Hi @mohammadgo76406
Did you mean a Yamaha Advantage RX-A2010?
If so here's the [https://elektrotanya.com/yamaha_rx-a2010_rx-v2071.pdf/download.html#dl|service manual] that may help.
Check if the ''Starting Self-Diagnostic Function'' shown on p.30 still works and if it does what it shows.
Also check what is shown, if anything, for the ''P2- Protection history'' on p.68.
Other than that you may have to start checking if all the power supplies from the power board are OK. The power board schematics are on p.143
