Loud Beep noise on digital cable channels that goes away for HD channels

On my 52inch RCA when I turn to regular analog cable channels there is a somewhat subtle but annoying beep sound that persists, but does not sound when switched to HD. I have it hooked up to a audio theatre and the only things that make the beep noise stop are:

turning off the TV or switching to a HD channel.

    Will that work even if when I disconnect the cable completely i still hear the sound? I just don't want to waste a trip bringing the box in.

Hi,

Could you pls try to discern if it is a beep or a chirp sound. A remote possibility is that the horizontal circuitry is playing catchup with the difference in the frequency when switching from analog to HD or vice-versa and what you are hearing is the PSU chopper or the HOT/FBT. This might be indicative of a component about to fail. This would of course require opening the unit for a look & see and a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

Hello Spizatz,

Check that you are connectign the cables to the correct ports. If you are not sure where to connect them, just change the conenctions untill you find the correct connection or the part causng the problem.

For example, make sure the red end of teh cable is plugged into the red port and so on for the white or other colors.

Good luck and anything else you need let me know,
Dahaka

Check that there is no device near to the digital cable that can cause interference.

Try moving the cable.

Try a replacement digital cable, possibly a well shielded one.

If that does not work the cable receiver box may be faulty and that is the reason for the noise.

I have a RCA D52W20 rear projection HDTV. This TV was purchased in2005. I cancelled my cable and I just hooked up a digital antenna but the TV isn't finding any channels. What do I need to do? I was...


HDTV indicates the number of lines that are shown by the TV. (HD means that at least 720 lines can be displayed in a given picture.) To receive OTA signals, you need an ATSC tuner (digital) of sufficient power (with a clear path to the transmitter) these days. The RCA D52W20 was released in 2002 and only has an NTSC (analog tuner). You will need a digital-to-analog converter to receive OTA TV (unless any low power analog stations remain in your area).

Please note that the basic digital-to-analog converters that were available with the government coupon back in 2009 were SD (480i lines of pixels used) units. HD d-t-a converters exist but are more expensive.

I hope this helps.

(the phrase "digital antenna" is meaningless; check with tvfool.com or antennaweb.org for the direction of local transmitters. TVfool.com will give more information on the type of antenna (indoor, outdoor, amplifier) that you will need to receive channels in your area. Antennaweb assumes an external antenna but is very conservative in the stations that it will indicate that you can receive. Antennas are given a color rating based on how far away the transmitter can be to get a watchable signal. Since digital signals are either enough for the tuner to interpret or you get a "no signal" message, you often need a stronger signal than was needed to receive a watchable analog channel.)

Why will my ps3 not workwhen conected via multi-av cable to the RCA jacks?it does work conected to a hd tv via hdmi


When you use an HDMI cable with your PS3, the system is outputting the signal in a digital format. You need to tell it to switch back to displaying in an analog format to use the RCA jacks, otherwise it won't work. To do this, turn off your PS3. Then, once it's off, press and hold down the power button on the system. After a few seconds, it will beep and reset the output signal back to analog. Just make sure only your RCA cables are plugged in when you do this. Hope this helps!

My 32" Vizio when not on a HD channel has a


could possibly be a Line noise issue from your cable provider, if it's an analog signal. I would try another room in the house to see if your problem goes away. If not, it may be something your cable company may have to look into. This may also be associated with intermittent connectivity if you have cable internet as well.

Sound went out, all I get is white noise that you cannot mute. Happened when I changed from high def to regular channel. Even with everything unhooked still just white noise.


Analog regular channel TV was turned off mid 2009. You need a digital channel convertor box to receive the new digital channels... The analog ones went bye, bye in the USA. Without the box you will just get noise.

Looking for hd channel


To get an hd picture you have to use a digital input and this cannot be done by simply turning it to a channel. You need to hook up your HD receiver (box) to your tv using either an HDMI or a Component which will be a cable that looks similar to an rca but there are three of them and the colors are bed blue and green. If there is a red, blue and green on the back of the cable box and the tv hook them together with a component cable and then find the input on your tv that correlates to the compnent connections and then even after all of this you need to be tuned into a channel that is offered in high definition and if you have cable like I do the high definition channel will be a seperate channel from the regular one. Comcast in my area puts the HD's from channels 400-500. For example my espn HD is channel 403 but just regular espn non HD is on channel 27 in my area.

No digital channels


This TV is not able to understand digital channels because its tuner is not able to find that band, it works only in analog channels. To be able to get HD channels is needed a decoder box that has digital tuner build in. for a tv to understand HD Channels with analog tuner is to us to try to speak at the same time different languages.

Get closed captions on some channels, but not all, even though it is CC


RCA have choices for different methods of CC in user CC menu. Labelled T1, T2, etc. . Different selections are for different types of close caption. Tune to a signal (on your other TV) that has closed caption working.

Tune your RCA to the same signal. Change the T1,T2, etc settings until the closed caption for your signal appears.

If this doesn't work, try connecting analog video or VHF channel 3 (or other specified channel) to the TV. check CC. When TV stations, sat channels, sat receivers, cable boxes etc, convert analog video signals to HD, problems can result. Some equipment causes RCA TVs to do unexpected things with sound and closed caption.

If you use RF or video output, old analog video may look better on CH3 or video than on HD input and the CC will work more consistently. Watch HD signals on HD input, Analog signals on Video in or through the TV tuner . Many HD channels and programs are converted analog video and look poor on TV HD inputs.

RCA D56W20 picture problems


More information is required to properly troubleshoot this problem. How is your television connected when you are watching HD? Do you have HDMI for this, do you have a satellite or digital cable box? For analogue are you using regular coax antenna (cable TV), or are you going through a cable or satellite box?
This could be related to the aspect ration setting. perhaps you ahve changed your aspect ratio from 16:9 to 4:3 or some other setting. If you are connected via HDMI, then the digital signal may be "normalizing" your picture during HD, but reverting back to the other setting.

Check you video settings very carefully. HD televisions are very difficult to tweak properly.

No analog stations on my hdtv 37 inch, have no digal box just regular cable, regular cable works on normal tv


Try an antenna if you want to get analog over the air. I have a feeling that with the way the standards are changing, you will only be able to get digital channels. After February, the analog channels won't be around.

If you are using cable tv you need an HDTV box to get high def.
