I'm sorry to hear you haven't had much luck yet, if none of the codes have worked so far, it will be best to contact Sony who can provide you with the correct one. New codes are produced frequently and we don't always have the latest codes available.
If you contact Sony support they can help you locate the correct code for the TV you have.
Let us know how you get on
All the best

"We have tried to make contact many times with Virgin Media customer services and their technical department since 2009. Unfortunately, they do not reply so we are unable to obtain their code set to understand if any of our codes are included in their remote controls. If more information becomes available, we will update the web site accordingly."
Hi. I'm the Managing Director of UMC UK who are the service and tech support company for the Sharp model you mentioned. Unfortunately, after trying to make contact with Virgin tech support for 3 years since 2009 (we finally gave up in 2012) we do not know the codes. In most cases, the codes follow a pattern, for example, if you know a code for a universal remote control is 2106, then you always add 28 to get the sky remote code (therefore the code for a sky remote control is 2134) Maybe Virgin follow a similar pattern but unfortunately, as they are unwilling to reply to any communication (emails, letters, phone calls) we do not know.
Please note your particular model of Sharp uses the very latest RF remote control technology as opposed to the older technology (infrared) used by the Virgin boxes, therefore, even if Virgin were more cooperative and supportive, the Virgin remote still will not operate the Tv.
Most 'brands' of TV's are moving to RF or Bluetooth technology now due to the advantages these can offer over older infrared technology.
Technically there is no reason why the same IR frequencies could not have been used in all models and therefore one code would have covered all. (But that code is not known anyway due to VM being unresponsive) Realistically that didn't happen as there are several suppliers used for remote controls and IR boards who use their own code sets and given the UK market has been less of a priority for Sharp until recently it didn't believe it was a problem for users to switch on the tv and manage volume using the TV remote.
