HPS50 charger

Hello !
I have trouble with ps1205rp charger, from my HPS50. Output is 3.67V. I try to change resistor responsible with voltage regulation and the voltage is in range 1.3V to 6V . I can’t read IC code. Can you send me a schematic ?

Sorry for my English

Thanks,
Horia

The charger itself is not servicable.

Thanks for schematic.
I found an resistor with value changed. now is working correctly.
Thank you.
