Atari 800XL blown from bad SIO device

Recommended Posts

When I turn on my machine now, I get a "bizzzz" sound about once every 3 seconds, and I assume, a blue screen (I say assume because the no-signal screen is blue on my TV as well)

 

Other than blown capacitors, does anyone have suggestions on troubleshooting?

Those words could mean anything... I don't know what a "bizzzz" sound is. It could be a form of NAK, but what is NAKing at boot?

Do you have SIO devices connected?

 

The normal sound with no bootable devices is closer to a fart type of sound, not a "bizzzz".

 

Can you post a video (with audio, of course) of this?

 

That would be the most helpful way for us to begin to solve this.

make sure your power supply is putting out the proper 5 volts before proceeding and that the television/monitor works with other devices connected the same way ie composite or rf.... before proceeding... we don't wanna cook anything more than what might have been already... then only connect the powered up Atari to that display with nothing else connected...

 

as for what might have blown.... feel for hot chips... what sio device was bad and in what way?

With no peripherals attached, the startup SIO sound shouldn't last more than a few seconds, and not repeat once finished.

If the TV is showing no signal then I suspect it's a bit of a deeper problem.
