I would have thought you could just select a different source from the remote. Can't you do that? Usually press the source button a few times to go through the different options on the screen.Need to select the analogue tv through the antenna or else digital tv through the set top box I guess so you would need to select the right source where the box is connected.. Did you do the initial set up and let it auto tune all the analogue channels when you first plugged it in. I found this in the online manual but the preset button is one of the 3 menu items you can't select so you may not be able to follow this instruction any way.---------------------------------------------------5.Air/Cable selection You can select the signal receiving method according to the following steps:1) Press the MENU button to enter the main menu.2) Press the button to select the itemPRESET, and press the button to enterPRESET menu.3) Press the button to select the item tv source.4) Press the button to change the item among air, catv s, catv h and cath i.6.Channel search------------------------------------------------have you checked if the parental lock is on or if some of the channels are locked out from the initial channel set up screen? Saw someone else make a comment that they got the tv new and it had a vchip blocked when they first got it out of the box and lots of channels were locked off and took him 2 hours to figure out how to unlock it from the menu. Didn't say how he did it unfortunately. This is the manual if you don;t have one already any ways.
Have you checked that your aerial is connected into the set top box & not into the TV? The aerial signal has to go into the set top box & then the box will be connected via your Scart cable into the TV. On the TV you will need to select the Scart input ie. AV1. This should give you the set top box incoming signal, you might then have to tune in the box by following the on screen instructions. Hope this help.
Hello boss, here is d way to make best use of it. step 1.Make sure ur LCD or Plasma HDTV has an HDMI port. Hopfuly u bought 1 with it, if not, you may be stuck using component cables. Not bad, but not he best. Component cables change d digital signal frm the cable box into an analog signal. This conversion allows for signal degradation. U want to keep the digital signal transmitted frm the cable company 2 go directly into ur HDTV. An HDMI cable will provide u wid this capability n with d clearest picture. 2. Make sure ur cable box has an HDMI port. Most cable companies do not offer a cable box with an HDMI port on the initial install. You may need to upgrade by calling your cable company and asking if they have a cable box wid HDMI capability. Ask them 2 send u 1. 3.Purchase an HDMI cable. TIP - The longer d distance between the cable box n d HDTV, the better d quality HDMI cable. This is due to degradation of d digital signal over long distances, wiz could result in a poor quality picture. ne distance over sixteen feet should be compensated 4 by using a heavier gauge HDMI cable. Oh yea, don't get taken by buying the most expensive cables. From what I have read, companies are cashing in on this relatively new technology. I bought my "gold-plated" HDMI cables from an Ebay Store, "eforcity" for about a quarter of the price found at the local electronic store. Connect one end of your HDMI cable into the HDMI (out) port on the back of your cable box and connect the other end to the HDMI (in) port on the back of your HDTV.55 Read the instructions that came with ur new HDMI compatible cable box. These instructions will explain the download process the cable box needs to go through before use and the Setup Wizard that will program the cable box to send the correct picture format to your HDTV. If u did not get instructions, u can get them at the cable box manufacturers website. Scientific Atlanta's website: http://www.scientificatlanta.com/products/consumers/new_cableboxes.ht64. Adjust video, audio, and screen settings to ur liking. The explanation for these settings can be found in ur HDTV's user's manual.75.Push ur "source" button on ur remote control or HDTV n select HDMI. Tune to a Hi-Def channel. Most Hi-Def channels r in the 700 channel range. Check cable company listings 4 d specific channels.
If you are trying to get 'off the air' signals then you must scan for the new digital channels in your reception area (this info should be in your owners manual). If scanning doesn't find any signals, you might have to add a VHF/UHF line amplifier(s) between your antenna and the TV set or improve your outside antenna or the cable leading from it to your set. You might have to resort to subscribing to HD cable or satellite TV.
