Or it might be that the VCR has a very high RF power output, or it could be that the kid's TV has a very sensitive receiver.ĭee said that they lived out in the bush, so that means they probably don't have a lot of other electrical RF noise around, to muddy up the weak RF signal coming out of the back of the VCR. A common way to adjust tracking on your VCR is to press the Channel UP or DOWN controls, either on the VCR or on its remote control. Or the signal could be leaking out of a cheapo, poorly-shielded tin can in the back of the VCR. The RF signal from this tin can could leaking out through the cheapo, Original Equipment cable that joins the VCR to the TV. This RF signal should not leak out, but in this case, it probably is leaking out. It usually broadcasts this signal on VHF channel 0 or 1, or on channel 36 UHF. It doesn't transmit a massive 100,000 watts, but a very puny signal somewhere between one microwatt and 10 milliwatts. That's the RF modulator, which is basically a miniature TV transmitter. Once on, change the tracking control from one extreme to the other while playing the tape. Please ensure your TV is set to input that corresponds with the STB connection. The light on the STB will go off once the power is removed. Please Note: The power cord is a thin black cable. Remove the power cord from the back of the STB for 5 seconds.
#Vcr no signal on tv manual
Another thing to try with manual tracking is to turn it on. Bypass any extra devices such as your DVD player or VCR and connect the STB directly to the TV. If you look through the air vent holes at the back of the VCR, you can see a little tin-can thingie. Look at the manual for your VCR and turn off manual tracking. It connects to older TV sets that have no video/audio inputs. The second output of your VCR is the thing called the "Modulated RF Output". That's probably NOT where the leakage is happening. You normally connect the video and sound output on the VCR, to the audio and video inputs which most modern TV sets have. The first one is just a raw video and sound output, that leaves from RCA sockets. Video recorders can send out two signals. How was this so? Probably because the kids' TV set was picking up a TV signal leaking out of the VCR. (You will need Real Audio which you can download for free)ĭee from Western Australia wanted to know how come her kids could pick up a picture from her VCR, on a TV set that wasn't even connected to the VCR. I can record the video, timer and all of that. I tried newer rca cables, and also another input on the TV set, still no sound, just picture.
When i go to the vcr input on my TV set, I am able to see video, but no sound. Listen to Karl talk about VCR Transmitter I am at my wits end.I have a vhs vcr hooked up to my TV lcd set via rca cables.
