I have a 52" RCA {Regular Rear Projection) TV about 5 yr. old and it loses all audio sound randomly BUT IF you turn it off and unplug the AC power for about 5 min., it may come back on for anywhere from a minute to hours. If you turn it on in the morning it almost routinely cuts off sound at 4 pm for whatever reason??? I tried to flip the rear switch back/forth between internal/external speakers and once it seemed to reset. Any ideas, otherwise the TV is fine. Getting ready to hit the trash, it is soo frustrating. Please give me some assistance. Thanks Kenny
