Can anybody please guide me how to know the current Firmware version on my philips 42PFL7977 model, and also where can I get the firmware upgrade if available, I have checked the link posted at the start of this thread but it shows nothing for this model ..

Also I need to know whether joint space is available for this model, after keying in the string of numbers I donot see anything coming up as said , the joint space logo would flash , but for me its not happening.

Advises/suggestions highly appreciated .
