Hello,

the fault is from the cable box. The cable box must have received high current and has spoilt an IC on the board inside the cable box.

The board is not repairable most times but it can be replaced. Since power is entering into the unit, then its not a power problem.

Power is entering into the board, but the board is not bringing display because of the damaged IC.

So, I would advice that you take the receiver to a local repairer within your vicinity, if the board is replaceable, you can replace it, but if its not replaceable, then you will be looking forward to another receiver.

Try to always use a step down or stabilizer for your cable box, DVD player, etc, because the board in most of them are not usually strong. Also the board controls the whole unit, therefore if excess power enter into the board from the power board, it can damage an ic on the board.

Good luck.

This cable box has a long list of issues, most notorious is the HDCP compatibility via HDMI connection. Let's try to access the Setup menu first. With the TV on and set to the cable box input (I assume you are using HDMI): Turn the cable box off, press the "Menu" button on the front of the box. Does the box front display then read "16:9" or "4:3...". If it does and after a moment the TV does not display any video from the cable box: Use a single RCA cable and connect it to the green video jack on the back of the box, then connect the other end of the cable to a green component video jack on your TV. Switch the TV to input you just connected. If you do not have video, you need to replace the cable box. If you do have video, use the press the down arrow button until you are on the "HDMI advanced" menu. Press the "Select" button to enter this menu. Change the video output type to "RGB" and the Audio type to "L-PCM". Use the Right arrow button or the "Select" button to change the selected item. Once you have made these changes, press the power button again to exit the menu. Switch your TV back to the original cable box input. Press the power button on the cable box to turn it on. If you still do not have video, replace the cable box. These boxes are typically owned by your cable provider and are replaced at no charge. I hope this was helpful, best wishes,

Mitsubishi wd-73738 turns itself back on


Hi,

It sound like the remote is powering off the cable box but not the TV. The remote control may need to be reprogrammed to the TV. When you press power it may only power off the Cable box. At that point, try pressing the TV button on your remote and then Power. If it does not power off the tV after pressing the tV button, the remote may need to be reprogrammed to the tv. Cable companies usually have the codes needed to program their remotes to the TVs.

Televison station won't scan


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.

The unit comes on using the power button as well as a remote and displays "Polariod" on scrfeen and then nothing else, no sound no picture?/


More than likely your power supply needs two electrolytic capacitors, 10MFD @ 450 WVDC. If you find the capacitors on the power module to the top of the metal enclosure inside the tv, they will probably appear to have swollen tops.

My son bought an AOC LCD TV (model L24H898) last month and connected his laptop and XBOX to it. Yesterday we lost internet connection and the screen on the TV went blank. Now none of the button on the TV...


According to the manufacturer, to reset the entire unit do the following:
1. Press and hold "Menu" and "Channel +" on the TV. 2. Using other hand, press the power button. 3. A small screen should appear in the top left part of the screen. 4. Using the remote, select "Memory Recall" and select. 5. Power off and re-boot the computer 6. Run channel auto-scan to regain the picture.

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.
