Question about Sharp Televison & Video
The auto-dimming is from the OPC (light sensor) control on the Sharp LC-65UE630X. Enter the menu and go to the TV setup portion of the menu system. Select the Picture sub-menu and set OPC to Off. This is shown on page 3-3 (page 24 of the PDF). Sharp has the manuals for their Android TVs here: https://global.sharp/aquos/en/androidtv/support/ . The direct link to the manual for the LC-65UE630X is currently https://global.sharp/aquos/en/androidtv/support/download/UE630X_65_58_50/UE630X_Series_user_manual.pdf .
I hope this helps. If you have a different model, please add a comment with the full model number. I believe the light sensor dimming will be in the same place across most Sharp models. I would only be able to confirm this with the model of your set.

Why does my sharp Aquos TV go out of resolution everytime I turn off the Wii game that is hooked up to it? Then I can reload Optimum cablevision- all I get is the program guide. Help

First off a little tip that manufacturers don't tell you is that you HAVE to TURN OFF the POWER to ANY UNITS that you are Connecting to via HDMI!!!!!!! If not you can short out the Inputs!!!!!!!! HDMI is usually Automatic, But sometimes you need to go into the Menus on all Devices to the HDMI section and write down their settings and compare them. Any definition that you are not sure of check the Manual or Google it! Match all the Settings (there won't be Much!) Hopefully the Inputs were not Damaged it only takes one time to short it out and then the Repairman makes a few bucks! Good Luck!

If the TV goes in standby, then it is in protection mode.
Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.
1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.
If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem
On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.
On Rear Projection : check lamp, lamp ballast, power board, and convergence.
On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

I had the same problem, but it looked like my son pressed the view mode button on the remote. I set it back to Dot by Dot and it looks perfect again. Try it out.
