Usually when the OSD will not come up, you are looking at a problem with the video boards. Is the power button flashing or showing a different color, or does it look normal in the On position. If it's flashing, then the problem lies with the mainboard not powering up properly. It might not hurt to try a power drain at least:


1. Unplug the product's power cable so that the device is not grounded to the house. Do not simply turn off the power-bar if one is in use.
2. Press and hold in the products power button for 1 minute to release the retained electricity from the capacitors and circuit board. 3. Plug the product back into the wall outlet rather than a power-bar to rule it out of contributing to the problem and turn the device back on.
If this doesn't work, the TV will likely require service.

Unplug everything from the wall-outlets, and from other devices, and then reconnect all the wires.

Also, try a different TV (some newer computer-screens have "TV-input" and/or "HDMI-input" sockets).

My SONY KV32FS13 DO NOT HAVE IMAGEN ON THE SCREEN NO GET ANY CHANNEL OF TV OR CABLE ONLY WORK WITH DVD EVERY TIME WHEN TURN ON COME OUT NO SIGNAL.


Try pressing Tv/Video on the remote control and see if it doesn't switch input modes. If it doesn't, follow these steps:

1) Press the menu button

2) Navigate over to Channel Setup

3) Move down to Video Label and select it

4) Make sure none of the video inputs are labeled "SKIP". If so then do the following

5) Highlight the input labeled "SKIP" and select it

6) Use the up and down arrows and you should see a different name for the input. This will enable the selected input to be used.

7) Exit the menu by pushing the menu button on the remote.

8) Press Tv/Video on the remote and you should see the other stuff (cable, vcr, xbox, etc.).

Plasma tv has no picture but green led is on


If you are not able to bring up the TV's onscreen menu while the picture is blank, then you have a problem with a video board.  If the menu does come up then usually the problem is with the device connected or its related input jack or cable that is in use. You may have to try another input or cable to be sure, but only if you are not able to see the menu.

Blue Screen in TV Mode


I have an Audiovox FPE1506DV with the same problem: it plays DVDs okay, but when I try to watch TV, it only shows a blue screen, but sometimes you can hear the sound. Cable input is fine.

When going through the Menu option in TV mode, the "Display" option is disabled; you cannot select it with the remote.

SOLUTION: I unplugged the device for about 5 minutes, plugged it back in, and it has been working fine ever since. It's a very strange problem, but rebooting by UNPLUGGING (not just powering down) seems to have fixed it.

Volume and menu does not display


I had this problem on my Aquos (LC-46D62U). It was NOT a hardware problem. I recommend turning off the television. Next unplug the television for 5 to 10 seconds. This resets something for the television. Plug it back in and turn on the television. You should now be able to get your volume and other on-screen displays.
