My box keeps saying boot. When I channel search, no channels appear. How do get channels to watch?

What channel? Do you have a cable box from a provider? If yes, then the HDMI output from the cable box will go to one of the numbered HDMI inputs of the tv. Use your tv remote to select the correct input (source button) and when you find the corresponding numbered HDMI input, your signal should be there. If you are not using a converter box and your signal comes in from your wall to your tv then you must go into the menu settings of the tv and select a channel search. Usually an "automatic search" will do .Click that and allow for all the channels to be scanned. You will be limited to how many channels the tv will allow. If you know the cable signal has channels 1-200 but your tv can only "detect" channels 1-165, then you will be short 35 channels. Only way to to get more is to get a converter box. The only time you should be choosing a channel (3 or 4) to view cable on the tv is if the cable signal is going through a vcr first and then to the tv

HDMI firmware might not been installed. Contact the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box and press "Enter".

DONT USE the remote that came with your TV

use the buttons on the box to change the channel. did the channel change?

usually when someone only has one channel its because they are changing the tv channel not the cable box channel

think of it like this:
the TV is a monitor and should always be on the same channel (3, 4, hdmi, or whatever) its actually the box that tunes and the tv always stays on the same channel.

so if you change the tv channel you are no longer watching the output of the cable box.

USE the remote supplied by your cable provider

HDMI sends video from a source likea bluray player or 'cable box' to tv it will not send signal so you can program channels from it

turn tv to the HDMI input you plugged device into and watch cideo from that source

you will need to connect some type of antenna to be able to program channels on tv

very few tvs need channels programmed these days since most people hook up a cable or sattelite receiver and change channels that way

hope this helps if not give me more speecific details and i can help you more

good luck

Hello


To tune the local channels do the following.

1 Press the MENU key on the remote control to
display the Main menu.

2 Use the CURSOR "UP" or "Down"
keys to highlight
Manual Channel Search. Press ENTER.

3 Use the CURSOR "Up" or "Down"
keys to select Cable,
Air (Antenna), or Digital Add-On.

After the search is complete, the HDTV will exit the
menu system and return to normal TV viewing.

IMPORTANT FACT: This HDTV maintains only one database

of digital channels. Therefore, when you search for

cable channels, the database of antenna digital channels

will be deleted. You will only be able to receive those
ClearQAM channels your cable company provides.

NOTE:"Not available" will appear on the screen

when an option is unavailable.

TUNING MODE UNAVAILABLE MENU OPTION(S)

Hi - I have the same problem. Also in Cornwall LG were not interested in helping because the TV was 3 1/2 years old. There was a possible fix in the end offered via LG at a cost of £180 + vat - a hardware update that might or might not work but I was not going to pay that so I now watch my LG 42 plasma via a £25 digi box from the CO OP. LG must have sold 1000's of these Tv's so when the digital switch starts in the more populated areas of the country I exect many more web postings.

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.

Be sure you have the HDMI cable in the correct slot for the input channel you are trying to connect. Try another input channel like HDMI 2, 3, or 4 depending on how many channels you have. If you have another TV with HDMI, try plugging it in the other one to see if it is a problem with your TV or the PS3.
