When the issue happens, I hear what sounds like a relay, switching off then on then off, maybe 3 or 4 times in a row, then the TV shuts off. The LED on the front of the TV stays solid RED most of the time this happens. Sometimes though, it flashes the error code 48 (Red blinks 4 times, Yellow blinks 8 times).
I've taken out the Lamp, and it looks ok. The lamp has 5,648 hours on it. Do you think the lamp is starting to go bad and the controller is sensing a short, thereby giving me the error 48 or is there something else I need to replace?
