A friend is fixing my Elmo GS 1200 P COM, they are LED drivers. (led bar meters)
We are always looking for schematics for the microcomputer, unfortunately is defective, no more sound recording is possible.
Thanks for your help

Hello Alessandro,

Have a look there :

https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.vintageshifi.com/repertoire-pdf/pdf/telecharge.php%3Fpdf%3DOnkyo-TA-2055-Service-Manual.pdf&ved=2ahUKEwjut_TT5JXgAh USEBQKHVKmD1kQFjAAegQIARAB&usg=AOvVaw3NHLerIIMJ8Er6nU5kw8u7

You will find p 17/18 a schematic :

Check Q328 block which is how IR2E07 is wired. It is possible this IC needs a little soft to be load.
If no spare available , it is necessary to re-engineer vu Meter Driving with more common IC's like LM3915 or LM3914
