    Thanks for taking the time to respond. My HD is coonected to a digital cable box. As for analogue, it connected to the same cable box. In the past, this has not been a problem.

    What is the ration setting? How do I change this on my TV? How do I check the video settings? Again, thanks so much.

    I have a similar problem. When I switch to analog (OTA), I can change the screen format (16:9, cinerama, 4:3) but when I switch to Digital, I cannot access the format menu and stays in 4:3. Only HD broadcasts appear in 16:9 and non-HD broadcasts appear in 4:3. There are only a few channels where I can change to 16:9 but I have to hit the "Format" button quickly after I change a channel.


     Does this sound like hardware failure?

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.

    There should be a button on your TV remote for "picture mode" or "aspect ratio" or something like that. Basically the aspect ratio is the ratio of the height of the picture to the width. Widescreen/HD pictures are 16:9 aspect ratio, while "standard" screen and TV is 4:3 ratio. There are also other settings on your HD TV, such as zoom, and possibly some others. 16:9 will reveal black bands at the top and bottom of the picture on a widescreen movie or program, while "standard" picture will fill the entire screen, but is cropped in order to remove the black bands. The best thing is to leave the aspect ratio setting at 16:9 in order to get the best picture. Feature films are shot in 16:9 aspect ratio, so if you view these films in standard ratio of 4:3, the picture will be cropped, which means you will be missing things in the picture. It is possible that someone changed or "zoomed" your picture because they didn't like the black bands. Note that standard non-HD television programming is shot in 4:3 and will therefore have black bands at the SIDES of a widescreen HD TV if set to 16:9. This causes some people to change the setting of the TV, but as i said, I recommend against it.



    Look for this setting on your TV and make sure it is set to 16:9. How do you have the cable box attached to your TV aside from the coax? Do you have HDMI, S-Video, component video, or what?

How to hook up to hd tv


Use the highest resolution connection your HD TV will allow. This will usually DR570's HDMI connector. Most all digital video devices have one or more. The DR570 has an HDMI OUT. Connect it to any HDMI IN connector on your TV. You will then need to set the TV's Input selection to the Input Number you connected the DR570 to. See your TV Remote or Manual.

The DR570 has three types of output connection options, in order of quality; HDMI, Component(Red/Blu/Grn RCA jacks), S-Video (circular connector), and composite (Red/Wht/Yel, where Yel is video and Red/Wht are left/right stereo audio). Red/Wht RCA Audio jack connections are required to be made on all Output types excepting HDMI.

Note, to get your Digital channels, you will need to toggle the DR570's DTV/TV button. DTV is Digital TV channels. TV is analog channels, the DR570 found on your Cable or Antenna RF input coax, after you have done the Setup/General/Channels/Scan (extended). Scan only finds analog channels. Extended Scan scans for both Analog and Digital channels found active on your Cable/Antenna RF connection.

Note also, the DR570 is not technically and HD receiver. The term High Defintion (HD) is reserved to mean 1080i or p resolution, the highest available. The DR570 is an Extended Definition (ED) 720i or p receiver. It up-converts its ED to fit an a 16:9 HD TV screen. You will hardly notice the difference on your TV, but it is the difference between watching a DVD Movie on a standard DVD player, like this one, as opposed to a full HD player like a Blue Ray.

With my Sony Bravia 46" xbr the screen keeps cutting out. I'm usig hdmi cables and can't find a reason why te tv keeps cutting out. The sound still remains but picture doesn't. Not even out technician can...


Usually this happens to my set when I am in HD cable channel mode after being on a non-digital ANALOG channel.

I basically reset the TV by changing to a DIGITAL cable channel -- stay on that channel for ten-twenty seconds -- then I switch back DIRECTLY to a HD channel (key in channel number directly on remote).

TV works fine -- seems to be a glitch when the TV changes modes from Analog to HD

I can get a picture , but no sound on the TV . What am I doing wrong?


Many RCA TV sound problems are caused by SAP function being activated by TV station equipment that converts Analog TV signals to HD signals. Accidental pressing of the wrong buttons on your remote can also cause this problem.

The incorrect conversions causes the Audio settings to be changed from Stereo to SAP by the received signal.

Solution is to go to Audio set-up in customer menu and change settings from SAP to Stereo. If you find that settings are wrong, change them to "Stereo". Do channel scan if you are using the TV tuner/remote to select channels. Turn off the TV and unplug for 60 seconds. Check the settings again and reset if required.

This problem may re-occur when you select the VHF channel, satellite channel or cable box channel that is causing the problem. It is not a TV fault that can be repaired. The problem is caused by the incorrect incoming signal.

SAP is Second Audio Program, used for second language transmissions.

Second cause may be that the speakers have been turned off in the audio set-up menu.

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.

Am i getting hdtv with just cable feed?


Depending on your cable provider, some of the HD channels may be present. If so, these are ususally located in the upper channel numbers. It sounds like you are receiving some of the HD lineup. A cable box will probably allow you to view more HD channels including the premium HD channels if you subscribe to them. You should not be noticing a delay with the HD channels only. If this is what you are experiencing without a cable box, then it would be an issue with the HD tuner built into your TV set. LG customer service can let you know if there are any software updates available for yourmodel that can resolve this. Additionally, if you are getting your sound from an Home Theater system then you will notice an echo if using the TV's built in speakers at the same time. This is sometimes mistaken as an audio delay. If you are using a home theater system, be sure to disable the speakers that are built into your system.

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.
