My dynex lcd tv keeps saying no signal when cable is plugged in?


It sounds like the CATV portion of the TV tuner is bad--Cable band.

You may have an option---with a cable box that has the audio/video jacks for output of signal on its rear side connect to a unused video input on rear of set--go to that input and change channel via the box---BY PASS THE TUNER IN THE SET THIS WAY.

How do I connect my PS3 to my sanyo dp50747 in hdmi? I have everything hooked up correctly, but its not coming up on the TV. What do I do?????


If you see a no signal message, then it means that the signal output format of the PS3 does not match . It happens if you have previous used it on another tv and now connected it to a different tv. To resolve this, turn off the PS3 . Press and hold the power button on the PS3 till you hear three BEEPS. The PS3 should automatically detect the tv's resolution and the initial setup screen should appear. After that you should just follow on-screen instructions to set it up.

I need the maual for this rca tv L37wd22yx6 tv just keeps saying unusable signal and i need the maual


What is the signal source for the TV? Make sure that you are on the correct input. Use the Input button on the remote. If you do not have the original remote, you need one that matches that function. (Often a Source or Input button is not available on the low end remotes.) Check that you have the signal set to Antenna or Cable if you are using the coaxial connection and the source is TV. (Menu > Setup > Channel Setup > Signal Type)

If your source is a computer, use the VGA port not the HDMI port. Computers send a different type of video signal than video set top boxes. The L37WD22 can't interpret the PC signal on the HDMI input.

For a set top box on the HDMI port, the unusable signal message indicates a communication issue. Try pressing the Info button on the remote. If you see an additional message of Acquiring Channel, then the set top box isn't responding to the remote. Check that the device is on and set up correctly to communicate with the TV. (For example, if your set top box offers progressive scan, try turning of that feature with the control for the box.)

The L37WD22 was built by TTE for the RCA label. The manual is available on the TTE support page.

The direct link to the User's Manual in English is http://support.ttetech.com/RCATV/Assets/pdfs/L37WD22_16788070_IB_e-07.pdf .

I hope this helps.

How do i hook up my ps3 with tv through hdmi as it keeps goin to blue screen


  1. Connect the PS3 standard composite video connector (yellow RCA plug) to the TV composite input and switch the TV to that input. Leave the HDMI cable connected.
  2. Make sure the PS3 is off. Turn it on and hold the power button until you get two beeps (at least 5 seconds). The PS3 navigation screen should be shown on the TV. If not, switch the TV back to HDMI; the screen should be displayed at 480i resolution.
  3. Go to the settings menu. Select Display Settings, then Video Output Settings, then press the X button on your controller.
  4. The on-screen instruction should be "Select the type of input on your TV." Select HDMI, then press the '> (solid right triangle) button on your controller.
  5. You will be offered the choice of Automatic or Custom settings. Try Automatic first (if there is a problem at the end, start over and pick Custom the second time).
  6. Press the X button. You will get a screen asking you to confirm the changes. Press the X button again to confirm.
  7. You may get a screen asking for the resolution setting. IMPORTANT: if your TV's maximum resolution is 720p or lower, do not pick a higher resolution. The TV may not display properly or may not display at all (blue screen). Pick the highest resolution your TV can display.
  8. Confirm this by selecting "Yes" and pressing the X button.
  9. The settings list should now read Connector Type HDMI; Resolution Standard (NTSC); 480p; 720p; 1080p (if applicable). Press the X button to confirm.
  10. You may be offered a choice of audio outputs; you can use HDMI or something else, depending on your setup. Confirm the setting and press X one more time.

At this point, the PS3 should send its signal to the HDMI port following restart. If your TV has more than one HDMI input, make sure you select the one connected to the PS3.

Tv has only snowy screen. Used the remote to


What to do if you have an all snowy picture (blue screen or the TV displays unusable signal-no signal or no sync)
1 – If you are using a digital cable box or satellite receiver (make sure it’s on) and be sure your TV is set for either CH3 or CH4 (which ever you usually view it on). If you usually view it through video inputs (video1 or 2 etc.) make sure the appropriate input is selected.
If you still don’t get a signal see if you get picture using the DVD or VCR (if available) if you do than plug the satellite or Dig. Box temporarily into the place of the DVD (unplug DVD) you may have to use some A/V cables (RCA yel./red/wht like the ones on the DVD) to hook to the tv from the sat./dig. box. If you get a signal then the sat./dig box is ok. If not the Sat./dig box is not sending a signal and is either defective or needs to be rebooted (unplug wait 5 min try again).
2 – If you are using standard cable or antenna (source) if possible check that the source is good by connecting to another TV. Otherwise try running the source into a VCR and then out to the TV using video inputs (RCA yel./red/wht like the ones on the DVD) and then selecting the appropriate input. Try seeing if the VCR plays using standard CH3 (or CH4)
If the VCR plays on video input but not when connected to CH3 (CH4) then the tuner of the TV may be defective – see if you can use the VCR to change channel using the VCR remote.
Be sure to vote/rate me if this helped Thanks!

Unusable Signal


Hello Mike:

The issue that you are having is with your small signal board and it needs to be replaced, it sounds like the microprocessor on that board is getting locked up.

HDMI ON ILO 32HD


it sounds like there is a problem with either the output on the PS3 or the input on the circuit board of the TV. I would try a reset on the PS3 first. Also make sure that there are no other video or audio cords plugged into the PS3 because this will cause the PS3 not to send the signal via the HDMI.
