OK. So I am making some presumptions here. If my presumptions are incorrect, then you should check those first.
(1) WHEN you are testing voltage at R202, the motor switch (S10) must be on. This may involve manually actuating the switch or depressing play.
(2) You have confirmed that S10 is working properly.
(3) You have confirmed that S10 is getting voltage. You can verify by testing (live), with meter on DC volts function, black probe on a known ground, red probe on S10 contacts, one at a time. Without actuation, one contact should read rail voltage, the other should not. Upon actuation, both contacts should read rail voltage.
IF the above presumptions are true, then you most likely have a failure in the motor driver regulator circuit. The two most common items that fail are either the driver transistor, the regulating zener diode, or both. If you don't want to test, then just replace both of them. If you want to verify first, then I'll need (live - switch actuated) voltage measurements of B/C/E of the driver transistor which I believe is Q43 and both pins of D16. Q43 replacement is not critical if exact replacement part is not available. Just make sure to replace it with one with equivalent or higher power dissipation capability, and hopefully similar HFE. Of course if you replace it with a non-exact part, you need to make sure that the pin assignments are connected properly since the pin arrangements B/C/E may not correspond to the new device.
