Question about Polaroid FLM-3732 Television

1 Answer

I had an HDTV cable box installed. I used the remote from my TV rather than the one that came with the cable box. The problem: The tv remote will NOT operate the tv. I have a black screen with a 'box' saying No Signal 7-2 KABC-NN. I cannot get rid of this box. The cable company sez I did something with my remote that is not related to the cable box. I have unplugged the tv and cable box..same thing when I turned them on.

Sounds like your on the wrong Input, make sure the cable box is turned on and press the Input button on the remote till you get a picture.

How to control my cable box with the tv control


hello!
refer to your TVs owners manual. You will find codes for common set top boxes there. all the new TV remotes are universal. If you see "cable" or "cbl" button on remote, you will be able to do so. Worst case scenario: you need to buy universal remote or use your cable box's remote to control basic functions on TV. Codes for TVs are included with cable box's remote control. Or, you can call your provider and ask for "Sony Bravia"codes. If you have a satellite box, codes are supplied right inside "setup" menu of the box.
Good luck,
Alex.

I don't now how i recive tv chanels in hd


Your source has to be in HD like a local broadcast TV station currently broadcasting in HD which you get with a VHF/UHF antenna connected to the HDTV. Most primetime TV shows are in HD so using the antenna on the HDTV is all you need. Press MENU on your TV remote and make sure you have ANTENNA set instead of cable to get local TV stations.

You also could use your local cable TV provider. You would need digital cable service and a HD cable box with HDMI or component video cable hookup to the HDTV. HD channels are typically above 100. Call your cable TV provider for more details.

Read your user manual for the LG TV. Ask for help from family, friends, neighbors, local electronics shops.

If the cable from the cable box is attached to the TV via a coax cable, then all you need to change the TV channel to either Channel 3 or Channel 4. You may have accidentally push the CH button on the TV remote. Please post back what you find.

OK the cable box remote is the only one that can change channels in this case. because you are using the tuner in the cable box not the TV.
all you need the TV remote for is to turn the TV on and off and turn the sound up and down. if you used the cable input on the TV then the tv remote would be used to change the channels.

DVI Alert, your HDTV does not support HDCP. what does this mean? Please use YPrPb component connection to watch


Ok so, I was having the same exact problem but I got mine to work.

Make sure you have your HDMI cable is connected from the TV and cable box....

1)Turn off your tv and reboot your cable box (my cable box was rebooted by pushing the following buttons AT THE SAME TIME: "info," "vol ," and "vol-").

2)Once your cable box reboots completely, power it and the TV on...

3)Push your INPUT button on the actual TV REMOTE. Give it a couple of seconds and then use your CABLE BOX REMOTE to begin switching the channels. Your HD channels will be in the 600's if you have the same cable company as I do.

Hope this helps...it worked for me

NOTE: Your COAXIAL should only be plugged in from the cable outlet on the wall to the cable box. Your HDMI cable will be the one to plug FROM the CABLE BOX to the TV

Can't get HD channels selected on tv. Tried auto search with HDTV port connected and the menu selected to HDTV


Hello, the HDTV input is what you would use if you were not using a cable box.
You should connect your cable from the wall to coaxial input on the cable box, and connect an hdmi cable from the hdmi output on the cable box to the hdmi 1 input on your tv and then switch the tv to that input.

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.
