Question about LG Televison & Video

Open Question

My LG LCD 32LS3400 keeps turning off by itself. It goes through a process of turning on and off. Sometimes it continues this cycle until I unplug the power supply from the back and plug it in again.

LG LCD model # 32LS3400. Bought new. Plugged into the outlet and not a power strip. We also have a Comcast digital cable box.

SOURCE: HDMI connectivity

I have the SA8300HDC STB from Time Warner. I get this error from my DVD recorder, not from my HDMI connection. I've read that the error is due to copy protection. The only solution I've read about has to do with a new Samsung Set-top box from TWC. Funny this copy protection error didn't ever come up with my old VCR connection to the HDTV. TWC apparently told a lot of people that the problem would be solved by a software update from TWC in October 2007 & then in December 2007. Guess TWC isn't sure what the problem is but everyone who has mentioned this Samsung cable box has reported success with their HDMI connection.

Replacing the cable box may fix the problem. But, you're the 4th person to have this same problem with this SHARP TV MONO only audio.
Try system reset button on the back of the TV or the box.

HAD A POWER BLACKOUT TODAY NOW TV DOES NOT TURN ON, HAS NO POWER


If you didn't have it plugged into a power surge strip, you may have blown the tv. Write it off on your taxes next year and buy a new one. If you do have it plugged into a power strip check to see if the lite is on/then if not push the button to reset it. That should do it. Also, same with your satelite/cable box.

I have a comcast digital converter box and i need the manual to hook it up to a tv


Here is the easiest way...

1. Connect coax cable from the wall to the "Cable in" on the cable box.

2. Connect a coax cable from the back of the TV to the "To TV" output on the back of the cable box.

3. Tune your TV to channel 3

4. Plug the power cord into the back of the cable box and into a power outlet.

5. If you do not have a picture call Comcast and ask them to send a signal to activate your new box.

6. Enjoy your new programming.....

Good Luck...

Try resetting the TV by holding down the "up" button on the remote (with the TV powered on) and then, while you hold down the up button on the remote, hit the power button on the TV. This should do a "factory reset" which will wipe all settings in the TV. There is no reason why the TV should not "remember the last input it was on when it was ;last turned off. Also be sure that the TV is not plugged into a switched AC outlet, like the outlet on the back of the cable bix. The TV should be plugged into an output that receives power at all times.

No sound on NON HD channels


I had the exact same problem on a brand new Insignia 26 " LCD with DVD. Comcast tech was able to fix it by changing the Comcast box diagnostics. Here is what he did. Using the Comcast remote with the TV on - press power, cable, menu in that order. A comcast diagnostic srceen will appear. Select Additional HDMI options, then audio options. Change the audio options to L-PCM. Press power again to exit the diagnostics. That will fix it and you get to use the HDMI cable.
