Re: white screen lcd display
Your LCD is starting to go out. Call their repairs dept to have it fixed. 1-800-706-2534 option 2. Tell them that you have already talked to tech support otherwise they will make you call a bunch of different phone numbers.
A 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

This sounds like the inverter which powers the display fluorescent has or is failed/failing. If you take a torch to the blacked out display can you see the image faintly? If so the unit needs repairing.
Perhaps some moist came behind the glass? perhaps some air? Try to live with it, because the result is what counts and the pictures don't have this problem. I think it will cost far to much to bring it to a service or repair centre. Use the money to buy a new camera what this no longer shoot pictures.
You likely have a LCD set there which may likely use a back light inside to light the image, get the room as dark as you can and with a flashlight illuminate the screen from a angle, with set on if you can see the faint image on the screen of the program you have a Backlight issue'
1. Voltage not there or not being switched on for backlight.
2. Actual back light bad.
If the image can be seen with a flashlight one of the above is the issue and your "picture will appear very faintly" also suggests this.
In the example given there are 9 Backlights shown. Click on the Backlight images to enlarge)
An Inverter is used to change the power from the laptop, and provide power to the LCD screen, and Backlight.
90 Percent of the time the Inverter is bad.
An Inverter is a small circuit board, and is located behind the Bezel, and usually at the bottom of the LCD screen. (The thin plastic 'frame' going around the front of the LCD screen, is the Bezel)
If faint images are seen with the flashlight, replace the Inverter.
If you post the laptop's manufacturers name, and Model Number in a Comment, I may be able to give you a link to a free Service Manual detailing how simple it is to replace an Inverter.
I could also give links to possible choices for an Inverter. (The Model Number is on the bottom of the laptop)
2) If no faint images are seen there is a problem with the graphics. This could be due to something as simple as a Display Video Cable, or the graphics chipset itself. (Not so simple)
The Display Video Cable comes from out of the body of the laptop, and usually runs next to one of the hinges. It then leads up into the Display Assembly, and attaches to the back of the LCD screen.
Constant opening and closing of the laptop may have damaged the cable, or could have sightly unplugged it. The first thing to try would be to see if the cable's connector has come loose. The next thing would be to check the continuity of the cable, and if damaged replace the cable.
(The continuity of the cable can be checked with a multimeter set to OHM's. An economical multimeter can be purchased for as little as $10 to $12)
There is also a Display power cable that goes to the Inverter. With some laptop models it is incorporated into the Display Cable. This cable can be damaged by opening, and closing the laptop repeatedly, or become loosened, and slightly unplugged.
(Some laptops are designed where this is never a problem. Other laptops are designed where this can be a frequent problem. Poor engineering design)
2A) There are some laptops, specifically the HP Pavilion dv2000 series, dv6000 series, and dv9000 series that have a problem with the graphics chipset is overheated. Poor cooling design inside the laptop.
1)Work on a table Laptop off, remove ALL power. Remove the AC adapter (Charger) and Battery.
Observe Anti-Static Precautions, and remove the Ram Memory module/s. Clean the gold plated contact pins on the bottom of the Ram Memory modules with a pencil eraser. Both sides.
If you do not use a solid eraser, refrain from letting the metal band on the end of the pencil touch the contact pins. Use air to remove the eraser dust. You can use air from a can of compressed air for computers if available, or air pressure from your mouth will be sufficient.
Reinstall the Ram Memory module/s. Close the Memory Compartment Door. Reinstall the Battery Plug the AC adapter back in.
Wait 1 Minute, turn the laptop on.
2) Laptop on use a flashlight, and shine it on the LCD screen at an angle. Move the flashlight around. Do you see faint images?
3) Laptop off. If you have a VGA monitor available, plug the VGA monitor into the VGA connector on the back of the laptop.
Turn the VGA monitor on, then turn the laptop on. Toggle the display over to the VGA monitor by pressing, and holding down on the Fn key, and then tap the F5 key.
Do you see a display on the VGA monitor?
The two above simple tests will tell you if the problem is the Display of the laptop.
In 1) above if there are faint images seen, this means either the Backlight, or Inverter is bad.
An LCD screen cannot produce enough light by itself. It needs an additional light source. A Backlight is used to provide the additional lighting.
A Backlight is a CCFL. Cold Cathode Fluorescent Lamp (Bulb) Similar to a Fluorescent light bulb used in homes, and businesses, but on a MUCH smaller scale. (About 4 inches long, and half the diameter of a pencil)
An Inverter is used to provide power to the LCD screen, and the Backlight. An Inverter increases power from the laptop for the LCD screen, and reduces power from the laptop for the Backlight.
90 percent of the time the problem is Inverter failure. The Inverter is a SMALL circuit board located inside the Display Assembly.
Looking at the LCD screen there is a plastic frame which surrounds the screen in Front. This is the Bezel. Right behind the Bezel at the bottom of the LCD screen is the Inverter circuit board.
This is an example, of what an Inverter for a Toshiba Satellite U305-S5097 Notebook PC, looks like,
Hi, It is problem of lcd screen that will be replaced to get correct picture view. Local camera repair shop will replace it or if you have expertise then can replace lcd screen by yourself. Let me know if you need part number of lcd screen for DSC-S930 camera. Thanks.
If camera shows Menu item or any on-screen display in LCD but no live view to take picture then it can be either aperture problem or defective ccd imager. And if you do not see any display icon in LCD then of course LCD section is bad or LCD back light is Off for some reason. Try to see faint image in LCD if it is totally blank by pointing good amount of light with flash light or some thing.
If you see a very dim image or black screen or flicking image on the LCD screen it means you have a backlight problem.
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. Check out www.lcdparts.net for parts, repair service and DIY info.
First, I would use a multimeter to verify that the power adapter is good. It should have an output of 14VDC. If it is working, the next step in verifing that it is a backlight problem would be to connect the display as normal and, with it powered up, shine a bright light on the screen at an acute angle to see if the desktop image is being displayed. If you can see the image, then it is probably the lamps or the inverter.
To remove the cover, remove the four screws attaching the base and after the base is removed the 2 halves of the cover simply snap together. Using a jewelers screwdriver, start at one corner and gently pry the front bezel away from the back, working your way around it. There are 4 locking tabs on each side and 5 on the top and bottom.
This display has 4 lamps, 2 each at the top and bottom of the display. This is the easiest display I have seen as far lamp replacement goes. At this point, all you have to do is disconnect the lamps wire from the inverter, remove the tiny screw, right below the point where the wires connect to the lamps, and carefully slide out the lamp assembly. Be very careful not to flex them while removing.
Check the lamps for burnt spots at the ends or physical damage. If the lamps look good then I would not rule out the inverter as the problem. At this point, if you are not familiar with electronics, I would seek help from someone who is.
