50pf9631d ambilight has gone out on one side, how do I repair it with out paying philips (or an authorized dealer) outrageous rates, for a problem that has clearly affected MANY Ambilight owners? This is something that CLEARLY should have been covered under an extended warranty along with the power supply issue which I LUCKILY had repaired several days after (I made the call to support before) my warranty expired. In any case, the actual bulb on the right side of the tv no longer produces light when the tv is on, which is the only time it would work of course. The tv it-self works fine as does the left hand side Ambilight. My technical level is moderate and I am not uncomfortable opening up the back of the tv if it is a matter of taking out a bulb and replacing it.
