Hhmmm, it sounds like you got a bum unit. It happens from time to time. Contact Intel Customer Support and they will send you a replacement unit.
Sorry, don't mean to be abrasive, but did you read my entire post?
I returned the first CompuStick to newegg. And got a replacement.
That means I tried 2 different ComputeSticks !
Are you are suggesting that they BOTH were bad from the factory?
If that is the case there is definitely a problem with Intel production!
No, I read it completely. Yes, both could be bad (it happens). No, you don't need mSD card installed and no you don't need keyboard or mouse installed (though you should). I presume you set the input for the TV correctly? [just to throw in my own abrasive comment ]
I have used both first-gen and second-gen ICS units - without issue - with a couple of Seiki TVs (in my case, both are SE24FE01 model). I have also used them with adapters and DVI monitors.
Don't shoot the messenger; I don't work for Intel (well, not any more; I'm retired )...

It is sad to see that both Intel® Compute Sticks showed the same behavior, Please as Scott suggested contact our support center to process the replacement.
Please let me know if it happens again.
