Toshiba m35x starts /stops intermittently with no power to display monitor


By whom Kathleen? You?

I ask because there are two ways to answer this;

1) You performed the procedure, and less for me to post.

2) You did not perform the procedure, and I need to explain from the beginning; using a diagnostic flowchart, pictorial guidance, and guidance from me.

While I wait for your reply, suggest perform this simple test first;
Laptop OFF, monitor OFF, attach an external monitor;

1) VGA monitor to RGB (VGA) port on left side of laptop.
Can use a CRT type of monitor (Looks like a small TV), or flat LCD screen monitor if it has a VGA cable.

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

OR;

2) S-Video port on left side of laptop for TV, or external video display device

http://en.wikipedia.org/wiki/S-Video

Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

By factory default settings, the display should show on the external monitor. (Display device)

If not there are 3 display options available;
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external monitor
3) External monitor ONLY

Press, and hold the Fn key down, and at the SAME time tap once on the F5 key.
The F5 key is the Display Toggle-Over key.

Still no?
Hold the Fn key down again, and tap once more on the F5 key.

Display on external monitor means there is a problem with;

A) Video Cable
B) screen Inverter
C) LCD screen

Which means if computer display was working correctly before;

1) Whoever repaired it could have used the external display option, and it needs to be set back to internal

2) The Video Cable connections are not tight, not correct.

Loose at motherboard, screen Inverter, or LCD screen.

3) Anti-Static Procedures were NOT followed, and laptop is now an expensive paperweight.

Post back in a Comment.

Monitor is dark. how to fix?


Walt, hold the Fn key down again, and tap once more on the Acer, F5, Display Toggle-Over key.

There are at least 3 display options available;

1) Internal display of laptop ONLY

2) Internal display of laptop AND external display

3) External display ONLY.

Were you just using the external display for more 'display real estate room', or was/is there a problem with the internal display of the laptop?

Was no problem? Is now? Even when using the guidance stated above for the Fn and F5 key?

Then if your laptop uses a CCFL for a Backlight, it also uses a screen Inverter. Screen Inverter is bad.

If it doesn't use CCFL/s for a backlight, and uses LED backlighting, replace the LCD screen.
The LED backlighting is incorporated in the LCD screen assembly, and you ain't replacing it.
Replace the entire LCD screen.

Post the laptop manufacturer name, and model number in a Comment. Model number is on Bottom of laptop.


Try to hurry as I'm going to a meeting with the head of General Motors, (Obama), and later with Bill Gates.





OH I'M JUST KIDDING!

Acer aspire 8935g flickering screen on startup..even i see flickering when i go in bios setup...dos mode is flickering... kindly help... Thanks.


This is not a software problem. This is an hardware one. You have to replace the LCD inverter or to repair the existing one. The most common problem in the inverters is the age of capacitors. Im most of the cases if you replace the capacitors the problem is solved. This is working for any kind of LCD monitors and LCD television set. If you are a handy man you can fix it yourself by consulting the internet to see how it looks the inverter and where can be localized, how it looks a capacitor and where you can buy it, etc. If not a handyman try to ask a tehnician for help... Good luck!

I have a hp laptop. was on line and screen went black. and will not show again. it strats up sounds but black screen.what do i do


1) Do you have a VGA monitor that you can use for an external monitor?
{VGA monitor is also referred to as a CRT monitor. Looks like a small TV}

The back of the laptop, or side, has a VGA port. The VGA monitor is plugged into it.
{Laptop off}
Then the VGA monitor is turned on, and allowed to 'come to life'.

Now turn on the laptop. Press the Fn key down on the keyboard, and hold it down.
Now press the Monitor toggle over key.
Since you did not state the HP laptop Model Name, and Model Number, I can only give you generic guidance on this.

The monitor toggle over key has a monitor screen symbol on it. It will be one of the F keys.

(It's an External Monitor toggle key.
Press it one time and the display toggles over to an external monitor.
Press it again, and both the laptop LCD screen, and the external monitor have a display on them.
Press it once more, and the display goes back to the laptop's LCD screen )

If display shows up on the external monitor, you have a problem with the display of the laptop.

Primer:
An LCD screen cannot produce enough light by itself. It needs an additional light source.
A Backlight is used as an additional light source.

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

{Average Backlight is 3 to 5 inches long, and half the diameter of a No.2 pencil.
The Backlight is located on one edge of the LCD screen}

An Inverter is used to provide power for the LCD screen, and the Backlight.

90 percent of the time the problem is the Inverter.

Inverters are relatively cheap, and if I knew the Model Name, and Model Number of your HP laptop, I could give you a link to HP Support where you could download the Service Manual for free.

This way you would have a manual to show, and detail how to replace the Inverter, and I could guide you.

I could also give links for your perusal for Inverters.

There is one more thing however.

HP Pavilion DV2000, DV6000, and DV9000 series laptops, have a graphics chip overheating problem.
The laptop comes on, the blue indicator LED lights light up, but the LCD screen is black.

This video explains why, shows a solution to fixing the problem, and details out a lot more than I am privileged to state here,

http://www.youtube.com/watch?v=bnkQNmKauEc

Have further questions regarding any of the above, please state in a Comment.

I have 2 ibm thinkpads t40, on one of the systems the lcd inverter and screen get no power but when i take the lcd and connect it to the 2nd ibm tkpad it works fine, What would be wrong with the one lap...


On the second Thinkpad laptop, that doesn't show a display with an LCD screen.
Plug a VGA monitor into the VGA port on the back of the laptop.
Hold the Fn key down, tap once on the F7 key (Toggle your display over to an external monitor)

Give the VGA monitor a few seconds to come on. (It's a VGA monitor)

Do you have a display on the external monitor? No? You May have a bad GPU then. (Graphics Processing Unit,

http://en.wikipedia.org/wiki/GPU )

Fix? Change out the motherboard. Possibly Ebay has one, dunno.

VGA monitor has a display? Then you may have a bad Inverter. The Inverter provides power for the LCD screen. Inverters go bad.

Are both Inverters the same? (Laptop to laptop)
BE SURE. The Inverter MUST match the LCD screen!
Check the numbers on both Inverters. If they are the same, switch the good one over to the 2nd laptop. See if you have display now.
No?
Then it's the GPU.

Copy and paste the above link into your Address bar. Press the Enter key. (I don't post direct links that you just click on. I want the asker to be able to see where the link takes them, by looking at the link. I feel it helps make the asker more comfortable with my solution, knowing I have their best interest in mind.

See article written by sillybit (me) for the Westinghouse 19v5. My 20v5 had bad caps in the power supply - it did the exact same thing as yours. $8 worth of parts from radioshack and an hour or two is all mine needed.

Help in identifying this transistor for my VX924


Are they black with 3 SMD pads? They should have a tiny tiny number on the top corresponding to a SMD code that will tell you what they are (example: D9A means 5.5V zener diode).

http://www.tkb-4u.com/code/smdcode/indexsmdcode.php

You should be able to just get a new inverter or repurpose an inverter out of something else to get it working again. An inverter that powers any other CCFL bulb should work fine.

How to aply?


When a lcd monitor has a black screen the inverter is usall bad. Some have a individual inverter and others have a combination Inverter power supply. Capacitors are usally the first thing to check as well as fuses. Usally labeled starting with a F.
