I have a Samsung DLP that I just put in a new lamp mdl BP96-00826A. I started the tv up in service mode to reset the lamp hour meter, but accidently hit reset on another feature. Now the tv turns on and I only get sound, you can see the light coming out the back of the tv but no picture and I can not get it back to service mode. I have tried the mute+1+8+2+power and I get the welcome chime and then tv sound.
