Manuals
Notes
Unlike some Orion TVs, all of its functions can be accessed without the remote. The A/V inputs can be selected using the channel up/down buttons, and the menu can be opened by pressing volume up & down at the same time.
This model can be modified for RGB input. The process should be similar to the 19A21, although you will have to verify the correct points to use in the service manual..
Like many Orion made sets from this time, this tv includes an hour counter. To access it you need to hold down 6 on the remote while pressing the volume down button on the tv.
