Sound like the lamps are ageing or the lamp PSU is playing up.

How to replace the switch on the lights in the steering wheel of a 2006 chevrolet silverado

Before you start replacing parts ,need a little more information . Maybe able to save you some time an money . Does the horn work when you push the horn button , does the air bag light stay lit in the instrument cluster ? The button lights for the bottons on the steering wheel are lit by the BCM - body control module . Interior Lamps Dimming
The second group includes lamps which may be dimmed. This group may use a combination of vacuum fluorescent (VF) illumination and incandescent lamps.
When the ignition switch is turned to the RUN position, the radio's vacuum fluorescent (VF) displays turn on at maximum brightness. When the park lamps are on, all incandescent back lighting turn on at the dimming level indicated by the I/P dimmer switch. At the same time all vacuum fluorescent (VF) displays dim to match the indicated dimming level. The panel dimmer switch potentiometer is an input to the BCM. When the driver selects a dimming setting by moving the I/P dimming switch potentiometer, all incandescent back lighting lamps are provided with a specific voltage. When the I/P dimmer switch is moved from MIN to MAX, all vacuum fluorescent (VF) displays, as well as all incandescent back lighting respond from minimum intensity to maximum brightness in response to the I/P dimmer switch.
The following switches and components have back lighting when the park lamps are on:
• The instrument panel cluster (IPC)
• Radio, front and rear
• Window and heated seat switches
• Garage door opener switch
• Selectable ride switch
• Roof beacon switch
• Power take off (PTO) switch
• Headlamp leveling switch
• Rear wheel steering mode select switch
• HVAC control assembly
• Headlamp and panel dimmer switch
• Transfer case shift control switch
• PSIR disable switch
• PRNDL lamps
• Traction control switch
• Steering wheel control switches
• Fog lamp switches

Could be the clock spring inside the steering coulmn ,under the steering wheel if horn doesn't work ,air bag light lit etc...

Mitsubishi TV 65 inch rear projection. WS 65809 I went thru the convergence ic chip replacement years ago. Love the TV. My problem now is that the brightness goes from full bright to full dim then...

The old Mitsubishi units had a super capacitor in the logic circuit instead of a backup battery. This capacitor became leaky over time, causing the problem you describe among others. Number one symptom is set has audio and dark or black picture when powered up. As the super cap charges to full voltage, picture comes and goes.

On my 1999 Olds Intrigue I have never had to turn on my lights at night. All night time driving lights come on automatically until recently. Now only the headlights come on.To get the dash lights,tail...

Without testing i would say you have DRL control module problem , But that would just be a guess .
In the night mode, the DRL ambient light sensor senses darkness. Then, the DRL module turns off the front turn lamps and turns on the headlamps through circuit 10. The DRL module also turns on the park, side marker, license, and tail lamps. If the engine should stall with the DRL control module in the night mode, the DRL control module will turn off the headlamps and leave the side marker, park, license and tail lamps on while the engine is being cranked. The headlamp switch operates as usual.
The Daytime Running Lamps (DRL) control module is designed to automatically operate exterior lights depending on outside light conditions. The DRL control module operates in two modes, the day mode and the night mode. In the day mode, the DRL ambient light sensor senses daylight. Then, the DRL control module turns on the front turn lamps (non-flashing) if under the following conditions:
• The ignition switch is on.
• The headlamps switch is in the OFF position.
• The park brake is released.

The brightness of the Vacuum Fluorescent (VF) displays is controlled by two signals: the park lamps on signal (circuit 230) and the VF dimming signal (circuit 308). With the park lamps on, the VF display of the radio, heater, A/C control (with RPO CJ2) and the instrument cluster will dim for nighttime viewing. When the park lamps on signal is not present (park lamps off), the VF displays are at high brightness for daytime viewing. When the park lamps are on, the I/P lamp dimmer switch provides a signal (VF Dimming Signal circuit 308) which controls the brightness of the VF displays when the I/P lamp dimmer switch is adjusted.

Do the Daytime running light's work ?

This could be one of two things. The backlight is dimming. There are tube lights in the unit and they slowly burn out. The way to tell is if the picture turns a shade of orange slowly comes on to full brightness. It could also be the inverter. The inverter is the board that powers those lights.

My Samsung DLP HD tv's picture is starting to go dim. What can I do to make the picture bright like it used to be. Model Code - HLS6187WX Thank you for any help you can provide. Spencer

Has the lamp ever been replaced? As lamps age they get darker screens. First though check to make sure the TV settings aren't accidentally on a dark setting. Go into the menu and see if increasing the brightness helps.Different picture modes like movie, games, vivid have different brightness settings vivid usually the brightest.

Tv brightness/vibrant

Most of the projection lamps are recommended to be replaced after 2 years. The older they get the more dim they will become. I would suggest replacing the lamp again. Some of the aftermarket lamps do not work as well as the factory replacement. I always spend the extra money and get one from Samsung.

Hello have a low light setting on my AG-DVX100BP that wont allow the video to show?

Hit the iris button on the side of the camera, then use the dial to dial the iris into an open position and let more light in. Know that the higher the number, the less light coming in, so 16 is just below closed iris, 2.8 is just before completely open iris. The iris is like the pupil of your eye. You should always be in manual iris to control the iris with the iris dial, keeping the video between 4.0 and 6 usually gives you the best exposure (not too hot or too low light.)

You also may have a neutral density filter on. You should only apply this switch if there is too much sunlight. Use nd 1/8th for moderate sunlight, nd 1/64th for bright sunlight. Then adjust the iris with the dial again to get the best picture exposure.

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.

Pictures are too bright when shooting outdoors in sunlight

Have you tried changing your settings manually to outdoor? Or adjusted the aperture? You can usually find the aperture settings under the menu button. If not, try adjusting to outdoor conditions and disabling flash. And also, lower your white balance a good bit.
