Hi all,

My TSU7500 seems to have recently developed an issue.

My home button, volume buttons and mute button seem to have stopped functioning correctly.

They beep, they show the symbol on screen to suggest that they are sending commands, but do not trigger my devices to operate. The home button beeps, but no longer returns the remote to the home screen.

If I perform a hard reset to factory settings, the home button works. As soon as I upload my PCF which has been working for years, It stops working. If I use the simulator, the home button returns the screen to the home screen, but this does not happen in reality.

I've tried factory reset, updating firmware, re-learning codes but nothing seems to work. If I create soft buttons using the same IR codes, they work fine... I'm totally bamboozled - any ideas??


Thanks in advance,

Tim
