My TV says "unusable signal" when I connect it to the wall cable. I don't have cable service, but just want to watch basic channels (my TV doesn't need a converter box). How do I fix it?

You need a cable service to have anything come throught the cable....Recently, all boradcasters went from analog to digital, so at minimum you need a digital receiver box.

I have a apex tv and a dvd/vhs recorder, with a cable from wall only, how do I install


If you wish to record (VHS) off cable :
First connect the co-ax cable from the wall to the input on the DVD/VHS , then connect a second from the output of the DVD/VHS to the input of the TV.
You will need to match the channel (3/4) output and input. There should be a switch on the back of the DVD/VHS.
Tune the TV to channel 3 or 4 to match, To watch DVD/VHS .
Channel selection will be with the DVD/VHS when it is powered on.
TV will tune to channel when the DVD/VHS is off.

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.

CANNOT GET PHILIPS DVDR3305 TO RECORD ON PANASONIC TV.TX-L37D25B WHILE WATCHING ANOTHER CHANNEL?.


What is your source? Since the DVDR3305 has an analog PAL tuner and most TV stations are broadcasting in digital, you probably have some sort of set top box connected to the recorder. If you change the channel on the set top box, you will record the program on the new channel. If you are recording PAL and your TV has a PAL tuner, you should be able to just record one show while watching another with the DVDR3305 daisy-chained to the TV. Just make sure to change the TV channel not the channel on the DVDR3305.

If your TV has a digital tuner, you can split the signal before the set-top box to record one channel and watch another. (Note: basic splitters will cause some extra loss of signal and may reduce a digital signal below the threshold needed to tune in the signal. An amplified splitter can avoid this - when the amplifier is working properly.) Otherwise, you need a second set-top box (or a dual tuner set-top box).

On my set-up with an aerial antenna, I would put the splitter between the wall jack and the electronics. The incoming cable goes to the splitter, then cable 1 goes to the TV. Cable 2 goes to the set-top box. Tune the set-top box to the channel to record and check the settings with the TV set to the DVD source. (DVD set to record on Tuner (and the specific channel of the set-top box output) or front s-video or EXT1 or EXT2.) Then change the TV back to the TV source and change to the channel for the second program.


The manual for the DVDR3305 is available from Philips. The link to the manual is http://download.p4c.philips.com/files/d/dvdr3305_05/dvdr3305_05_dfu_eng.pdf .
I hope this helps.

(I actually use an A/B switch and do not try to watch a second program on the TV connected to the DVD recorder. However, most of my recordings are for time-shifting of programs that air when I can't watch any TV program.)

I have my rca model f36665 hooked up strait from the wall to the tv and I can't get it to find the channels. do I have to have a cable box?


First if cable I presume you have entered the menu and selected cable.

Another possible reason is the tuner/s in this set are bad---hook a DVD or something to one of the rear inputs and see if set works.

If set works that way and tuner turns out to be bad you can with a box with av cable out connections on back just go into a rear input and bypass the tuner--leave set on that input and change channels with the box.

Let me know if you have questions and what you find---usually on this set if no signal---"unusable signal" will appear on screen if no signal.

How can I connect a 5.1 sound system to a sharp


Sharp televisions don't work like you need them to when connecting them to a 5.1 sound system. You can connect them with a fiber optic cable from their digital audio out to the sound system's digital audio in BUT when you turn everything on no sound comes out of the sound system. So you start checking connections and troubleshooting, call Sharp, and maybe even call the sound system manufacturer. You may get a customer service representative knowledgeable enough to explain to you that Sharp televisions were designed without center channel capability. This means that the only use for the digital audio out is to get sound from your sound system when watching tv channels when your Sharp television is connected to your rooftop antenna only or directly to basic digital cable with no cable box or satellite tv receiver. Yes I just stated that you only connect the sound system to the Sharp television when you are watching over the air broadcasts or basic digital cable without a cable box.

People say "but that doesn't make any sense." But it is true. Sometimes you will get lucky and connect a Sharp television to the sound system with the fiber optic cable and get sound out of one of the devices you've connected to the Sharp television with an hdmi cable. You will then be directed by the customer service rep to connect all your devices to the sound system and connect them all to the television as well OR connect all your devices to the sound system with hdmi cables and connect the sound system to the television with one hdmi cable.

Watch tv properly with JVC DVD off


Some philips tv's have a built in aerial amplifier, perhaps if you bought a digital aerial booster it will improve the picture quality.

What is your TV input connection? Are you using Antenna? Cable? Dish?

The Unusable Signal sounds like the TV is not getting a signal. Does your TV have a built in HD Tuner?

If you are using Antenna you might want to try setting up the connections and it should search for quality channels that you get good signal strength. If you are on channel 2 and there is no over the air channel 2 it may say "unusable signal".

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.

Not able to scan stations


I don't understand why you would bother to scan channel when you have directv or dishnetwork???
directv or Dishnetwork required their units in order to watch any channel,which means:
A. Depending on your TV setting,if you use RF connection from your basic directv to the tv,you would have to leave the TV on Ch.3 or Ch.4.to view the rest of the channels,you have to change it from the directv or dishnetwork box. You are NOT able to scan the rest of the channels from the TV,bottom line!!
If you have comcast or your local cable provider,once you have activated,you could use the RF signal coming out from the wall plate straight to the tv and go to TV auto programming,it will auto scan the available channels for you.
Don't waste your time on directv.
If you are thinking about recording from your BASIC directv or dishnetwork box, you would connect SAT. signal from the wall plate to the directv box,then use composite video/audio output and connect straight to your VCR/DVD player under composite video/audio input. Now you could record the viewing channel to the VHS.
Good luck!
