Hello,

9 out of 10 times, the problem is the device that is hooked up to the TV, and not the TV itself. This is especially true in the case of cable boxes, which have a long history of failures.

Temporarily, you can probably hook up the composite (yellow red and white) cables to get a picture and sound on a different input.

You can try to hook up a DVD player on the inputs (component, I'm guessing) and it will probably work. Then you get to call the cable company!

Hope this helps...

Cable TV blinks on and off when connected to my Onkyo receiver.


I have the same problem.  It only occurs with my HD DVR (HDMI cable), not my blue ray (HDMI cable), or my xbox and wii (component video).  Video and audio cutout is random and drives the family nuts.  I am desperate for a solution.

Go video model dv-241 hook up to make vhs to work


There are a fews ways of accomplishing this.
It sounds like you may reversed your cable connections. Lets try these steps.

On the back of your cable box and your Go video VCR/DVD there are two coxial connections an (OUT) and an (IN):

Step 1. Connect the coxial cable from Comcast to the (IN) connection on the back of the cable box.
Step 2. Connect one end of a spare coxial cable to the (OUT) connection on the back of the cable box.
Step 3. Connect the other end to the (IN) connection on the back of your GO Video box..
Step 4. Connect one end of another spare coxial cable to the (OUT) connection on the back of your Go Video Box.
Step 5. Connect the other end of the Coxial cable to the back of your TV.

I hope that you find this solution helpful.

I have an old Zenith Digital Surround System the Receivver is a Model Z763B with a DVD Player/Recorder connected. When I play a DVD or VHS the sound can be heard through the TV and the Sound System,...


I have the same A/V receiver and in my setup there is an audio output (red and white able) coming from DVD player directly into Zenith Z763B. The video from DVD Player goes to TV input (yellow cable).
There might be alternatives to the setup mentioned above but I like to watch movie in a surround sound, rather than output from TV.

Channels won't come in


Hello divalisaf,

These are a few things I want you to check first.

1) Make sure the cable set top box is on and the cable is connected to the TV properly (This may seem simple but I have had to charge many people a $60.00 service fee plus a $70.00 travel fee just to turn on a cable set top box)

2) Make sure the TV is set to the proper input you are using (RF( F connector) , HDMI, Component video, and or Composite Video)

3) Make sure the TV is set to the proper channel (either channel 3 or channel 4 depending on your area) The cable set top box should be action as your tuner.

If all of these conditions are met, then we can begin troubleshooting.

First determine if the other inputs work (HDMI, Component video (RGB), Composite video (yellow), s-Video (6 pronged black cable).
If the inputs work then you possibly have a tuner problem
If the inputs don't work then then problem is likely in the video microprocessor.

If the problem is in the tuner or the connective circuitry then we will have to determine where to get a replacement tuner (or you can just use one of your other video inputs)

If the problem is in the video section (which includes the microprocessor) we are going to have to troubleshoot the video section which will involve you having a background in electronics, if not I would suggest having a qualified TV technician perform service on this TV.

I hope this helps,

Thank you,

No Video for my cable tv. Audio works


You have the TV connected to the cable box with an HDMI cable, I'll bet. The problem is with the cable box. If you unplug the cable box and plug it back it it will reboot and proabably work. You should connect the cable box to the TV using component cables and you won't have this problem again.
