Lost audio & video

Your RCA LED50B45RQ TV appears to have a problem with the display and audio.
When the TV is turned on and the remote is used, the standby light illuminates, and the screen flashes white on the left side without audio or video.
Various factors could be to blame for this problem.
A few troubleshooting tips are provided below:

1. Check the connections: Make sure that all the connections between your TV, cable box, or streaming device are securely plugged in.
2. Check the settings: Ensure that the TV is set to the correct input and that the cable box or streaming device is set to the correct output.
3. Check the backlight: Some TVs have an adjustable backlight setting. Ensure the backlight setting is turned on and set enough.
4. Check the cable: If the cable that connects the TV to the wall outlet is damaged, the TV won't turn on. Try unplugging the TV, waiting a few minutes, and plugging it back in.
5. Check the power supply: The power supply could be malfunctioning. It could be damaged or not provide enough power to the TV.
6. Check the Main Board: The main board controls all TV functions. It could be malfunctioning, which is causing the TV not to turn on or display correctly.
7. Contact the manufacturer: If none of the above solutions work, it may be necessary to contact the manufacturer for further assistance. Your TV may require repair or replacement.

no, you need the remote to access the setup menus

I think your TV was set to turn off by itself automatically. Try to reread the manual about it.

Hello
Panasonic TV's after 1996 can be set to "Serviceman Mode" with the
following remote control sequence:

-select the SET-UP icon and select CABLE mode.
-select the TIMER icon and set the SLEEP timer for 30 minutes.
-press the ACTION button twice to get out of the menus.
-change to channel 124.
-adjust the volume to minimum (0).
-Hit the VOL down button on the TV itself (not on
the remote) and a red "CHK" should appear in the upper corner.
-press the ACTION and VOLUME DOWN buttons (again, on the
TV, not the remote) you will toggle between AGING and SERVICEMAN modes.

Select Serviceman mode. The POWER button on the remote control will
select one of the five Serviceman Adjustment modes.

The modes are:

B - Serviceman VCJ SUB Adjustments. These include sub-tint,
sub-color, sub-brightness, sub-contrast, colorkiller/ABL/gamma,
audio and video adjustment, and vertical size.

C - Serviceman VCJ Cut-off adjustments. These include Red, Green
and Blue cut-off, red and blue drive, automatic fine tuning
(AFT), RF AGC (RF gain control), horizontal center, beam limit,
etc.

S - Serviceman Options Adjustments. These involce the PIP and
clock.

M - Serviceman MTS (Stereo/SAP) adjustments.

CHK - the mode you first entered. Normal picture and sound, lets
you check things over and still have a hotkey into the
service menu.

There is one more adjustment that isn't in the five modes, it's
global. When in either the yellow or red CHK mode, you can press
RECALL on the remote control to enter the purity field check mode.
This lets you select a pure white, red, green, or blue screen. A
good thing to walk away from if you just want to temporarily freak
out the floor manager, but it will be fixed as soon as the TV is
turned off. Oh well.

To get out of Serviceman mode, press ACTION and POWER on the
receiver simultaneously for at least 2 seconds. The TV will momentarily
shut off and then comes back on.
