It worked well on My Philips for 10 minutes , started Netflix and 2 sec into the movie it says "no hdpc ,wrong HDMi cable" now the ATV is dead an the led on the front go dark when i choose the HDMI input on the TV, what has happend with the latest update from Apple??? Is the ATV just made to work with à specific brand of tv?? Starting to be tired of the behaviur from Apple products.
I assume it's a straight HDMI connection. Have you tried connecting to iTunes (via micro usb) and doing a restore? If that doesn't work it may be hardware related, in which case you should take the unit in.
