The model of your Toshiba not only locks out using screws, plastic ridges are also closing the actual case. You may either carefully use a cutter blade to separate the casing or anything thin that will not damage the plastic case.

If I were you, I would first try a system recovery as it has crashed.
What's an inverter? Does it mean you have connected the power supply with wrong polarity? I dont think you need to open it.

Hpw2408h screen problems


if the half portion of the screen is only black shadow the the cause is either busted screen back light or a dry connector at the power inverter board. to access this part you will need to remove the back cover of the tv unit. the power inverter board installed near the power supply board and then the screen back light is mounted at the upper and lower portion of the panel display covered with metal shield.

I recently bought a Hp Lcd w1907 Monitor off craigslist, the screen worked fine for about an hour then went black, button stays blue. Now every time I power on the monitor it stays lit for 3 seconds...


hi the cause is screen back light not working properly. you need to remove the back cover of the monitor to access the internal part of the monitor. then look for the connector of the cold cathode fluorescent tube back light going to the power inverter board of the back light you will noticed a dry joints which cause a loose connection that is why you hear a sound that cause of spark. you need to re soldered the connector or replaced if totally burned.

Computer wont start in any mode, black screen


Look at the battery indicator light on your computer. Is it on? If so, check your brightness settings. If your laptop appears that it is not on, it may in actuality have 1.lowered brightness settings. If the brightness setting is at its lowest setting, the laptop screen will be completely dark, and the laptop will appear to be powered off, even though it is not. Try cranking up the brightness settings.

2.Check your AC power adapter. Is it snugly plugged into the wall or surge protector? Make sure the connection is made and it is not loose. Also, try connecting the power adapter into a different wall outlet.

3.Check the status of your laptop battery by considering how long you have had the same battery. Most modern batteries are only good for about 1,000 full charges. After that point, the battery can and eventually will greatly deteriorate. Replace your battery if necessary.

4.Replace your battery by powering off your laptop and then flipping it over and locating the battery cover outline, which will be near the bottom back of your laptop. Remove any screws with a Phillips screwdriver and pop off the battery cover. Slide out the old battery. Put in the new battery by sliding it in until it clicks, and then replace the cover.

5.Consider replacing your laptop monitor. Your laptop may power on, but if the monitor display does not work, it will appear to be off and you will not be able to operate the machine. Check to see if your current LCD display works by plugging your laptop up to an external monitor using a VGA cable. If the external monitor displays your computer contents, your computer motherboard and underlying systems are still working, but your display will need to be replaced.

6.Replace an LCD display by removing the screws around the bezel of your current display with a Phillips screwdriver. Pop off the bezel carefully and remove it. Then, locate the screws on the two metal brackets beneath the bezel and on either side of the display, and remove these too.

7.Disconnect the inverter cable, which is plugged into the inverter. The inverter is located just beneath the display, at the bottom-center of the laptop. Then, pull back and slide out the old display, and replace it with the new. Put the metal bracket screws back in place, reconnect the inverter cable, and then pop the bezel in place. Replace the bezel screws.

LCD screen totally white when turn on


The HP is a flat screen monitor used with many desktop computers. When the LCD on your HP monitor goes white, it is an indication that your monitor's inverter board has gone bad. The inverter board is a small circuit board that transfers power from the monitor's main circuit board to the LCD screen. Replacing the inverter board means dismantling the HP monitor.

1. Power down your computer and unplug the HP monitor cable from the back of your desktop. Disconnect the power cable from the back of the monitor. Relocate the monitor to a flat work surface. Place the monitor with the screen facing downward.

2. Remove the Phillips-head screws from the monitor's base stand and from the back cover. Lift the base stand off of the monitor and remove the back cover. Peel away the foil from inside the monitor around the internal circuit board.

3. Locate the inverter board near the bottom of the monitor's casing. Unplug the power cables from either side of the inverter. Loosen the Phillips-head screws from the inverter board. Lift the old inverter out of the monitor's casing and set it aside.

4. Place the new inverter inside the monitor. Replace the Phillips-head screws and fasten it in place. Reconnect the power cables to the connectors on each side of the new inverter. Replace the foil around the outside of the main circuit board.

5. Replace the back panel and base stand, and their retaining Phillips-head screws

I hope you find it very helpful.

My screen has gone totally black. rebooting


The most likely problem in this situation is that the inverter is burned out. Do you hear sound? If your computer boots and there is sound, it is definitely the inverter board. You might want to try to replace the inverter board. I think it's about $15 on ebay. If you are tech-savvy you can take the computer apart. The inverter is usually located below the LCD screen. for more info on replacing the inverter click here http://www.insidemylaptop.com/remove-lcd-screen-inverter-board-hp-pavilion-dv9000-laptop/

The screen was black when turned on but could make out what was on the screen when facing the light


You have 1 of 2 issues...

1.) You have a Bad LCD Bulb.. You can get a replacement LCD Bulb and change the LCD Bulb inside the Display which is cheaper and easier than replacing the whole backlight panel.... LCD bulbs cost around $12 Be careful these bulbs are Fragile and if bent when installing- will break...

2.) You have a failing Power Inverter... this is located just under the screen display panel,, it is a circuit board that the screens lcd bulb plugs into and the display cable plugs into... this inverter board converts the DC power in the laptop back to AC power because the screen needs more power to power the lcd bulb...

Your Problem Is One of These 2 Things... Your Best Bet Is To Test The Power Inverter First - Since It Is The Easier Of The 2 To Replace/Repair

Monitor goes blank


I was thinking about your problem, I just had a similar issue and the problem is that the inverter or the power supply with an embedded inverter had gone bad.

The reason it goes black is because the inverter fails to provide power to the LCD Display.

The only way to fix this is to open up the FPD:

*note these are instructions for the most popular FPD 1730*

1.there should be four screws on the back --> plus two large screws that hold the FPD stand and the Monitor together.

2.Open the back by pulling the cover off
Remove 7 screws holding the frame and the power button for the LCD

3.Remove two screws through holding a silver cover and remove cables.(pinkwhite) (blackwhite)
Please note where they belong before removal**

4.On the edges left and right are two screws 4 total ---> remove and remove LCD off of frame**becareful because the backlight Damaging can cause severe damage to your LCD panel.

5.Choose your model
Your FPD has 3 boards (power, inverter(backlights) Logic Video)
replace the inverter with well known good one

Your FPD has 2 boards(Power with inverter on edges, Logic Video)
replace the power board with a well known good one

6.Then do steps 1-5 in reverse order(putting your FPD back together.

I hope this is significant help

I have repaired 3 Viewsonic VP211b monitors.
The power light comes on but there is in picture. In all three cases it was the same problem. It was a blown fuse on the inverter board.
1. The monitor must be opened: The black plastic back is pried off carefully. It is easy to damage or crack. This will expose the electronics.
2. Remove the metal covers: The power main board has a metal cover that is secured with 4 screws. When that cover is removed, you can then remove the cover over the inverter.
3. Remove the inverter: The inverter is held with 1 screw. There are a total of 6 pairs of wires to the fluorescent lights (3 on each side) that must be disconnected from the inverter and a there is a power and control cable to the main board that must be disconnected. The inverter should now be free.
4. Test the fuses: On the inverter there are two tiny surfaced mounted fuses, labeled F1 and F2. They are on either side of the power cable CN1. Either one can be blown. Test them both with an Ohmmeter.
These fuses are 1.5 mm long, 1.0 mm wide and 0.5 mm high (Case Style 1206). They have the letters FN printed on them. The N is for 2 Amps and the F is for Very Fast Blow.
I replaced them with the same fuse, except Fast Blow rather than Very Fast Blow. The replacement fuse has just the letter N. The FN was not available at the time and I felt the N would be close enough. The fuses were made by LittleFuse. They were purchased from Newark Electronics. Part number 64R8010.
Prior to acquiring the surface mount caps, I tested the inverter board by soldering a regular fuse across the blown fuse and putting the inverter back into the monitor. The monitor came back to life. Normally when there is a fuse blows, it is because there is a short someplace down stream. How ever the new fuses have held. Therefor I am assuming it was just faulty fuses.
With the new surface mounted fuses, the repaired boards were placed into monitors and they all worked.9486ec61-dd3d-4a22-bbc3-82b55a458b09.jpg00ad0ac3-9cf1-4fff-83ed-90d93e6a0e0a.jpg40cff7a9-f7c7-4904-aac3-eb656a117911.jpg0ee0c7e1-1e8a-4b07-936c-83557d5ddd2b.jpg3ccdb800-f497-41ee-b268-cad6a2330191.jpg4d8ec0f3-f0e3-4e06-bc47-791b2996f04b.jpg
