Try a reset via the OSD. Check what the signal source is set up.

SOURCE: Weak or no signal

you would need to know if the tuner is picking up analog signals in the air well( stick a wire a little bit in the tuner connection to see if channels pick up good or use an antenna , if so there should not be a problem with the cable being hooked up to it , if there is a problem even with an antenna then the tuner is bad and will need to be replaced , and the cable could have caused it to go out , but make sure that the tuner is working or not first.

SOURCE: Not recognizing signals

OK...1st of all I want to GREATLY tetraedronic, who wrote to replace the F fuse with the G fuse. I noticed our TV had the exact same thing go wrong. I searched for the item # F1455CT-ND and bought it from www.digikey.com for a whole $2.85 including shipping. It arrived in about 2-3 days. Hubby bought a fine SILVER SOLDER and a $20 solder gun @ HomeDepot. We placed a quilt on the kitchen table, turned the TV on it's face and took off the base & back and them the back panel on the metal casement. About 2 inches behine where the coax plugs in there is a TEENY TINY fuse with an F on it.....we placed the new G fuse right on top of it and with the use of a magnifying glass we barely touched both ends with the solder and reassembled all we'd disassembled. Hooked Coax and power back up and BADDA BOOM....we have sound and the analog channels back. For us, there was NO other option. NO ONE here in SE KS will touch this TV. Oh, and when I say this fuse is small.....well...be prepared....you may inhale it, it is SO dern small. I bet it would take 4 or more of them to cover the head of a match from a matchbook...NO LIE. E-mail me with any questions if ya need. jbs_fanci@yahoo.com

Once again, THANKS A MILLLLLLLION for this fix idea!!

SOURCE: no signal when hooked up with a digital cable box

I had the same problem and had the cable guy out and everything thinking it was my box. I figured it out by myself here is what i did to fix it. I have the vizio 32 inch hooked to an hdmi cable and through the cable box i had the aspect ratio on 1080i and i should have had it on 720p once I switched it I havent had the problem since.

SOURCE: Low volume on LG HDTV

I encountered the same thing using the HDMI interface on my new TWC cable box (Motorola DCX-3200). After a little bit of research, I finally fixed it by changing the digital audio mode in the cable box using this procedure:

1. Be sure the TV is on and connected to the cable box.
2. Using the cable box remote turn power OFF.
3. Immediately press the MENU key on the remote. The USER SETTINGS menu should appear on the TV screen.
4. Select the ADDITIONAL HDMI SETTINGS >>> menu item.
5. The ADDITIONAL HDMI SETTINGS menu will appear.
6. Scroll to the AUDIO OUTPUT item and select this.
7. Change the setting from AUTO to L-PCM.
8. Return to the main page
9. Using the remote, cycle power OFF.
10. When the cable box is turned on again, you should be good to go.

I realize these instructions are specific to the DCX-3200, but there may be a similar setup option available in your cable box as well.

The problem here is that the cable box is by default configured to use Dolby Digital audio, which requires an additional 10dB of headroom to deal with the boosted LFE channel. If the cable operator hasn't taken pains to set the system up correctly (and most haven't, apparently), the digital audio level sent on the HDMI interface will be approximately 11dB down from normal analog line levels on the HDTV channels. Changing to straight linear PCM sets the TV receiver audio level on the HDTV channels to match the levels on the non-HD channels.

The only problem with this fix is that if you intend to feed a Home Theater receiver that uses Dolby Digital processing with the cable box output you will lose the Dolby encoding feature and be forced into straight 2-channel stereo. For a simple installation like mine where I'm just feeding the TV, this fix works fine. If you have a more complex setup that takes advantage of Dolby Digital features (when it's available in program material), you may have to live with the problem.

For a technical reference on why this happens, see http://www.megahz.com/specimages/Dolby/LM100%20Cable%20App%20Note%2011-05.pdf

Hope this is useful.

Here are a few ideas:

  • The No Signal, No Source or No Input message will appear on your television screen when the television is not receiving a signal from your Digital Box. This is often a result of either the Digital Box being powered off, not being properly connected to the TV, or if the TV is set to the wrong input.
  • Press the "TV/VCR" button on your remote control if you are experiencing no picture. This button will allow you to toggle between TV and VCR screens and may solve your display problem.
  • Make sure your cable box is turned on.

      Check the back of your Sharp TV for the HDMI input. These will be long, thin rectangular jacks labeled "HDMI." Most Sharp TVs will include another label on those jacks with an input number ("Input 5," "Input 6" or the like). Remember that number. It will have a bearing when you turn on the TV.

    • 2
      Connect one end of an HDMI cable to the input jack on the Sharp TV and the other end to a compatible component such as an HD DVR from your cable/satellite company or a Blu-Ray disc player. The TV won't broadcast in HD if you can't connect these devices with an HDMI cable (though it will still broadcast in standard definition using RCA cables or S-video cables).

      Turn on the TV and the requisite component (Blu-Ray, DVR).

    • 4
      Press the "Input" button on your remote. A list of signal sources will appear on your screen ("Input 1," Input 2," etc.). Use the cursor to maneuver down to the input number corresponding to the HDMI outlet you just hooked up and press the "Input" button again.

    • 5
      Press the "Menu" button and maneuver the cursor to select "Option." Go to "HDMI Setup" and press "Enter." Move the cursor up or down to the desired item and hit "Enter" again. Then move the cursor from side-to-side to select the proper setting. Hit "Enable" to allow the Sharp TV to automatically recognize the HDMI signal and "Digital" to get the proper audio signal from the HDMI cable. Then hit "Enter" again.

    • 6
      Exit the menu and watch TV as normal.

There are two ways you may do this. First, if you have a cable box then all you have to do is hook up your cable box to any of the input and go to that input on your TV and it should come up. Second, if you do not have a cable box, hook up the cable coax to your coax on the TV. On your TV, hit the menu button, then go to TV selection, then scroll down to tuner mode and select cable, then auto scan. once scan is complete, your cable is ready to watch.

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.

Unable to record one tv channel while watching another tv channel


You CAN record one channel and watch another with satellite service, but it would require two separate DBS receivers. The issue is that all satellite broadcasting is encrypted until it hits the receiver, which decodes it and transmits it outward toward your other AV devices. If it weren't for the receiver, connecting the coax cable to your other devices and trying to tune channels with them would yield no signal and possibly much frustration. You would need to split the signal into each receiver and have one connected to the television via one input and the other to the recorder then to the TV via another input.

With cable, you can split the signal without having to have two boxes - this way the QAM tuner in the cable box is still capable of tuning channels while the recorder can tuner basic cable channels for recording separately. You can also have the cable box connected to the recorder via composite so that you can record premium stations on a DVD recorder input mode anytime you like - but you would have to be watching that channel at the same time unless the DVD recorder had a pass-through RF signal (rather than a composite clone) - meaning you could also use coaxial to your television from the recorder and tune channels separately on your television while the recorder is recording one channel.

A lot of what-ifs there, but it is all quite possible.

Magnavox MWR-20V6 DVD/VCR recorder fails to record one time but not the next This problem just recently started as the unit was functioning perfectly up to now. And I've kept the unit in excellent condition and free of any dust. What's happening is this. When the timer is set to record a program, the unit will turn on and begin to record. But after about 9-10 seconds of recording, it will fail and you'll see an error message saying you cannot record on this disk. FYI, this happens too when not using the timer and just pressing record. And in both cases, it's been hit or miss, so one time it successfully records no problem and the next time no. So you don't know when and if it's going to happen, which is really frustrating! What's even weirder is that once it failed, you can wait a few seconds and try recording again with possible success. So if it failed at first, it may work the next time, but who knows if it'll work after this. And even if it does work the next time, after that, it's again hit or miss. This recording problem happens even when dubbing. So it doesn't matter if you're copying from VHS to DVD, using the time, or just hitting DVD record, the same recording error happens. And as I said above, it may work the next time but who knows? And even if it worked then, anytime after that is also very hit or miss. Nobody else touches the unit and it's never been moved or banged. So again, I've kept it in very good shape and working order. No problems whatsoever on the VCR side. And I most often use DVD-R discs rather than RWs, but even with RWs, the same problem can happen. Lastly, finalizing has also become more hit or miss now when it used to be very consistent. So I don't even know when or if it'll be successful in finalizing a discs. Most times, it does work, but a couple of times, it hasn't. Lastly, a weird thing with discs that failed to finalize is this. A few of them were finally able to be successfully finalized after just sitting around for about a month of not being able to be finalized. So for whatever reason, a few of those discs that wouldn't repeatedly finalize suddenly worked. The rest of those that were not successful still cannot be finalized. And I've kept all these discs in plastic sleeves or in a disc case.
