How to fix a grainy modulated channel on Channel Vision Stereo Receiver?
- I
  Isaac ColonNov 23, 2025
  If you observe a grainy modulated channel but the cable channels have a good picture on your Channel Vision Stereo Receiver, try these steps: Disconnect the cable channels from the system and check the modulated channels. Use a low pass filter to 'clean up' the incoming frequencies to be modulated. Evaluate signal loss of modulator through the splitters and cable length of the system. Check the connections between the modulator and the combiner for leakage or if the cable braid is touching the center conductor. Ensure the attenuator adjustment on the back of the modulator is turned to maximum output power. Check output strength with a field strength meter. Connect the modulator directly to the TV and check the picture quality. Verify the bandwidth of all splitters and amplifiers for 1GHz c...

Why are my local channels grainy with my Channel Vision Stereo Receiver?
- R
  Robert BrownAug 23, 2025
  If you are experiencing grainy local channels but the modulated picture is good on your Channel Vision Stereo Receiver, the issue may be due to signal degradation from the combiner. Try disconnecting the modulator and connecting the local channel feed directly to the distribution system to check the TV picture quality. Consider using a CVT-15PIA to compensate for the insertion loss. Alternatively, use a 6dB tap as the combiner, placing the local channel feed on the pass-through port for minimal signal loss and connecting the modulator to the tap-off port. Also, inspect for bad connections or leakage where the shielding braid might be touching the center conductor. Installing a CVT-15PIA amplifier on the incoming cable before the combiner may also help.

What to do if Channel Vision Stereo Receiver has black picture and no modulation?
- A
  Anthony GrahamAug 27, 2025
  If you're getting a black picture with no modulation on your Channel Vision Stereo Receiver, verify the connections to the modulator from the video source (e.g., VCR). Check the video source (VCR, Satellite Receiver, etc.) by connecting the outputs directly to the video inputs on the TV to confirm it's working. Ensure the video source has power. As a test, disconnect the modulator from the system.

Why is the modulated picture too bright on my Channel Vision Stereo Receiver?
- D
  Diana TaylorAug 27, 2025
  If the modulated picture on your Channel Vision Stereo Receiver is too bright or washed out, try the following: Slide the impedance switch to the 75? position. If your modulator is a CVT set-top style, adjust the video level adjustment potentiometer on the bottom of the chassis. If you're using a camera, check the lens positioning to ensure it's not aimed at the sun or a reflection. Adjust the camera lens as needed.

How to fix a modulated picture that is too dark on Channel Vision Stereo Receiver?
- D
  dawnweissAug 29, 2025
  If the modulated picture on your Channel Vision Stereo Receiver is too dark, try these solutions: If baseband video is being split with a Stereo Loop Kit or loop through quad, set the impedance matching switch (termination switch) to 1??. If your modulator is a set-top style, adjust the video level adjustment potentiometer on the bottom of the chassis. If the video source is not being split, check the input source directly into a TV. Adjust the video level adjust pot on the chassis of the set-top units to the proper brightness. Check all connectors for 75? impedance.

Why are low channels wavy but high channels good on Channel Vision Stereo Receiver?
- E
  Eric NormanSep 23, 2025
  If you're seeing wavy vertical lines on low channels but high channels are good with your Channel Vision Stereo Receiver, unplug the modulator. If channels look good, the problem may be beat frequencies or unbalanced cable vs. modulator. Decrease modulator power by adjusting the attenuator (red knob on back) or use external attenuators before combining it with the cable TV signal.

What causes picture tearing on Channel Vision Stereo Receiver?
- D

  If the picture is tearing when using your Channel Vision Stereo Receiver, it may be an impedance problem. Check that the impedance switch is set to 75?.

Why are low channels good but high channels grainy on Channel Vision Stereo Receiver?
- A
  Andrew BowenSep 18, 2025
  If low channel pictures are good but high channel pictures are grainy with your Channel Vision Stereo Receiver, place a tilt compensator in line after the amplifier and increase the amplifier gain until the higher channels look good. Check the frequency specifications on all splitters and amplifiers in the system.

How to fix flashing at the top of TV picture with Channel Vision Stereo Receiver?
- P
  Patrick GibbsSep 8, 2025
  If you're experiencing flashing at the top or middle of the TV picture with your Channel Vision Stereo Receiver, and the flashing is on modulated channels, turn up the attenuator/down the gain of the modulator. If the flashing is on local channels, turn down the gain or attenuate the output of the amplifier. You can also install filter #3102-78 to clean up the channels.

  Robin GarrettSep 5, 2025
  If the audio is too low on your Channel Vision Stereo Receiver, use a Y-Connector to combine the left and right audio before it enters the modulator.
