Hi all,
 Im new to the group and this is my 1st post. I purchased a DX7IIFD and when I received it  I was told the battery had been changed but the synth would not complete the boot sequence. All I get is 88 and then it freezes up with a Red letter P. 
 On the display there was just faded gray squares no text. I verified battery and supply and all caps, even the Quartz crystal. All was good. I then erased the Eprom and wrote the 1.9 bin file to the eprom. Then rebooted.
 

 Now on the right of the Display I get  "attery" I gather that is Battery and on the far left side I get " ~ ! " Yes the battery is good. Also all buttons are still frozen.
 

 Any Ideas?
 

 Best regards to all and thanks for the add.
 Garry
