[comp.sys.amiga.tech] Amiga 500 hardware problem.

HELP!
   I need y'all's help.  My Amiga 500 has 'died' and I need some advice
   and suggestions as to the possible cause.
   I have an Amiga 500 w/ 512k.  Two days ago I bought a 2400 baud modem
   and an RS232, 25 pin, m-f cable for it.  After using it for about
   25 minutes, the screen suddenly developed thin vertical blank lines,
   then the pointer disappeared, and finally the middle of the screen
   filled w/ blue static.  I promptly rebooted and was greeted with:
    
    a green screen and the power light's blinking 11 times, pausing, and
    repeating.
     
   I seem to remember reading a yr ago about a similar problem, and if
   memory serves the cause was a mis-seated Fat Agnus chip.  I have 
   therefore tried to reseat it (I've tried removing it completely and
   re-inserting it).  Didn't help. I've tried the drop fix too.
   I finally broke down yesterday and took it to a repair place, and
   after replacing all the major custom chips and checking the roms and
   rams, they still can't find
   the problem.  Their solution is to completely replace the
   motherboard!
    
   Have any of you experienced a similar problem?  Does anyone have
   any advice as to other possible causes?  (I really don't think
   the modem had anything to do with it, but I thought I should be
   complete.)
      Any suggestions would be greatly appreciated.  Pls send responses
      to my id:  hanes@phao.eng.ohio-state.edu
       
   Thanking you in advance,
   Mark Hanes   

   P.S. Does anyone know of any more Amiga repair shops in Columbus OH...
	I know of only one.
