I own a Sony India Music System, Model No MHC RV 660D, Serial No. 335H358 for the last 3 years. Last week the DVD Tray failed to open up and the system kept going to stand by. I visited the service centre in Vashi, Navi Mumbai namely, SRI SAI ELECTRONICS, Shop No FI-11, Sector 5, Vashi, Navi Mumbai on 06th Jan 2008 (Sunday). They promised to give an estimate by 08th Jan 2008. I have still not heard from them and I'm being asked to call...
