Did My Solenoid Fry in my RCA VDT-350?

Look in the parts list see if it has anymore info on the solenoid.
Moyer electronics is your best bet for old parts .you will need part number then send
Him an email
.are u staying thee is 17v across it or the power supply is dropping 20 t o 17

Yes, across the solenoid leads on power up I measure a constant 20V. When play is pressed, it drops to 17V. The schematic shows 19.86 supplied to both leads. From there I'm not sure how to read the schematic as there seems to be multiple transistors for different functions (play, pause, etc.). I'm assuming that based on which transistor is triggered, the voltage is supposed to be changed. On one of the leads in the schematic, it seems there is a diode on one.

I really need to study more on how to read schematics. I seeing the diode on one of the leads with 19.86V and it is pointing towards the source, not the solenoid, so I'm assuming no voltage should be getting to the solenoid until play is pushed and one of the transistors gets triggered and applies voltage, or ground? to the second lead on the solenoid.
