I have Sony VAIO PCV-RZ-40CG system with Sony's PCVA IR6U IR Blaster. Since yesterday, one port of this 2 port blaster has stopped working. For some reason, only one port is sending IR commands to the STB. I have 2 STBs with 2 IR bugs. One port of the blaster seems to have stopped working. I tried switing the bugs (to diff ports on the blaster) and I have confirmed that STB connected to defective port, is not able to change channels any more. I don't see LEDs lighting up when I change channels on IR bug connected to defective port.

I have tried re-calibrating the STB and setting up TV signal again. When its time to calibrate STB connected to defective port, the IR blaster simply does not recognize the STB remote at all.

Two questions.

1) How to I fix it?

2) Where do I buy a new IR blaster kit? I tried Best Buy, Fry's today and they have no idea what it means and/or where to find one.

Thanks in advance for any help I can get.
