If you see any messages particular ones for a phone call they are not from me but the site, I do not use the phone call facility myself only this texting method which I consider the best way, if however you want to use the phone call option this will go to a board for another tech to take up, if a tech considers this viable by phone he will ring you, otherwise if you do not want it please ignore it thanks.

Would it be possible to get me the model number please found on the back of the set OR theowners manual if you have it?

Yes this model tends to suffer from backlight problems, unfortunately this tends to be the backlights themselves <<click

It can be fixed but its awkward

I am sorry its nothing easier, outside of this the powerboard that supplies the LED s could be bad and replacing may cure most of the time with this model its backlight issues
