Amiga 500+ No sound only Static

[TurbineX]

Not surprised looking at your pictures sorry. Still, I'm sure you'll get a replacement easy enough.

While your playing silent games tune your pc..etc... into http://amigaradio.info and keep in the mood

Haha. It's funny you should say that. I've been listening to It while working on this Amiga. It's given me the taste so to speak. Thing now would be to order this one http://www.ebay.co.uk/itm/COMMODORE-AMIGA-A500-PLUS-REV-8A-MOTHERBOARD-WITH-2-04-ROM-/170997485295?pt=UK_VintageComputing_RL&hash=item27d03e8eef

Maybe this little lesson has Installed a fresh Amiga fire into me. It's been a few years lol

Anyways. Here is the Burn I was talking about


Damn. That nasty lol

I'm really pleased that your enjoying my MOD stream! Brilliant.

On a sour note, that ebay motherboard has battery damage also - avoid!

Does it need to be a 500+? I ask because I have spare A500 boards that will fit straight in the case. You can Have one for postage costs.

[spirantho]

You can still resurrect that board - you just need to know which links have been broken and install wires there instead.

Of course knowing which lines are dead is the tricky bit, but that's why God invented schematics and multimeters.

Don't need to be a 500+ As long as i can put my extra ram In there. It would be fine Also what kinda price we looking at on postage? Thank you

I'm rubbish when it comes to that kinda thing to be honest. I'm the kinda person who botched a Sega Saturn Bios change

As long as the memory expansion you have is functional, it should work fine in a 500.

Postage? Not sure. I guess the £6.90 mark on the ebay auction would be accurate.

I just need to dig one out and test it first before I say 'yep you can have it'.

Let me know if you want to. (i suggest Private messaging me with that')

Hi!

If you have multimeter, or any voltage measuring device which can scale to 0-12V, please measure voltages on U14 chip (TL084CN) on pins 1 and 7. Shouldn't be much more than 2,5 volts.  Please look at this pinout diagram --->

http://circuits.datasheetdir.com/37/TL084-pinout.jpg

I had 2 channels knocked out of my 500+ mobo, so only could hear whisperlike sound on one loudspeaker. I found out, it had 11volts on pin 1 (Right audio output pin), but only 2.x volts on pin 7 (Left audio output). So you should take a look at that chip also, it's amplifier chip on your Amiga.

These chips are easily obtainable, and cheap so you should be able to replace it if it's at fault.

Good luck.

Hi and thank you for for the reply. I don't have any of those tools but fortunately I have acquired 2 Amigas within the passed couple hours. They wanted Wii games so I swapped lol

HAHAHAHAHAHAHA! The Damn Fools!

That's the best part about Miggies, get a bunch and HAVE FUN!

Hi,

Don't give up just yet, the Amiga 500 is a two sided board, if you have schematics of it, you may be able to determine which runs where ate up and solder some wire over them to complete the circuits again.
If you aren't knowledgeable in this area, I suggest you keep it for parts when you find a new one.

Indeed hehehe. That's what I'm doing

@TurbineX did your facebook deal come off? dying to know what you got

@TurbineX did your facebook deal come off? dying to know what you got

At present I'm working on getting them down here. The guy who I'm doing the deal with Is getting them to the post office in the morning to weigh them so afetr I know what they are going to cost to send. I will get the courier to collect them and get them down to me. Not sure on price but I'm sure it wont be too much but as soon as I know I will let people know

I'm really not that good with that sort of thing smerf.

If you want I can take a look at it for you - it's the postage that's the problem.  Alternatively get a new one, stick the old board / Amiga on EBAY and describe it as is - then someone like me can buy it and repair it =)  
 
I will bet its salvageable - it's a question of looking closely at the PCB to check the damage and use a multimeter to check connectivity against the circuit diagram and what can be seen of what's left of affected traces.

To be honest. Once I get this deal sorted with the other Amigas. You are more than welcome to the old board If you wish as I may end up using the old case for my pc Load It up with Aros or whatever lol
