Sharp Tv, can't tune in channels

Hi Jim, your nearly there, all you need to do is go into the tv menu and move from DTV to the old type channel numbers and then find the bit where you can manually tune the tv to channel 68.
Have a sky menu picture running and you will see it come in.

you must have an issue with the cable box in that room

It sounds like you need to do a complete installation as if TV were new.
This is done from installation menu

The Tv is working fine, from the description it is that one channel not coming in, the blue screen indicates no signal. It could be that the signal in that room is a little weaker and just going below the thresh hold to allow it to come through. It is possible the station might have been off the air, try another auto tune.

Good day!!

Example Situation:

If you can get the first thirteen channels, then that proves there are no broken wires or damaged equipment between PVN and your room. Your cable - all 67 channels - has already been activated before you even move into your room. So, if you are only getting channels 2-13, you definitely have a programming problem with your television. We understand that your TV probably worked great last year or at home, but you have to set it up from square one when you move in to Penn again. Many times when you unplug a cable-ready TV, the memory settings are lost, and you have to start over. Therefore, you will need to program your set from the beginning.

If that situation happened to your TV please re-program your set.

Here is a link on how to re-program your Set.Just click the link bellow:

Dear customer,
Sharp TVs often require you to press the TV Tuning preset key which is a yellow function key.        
   Setting Up Your Sharp TV
Turn on your TV.

1. On your Tune In remote, press TV and release.
2. Press and hold Set until the green light on Tune In blinks once, pauses and then blinks twice. Now release the Set key.
3. Enter the first three-digit TV code for your Sharp from the list which follows:
   093, 165, 039
   These codes are listed in order of popularity, and the green light will blink twice if you perform this procedure correctly.
4. Aim Tune In at your TV and press Power. Your TV should turn off. If it does not, repeat steps 2-5, trying each code listed in step 4 until you find the one that operates your TV.

Now Test Your TVWhy test? Many times more than one code appears to work. Testing is desirable to be sure you have the correct code for your TV or the other devices you are setting up.

1. Press the Power key to turn on the TV, then press mute, channel scan ("CH") and volume ("VOL") keys. Tune channels 7 and 11 by entering the number followed by the Enter key.
2. If your TV does not pass the test, return to Step 2 at the top of this page. Enter the next three-digit code and repeat the process.

Sounds like the signal is probably too strong. The TV is not the problem.

Probably the best way is to contact SHARP directly. The owner's manual can be downloaded from SHARP's homepage for free.
