If you olny getting white glowing screen, it can be the connector to the T-CON board on the LCD panel came off or it has blown fuse on the T-CON board, or the logic board is not sending the 5 or12vdc to the T-CON board.

How would the pattern on the screen change if a pure blue screen were substituted for the white screen?


What can you do if the laptop LCD screen turned completely white? 1. Loose connection between the video cable and the LCD screen.
2. Defective LCD screen.
3. Defective motherboard (I assume the graphics card is integrated into the motherboard). Here's an example of a laptop with white screen. When you turn on the laptop, it starts but the image on the screen is completely white right from the beginning.

Most likely you still can use the laptop with an external monitor. Just connect the monitor to the VGA port on the back or side of your laptop and then switch the video output from internal to external mode.

On Toshiba laptops you can toggle between internal and external screens using Fn+F5 keys. Hold down Fn and press on F5 until you get video on the external monitor.
On IBM laptops use Fn+F7.
On HP laptops use Fn+F4.

It's possible that you have to use a different key combination on your laptop but you get the idea.

On some laptops, in order to be able to use the external monitor, you have to connect it to the laptop and then restart the laptop so the external monitor is detected by the laptop. In some cases the laptop screen may turn white because of poor connection between the video cable and the LCD screen. If you want to check this connection, you'll have to take apart the display panel because the connector is located on the back side of the LCD screen.

These laptop service manuals and disassembly instructions may be useful. Always check the video cable connection first. Reconnecting the video cable may fix your problem.

If reconnecting the video cable doesn't help, most likely you have a problem either with the LCD screen or with the motherboard. The best way to find out witch one is causing the problem is testing the laptop with another working LCD screen. you will need to connect to another monitor or your television to your computer with the vga lead monitor connection click start control panel display change display settings adjust resolution this may vary depending on your operating system you should see a no 1 and a no 2 with detect and identify keep an eye on the screen when you select the number tabs this may vary depending on your operating system when you select the no 2 tab this should be the extended desktop always click apply after making any changes or click start control panel administration tools computer management device manager scroll to monitors right click select scan for hardware changes if you can get an extended desktop your monitor is faulty if you cant get an exended desktop

My pc is showing a white screen when iys on


Is it an LCD monitor ?
When an LCD screen has turned completely white, there are three normal causes: the screen is defective, the video cable is not connected correctly, or the graphics card on the motherboard of the computer is faulty. You will need to troubleshoot these possibilities to determine which problem you have. If you are not experienced in working on computer equipment, you should not attempt to disassemble your LCD screen because you could easily damage it. Seek professional assistance unless you have experience working on computer hardware.

Disconnect the white LCD screen from the computer by unscrewing the blue monitor cable. Connect the working LCD screen to your computer by attaching its blue monitor cable to the same slot. If your computer display does not show on the functioning LCD screen, try rebooting your computer. If it still does not display, the problem is with your computer's graphic card on the motherboard. Seek professional repair assistance. If your computer display shows normally on the working LCD screen, proceed to Step 2. Unplug the LCD monitor with the white screen. Disassemble the rear panel of the monitor with the small screwdriver. Carefully separate the screws into piles so that you can keep track of how to reassemble the monitor. Locate the internal video cable, a gray cable with a plug on the end that connects to the main components of the screen. See Below for the References section for photos of the video cable for assistance. http://www.laptoprepair101.com/laptop/2008/04/13/laptop-lcd-screen-turned-white/ Unplug the cable, checking for any debris or blockage. Reconnect the cable firmly. Reassemble the LCD screen. Plug it in and connect it to your computer. If the screen is still white, you have a defective LCD screen. You will need to replace it or take it to a professional repair service for assistance. Hope this helps.

Lenovo Y410 white screen


All that's left is the Video Cable, and LCD screen, Aberger.

Video Cable connections are tight? LCD screen side, screen Inverter, and motherboard side?

Then a continuity check with a multimeter set to OHMs, for each wire in the cable, or take to a 'Mom and Pop' computer store, and have the tech check it, or replace.

Video Cable checks out, connections check out, the LCD screen is the problem.

My money is on a bad LCD screen, JMHO.

Gateway FPD1750 monitor's keep go black screen, no picture at al


tgordon60, If you know how those NEW "CURLIE-Q" energy efficient CFL light bulbs produce WHITE LIGHT, then you will know what makes an LCD display panel produce all the pretty colors and the WHITE BACKGROUND of the FIXYA web page!!! Only difference is that your "cold-cathode-fluorescent-lamps" are thinner and straight, and hung on rear of LCD glass panel and have a DC to AC electronic ballast called an "INVERTER" circuit to produce 600 to 1000vac to light them up. Get to my FIXYA profile and read my responses to other BLACK screen lcd owners to learn about all your options for repair. Follow any of the links to other web pages you find there. Your monitor not any different than ACER, DELL, VIEWSONIC, BENQ, SONY, AOC!!!!! 12fixlouie aka louie12fix

I have a samsung 15 inch LCD TV. When I turn the


kcs36dd, Lcd TV's also have, just like LCD monitors, an AC to DC voltage power supply. It is called a "switch-mode-power-supply" and generates the DC voltages required for all the other important electronic circuits inside the unit. 98% of all 14" to 22' lcd panels have backlighting provided by "cold-cathode-fluorescent-lamps" (CCFL) that produce WHITE LIGHT so you can see all the pretty colors that the glass LCD PANEL produces on the screen. The INVERTER circuit requires 12vdc to 20vdc from the SMPS to convert into 500 to 1000v ac to light-up the CCFL's. IF the SMPS detects a FAULT CONDITION with itself or the INVERTER it will go into what is known as FULL or PARTIAL SHUTDOWN MODE to try and save itself from a catastrophic, nonrecoverable failure. e.g. sparks, smoke, fire. lmistyrel on aim.com I could give you more assistance if you had provided following informatiom.
1. How old is the unit? 2, Approximate total "ON" hours unit has? 3.Has unit failed within the WARRANTY period? 4. Will SAMSUNG do a cash+old unit swapout because of PREMATURE FAILURE? 4. Do you know enough to do a unit TEARDOWN and inspection to possibly determine ROOT CAUSE of SMPS/INVERTER failure? 5. Can you handle a soldering iron and solder to make DIY repairs to unit. 6. Since your unit is just a little more complex than a LCD MONITOR, have toy viewed on YOUTUBE short video clips of "LCD monitor disassembly" or "LCD monitor repair" for the most common cause of BLACK screen complaints? If further assistance is required do additional post to original. 12fixlouie aka louie12fix on fixya

My TFT LCD Monitor, serial #MT-NI-DYLM2286 produces a light pink backround, but prints clear. Is there some way to return the monitor to a clear white backround?


rjmusvi, Sometimes the VGA connector at the rear of the PC needs to have it RESEATED 4-8 times to see if it returns the screen to NORMAL colors being displayed on the LCD panel!!! Do this with the POWER OFF to both PC and LCD monitor!!! Also check to see if any of the pins in the monitor to pc plug are bent or pushed down into the connector body. 12fixlouie on fixya

The hp f1703 will display for 3-5 seconds and go balck


rking3905, Please tell me if F1703 is BOTH BLACK and BLANK, or if it is just BLACK! If the screen is BLACK and you can see the WIN-desktop with aid of flashlight held 1" from the screen then the monitor's "switch-mode-power-supply" is in partial shutdown mode having detected a FAULT condition with the "cold-cathode-fluorescent-lamp" power supply called an INVERTER circuit (12vdc to 600-1200vac) to light-up the lamps hung on the rear of the LCD panel which produce WHITE light so you can see the image or text displayed on the LCD glass panel. In any case, you or a technician will need to evaluate the true state of your monitor. Also try to view some video clips on YOUTUBE that deal with "LCD monitor disassembly" and "LCD monitor repair". The longer (8-12min) clips are best. FYI goto www.ccl-la.com/badcaps, www.lcdparts.com, www.badcaps.net for more information on what may be the cause of your BLACK and or BLANK screen! If this was of some help, please rate this response on fixya.

What is the LCD Blue Backlight, and its function on LCD monitors?


johnsona881, Backlights for LCD monitors are called CCFL's, and are not blue!! They light-up the reverse side of the lcd panel with WHITE light. Cold cathode fluorescent lamps are what allow you to see what is on the screen. They are straight tubes (2) hung horizontally left to right and if the inverter circuit can't produce 600- 100volts ac you will have a black screen to look at!!! 12fixlouie
