SOURCE: DTV converter Box and Zenith system 3

Make sure the TV is set to channel 3 if that is what the output channel is set to on your converter box. You can also test the TV by hooking up a good VCR to the TV and play back a good tape on the channel that VCR is set to output on. Now the important thing to remember if the setup is correct is that with Digital signals, you either have it or you don't. If the digital signal is too weak, it will show up as "no signal" and you may have to invest in a good outdoor antenna, rotor and good antenna amplifer to get a viewable picture, especially if the station you are trying to receive is over 50 miles away. Hope this helps, your TV is probably not at fault.

SOURCE: unusable signal prompt on video input

be sure to cycle thru the input selections-- either w/Remote (input button), or channel +/- on the panel. my truflat 26" hd set has side/front/video1 video2 inputs, yours may have more or less. also, be sure you've plugged into an INPUT set, not an OUTPUT set. Does sound work otherwise on this set? If not, maybe interal speakers (menu setting) is set to off/not checked.

And on your PS3--goto the settings menu, sound outputs, make sure you select A/V connector and analog sound. The ps3 cable can become sloppy too, wiggle/check/reseat or try another cabe (usually video is touchy more than the sound though)

If you KNOW you've got the right input selected and the PS3 is setup properly, do you have another device with audio output to test on the TV? a notebook computer, walkman, cd player--anything that has rca outputs for sound--quick swap the cables to the new 'test' device-- if sound is OK with test device, either PS3 setting or cable is bad/wrong. if no sound from test device on TV either the tv is not using proper inputs, or is damaged, or the test device is not properly configured. If you have another input receiving device to test the ps3 output sound, like the LINE INPUT on a notebook computer, or a boombox with Aux inputs, test the PS3 sound output too.

My rca tv has unusable signal onit

Hi, Check the cable connections to and from the TV.
Change the channels to see if there are others that are out.
If you are not using any cable company then you will still need a set top box to unscramble the digital signal. Good luck.

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.

Power went out while tv & Direct TV was on

The garbage on your unused channels are not important, just artifacts from signals not strong enough to produce a picture.
The 'blue screen' on #3 is what many sets use when they sense they are connected (terminated) to 'something' but not receiving any signal.

If sounds a lot like DTV's receiver took a hit.

If you have a second set you can borrow or drag to the receiver, try it first but I don't think it is your problem unless the cable input on it was zapped.

Picture goes out, sound stays on

I am not familar with that particular set, but this is what I would check (assuming you don't have a surround sound system hooked up to it as it would sound like a tuner problem otherwise). If you have external Audio/Video jacks with cables hooked up to the Direct TV box, move the video cable and see if you lose video when it is jiggled. If so, you either have a bad cable or connection/connector. When you say you have to turn the TV off for about 30 minutes, do you leave the directTV box on? If so, then the problem seems to be with the TV. Otherwise, maybe the direct TV box is at fault -- leave the TV on and turn off the cable box for a half hour and try it again. You have a few possibilities here, good luck.
