I have the following problem with my atmega32u2 programmed with FLIP 3.42. I tried different hex files (Hermes 4b and the actual hex from the ps3key website). Resetting and programming gave me some problems at first using win7 64 but these are solved with my old pc using win xp.

So everything seems fine but after plugging the dongle in my ps3, connecting the power cable and pressing Power-On/Reset, I don't get any signal on my Monitor connected via HDMI. The PS3 starts booting and after a few seconds it gets really quiet, just like a standby mode and the screen stays black.
The dongle itself has no LEDs since I ordered a cheap (no Hong Kong) Version from this website: Reusch Elektronik. Other customers are fine with their dongles.
Can anybody help me there please? Should I try another hex file perhaps?
