kdl 50w755c remote control problem

[desmo999s]

Had to change battery to remote control to an amplifier Nad d 3020 and this does not work after the remote control of my sony tv. Then I pulled out and I put the batteries of Sony remote control and afterward WORK.

Why?

Hi there

Sorry, im a little confused at your description.  Maybe it was just coincidence that the Sony remote didnt work atterwards?

Cheers

Most-likely oxidisation...   Remote controls draw very little current, and even a new battery can have just enough of a 'film' over the contacts to stop them working. - It's good practice when fitting batteries to give them a little 'spin' with your thumb to make sure both battery and contact are 'scraped' together and make good contact...

The action of removing and refitting a battery is sometimes enough to clean the contacts... Because contact and batter get scraped together in the process.

THERE ARE NO oxidation. Television is new two months. If when power on tv press power on first from nad u3020 then the remote control of Sony do not work.as to block the FREQUENCIES.The same happens if you press first power on from sony Tv then should take out the batteries from Nad remote control.

It would help if you were a little more coherent...  These remote controls work via infra-red light; not radio frequency transmission!  - So quite what you're referring to really isn't at all clear!   - Likewise, and I'm assuming here that English isn't your first language, BATTERIES are these things -  https://en.wikipedia.org/wiki/AA_battery

- Doesn't matter if the batteries are 'new, two minutes'!  - They can be oxidised enough to stop a remote, or any other low-current device from working until you 'wriggle' them a little onto the contacts.

Why are you removing them from the remote controls?

I'm GUESSING your post is really about your NAD amplifier's failure to 'learn' the remote control codes to operate your Sony TV?  - In which case you would be better looking for a NAD forum where people who own that equipment might be better-acquainted with the peculiarities of that particular amplifier.

I had LG TV with the same Nad and i had no problem.I put new batteries today morning and i had the same problem.The batteries have no problems.And repeat.I have all devices on a extension lead.The evening sleeping Ι press OFF button.The morning press ON button. If IMMEDIATELY AFTER press power on button of NAD remote control, the control of SONY TV not working.Must take off batteries of SONY remote control or make restart TV with use SONY game pad PS4.

Frankly Desmo, you are writing in riddles...  

You didn't previously mention extension leads or a PS4; as to listing the remote codes for your amplifier - all of these thngs seem irrelevant anyway.

As far as I can gather, your NAD amplifier's remote is a  'learning' or universal type - it  simply learns the basic remote codes from your Sony remote. The only thing that occurs to me is that you may be trying to program it from a touchpad remote rather than the main remote - but I'm not even sure about that as I thought these were Bluetooth.

However...  You should program your NAD remote control from the TV's MAIN remote control... NOT the touchpad remote if you have one. - The reason for this is that the supplementary touchpad remotes are individually paired to the set; and the results of 'cloning' it are therefore unpredictable. 

Other than that, may I respectfully suggest that you ask a friend with a better command of English to explain your problem. As I'm afraid what you have written so far really doesn't make very much sense.

How can I program my NAD remote control from my TV's MAIN remote control?Can you link me to a guide or something familiar? Also I don't have a a touchpad remote control. Thanks in advance.
