Ok, I'll check the threads. I had read some already. Not seeing the schematics on the R2200B I wasn't sure of the changes. I can see that the A model didn't have heatsink fins at the rear of the monitor.

Anyone know where I can purchase or download a service manual for the R2200B or at least the power supply for this model. I have the R2200A service manual but haven't found the B model.

Thanks Ron
