Question about Rio EX1000 CD Shelf System

1 Answer

Need RIO EX1000 Power Supply Board.

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

    Hello, Guest!

    Thanks for writing! I would love to help you with your problem, but I cannot locate the component that you referenced. There does not appear to be any such "AR51" on the power supply board (mine is Rev 3). In fact, there are no "AR" components at all. Most of the resistors are designated as "RR," and I couldn't find anything with a "51." Can you be more specific as to where it's located?

    Also, if you have the same unit and power supply board, would you be able to provide me with the resistance values (color banding) for RR3 and RR4 (they are what needs to be replaced on my board). Both are located directly behind the two large capacitors, next to the a large transistor heatsink.

    If nothing else, perhaps we can both help each other! Thanks again!

I don't have any solution for your problem BUT you can resolve mine : what color are the rings of the AR51 component (next to the big dissipator)

Repair or Junk my Samsung UN55C6500VF TV?

Hi William,
Not necessary to junk your TV. Damages due to lightning are extensive at times but from what you have mentioned it appears that may be it is only the power supply board which has gone bad and rest of the TV is ok. Replacing power board may restore your TV.
Good Luck.

E321vl no power. could this mean bad logic board?

The downside of a product getting a power surge is it will never be just right. It is not worth the cost to repair it. Consider buying a new TV instead. Suggest a Smart TV.

If your TV dead after the lightning, then your TV doesn't power ON with red light stays on lit you possibly have faulty main board.

If totally no indicator try to replace the fuse on power supply board if busted or blown (it is usually connected directly from power cord.

If the fuse still blown you need to replace the whole power supply board.

please rate!!!

Why won't my Samsung UN40D5005BF come on?

Lightning damage can do a # on LCD TV's. I've seen cases where it took out power supplies and main boards at the same time. I'm not one who likes to use the "shot gun" approach. You would need to get the set professionally diagnosed in my opinion. Where did you get the main board from?? Are you sure it is a working board?

Emerson TV Model #LC401EM2F Fix after lightning?

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.

At least look at the main AC fuse (F1) in the power supply module, and also look to see if any of the MOV's has blown.

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.
