V3.03.0 white screen


Does the white screen say power only? If so hit exit on the remote and turn off the tv. Then turn back on and it should be ok. If it is just a white screen and nothing else then either your main board or t-con board is defective.

How do you fix a white screen for a dell Inspiron 1100 lap top?


White LCD screen in a Dell Inspiron 1100 Notebook PC?

1) Loose connection of the video cable TO the LCD screen, and/or loose connection of the video cable TO the motherboard.

2) Bad LCD screen

3) Bad motherboard. (More specifically a bad graphics chipset)

To start the diagnoses to find out what the problem is, you will require an external monitor.

This monitor can be a CRT monitor (Looks like a small TV), or a flat LCD screen monitor that has a VGA cable.
(A CRT monitor is a VGA monitor also)

Example of a VGA cable, and a VGA port, (Connector on computer),

http://en.wikipedia.org/wiki/VGA_connector

The VGA port is on the back of an Inspiron 1100 Notebook PC.
It is Blue in color.

A) Laptop OFF, monitor OFF. Connect the VGA cable of the external monitor, to the laptop's VGA connector (Port)

B) Turn the external monitor on. If a CRT style allow it warm up.
Turn the laptop on.

By default, (Factory setting), the external monitor should show the graphics of the laptop.

IF Not;
There are 3 options available,

1) Internal monitor of the laptop - ONLY
2) Internal monitor of the laptop, AND external monitor
3) External monitor - ONLY

If there is NO display on the external monitor, (Display; To include a white screen);

A) Press the Fn key, and hold it down. Now tap the F8 key. (F8,CRT/LCD)

Still no display on the external monitor? Press, and hold down on the Fn key, and tap the F8 key again.

IF, the external monitor shows a white screen, Stop.
You have a bad graphics chipset. Option is to replace the motherboard.

IF, the external monitor shows graphics just fine, diagnose further.

A) Look to see if the Video cable is plugged in tightly to the motherboard, AND connected tightly to the LCD screen.

Dell Support > Inspiron 1100 Notebook PC > Service Manual,

http://support.dell.com/support/edocs/systems/ins5100/en/sm/index.htm

Click on - Display
Under the heading - Display Assembly, look at the partial 'photo' under the number 8.

On the left side where it shows two Philips head screws removed, is the Video Cable. Pinkish wire wrapped around a Light Blue wire.
Look at Number 9.
The display-feed flex cable is the Video Cable.

Make sure it is plugged in tightly to the motherboard.

Now go down to Number 10.
In the exploded drawing the number 7 points to the Video Cable.
(display-feed flex cable)

Shows the Video Cable disconnected from the motherboard, and going up to the back of the LCD screen.

Scroll down to the heading - Display Panel. This shows the connection of the Video Cable to the LCD screen.

Also;
The Video Cable runs through the left Hinge Cover.
Repeated opening, and closing of the laptop, may have damaged the Video Cable.

Observe the sheath of the Video Cable. (Outside wrap)
Does it appear damaged? Pinched? Torn?
Even if it does not, I suggest performing a continuity test with a multimeter.

Multimeter's function knob is set to Ohm's. (Omega symbol)
Positive probe lead (Red) is touched to one end of a wire going through the Video Cable.
Negative probe lead (Black) is touched to the other end of the wire.

Do not be concerned at this time with the Ohmage. Concern is to see if ANY reading comes up, not how much.

Perform a continuity check on all wires in the Video Cable.
(An economical, yet decent enough multimeter for this test, can be purchased for around $5 to $12. A multitude of store carry them. An auto parts store is but one example)

Video cable checks out?
The next suspect is the LCD screen.
However, read on.

Primer:
An LCD screen does not produce enough light by itself. It needs an additional light source.
A Backlight is the additional light source.

A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

An Inverter (Screen Inverter) is used to convert the power (Electricity) from the laptop, for the LCD screen, and Inverter.

90 PERCENT OF THE TIME the fault is the Inverter.

Example of a screen inverter for a Dell Inspiron 1100 Notebook PC,

http://www.nylaptopparts.com/index.php?main_page=product_info&cPath=91_95_125&products_id=547

An expensive (Read - Sensitive) multimeter can be used to check a screen inverter. Not something everyone has laying around, or access to. In this case I would suggest replacing the Inverter.

(The screen Inverter is also easily accessed, AND much cheaper in comparison, than the LCD screen. Again, 90 percent of the time the fault is the Inverter )

IF, the Inverter does not cure the problem, then the problem is the LCD screen.

Review;
Check the display with an external monitor. Display checks good, run a continuity check on the Video Cable.
Video Cable checks out OK, go to the Inverter.
Inverter does not cure the problem, the problem is the LCD screen.

BEFORE beginning to disassemble;
Remove ALL power to the laptop. Remove the AC adapter (Charger), and Battery.

Observe Anti-Static Precautions.
(I would also advise using an ESD wrist strap, and connect it's alligator clip to a good ground source.

Average cost of a decent ESD wrist strap, is around $3 to $6.
I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.
{Electro Static Discharge)

Use a multi-compartment container for the various screws you will remove.
label each compartment for the area the screw/s come out of.
If no multi-compartment container is available, substitute with a clean egg carton.
Label each egg holder.

SOME screws look VERY similar to other screws.
Do Not mix them up.

For additional questions, or to have me explain anything I have stated here, post in a Comment.

Regards,

I have a Sony DSLR A-300 and the lcd screen on the back of the camera goes white when I take pictures. How to fix this?


The camera has live-view, so is the LCD always white? Can you play back old pictures or view menus properly? Do your pictures turn out white or are they ok?

If it's always white and you can't see anything, you need the LCD replaced or the cable going from the main PCB to the LCD replaced. 99% likely the LCD, not the cable.

If you can playback old pictures and view menus... but NEW pictures turn out white then it's not a problem with the LCD screen at all, it's the CMOS or something else.

Without knowing more detail it's hard to say exactly what's wrong, but it definitely sounds like the camera needs repair.

Hi, my Logitech Harmony 1100 Universal Remote screen whent blank /white, is it possible to fix?


Hi. Firstly, I would not recommend trying to fix this yourself, as doing so would void your remote's warranty. The screen on my Harmony 1100 went blank once, and updating the firmware fixed it. Sometimes corruptions can occur on the remote that cause this issue.
To update the firmware on your remote, log in to the Harmony software and click "Downloads" at the top of the screen. Then, click "Firmware," and follow the instructions to update the firmware and configuration.

Ok i have an hd pc monitor and when i turn on i get a whit screen


dani. If you can verify your PC is working ok and capable of driving a known good monitor, you will at least narrowed down problem to your white screen lcd! Always state the make and model in the text body of your post to fixya. I usually only do BLACK screen fails, but here goes anyway. The vga input to LCD digital output interface board is telling the lcd panel to turn all pixels "ON" !! If monitor worked ok the day before--then it should work fine today? NO! something has changed! When strange things start to occur on lcd panel I would first suspect the "switch-mode-power-supply" as the trouble maker. If you haven't a clue as to how a SMPS does what it does, then you will need to find technician or TV repair shop that also knows forward and backwards all about lcd monitors. I do suggest that you visit youtube for videos on lcd monitor disassembly and LCD monitor repair so you can see what is inside a typical unit. FYI visit www.ccl-la.com/badcaps.htm and www.badcaps.net Well, anyway, your CCFL backlights STILL work!!
Although most of my responses are to Black/Blank screen you may find other options that will suit you a little better. 12fixlouie

Power problem


There is no exact name for this main board. All you need to know when replacing the main board is that the Insp 1100 and The Insp 1150 main board will fit. If you are going to change out the board, I suggest going with the board from an Inspiron 1150, it is an upgrade for the Insp 1100, and has built in wireless.

Its an LCD problem. if you have the means to take the phone apart, carefully remove the LCD assembly and clean its contacts and the circuit board pads. If its still the same, only a replacement can solve it.
