I would take a look see at the ground circuits for the none working lights . The incandescent back lighting lamps are then grounded at G200, G301 and G302. You would need factory service info for the location of the grounds .Like this from buick
Right side of the I/P, secured on the underside of the cross car beam, behind the I/P compartment . The I/P compartment is the glove box ,don't know why they just don't say that . You could also check out the power and ground from the componet that's not working ! You can find factory like service info. from alldata http://www.alldata.com/ . Check out some videos on youtube
Interior Lamps Dimming
The second group includes lamps which may be dimmed. This group may use a combination of vacuum fluorescent (VF) illumination and of incandescent lamps.
• The door switches and the window switches
• The HVAC control head assembly
• The radio
• The instrument panel cluster (IPC)
• The steering wheel controls
• The heated seat switch
• The HUD switch
• The lift glass window release switch and traction control switch
When the ignition switch is turned to the ON position, the vacuum fluorescent (VF) displays (radio and HVAC control assembly), incandescent lamps, turn on at maximum brightness. When the park lamps are on and the ambient light sensor indicates low light conditions, all incandescent back lighting turn on at the dimming level indicated by the IP dimmer switch. At the same time all vacuum fluorescent (VF) displays dim to match the indicated dimming level. The BCM L fuse in the console fuse block, supplies battery positive voltage to the BCM. The I/P courtesy lamps supply voltage circuit of the BCM, supplies battery positive voltage to all the dimmable lamps. When the headlamp switch is placed in the PARK position, the BCM will then dim the interior lamps to the dimming level indicated by the IP dimmer switch. When the driver selects a dimming setting by moving, the IP dimming switch potentiometer, all incandescent back lighting lamps are provided with a specific voltage. The incandescent back lighting lamps are then grounded at G200, G301 and G302. When the IP 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 IP dimmer switch.
The driver may select parade mode by manually turning on the park lamps during daylight conditions. The front park lamp circuit supplies voltage to the instrument panel cluster, radio and HVAC assembly for a park lamp on input, and the displays will become full bright.
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.
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.
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.
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.
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.
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.
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.
