I initially used a code to hook up my new westinghouse tv, for basic channels, using the coaxial option. BUT I just got a new cable/DVR box today and i need to put in the code for it to work on my tv. I believe I already have the correct code but I need to know the process of putting in the new code. I have a LD-4655Vx tv and I believe the new code I need to enter would be 69333...

go to the Menu and you should find it.

Cable signals today are encrypted so that it is not possible to directly connect the cable to the set and get the cable channels. You must use the cable box. Some sets have what is known as a "cablecard" slot that can be used with a card from the cable company in lieu of a cable box. Only then can you use the TV tuner for cable channels.

If you are receiving a "No Signal" error message, verify that:

1. All of the cables physically connected to the TV and the input device are secure.
2. The input device is turned on.

Your TV needs to scan for channels before it can show programming from an antenna, from cable TV when the cable comes directly from the wall (no cable box), or from a cable or satellite box connected to the TV with a coaxial (RF) cable. Do not scan for channels if you have a cable or satellite box connected using AV (Composite), Component, or HDMI cables. The box selects the channel, not the tuner inside your television. If you are not using the "TV" input, press the INPUT button on your remote until the correct input mode is selected.
To perform a channel scan using the coaxial input:

1. Press the INPUT button on your remote to view your current input source. The TV (coaxial cable) input must be selected. This may appear as "TV," "ANT," or the channel and call letters of a station.
2. If the TV input is not selected, press INPUT until the TV input mode is selected.
3. Open the on-screen menu and select TV or Tuner option. (This varies by model.)
4. Highlight Tuner Mode and select the correct option:
   • Antenna-over-the air signals from an antenna
   • Cable-direct from the wall cable TV, or a cable or satellite box connected to the TV with coaxial cable
5. Select Auto Search or Auto Channel Scan. (This varies by model.)
6. When the search reaches 100% complete, exit to the menu.
7. Check the available channels:
   • Antenna or direct-from-wall cable-Press the Channel Up and Channel Down buttons on your VIZIO TV remote to view the available channels.
   • Cable or satellite box- Will return only one channel. Use the cable or satellite remote's Channel Up and Channel Down buttons.

If this does not resolve the issue, power cycle the TV and then re-run the channel scan:

1. Turn off the TV.
2. Unplug the TV from the electrical outlet.
3. While the TV is unplugged from the wall, press and hold the Power button on the TV for 30 seconds.
4. Release the power button.
5. Plug the TV back into the electrical outlet.
6. Turn on the TV.

Note: There is also an option to reset the TV to the factory default settings. This option is in either the SETUP or SYSTEM section of the on-screen menu. The option may be "Reset all settings", "System Reset," or "Reset & Admin." Consult your TV's user manual for the location and steps for resetting your model.

1. Remove the coaxial cable from the DTV/TV connector on the back of your television and perform a channel scan to clear the existing channels. See the procedure above. This should not find any channels.
2. Re-attach the coaxial cable to the DTV/TV connector and perform a new channel scan.

This video shows troubleshooting steps to use when a "No signal" message appears.

Why not get a box and hook via rear inputs--not that expensive from most cable companies. If items such as the channel scan are grayed out it means something in the set is set wrong---

U getting the DVR box signal into the tv channel 3?Yes,don't use the tv remote,used the DVR romote as ur remote.

Try this set up-

Use an RCA audio/video cable for this set up (Yellow/Red/White).

Connect from the Video out (Yellow) connection on the back of the cable box to the Video in on the back of the DVR.

Connect the audio (Red/White) cables from audio out connection on the back of the cable box to the "Audio in" on the back of the DVR.

This should still get you a decent picture but not a true HD picture for your recordings.

When you set the timer to record set it to record either E1 or E2 depending on which input you connected the cable box to and ensure that the cable box is tuned to the channel you wish to record.

*** NOTE: If you keep the HDMI cable connected as you have for the cable box and watch normal TV through the HDMI input on the TV you will get HD programming for your general viewing but still have the option to record with the DVR at a lower quality. ***

Good Luck and please rate this solution....

Please do the Auto Channel Program once again and let me know.

It sounds like your TV is on a different input. If you watch your cable from an external cable box, and this box is plugged into your TV using wires that are yellow, red, and white, or red, blue, green, red and white, you're currently watching TV on a different input than the one used for the antenna. Channels in a TV are controlled by the tuner. The tuner is the silver, threaded, post on the back of a TV, DVR, converter box, or VCR, that you plug an antenna or cable wire to. The tuner contols channels while the other inputs on your TV carry a direct signal like a computer to a monitor. So when you use something other than coaxial cable to connect cable to your TV, you can't access the channel menu while on that input. To access that menu, change the TV's input or source to TV or stop when you see a channel number on the screen. You have to be on the TV or tuner input in order to access the channel menu. If you're on any other input such as, S-Video, AV1, AV2, component (Yp Br Cr), HDMI, etc. you will not be able to do a channel scan. You have to be on the right input or source.

Take your TV for a check by a good technician. Some IC have short circuited in the accident that occured.

After basic cable box hook-up with coaxial to TV, the next step
is to select channel 3 or 4 on the TV because most source boxes send out their signal to one of those channels.
An alternate hook-up is to plug-in yellow,red and white from the
cable box to the same colors on the TV, then select video input
on TV...................Let me know if you need more info......T
