..I would assume that you have carefully cleaned the lense and inspected the flexible ribbon cable..try replacing the spindle motor..in our case they are not expensive..good luck Elben

hi there! turn on the hometheater then wait for the no disc display, press the stop botton, do not release until the unit turn off, you will see the initial word on the panel,then try to play your disc

i had the same problem a prot display then it would shut down. turns out i had the sub disconnected(noise complaint from the shaking at my apartment complex) but the speaker wires for the sub connected to the amp or central unit. when i disconnected the sub i left the wires on the floor behind the sub separating the pos. and neg. somehow the wires got moved around and the pos was touching the neg. as soon as i noticed and fixed this problem the system was working fine. my samsung hometheater model is HT-BD1250

Had this same issue with my Samsung HT-X50, it seems these systems have cheap fans. Mine was under warranty but when I contacted samsung they wanted me to pay to ship it to them. **** that, it would of cost me 70 to ship.

What I did was open the unit take the fan and go to a computer store asking for a similar one, I got all this done for about 10 bucks. **** that samsung warranty

Hey guys! Im glad you found my solution on my blog, and posted it here. I hope you ccan fix yours, or get it replaced on warranty. Im happy to help you with anything, the capacitors i think was 4,7 uF, 100volt, not sure.

Found this information for a Samsung unit with the same internal components experiencing the same problems. http://www.fixya.com/support/t194959-display_sound. I know this drove me nuts so hopefully it will help others.

samsung told me the fan is not working and needs replacement or a tune up??? They can repair it for $150.00....totally sucks
