It's the AVC-20 box, only this exact model will work. Unfortunately it's long gone out of production so the only source for it will be on sites or shops that sell second-hand units.

Indicating Lamp: Lights Orange (flashing)
Power Status: Off (Power Saving)
Operating: Display monitor MAIN POWER is ON ans AVC Center power is ON, with no signal input except antenna (no sync. signal).

Remember that the Display Monitor and the AVC Center have their own AC Power; both AC cords must be completely pluggerd in to the AVC Center and the dislay monitor, then plug them in to the AC outlets.

Really I'm thinking that this is one problem to sync or bad plug connections; for details and tips about this subjetc, suggest review the 42HDT20 Operation Guide.

Hope helped with this.

I'd unplug/disconnect the Roku and after 30 seconds try the control button on the back. If you can change the input do so, then plug the Roku back in. Until you use the input button on the back to change input to Roku, you should be able to use the other buttons on the back to control the TV. If this does not work, unplug both the TV and the Roku. Wait maybe a minute, then plug the TV back in and follow the above instructions. Here are other alternatives: Using physical buttons: You can find the physical buttons on the left or right back side of the Hitachi TV. Using these keys, you can change the input, adjust the volume, or turn on Hitachi TV without a remote. Press the Input button located at the back or side of the Hitachi TV.

A little popup that appears in the lower left corner of your Hitachi smart TV screen may be related to one of the TV's settings or capabilities. You can attempt the following actions to get rid of it: 1.Investigate notifications: Smart TVs occasionally show notifications for different events or upgrades. If there are any notifications, look for them and then clear them by following the on-screen directions. 2.Applications and Inputs: Make sure all programmes and inputs are closed. The popup may occasionally be connected to an input source or app, which can be closed to get rid of it. 3.On-Screen Display (OSD) Off: There might be an OSD option in the settings menu on Hitachi TVs.

Look for a software update option in the TV's settings menu. 5.Firmware Reset: You can conduct a factory reset on your TV if the problem persists after you've tried various troubleshooting measures. The default values for all settings will be restored as a result.

Regarding External Devices: 7.The popup may be related to any external devices you have connected to your TV, like a cable box or game console.

Are you getting the various HDMI inputs on the screen but it acts like nothing is connected? We have repaired hundreds of TV's with no HDMI signal over the years and have never had an update correct this issue. There is an IC close to the HDMI input jacks (U501) that decodes the data, that's always been the defective part. You can order the part and change it but you will need advanced soldering skills and the equipment to do it, I'd recommend replacing the main board if you can find one.
