I checked today, the power electronics has moved to Chrompet, Chennai, they are no more in mount road. I just went there and opposite to the power electronics office, inside a lane corridor, there are 2 shops for AVR repairs, I have given mine there, I will post again about how it got repaired. There is a shop called Vijay Electronics 1st floor, raj complex, the comples for mobile accessories, he is quit rude and chargers beyond limit, he did open the cabin and he said it will cost Rs.5000 for replacing IC, I asked you did not check the IC or open the cabin, how can you say it is gone.. Be careful, alot of cheating guys in mount road, they are not expertise, however I have picked one shop and have given him my AVR, let me check how he is doing.
