 I have the same player and faced the same problem. Dont worry it easy to fix. Inside, the layout is powersupply board, and then the big mother board. The problem is in the power supply stage. The main driver IC in the middle of the power suppy angainst large black heatskink after the switching stage, value TOP 249y, part number J903 is the problem, this IC neesd changing with a new one. Make sure the IC stands up correctly aginst the heatsink. and then solder it. It easy to precure and it cost around Rs. 80/-, if the problem exits with new one, that too is defective, try and buy one from abroad, indian local ones tend to be of poor quality. Cheers. |
