Easynote tj74 wont turn on

The fact that you can see the desktop on the external monitor means your LCD Inverter on the laptop is bad. The video card in the laptop is good, otherwise you would not be able to see the desktop on either screen.

Shine a flashlight on the dark screen to see if you barely see the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.


The lcd inverter can be purchased on ebay for less than $15. It is located at the bottom of the lcd screen. You'll have to remove the plastic strip that is around the lcd screen by removing the plastic or rubber bumpers that have screws under them. Normally there will be bumpers at each corner and maybe along the insides on the plastic strip. Remove the bumpers, the screws and pry the plastic strip off with a little force with your fingers. You will then see the lcd inverter at the bottom of the lcd screen.

Just put your computer's name and model in the ebay search followed by lcd inverter.

Actually it looks like your laptop uses the LED screen instead of LCD so it will not have the LCD Inverter. You will have to purchase a new screen. I found the one below on ebay.

it is an issue with the LCD on your laptop as you get a fine display on external monitor
either get it repaired from a local technician
or get the LCD replaced

It sounds like your LCD might be bad. The fact that you can see the display on an external monitor tells you that your video card on the motherboard is ok. Is it booting all the way into windows so that you can see the desktop on the external monitor? Take a flash light and look real hard at the LCD on the laptop. Sometimes you might be able to faintly see the same thing you are seeing on the external monitor. If you can faintly see the icons or desktop that means your LCD Inverter is bad. If you see nothing, you screen probably needs to be replaced. I would find another repairman because you don't need to know anything about the bios to replace the lcd monitor. Look on ebay and type in "Dell Inspiron 1525 LCD Screen" . Set the options to "Buy It Now" so that you can only see the items you can buy and not bid on. Also set the Sort By to: "Price + Shipping Lowest First". The first thing you will see are LCD Inverters that can be purchased new for under $10, then you will see used LCD Screens from $50 - $75. A new LCD Screen for your system can be purchased as low as $86.69. Also notice that it shows that the screen will not only fit your dell inspiron 1525, but also the 1501, 1505, 1520 and 1526, so once again it sounds like you need to boot the repairman that says you need to know the bios number. If you need a good hones repairman try: http://www.generalsystemsconsulting.com They will fix it and ship it back to you for less than any quote you get including the shipping. I had a friend that got a quote from HP of almost $400 to replace the screen, they did it for $155

- try connecting an external monitor. if get a display on the external monitor then there is a problem with the LCD or the LCD cable on your laptop. if your still not getting video then try booting to BIOS (F2 or Del when you turn on the computer). if you are able to boot the BIOS troubleshoot the operating system. if not then you might need to get the video card or the motherboard replaced

Hi,

Outputting to an external display is only possible through Windows. As you stated External Display works with the computer, its sure that the issue is with the LCD. Performing a System Recovery is not going to help. The screen needs a replacement. To confirm this restart the VAIO and press and hold the F2 key and check if the computer boots to BIOS, if it boots to BIOS, then the screen is fine. Based on the information you have provided, I'm sure that the LCD will exhibit the same issue in BIOS and screen will stay blank.

As far as the recovery process is concerned, if you have not changed the preinstalled OS in the computer, you can still access the VAIO Recovery partition from Help and Support. You can also access the Recovery Center following the below link: C:\Progrm Files\Sony\Recovery Center.

To initiate a service process, you can visit the http//:eservice.sony.com or can get in touch with your favorite technician.

Hope this helps.

Thanks!!!!

Check to see if you have inadvertently hit the CRT button which turns off your screen to turn on an externally connected screen even if there is no external screen plugged in. OR you could have a bad (Back-light) or (Inverter)

When you say screen goes very dark when it booted to windows so it means that when you turned on the laptop when the dell logo flashes the screen was fine? if thats the case could you please try this. after turning on the laptop you will see the dell logo flashes immediately keep tapping on F2 and then it will show you the BIOS setup utility, please check if in BIOS setup display goes dark as well. If yes then try this, after turning on the computer when dell logo flashes keep tapping on F12 to boot menu then select utility partition to run the diagnostics. Please run test on the LCD check if display goes black when running the LCD test. Then try this when you sees the dell logo keep tapping on F8 to boot in safe mode check if in safe mode display goes very dark. Try this too, boot in F8 then select last known good configuration check if the settings on your display will be fix. If you can boot to safe mode no problem then uninstall the display or video driver. then restart computer.
You can also try to connect an external monitor if you have one just try to isolate if issue is on the LCD or the video card. If the display is dark as well in external monitor then video card needs to be reseated if fails then replaced. In situation like this most video cards is integrated to the motherboards. So replace motherboard.

Hello Gergerald,

To isolate the issue further connect the notebook to an external monitor and check the display on it. If the display is perfect on external monitor then the issue is with the LCD screen of the notebook.

If you have got the same lineds on the external monitor then the issue is with the video card of the notebook.

The BIOS is sending the display information to the monitor but, when you turn your PC on, the LCD will be sleeping and it will take 1~2 seconds to wake up when receiving the display signal. The monitor is working and even if the BIOS messages aren't displayed, you can still press the correct keystrokes to get to the SETUP screen or press PAUSE in the keyboard to see what's going on in the POST.
If your LCD has a bicolor LED indicating the status (Standby/On) keep looking at it, when the LCD gets the video data, the LED turns instantly from amber to Green or blue even if the screen is still black. This way you can have an idea when the LCD gets the initial video signal and to press the keys accordingly.
Your PC will also delay the video output from the secondary video card because it's detected after the onboard card.

I have seen this problem before, after booting to the external monitor go into the display settings and try setting the resolution to 1024 X 768 and the color settng to 16 bit or preferably 32 bit. If you can do this, then shut down the laptop remove the external monitor and try booting on the LCD display. BPCS
