I cant tune in my tv its a sharp dv5103h abd i have lost the manual

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.

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.
