Faceplate display backlight out

My Sony car stereo's display went "dark". Since I can still (barely) read the messages, I presume that it was a broken backlight. Does anyone know how to replace the light bulb (if any?) in the faceplate? Any other possibility (e.g., power supply?) JP

I had the same problem. I took the faceplate apart. There are 2 LED's on each side of the LCD display on the faceplate main board that illuminate the LCD display. One of them was burnt out on mine. I replaced it with a green small LED, however the light output is not at the same level as the remaining orginal LED. The original green LED looks like a high output white LED that was covered with a thin green coat. Not sure where you can get those.

Your display lights are burnt out. This is a common problem. It is covered under warranty. Send it to Sony for service. Anyway, under the Sony faceplate there are two small, different colored leds which control the color. The light is aparently transfered through pieces of clear plastic (best example I can think of is the piece of plastic over the led in a household smoke alram)to most of the buttons and the backlighting. If your display has burnt out you may just be able to swap the leds for new ones. As for the intermittent green could it just be a faulty solder on the board.

I have replaced my old broken display, the camera works but the light of the display dont work. Its very dark.

The backlight is a different device located below the display. It is supplied with a high voltage (about 100V) over a separate cable. In case of the W55 both flat cables are soldered together and have one multi contact connector on the main board.
Check this connection first - the flat cable should be clean and completely inserted.
If this dosn't help: is the backlight of the broken display still working? It's a bit tricky but possible to disassemble the display, remove the backlight desolder and exchange it.

My sony vaio vgn-n365e screen is Dim

The fault could be a faulty CCFL lamp or inverter.
To determine if you have a LCD screen, inverter or video card problem, read this and follow these 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 the monitor up first then the laptop, 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.

Phone display is very dim-can barely read

Well, first you will have to check your options, if you can read it enough to get in there.  You may have the backlight turned off.  If the backlight is not turned off, then you probably have a bad backlight and will have to take it to your provider to get it fixed.  Replacing a screen/backlight is not something I would attempt to do unless you are certain you know exactly what you are doing as you can render the phone completely useless.

Sony CD Mavica MVC-CD400 display/backlight faint/not working

If you already tried to adjust brightness and it didn't work, problem is backlight inverter which is part of DC board or it might be fuse on DC board related to inverter. Anyways, camera needs to be serviced.

Dark screen

if the picture is REALLY dark, like you can just barely see it in a lit room, then the backlight might not be lit. LCD TVshave backlight that shines through the LCD screen which allows you to see the picture.

If it's not the backlight then it would be the brightness/contrast settings that need to be adjusted. If the picture used to be normal and all of a sudden went dark, verify the backlight. Normally you can look through the slots on the top of the set and determine if the backlight is on. If you can see a bright light through any of the slots, the backlight is probably OK... go after the brightness/contrast settings.
