What is the remote control code for Sony Bravia TV KDL-37EX503

Try using a cell phone app for Sony.

Remote codes are purely based on the make of the television and it is irrelevant what the remote is. However, I would say that no one these days buys universal remotes. You buy a Facsimile Remote which is an exact copy of the original.

Ok.

The Universal Remote can be used for the basic operations like turning ON/OFF, changing the channels, changing the volume. However, the main features like TV Guide and internal menu settings cannot be accessed using the Universal Remote. To access the all features of the product, it is required to use the Remote supplied with that product only.

I had this same issue, and solved it by putting the TV in "Theater Mode', which can be acheived by hitting the "Theater" button on the remote.

You will need a code in order for the tv functions of you sky remote e.g volume to work.

If you have a remote control was produced after 2002 or there is no sticker

Most SKY+HD Remotes are produced after 2002

I have the sony KDL 46 EX720 and got the code 2751 to work.

1. Press tv on your Sky remote control.

2. Press and hold down select and the red button together until the red light at the top of your Sky remote control flashes twice.

3. Press tv again

Then enter the remote control code using the number keypad. The red light will flash twice if a valid code has been entered.

Sony Code: 0000

4. Point your Sky remote control at your TV and press the Power button. If this turns the off as you'd expect, then the tv should be set, press Select and the remote should work

5. If the TV does not turn off press tv, then press the Power button again, repeat this process until the TV turns off, when the TV turns off press Select.

Do you use a Home Theater receiver along with your televison?  Are other components, such as a DVD player, VCR, Blu-ray player, etc. connected?
If so, it's possible that the Mute function on your remote is muting the sound from your receiver, and not the TV itself.
If that's the case, you'll need to look at the details of the "default" buttons for your activities, and see whether the Mute function is associated with your TV or your receiver.  If it's set for the receiver, you need to change it to be associated with the TV.
