How to revive a nearly dead falcon ?

[yungjoon]

My falcon is nearly dead.

I tried everything I could after having read posts and posts on different forums. The only thing I can't do is electronic repair.

Originally it was a CT63 config but I set it to stock config. I get a white screen, no boot with/without disk (floppy, ide, scsi), even with a new nvram.

Is there someone who is able to repair a falcon in this world ?

If not, I am afraid that a CT63 will be on sale, Bye bye cubase audio 060...

Are you coverclocking it ? most people claim 72-75mhz with the rev1 CPU. I never got it stable past 66mhz.

I am guilty of having same problem There are shortkeys you must apply at power on, they are Control or Alternate keys before Atari Logo at power on. Press and hold Control or Alternate before Atari Logo and at good moment, took me a few hours

When you removed the ct63, did you place the jumper back on the bus connector nearest the front of the machine? The jumper location is marked with a white box around the two pins concerned.

Damn! I forgot the jumper...

Thanks DAL !

- I set it and my stock falcon rebooted again !

- I replugged the CT board, 030 mode was ok, but I got a wrong resolution (15KHz, black screen...) on my VGA screen.

- I tried several restarts, switch on/off, reset,... no success

- I believed I let my hand on space bar before switching it on and the CT boot mode appeared again ! YES (explanation?).

Now, I still have some problems:

- crash after TT memory test (need to try other memory modules)

- ACE midi freeze after loading (DSP issue ? How can I test the DSP? I already performed the pre-boot tests and it was ok)

I don't think the falcon is stable. I must do some tests to be sure (nvram status?).

Thanks for all your replies.
