You should call for warranty service. If the set is very new try to get it exchanged.
There are some very heavy duty power supplies and many high power matrix drivers used in Plasma sets.
The description sounds like the noises are very loud. It is normal with any of these TV sets, if you put your ear right up to the back of the set at the vent holes you will hear some noises. These would be some acoustic harmonics from the power supplies and related circuits.
I am wondering if it is possible that there is something that is becoming less stable. If the set is working very well without any failure, so-far this is a very good sign. Before it gets to be a problem, I would have this checked.
On many models of these sets, they use fans for cooling specific areas. A bad fan can cause noise.

hello, you have a either your su, sd or sc boards fualty and it is a driver sos1 thats what the manual reads the best thing to do if your not electronically inclined or able to fix it is to get a service manual and make sure it is for your specific model and size you will find what the 7 blink codes mean, on my side i have a 42 in pana the service manual for this set and your is similar so since it is not the same model i cant tell you exactly what the truoble is but your best bet is to find a service manual find the 7 blink fualt then without getting ripped off you will know what the service man needs to do if you dont know or cant replace the parts yourself that is besides having to download firmware from your computer to a sd card and update your set but you need to solve the blinking code first it may solve the entire issue. the tv should come on when you resolve the blink codes or replace the fualty board or boards
