Sony Amplifier Bust

[black66 0]

My Sony Xplod XM-1502SX amplifier has decided to give up working.

The overcurrent light illuminates.

One of the speaker outputs measures short circuit whilst the other measures open circuit.

If I had a diagram I'd have a go myself.

 

Anyone know where will repair it?

Anybody can repair it for me?

 

Anyone tried these people:

Fixmyradio are pretty good actually but check their repair cost against the value of the amp first though, may not be worth it. Could be looking at a large bill if the output trannies have blown.

 

Any warranty left on the amp?

No, no warranty left.

It's had very little use which is the dissapointing thing.

Purchased by a mate who used it for 8 months then he stored it for a year.

I've had maybe three months use out of it since having it off him.

 

I was thinking about it not being worth repairing too.

 

So I pay the £51+VAT and then if it's going to cost more then they will contact me?

The amp is going to be worth no more than £80-£90 anyhow.

I'm asking for advice how to repair my current amplifier at a decent price.

 

Not what I should replace it with :roll:

If there's no warranty then you could always have a play if you're good with a soldering iron? Do you know if the Sony has speaker protection? There might be a fuse inside that needs replacing, or at worst the transistors have blown :( You can parts from RS or Maplins tho....

I may have look inside this afternoon.

It's a 2 channel amp. As one channel output measures open cicuit and one measures closed circuit I may be able to track back along the PCB and measure to see where the difference is occuring.

 

I would imagine the closed circuit channel is the defective one. I'm basing this on the fact that the speaker itself would 'close' the circuit.

The closed circuit must be causing the overcurrent light to illuminate.

 

Cheers for your suggestions Kev.

Yeah sounds like one of the channels has fried. I hope they haven't used one of those "all in one" transistor blocks the size of a matchbox that houses both left and right channels....they're a pain!

 

Hopefully you'll see two banks of lovely trannies in all their glory.....much easier to diagnose and replace. Hopefully just one of them has overheated and shorted to ground or something....
