I do NOT---and have NEVER..subscribed to the "throwaway" mentality. Most of the electronic items I have ARE 'throwaways"--from someone ELSE..which I grabbed and FIXED..to use myself or to pass on to someone else. ALL of my tv sets fit this category. One exception is my COMPUTERS...both my main one and laptop I am using now were purchased NEW.
BTW...the likely reason for the two 5 volt lines to to reduce POWER DRAW. The stby 5 volts is used to keep the processor alive so it can be ready to receive an on command..from the IR or power switch.. The switched line powers other things NOT NEEDED during standby--which would WASTE POWER_-if in the "on" state..
