in india they willmake me go for repair and wont give a replacement i guess\n\n\nI wish you had let us know you are in India.\n\nI have had a strong feeling all along that your problem is that either your house or your AC cord is miss wired.\n\nThe first question is: - Can you be sure that your receiver was made for India and not some other Asian country.?\n\nI say this as India is like the UK. It is 230 to 240 volts with a neutral and live plus sometimes a grounding pin and sometimes not. I ask this as most other countries in Asia have two phase outlets, where there is no neutral and both pins are live but 180 degrees out of phase. So although the cycles and voltages are the same, you can not use devices across those jurisdictions.\n\nReceivers are normally, in the US at least, double insulated with no ground. This is to try and prevent ground loops. So if you had a receiver not designed for a single phase and a neutral supply you would have the problem you are experiencing.\n\nThe next question is: - Did the unit come with a molded power plug, or did the power plug have to be installed on the AC cord? If the latter you need to check that the right and black wires are on the correct pins of the plug.\n\nIn India the live connection is on the right of the AC outlet as you look at it.\n\nNext you need to check that your receptacles and house are wired correctly. In other words make sure the right terminal of your AC plugs has a potential between ground and the left one does not.\n\nAny of the above problems I mention would give you the problem you are complaining about.
