Sony know that this home Theatre System have a problem . I post earlier that this system work only for a short period of time and then do not eject disc , do not turn off and flash ` standby ' for ever . this be my second unit , which I get replace within 90 day after purchase , with the same problem . several other have mention they experience the same problem with this system . practically this system become useless once this happen . I take it to a service center of Sears where I buy the system . the technician say Sony have alert they with a ` Service Flash ' with a clear instruction of what part to change when this unit come in for repair . he say the voltage inside the dvd player be not properly regulate and unable to handle the disc and hang up in the middle something like a computer crash . he replace a resistor for my unit . the technician say he have be do that for many of this particular model that keep come in , and that he have not see the repair one back again so far . my system seem to be work well now . it be a obvious problem that Sony know very well . however , we have to pay for the repair . fortunately , I buy service protection for three year by pay $ 60 more when I buy this unit . otherwise , it cost about $ 150 - $ 200 to get the system back to work . I really wonder why should we customer pay for a obvious manufacturing defect . if Sony want to maintain they reputation and integrity , they should recall this unit and replace the part free .
