The power light flashing means the machine crashed. It probably has nothing to so with the floppy drive. To help you further, can you say whether it's a 500 or a 500+ , or if it comes up with a white or purple screen with no disk inserted. Also, what game(s) made it do this? trust me, it's all relevant.

Hi,

A couple of things first!  You need to count how many times the power light flashes, and is it consistent?  Ie. happening at same point or various random times?  Are you getting a picture at all, you mentioned your remote isnt working?  At this stage it could be (off the top of my head) the PSU, floppy drive (some models have surface mounted caps that fail related to rotation speed), CIA or worst case RAM (not socketted, hard to remove).


Think he means the TV remote ;) also, he stated that it 'loads but not properly' so it seems like the machine kick-up ok. Think we're onto a compatability or dead disk issue.

Yes, i thought he meant he'd not got it working with the TV because the remote isnt working?  Why else mention the remote?  Hopefully its the drive.  He mentioned the game worked previously so it can't be the KS version, logically it's going to be the disk, the drive, loose chips, leaked battery, CIA, or RAM - I would check in that order.  Btw, you can swap the 2 x CIA chips around to see if the behaviour changes - if it doesnt you can rule that out.

One of the most common chips i've seen fail in 500's and 2000's is the CIA, and it normally follows movement of the machine, static, and or removing devices whilst the a500 is on - design fault, something to do with different ground levels.
