The power supply board (AH41-00411A) on a RIO EX1000 that I've acquired is dead (lightning). I repaired it the first time, but then another power surge did even more damage (the previous owner had disabled the fast-acting fuse circuit which I did not have a chance to replace). Does anyone know where I can find a replacement power supply board? New or used would be fine. Heck, even a schematic would help! It's a pretty good music player so I hate to just trash it. Thanks in advance. Bob

if you suspect lightning or a power surge that caused the problem, if it were lightning could have effected the power supply board, or if it was lightning it could have went in on the cable or antenna connection. to narrow down the problem, check the fuse on the power supply board, if that is ok then with a volt meter check and see if there is 5V volts going to the signal board, that is the board with the antenna connection, one of the plugs that go to the board probably has writing next to the wires in the plug, if no 5V probably the power supply board bad, I almost forgot, when you take the back off look for burnt parts. if you have the 5V going to the signal board now the problem could be signal board or power supply.
Lightning damage on LCD TV's can be a doozie. You really need to get it checked out by a qualified technician. I've repaired several TV's hit by lightning, most of the time the damage was limited to the power supply board. However, it is possible that multiple boards were damaged. If multiple boards were damaged, it's not worth repairing the set.
power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
Yes,it repairable.The tv have power at all like the LED power light indication flashes?Yes,tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.No power LED light indication all.The power supply board is dead and also the Tuner signal board is dead.Must replaced both boards.

This could be bad.. You want to check the fuse in the power supply. If you are lucky that is all that is bad. If the lightning got thought the fuse you could have real problems. You would have to replace at least two boards, one being the power supply board and the other could be the signal board or digital board. Sometimes they unitize the signal and digital boards as one board. Lightning can do strange things. sometimes it will just take out a diode and fuse Sometimes it can trash a set making it cost prohibitive to repair.. Good luck.
