Dim LCD on sony str k870p

If the dashboard mileage light on your 2001 Buick Regal LS is very dim and the Service Vehicle Soon (SVS) light and antilock light stay on, there could be a few potential causes for this issue. Here are some things you can check:

1. Dim dashboard light: If the dashboard mileage light is very dim, it could be due to a burnt-out bulb or a problem with the dimmer switch. Try turning up the brightness using the dimmer switch, and if that doesn't work, check the bulb and replace it if necessary.
2. SVS light and antilock light: The SVS light and antilock light staying on could indicate a problem with the car's computer system or with the antilock brake system. It could be caused by a faulty sensor, a wiring issue, or a problem with the computer itself. It's recommended to have the car's computer system scanned for error codes to determine the root cause of the issue.
3. Battery or charging system: A weak battery or faulty alternator can cause electrical issues in the car, which could be related to the dim dashboard light and the warning lights staying on. Have the battery and charging system checked to rule out this possibility.

moved you from Computers to TV ( A 2007 MADE TV)
now maybe get answers, yah think? sure.
I WILL ASSUME CLICKER HAS FRESH BATTERIES AND BRIGHTNESS MOVED MAX AND ANSWER.
ALL MODES OF VIDEO DIM,


some old TVs do DIM with age, for sure OLD CCFL BACKLAMPED
TV OF ANY KIND,
THE MANUAL WARNS
LAMP(S) INSIDE THIS PRODUCT CONTAIN MERCURY
THAT MEANS CCFL TUBES. INSIDE AND ALL DIM WITH AGE AND MOST THIS OLD ARE EVEN DEAD.
CLUE #2 IS IT HAS A CCFL INVERTER BOARD,
THIS IS NOT A LED BACKLAMPED TV AT ALL./
ALL ARE DOOMED. (20K HOURS USED AND DIM IT GOES)_ OR WORSE
THERE IS YOUR ANSWER AND SAME THING ALL TV.
2000 TO 2010 YEARS WITH ROTTEN CCFL TUBES.
BUY LED TV NOT CCFL. OR OLED

The LCD display is failing, or the driver ic is the issue, or the B+ is to low causing the dimming effect, a resistor gone high in value would explain this.

Hello
The problem is with its backlight inverter board. there are some step-up transformeres [small ones] fitted on board. If any one's core bacome loose this fault will occur. Just open the TV and listen to which one makes hi-pitch noise. Replace it, if you can buy it from the electronic market at your town. In most cases, the inverter board needs replacement.
This board can locate on the right or left side of the panel, fitted vertically.

This switch is designed to dim incandescent lamps. It has nothing in its description about being used with CFL (compact fluorescent lamps) types. If you are attempting to dim standard CFL types, it will not work.

CFL's are available in both dim-able and standard types. As you may have guessed, only those marked as "dim-able" will work with a dimmer switch. Dim-able CFLs cost slightly more than standard CFLs but may be controlled by any switch. Dimmer switches may only control incandescent and other type lamps that specifically state they are compatible with dimmer switches.

If you are attempting to dim incandescent lamps, make sure that you are not trying to dim lamps with a total wattage greater than the dimmer can handle. Most dimmer switches are rated for 600 watts, if you have two dimmer switches under one wall plate, the wattage rating drops to about 500 watts. This de-rating is because of the heat the switches create. There are dimmer switches that can dim more than 600 watts, but the price skyrockets for a 1000 watt dimmer, and keeps climbing.

If your wattage is within the limits of the dimmer, check the bulbs. If they are ok, the dimmer may have failed and require replacement.

If you found my reply helpful, please rate it "4 thumbs up". Good luck & thanks!

Is it equipped with auto dimmer sensor? When it sees oncoming headlights it would dim the brights automatically.

Ur LCD inverter board it dead,change that board.It a long board.

Are all of these not working ?
• Air temperature switch
• Cigar lighter lamp
• Door switches
• Driver information center (DIC) switch
• Headlamp switch
• Head-up display (HUD) switch
• Heated seat switches
• HVAC control assembly
• Instrument panel cluster (IPC)
• Memory function switch
• Radio
• Steering wheel controls
• Window switches

Interior Lamps Dimming
This group of interior lighting includes lamps which may be dimmed. This group uses a combination of class 2 controlled illumination and incandescent lamps:
• Air temperature switch
• Cigar lighter lamp
• Door switches
• Driver information center (DIC) switch
• Headlamp switch
• Head-up display (HUD) switch
• Heated seat switches
• HVAC control assembly
• Instrument panel cluster (IPC)
• Memory function switch
• Radio
• Steering wheel controls
• Window switches
For the interior lighting to be dimmed the following conditions must be met:

Here is a discription of how they work ,factory service info.
• A low light level has been detected by the dash integration module (DIM)
• Headlamp switch is placed in to the PARK or HEAD position
• Ignition switch is placed in the ON position
Then all class 2 displays and all incandescent back lighting will be illuminated to the level set by the instrument panel (I/P) dimmer switch. When the I/P dimmer switch is moved from MIN to MAX, all class 2 displays and all incandescent back lighting respond from minimum intensity to maximum brightness.
The DIM supplies battery positive voltage to the coil side of the PRK LP relay in the rear fuse block.
When the I/P dimmer switch is moved from MIN to MAX, then the instrument panel module (IPM), W/CJ2, or climate control panel (CCP), W/C67, applies a message to the class 2 communication circuit to the DIM. The DIM then applies a ground to the park lamp relay control circuit. This energizes the PRK LAMP relay and allows battery positive voltage to be applied through the DIMR fuse to the DIM. The DIM then illuminates the following incandescent lamps through the incandescent dimming output circuit:
• Cigar lighter lamp
• DIC Switch
• Headlamp switch
• HUD switch
• HVAC control assembly
• IPC
• Radio
• Steering wheel controls
The DIM also applies a message to the following class 2 controlled illumination components:
• Drivers door module (DDM)
• HVAC control assembly
• IPC
• Radio
The DDM will then send a message through the simple bus interface (SBI) to the RH front door module (RFDM). The door modules will then illuminate the following components through the incandescent dimming output circuit:
• Air temperature switch
• Heated seat switches (W/KA1)
• Memory function switch (W/A45)
• Power door lock switches
• Power window switches
The ground for these components are provided from the DDM and RFDM.
The following components are grounded at G200:
• Headlamp switch
• HVAC control assembly
• Radio
• Steering wheel controls
The following components are grounded at G201:
• Cigar lighter lamp
• DIC Switch
• HUD switch

Having the vehicle checked for DTC'S - diagnostic trouble code's would probably be your best course of action .
DTC B2556 (1)
The I/P dimmer switch is a potentiometer. The instrument panel module (IPM) determines the control setting based on the voltage from the I/P dimmer switch. The IPM sends out a class 2 message to the dash integration module (DIM). The intensity of the interior backlighting shall be adjustable when ever the park lamps are on. The intensity of the vacuum florescent displays shall only be adjustable when it is night and the park lamps are active.

DTC B2628
Circuit Description
The I/P dimmer switch is a potentiometer. It is powered by the HVAC control module. The HVAC control module determines the level of dimming desired based on the voltage from the I/P dimmer switch. The HVAC control module converts the I/P dimmer switch feed back voltage to a digital signal and puts it on the Class II communication bus.

Dash Integration Module (DIM)
The DIM is wired to the class 2 serial data line. The various DIM input and output circuits are described in the corresponding functional areas as indicated on the DIM electrical schematics.
The DIM functions include the following:
• Control of headlights and exterior lamps
• Horn relay control
• Interior lamps incandescent dimming
• Lamps On signal with wiper/washer
• Power moding control over Class 2 serial data line
• Steering wheel controls
• Storage of the clock settings and, sending a message out on the class 2 serial data circuit in response to requests from other modules

Your best bet ,take your vehicle to a qualified repair shop.

The display will dim for certain features that are not available for use in your current configuration or current operation.
For example; if you do not have an antenna plugged in then the selection for the tuner will be dimmed on the display.
