Ok, I bought a samsung dlp tv back in october. Model hlt4675s samsung. HAve not had any complaints out of this set whatsoever until recently. About 2 weeks ago until the present when the set is turned on i hear a loud "popping" sound. At first i thought oh no, the bulb is getting ready to fail, but the lamp light on the front of the tv is not lit up to let me know that the lamp is bad. I have had no degradation of picture brightness and the tv works normally. The "popping" sound is almost like a speaker but i have the speaker volume all the way down on the tv since i use my external sound system for everything. Any advise would be greatly appreciated.
