Hello
Three digit universal remote codes for Sharp tV are:
004/ 009/ 079/ 095/ 111/ 112/ 114/ 122/ 123/ 124/ 173
Four digit codes are:
0079 0123 0063 0020 0004 0009 0226 0266 0006 0095 0122
Direct Code Entry

1. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
2. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks, then stays lit.
3. Enter the 4 digit code from the code tables. Note: after a valid code entry, the red indicator turns off. For an invalid code, the red indicator flashes.
4. With your device on, press CHANNEL UP. If the device responds, no further programming is required. Note: If some buttons do not operate your device, try one of the other codes for your brand.

Based on the model number and type of remote control being used you can locate the code numbers for Sharp televisions. If you have tried all of those that came with the remote you can look up additional 3 or 4 digit codes (depends on whether or not the remote utilizes 3 or 4 digit codes) online.

Check the cable box for the manufacturers name and see if that isn't listed in your owners manual.

Try encompassparts.com and see if they have the original remote. The channels you are getting are digital channels. You are going to have to get it back to analog channels.

try making sure tht tha scart or HDMI cable is securly fitted (depending on which one u using) and this suld solve loss of picture or sound

I got a a sharp LC-32D43U and for my motorola cable box i use hte code 31 from jerrold, i take it from the manual and i got it tryin every single code unti i get one that works.
