Sony DVP-S550D DVD Player
Sony ...
I purchased the Sony DVP-S560 which is VERY similar to this model.  Just after having the machine one year, which just happens to be the extent of the warranty it began having problems.  It would sporatically give us a C13 or NO DISC message.  Other times it played fine.  At first we thought it was the disks we rented but the problem got more and more common.  We cleaned disks.  It even started doing this with new disk straight out of the package.  I tried contacting Sony online.  They made me jump through a bunch of hoops, things to try.  None of it worked.  I called them.  After going through the thousand voice menus I finally got a real person.  He told me to take it to a repair place and see if it needed cleaned.  So I did.  I paid for a ($$$) estimate only to find out it didn't need cleaned but needed a new part which would cost me nearly ($$$) with labor.    I can buy a brand new, non-Sony, player for a little more than that and it will play MP3's, CD-R/RW, DVD-R/RW, all of which my Sony never could do.<br />I called Sony to see if they would make this right.  I sought out the Sony name believing it to be the best available and thought maybe they would like to keep up this reputation.  But nooo.  My year was up, they had my money and they didn't care.  And from what I see on Amazon there are several other people who have had this same problem.  We have friends who had the exact same problem with their Sony DVD player as well....<br />Sorry but if you don't want to waste your money don't buy Sony.
