T V in standby mode (orange ON). Hard to turn by pressing button or using remote.

Try following the steps below.
Step 1
Press the power button once. If the TV does not turn on, observe the LED indicator, usually located on the TV's lower front panel. If the LED indicator turned off after you pressed the power button once, it is in standby mode. Press the power button once again to exit standby and turn on the TV.

Step 2
Observe the Standby light if the remote control will not work. If the Standby light stays on, the television is in Standby mode. Press the power button on the television, then try to use the remote.

Step 3
Turn the Energy Saving Switch off, then press the power button. The Energy Saving Switch is located on the rear or side panel on most Sony model TVs. Refer to your TV user manual for the exact location of the switch.

Looking at the user guide it appears that the amp has a standby mode.

See not below on turning standby on. Question can you see the standby light flashing.

I would also suggest using function on the amp to remove any possible issues with the remote.

One would expect the system to return to normal operation by pressing the power button again. If not what do you see on the display.

Note:
Press 1 to turn on the receiver.You can also turn on the receiver using 1 on the remote control. When you turn off the receiver, press 1 again. "STANDBY" flashes on the display panel. Do not disconnect the AC power cord (mains lead) while "STANDBY" is flashing. This may cause a malfunction.

I don't have service mode specifications but I do have a Samsung and looked around for how to get it in service mode some time ago because the HDMI cables somehow disconnected themselves a lot. Thought it was an electronic problem but it turned out to be a parenting problem instead SO I have never used this information and can not vouch for it. I cut and paste it from a note I copied from a forum entry to use at your discretion:
First post:
To enter "Service Mode" Press the remote - control keys in this sequence :
From Standby Info-Menu-Mute-Power On
- The buttons are active in the service mode.
Remote - Control Key : Power, Arrow Up, Arrow Down, Arrow Left, Arrow Right, Menu, Enter, Number Key(0~9)
Careful though there are things you shouldn't touch in this menu.

Good luck. Just a basic suggestion you probably don't need: keep track of any changes made by writing them down so you can put it all back if you have to.

Check its mechanism for fault.

Turning On and Standby
On the AV receiver, press the [ON/STANDBY] button.
On the remote controller, press the [RECEIVER] button, followed by the
[ON/STANDBY] button.
The AV receiver comes on, the display lights up, and the STANDBY indicator goes off.
To turn the AV receiver off, press the [ON/STANDBY] button, or press the remote
controller's [ON/STANDBY] button. The AV receiver will enter Standby mode.

If you have any trouble using the receiver, a simple reset could solve your problem.Note that resetting the AV receiver will delete your radio presets and custom settings.
To reset the AV receiver to its factory defaults, turn it on and, while holding down the [VCR/DVR] button, press the [ON/STANDBY] button. "Clear" will appear on the display and the AV receiver will enter Standby mode.


Hope you are satisfied with my solution.Your valuable feedback would be appreciated.Thanks for choosing Fixya.

Simple.
Press the Help button on the remote control for a minimum of 10 seconds while in standby mode. When the lamp time clock is reset to zero, the STATUS indicator goes out.

Place the receiver in Standby mode (press the front-panel Standby/On Switch so that the Power Indicator turns orange).
Then press and hold the front-panel OK Button on the Receiver ( not remote ) for at least five seconds until the RESET message appears in the display. Then press OK. The system will go to factory default. All your settings will be lost like FM stations / Sound settings etc: .

The remote control will not operate the TV when the TV is in the OFF mode (No LED lit on front bezel). To change the mode from OFF to STANDBY or ON, press the POWER button on the side of the TV. Once the POWER button is pressed, the LED will change to either red to indicate STANDBY or green to indicate ON, whichever mode the TV was in prior to being turned off with the TV POWER button.

By pressing the POWER button on the side of the TV, the mode will toggle from OFF to either STANDBY or ON. If the POWER button is pressed and then the LED on the bezel is red, the TV is in STANDBY mode and will need to be turned on using the remote control. If the POWER button is pressed and then the LED on the bezel is green, the TV is ON.
