TV turns itself off?


I am sharing four cases in which your tv either turns itself off or appears to turn itself off.

TV appears to be off
  • You using your tv as a monitor or your pc is in sleeping mode.
  • Your cable or satellite Box is not outputting a signal.

TV turns iteself off
  • The sleep timer is set.
  • The off timer is set.

Your tv appears to be off:

If you are using the tv as a monitor If you are using tv as a monitor and the stand-by light only
blinks for a few seconds when you press the power button,your pc is in the sleeping mode. To take your pc out of sleep,press a key from your key board or move the mouse.Tv turns on.

If you are using TV with a cable or satellite Box

If you have a cable or satellite Box your Tv may appear be off because the cable or satellite Box is not outputting a signal.Press the guide or info button on the cable or satellite Box remote control.

if the screen displays info or guide data,the problem is caused by the Box,you must call your cable provider.
if screen does not display info data,change the source on your TV.

While watching, screen went black. Cable listings are showing but now screen! What can I do?


If you have a seperate cable box (not using the cable card in the TV) and you are seeing your cable listings (the Guide on the TV) there is nothing wrong with the Television. it sounds like the cable box is not decoding the video anymore, or you are having a cable outage. I would call your cable provider

Screen is blank but can hear all the channels. cable guide shows up but no picture. What do you think the problem is


The video circuit section of your LCD needs service and this will require board level troubleshooting and by a qualified service tech. There is a light tube or floresent tube that excites the liquid crystals to give visual to the screen and it may have blown and needs replacement.

TV Guide System not working


In order to receive the TV's Guide system, the cable should be connected directly to the TV instead of the cable box if you are still using it.

Scenium DLP quit recognizing cable signal


You may have inadvertently pressed some buttons on the remote to take it out of the mode to receive cable channels.
If you unplug the tv from the wall for a while, it may clear the error.

Step 1: Identifying Your TV’s Location
1. If your country is highlighted, press OK on the remote control.
If your country isn’t highlighted, press the up or down arrow button on the
remote control to highlight your country and press OK.
2. Use the number buttons and/or the arrows on your remote to enter your
zip code or postal code. Press OK when you’re fi nished.
Note: If your postal code contains letters, press the up and down arrow
buttons on your remote to enter letters, and press the right arrow button
to go to the next space. The left arrow button also moves the highlight to
the left.
Step 2: Confi guring for Cable
The next series of screens asks you about your cable setup. To supply your TV
with the correct TV program listings, the TV Guide On Screen system needs to
know if your TV is connected to cable.
Note: If you’re using a cable box, always leave it on so you can receive
program information.
1. If your TV is connected to cable, highlight Yes and press OK.
If your TV isn’t connected to cable, highlight No and press OK. (STEP 3:
Confi guring for Antenna
appears–go to page 24).
2. If you have a cable box connected to this TV, highlight Yes and press OK.
Note: The next series of screens is very important because the TV Guide
On Screen system must fi nd the correct cable box information in order
to receive the correct TV program listings.
If you don’t have a cable box connected to this TV, highlight No and
press OK (STEP 3: Confi guring for Antenna appears–go to page 24).
3. Highlight the input where you connected your cable box to the TV, and
press OK.
If you select Cable Input, continue to step 4.
If you select any other option, go to step 5 on the next page.
Important Note: Your cable box can’t be connected to ANTENNA
INPUT if it is to be controlled by the TV Guide On Screen system.

try using the guidelines above.
