Fixing Lost Brightness on an RCA Tablet




Introduction: Fixing Lost Brightness on an RCA Tablet

It has been brought to my attention (by my daughter who thought she had broken something) that some of the 7" Tablets using Android 4.X allow the user to turn the brightness down to a point where the LCD tuns off and will not allow you to see the screen to turn it back up....

Step 1: Unlock

Here are the measurement from my tablet. They should give a fairly good idea about where to find things on you screen. Remember, everything is right where you left it, you just can't see it. When you succeed in doing the right pattern in the right place, your tablet "should" make a happy unlock noise.

Step 2: Open the Menu.

After the happy unlock noise, swipe down from the upper right hand corner.

Step 3: Turn Up the Brightness

Using the supplied measurements, tap the area where the "BRIGHTNESS" button should be. The slider bar will appear for 5 seconds near the center of the screen. You shouldn't need to slide, just tap near the right side to get the screen bright enough to see. From there you can refine it!

    it MAY just be that it is turning the backlight off.

    In that case, shine a flashlight at the screen, at an angle. Too little angle and you still can't see. Too much angle, and you will get reflected glare. Just right, and you will be able to see the graphics faintly, looking almost like monitor burn in.

    If your child also messed with the contrast too much... well, factory reset is there for a reason.

    It is in fact turning the backlight off as you stated, sadly there is no on/off switch for this, only the brightness bar. As for the flashlight trick, modern anti-glare coatings on these tablets have have this very difficult to achieve although it is possible and finally, brightness is a peripheral setting, factory reset will not change it. (discovered this at my first attempt at fixing it!)
