Automatic Brightness Issue

Does the ambient light sensor on the hx4700 only adjust a certain small percentage depending on light conditions. Mine only adjusts a very small amount up or down. Is this normal?

The automatic brightness feature is useless to me because of two reasons. First, it is too dark to start with. Second, it does not respond as fast as I like to see. I end up using only two default settings- Battery or AC mode.

I. Have 2 kkmoon cameras and one of them wet black and white .what can I do to make it color again?

1. If there is not enough ambient light hitting the sensor, the camera will record in IR / night vision mode. A cooler colored ambient light may also prevent the infrared (IR) cut filter from engaging, which can cause the camera to display in black and white.

2. The camera may be recording in night vision if it is not receiving enough power.

3. Evaluate the lighting condition. If the camera is in shade or a dark area it may be displaying in night vision mode. Adjust the sun shade and re-position the camera into different or brighter lighting.

Vizio smart tv, model E550i-A0, I have a dark screen and cannot adjust brighter.

Have you looked at the Vizio Manual? Page 23 has a few features that may need looking over.
  • "Smart Dimming- Improves the contrast ratio of the screen by adjusting the backlight intelligently. Select On or Off.
Smart Dimming may need to be set to off in order to adjust the brightness.

Here are a few more.
  • "Adaptive Luma" - Adjusts the average brightness of the picture to compensate for large areas of brightness. Select Off, Low, Medium, Strong, or Extend.
  • "Ambient Light Sensor" - The ambient light sensor detects the light levels in the room and automatically adjusts the backlight for the best picture. Select Off, Low, Medium, or High.

Good Luck.

Where is the ground for my 06 vue head lights at

The headlamps may be turned on 2 different ways. First, when the driver places the headlamp switch in the ON position, for manual operation. Second, with automatic lamp control ALC, and the headlamp switch placed in the OFF position.
The LH HDLP and RH HDLP fuse in the fuse block - underhood, supply battery positive voltage to both low and high beam lamps at all times. For manual operation , when the headlamp switch is in the ON position, the headlamp switch supplies ground directly to the headlamps and to the body control module (BCM) on the headlamp low or high beam signal circuit, depending on the position of the headlamp dimmer switch. The BCM uses this signal to determine if the conditions are present to illuminate the daytime running lamps or headlamps.
For ALC operation, the BCM receives a signal from the ambient light sensor indicating a low or high ambient (outside) light level. The ambient light sensor is a light sensitive transistor that varies its voltage signal to the BCM in response to changes to the outside (ambient) light level. Under the correct conditions the BCM grounds the headlamp relay control circuit energizing the headlamp control relay. The now closed relay supplies ground through the headlamp switch to the headlamps and the BCM on the headlamp low or high beam signal circuit, depending on the position of the headlamp dimmer switch. When the BCM grounds the headlamp relay control circuit, it also grounds the park lamp relay control circuit illuminating the park lamps. The headlamp relay is grounded at G203.
If the engine stalls with the headlamps in the ALC mode under low light conditions, the headlamps will be controlled OFF during cranking.
The conditions necessary for the BCM to activate the ACL mode are as follows:
• The ignition switch is in the RUN position.
• The headlamps are in the OFF position.
• The park brake is released.
• The BCM is receiving a low light condition from the ambient light sensor, if equipped with RPO T 82.

What are the two lights on the window dash

The one that flashes indicates that the car's security system is functioning properly (not necessarily that it is locked, though). The one that doesn't light is a sensor for ambient lighting conditions. It is used to turn on/off automatic headlights, or to adjust interior lighting for appropriate light levels, depending on how the manufacturer has it set up.

2006 grand Prix the drl stay on and will not go off if they do go off the come back on with nobody around the car keeps running the battery dead ????? Ready to burn it

Daytime Running Lamps (DRL)
The ambient light sensor is used to monitor outside lighting conditions. The ambient light sensor provides a voltage signal that will vary between 0.2 and 4.9 volts depending on outside lighting conditions. The body control module (BCM) provides a 5-volt reference signal to the ambient light sensor. The ambient light sensor is permanently grounded at ground G202. The body control module (BCM) monitors the ambient light sensor signal circuit to determine if outside lighting conditions are correct for either daytime running lights (DRL) or automatic lamp control (ALC) when the headlamp switch is in the AUTO position. In daylight conditions the BCM will command the low beam headlamps ON at reduced intensityy. Any function or condition that turns on the headlamps will cancel DRL operation.
There could be a DTC stored in the BCM pointing to a problem !
DTC B2645 Ambient Light Circuit


Turn the headlamp switch to the OFF position.
Do the low and high beam headlamps remain OFF?
Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems
Go to Step 3


Remove the appropriate low or high relay.
Do the lamps turn OFF?
Go to Step 5
Go to Step 4

My htc has a dark screen and still works and by dark i mean you can barley see any thing but sometimes the screen goes back to normal light

Is your phone a smart phone?? Does it have something called ambient light sensor (light sensor).??? Check your phone manual. If that is the case then you can turn it off. Ambient light sensor is a function that senses the light outside and automatically adjust the brightness of the screen. But sometimes it goofes up. So you can go to settings> display settings> brightness> if it is auto then turn it to manual as per your convenience. Again depending on your phone model the settings may vary. I hope this helps.

I have installed (or tried to) three different Leviton PR 180s in my front hall. All operated the 23 watt fluorescent bulb in the fixture satisfactorily, but were not affected by the ambient light; that...

The Leviton PR180 is a motion detector, or occupancy detector.
It senses infrared heat from a person's body.

I am looking at the manual from Leviton.

Maybe this will help:
There is a small adjustment screw under the wallplate where you can adjust light sensitivity.
Use fingernail or small screwdriver.
Turn control towards the "-" sign and lights will turn on in 'less lighting conditions'

I will be here for a few more hours.
