Question about Sony BDP-BX1 Blu-Ray Player
I assume you tried the software update after the unit failed. If it quit working because of the firmware update, you may have received a corrupted file. In that case, try downloading a new copy on a different computer or to different media, and repeat the update.
If (assuming hardware problems and not bad firmware) it cannot play any optical disk, not even audio or photo CDs, I would suspect the laser in the optical drive has gone bad. Replacement is not a lot of work, but the part is probably about $50. I think it's likely this is the same part used in the Sony Playstation 3, which had some problems with lasers dying too soon when it first came out.
Here's a way to check: first, insert a DVD in the player. Unplug it and remove the top cover. Caution: do not tip the player with the DVD inside. CAUTION. Directly viewing the laser can cause severe damage to your vision. DO NOT put your face over the DVD drive - ever - while it is plugged in. Observe it from the front, a little off to one side. Before plugging in, check the ceiling overhead and make sure there are no mirror-finish or glassy reflecting objects above the player. The DVD must be in first for safety reasons; it covers the laser. The rest is additional precaution.
Now, plug in and turn on the player. In normal operation, the laser comes on, and the lens moves up and down to focus on the disk. You may see a blue glow in the center of the disk (especially in a dark room). If the laser is working and the laser/lens assembly is able to obtain a focus, the disk will start spinning. If the disk does not spin, the laser/lens assembly is the first suspect. It is also possible that the spindle motor drive is bad, but given the history of PS3 Blu-Ray drives...
If there is no movement of the lens assembly, check the power supply. If it is good, there is (by elimination) another problem with the lens assembly (controller problems, to the best of my knowledge, are rare). Because it has very tight assembly tolerances, the lens assembly is usually replaced as a unit rather than repaired in the field.
