my mhl to hdmi has stopped working since an upgrade to 4.4.2

I have a samsung tab 3 and a samsung mhl to hdmi adaptor. I have used this to watch content through my tv for over a year. Three days ago it stopped working. I get a blank screen with 480p on it. I had an android update recently but not sure this is connected as i think it worked the day after the upgrade. Version now is 4.4.2. Please can anyone tell me what to try?
