Not sure why but this morning none of the macros, etc. worked. They visually did what they should but no go.. So, turned it off via the on/off switch on the back. Turned back on and it has been stuck on the screen with

Pronto PHILIPS
PLEASE WAIT

for well over 5 minutes now..

Anyone know how to do a hard reset?

For good measure I would go a step further. Perform a full firmware update on the remote. For details on how to do this see here.

Nothing worked, called Philips (very nice tech support guy I spoke to BTW). He had no clue about a way to do a hard reset. Could not reflash the firmware update since it was stuck and thus the desktop software could not connect to the Pronto. In any event, after about the eleventy-billionth back and forth of the On/Off switch it finally rebooted and all seems good now.

Weird...

Sadly whatever gremlin took ahold of my Pronto Pro have resurfaced and with a vengeance, now impossible via any means to get control except on a rare occasion and when it does it refuses to communicate with the RFX9400. Calling Philips in the morning to find out what is necessary to get a replacement. exactly one month after purchase and kaput...

You never mentioned you had a RFX9400. Are you turning it off and on as well?

Yes, tried that via moving the switches so it would reboot and removing power for a couple minutes as well.

Gave up, called Philips and sent both the TSU9600 and the RFX9400 in for warranty repair/replacement (not sure which is FUBAR).
