SOURCE: Mitsubishi WD-62527 replacement lamp install and brightness low

as i previously posted, my picture was dim, muddy looking after replacing lamp with osram lamp. i fixed mine by taking the screen off and cleaning the small mirror. it had a thick layer of dust on it, cleaned with a microfiber cloth. no water, no glass cleaners. i also used a very fine new small paint brush and dusted the projector lens which also had a dust film. brightness, contrast and clarity returned!

SOURCE: only brights work, dimly lit headlamps, no fog lamps

Recheck the bulb number. This happens when the wrong bulb number is installed. Otherwise it could be a bad headlight ground.

SOURCE: Backlighting issues on tv set (I think). Screen goes extremely dark after about 30 min. of viewing. Does not return to orginial brightness unless unit is left off for a long period of time

Lcd tv sets are lit by small glass florescent tubes called cold cathodes and, are powered by: ballasts called inverters... these go out just like your office florescent lighting the parts can be purchased online from electronic parts houses and, are easily replaced

SOURCE: Dim display ... no backlight

You most likely have a defective screen - a defective inverter or a CCFL lamp or simply the video cable needs reseating. After reseating the video cable and the problem is still there then :-
To determine if you have a LCD screen or video card problem, read this and follow the instructions.

Defective CCFL backlight, it may have the following symptom:

  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display or appear black.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

I have a Samsung 55in curved TV. It has auto dimming. In the evening with the lights out it dims to where it is difficult to see the picture. Can I get rid of the auto dimming?


If the brightness on your TV changes automatically (randomly dims and brightens), you may need to adjust the:
  • Eco Sensor function.
  • - And / Or -
    • Energy Saving function.
    The Eco Sensor and Energy Saving functions adjust the brightness of the TV to reduce power consumption.
    • When you set the Energy Saving function to Auto, the TV changes its brightness automatically depending on what you are watching on the TV.
    • When you set the Eco Sensor to On, the TV changes its brightness automatically depending on the brightness of the room.

My laptop gets dim from startup


Open the Control Panel, select Power Options, select High Performance, select Change Plan settings, adjust Display Brightness, Open the Advanced Power settings, adjust to your preference. On battery your laptop will decrease brightness, and other nonessential processes to conserve/extend battery time.

I recently purchased a 47"


Your TV has a light sensor that changes the brightness of the TV based on room brightness.


It's called an "Intelligent Sensor"

You can turn this off in your "Picture" settings.

Congrats on such a nice TV purchase.

If this was helpful, please rank me a 4.

When HP laptop is pluged into power source screen goes dim


Right click on the battery icon in the taskbar, go to Power Options or something similiar. Change the plan settings for the power plan you're currently in. Check the brightness ratio for both battery and plugged in mode. This problem might come if you or someone had tinkered with the settings.

HP dv1000 monitor just stopped working.


Description During the startup or boot process of the notebook, the display is very dim and barely readable. It remains dim when it reaches the Windows desktop. Restart the notebook with AC power Perform the following steps to determine if the dim display is due to a hardware failure:
  1. Connect the AC adapter to the notebook and a working electrical outlet.
  2. Power down the notebook PC by pressing and holding the Power button for 5 seconds.
  3. Press the Power button again to start the computer.
If the display is still dim after restarting with the AC adapter connected try changing the LCD brightness. Change the LCD brightness From the Windows desktop, hold the Fn key and press the F7 and F8 keys to increase or decrease the brightness of the display. If using the function keys does not resolve the problem, determine whether the Lid Actuator switch is stuck. NOTE: The key number may vary depending on the notebook PC. The image on the key should resemble the following images: Figure 1: Brightness Level Down c00776225.jpg Figure 2: Brightness Level Up c00776226.jpg NOTE: During battery power operation, the notebook display will dim to reserve battery power. Adjust brightness control using the control panel Some notebook PCs have the ability to adjust the brightness through video drivers. If the notebook PC has video drivers with this capability, perform the following steps:
  1. Click Start , Control Panel and then double click Display .
  2. Select the Settings tab and click Advanced .
  3. If the feature is available, a tab with the video card name will be present. If it is, select that tab.
  4. Adjust the desired brightness.
Finding the Lid Actuator switch The Lid Actuator switch is a small button or switch located above the keyboard and LEDs on the right or left side of the notebook. It may also be located near the display hinges. Pressing this switch when the computer is on may turn the notebook display off or cause the notebook to enter a different power state. Press the switch 2-3 times while observing the display. If the display is no longer dim the switch may need to be repaired. Contact HP service and support for further assistance. Contact HP service and support If the display remains dim after the troubleshooting in this document it may be possible that the backlight is damaged. Please Contact HP service and support to schedule a repair

JVC AV-27530 Sudden changes in brightness


This sudden changes in brightness are caused by the change in voltage inside the tv,not in the outlet in the wall but inside the set,The changes are an indication something is going wrong and it needs to be corrected,the set does have a brightness limiter but it only works when the set wants to get brighter than normal,You need the assitance of a servicer to correct this problem.
