Re: lost signal & sound

Lso had the exact problem about 2 weeks ago on my L46WD22. Took it to the authorized repair shop and they told me they had others on their shelf for over a month. Since the board has been on back order for a while, my repair shop called and actually got to talk to an engineer at RCA. The problem seems to be a surface mount fuse that RCA said they also could not get. My repair center said that he found a fuse to fit the board, and though it was a higher rated fuse, installed it. TV works fine and it is back in my house, but the repair center is not getting paid for the work they did not fix it!!!

I have a proscan with no sound so I brought a

You hooked up the sound bar to the cable box red & white sockets, right. Now you have the soundbar hooked up to the TV red and white sockets. Did you notice any difference with the labeling on the two sets of sockets? The cable box sockets were labeled "Audio Out", but the TV sockets are labeled "Audio In"

AV signals are directional. Any socket labeled "Out" will give a signal from it for connecting to another device e.g. the connection from the cable box to the soundbar.

Any socket labeled "In" is designed to accept a signal from something else, but it won't give a signal out. So you can't connect the TV's Audio In socket to the soundbar's Audio In socket because both expect a signal from something else and neither supply a signal out.

Check the back of the Proscan TV. Is there a socket labeled Audio Out? If so, use that.

I have recently lost the sound on my 32 inch LCD tv

1.) Check its not muted/ the sound is all the way down
2.) If the TV has seperate speakers make sure they are plugged in to the main unit.
3.) If you are watching tv change the channels, if any channels have sound then the one you were watching has lost signal, try retuning.
4.) If all these have failed your TV may be on the way out :(

My tv comes on and has "unusable signal" floating on it

What is your signal source, OTA or cable? Did lightning or another type of power surge recently hit? Make sure you have the TV on the desired input.

If OTA check your antenna direction and that you have the Channel Setup (from the menu) set to Antenna. Also check if you have the right antenna to get stations in your area. gives the most likely channels and directions. will give more detailed information and more stations. Both sites assume outdoor antennas but the direction information is always good. Look for new construction or big trees that might block the signal. Do you have multiple TVs sharing the same antenna? You might need an amplifier.

If cable, check the Channel setup. Check for someone recently damaging your cable installation (cutting the wires, trying to split the signal to get it for free) Splitting the signal to multiple TVs may also be an issue, get an amplifier of the correct type. Some cable systems may require a bidirectional amplifier.

If you recently had a power surge, see if the TV works with other inputs.
Tuners can be replaced if the TV is worth the labor costs for you.

I hope this helps.

( My household had three tvs and a digital to analog converter that lost their tuners after a nearby lightning strike. We chose to replace the TVs since two were over 15 years old and the third was also out of warranty.)

Sony Bravia 40'' LCD 240Hz TV can't get video signal from DVD

Are you absolutely sure you have it wired up right? Are the Cable RIGHT wires color to color, is the "Correct Input" selected? Remember you do NOT use "Channels" but an AV, AUX, or External.input. Most DVD etc, use AV, IE: Yellow, (Video), Red, (Audio), White (Audio) for the OUT connections. These go color to color at TV end. And uses 3 Cables. The "Other" type of Output/Input is Component Video. This is ALL Video, Red, Blue, Green, these go color to color as well. BUT you MUST also send the Sound, Via the AV, IE: The Red & White, AV, Audio IN/OUT connections, So you in this case would have 5 cables/connections in all.

TV channel shows up behind the picture while watching dvds!

This is the best solution for your problem as a 40 year experience with wires etc. Go to the source of your cable signal connector . Open it and clean the terminals with emery paper , sand the end of the cable shiny clean from corrosion , get a new barrel connectors with gold terminals if possible lengthen the ends of the cable , insert and tighten good, use thick rg-16 or rg 40 cable with good insulation ends crimped professionally with a crimpier or buy ready made , not from dollar store. Get a gold plated professional splitter if you need one or two , it will cost about 15 or more each . Make the cable runs as short as possible, using the thick good cables. If needed get a signal magnifier. From radio shack or the source etc. Connect them good and tight . Ground the splitters . Problem solved , you will get crystal clear channel 2 to 7 including 3 and 4 . Isolate the TV cable from other cables and power wires. Vitally

Philips LCD 17PF8946/37 TV not working

The good news is that the "No Input Signal" message means that your TV is not broken. If you are trying to watch cable, then you have simply turned the TV to the wrong input channel. If your cable comes into the Philips using a coaxial cable wire, use the Philips remote to change the channel to Ch.3 or 4 - whichever channel you normally watch cable on. Make sure the cable box is turned on if you have a cable box. If the cable box connects to the TV using another type of wire, use the Ch+/- on the Philips remote and go through all the AV channels until you find the right one. Good luck! Let me know if you need additional help.

You can try using an rf modulator to convert the coax signal into one that you connect to the tv using RCA jacks. I believe that model has one source on it for AV. Most stores carry these and they are relatively inexpensive.
