may be doing the same. Check in the TV manual and see if the remote receives any signals from the TV? I bet that is the problem.. not "Evil Gremlins".
"There is no cable at all between TV and amp. The only connection is the audio output from the DVD". The only connection to what? I assume from DVD to amp, right? Cause if you're running audio output INto the back of your new TV, that would explain a lot.
Something has to be running between your DVD and the TV. Is it component, composite or S-video cable? Clearly something basic, but very bad, is wrong with your hook-up. You've got to bootstrap the system, ie: take one cable out of the loop at a time (shutting down your amp every time), until you locate the bad hook up. It may be as simple as running an output into an output etc. But you can do a lot of damage like that.
Also, you might try setting up the system the way it used to be, before the added new stuff, to see if the amp still whacks out. You say you've had the JC-50 for "several years". You may be blaming the new TV unjustly. As George said, all things must pass. Then again, it can't be that old if you can run Dolby and/or DTS encoded audio signals through it, which is what you're getting off DVD, right? You say you ran DVD through this amp, with the old TV, and everything was okay, right?
Good luck. And this is a special case indeed. Please keep us posted?
[and I do NOT wish to giggle at your misfortune, but the quote of the week has got to be "now I can't watch DVD if the TV is on!"]
