Having problems with your Sony VGN-CR220E/L Notebook ?

Sony Vaio Display problem

\015 I am using a Sony Vaio VGN-CR220E and starting a couple of days ago, the display has been very dim; so dim that it is hard to even determine if the computer is on. From most angles, it doesn't look like the screen is displaying anything, the only way I can use it right now is connecting it to my tv via the s-video output, or using a flashlight on the screen. I have tried everything I can think of, I have adjusted the brightness, changed the battery settings, plugged it in, adjusted several other display settings, and nothing has worked. I finally went to Sony.com and they said I needed to update my video driver, but that didn't work, then they said to do a system restore, and that didn't help either. Can somebody help me?\015

Hi,

Since the Sony Vaio VGN-CR220E works except that the display is dark, then it\015\012would be safe to assume that it is only the LCD display part that is\015\012the issue. Often LCD display (of laptops) are working but only that you\015\012can not see the actual display. One way to verify is to shine a flashlight\015\012at an\015\012oblique angle to the screen, semblance or part of the desktop could be\015\012seen s what you have done. If the\015\012desktop could be seen (albeit very very dark background) then it could\015\012either be the CCF Lamps (cold cathode florescent) or the inverter that\015\012powers the lamps.

Often, the defective component would be the inverter. It is\015\012relatively easy to replace the inverted. It is sometimes more difficult\015\012and challenging cracking open the casing of the display panel of the laptop than replacing\015\012the inverter. Additionally, inverters are readily available online. It\015\012is also not surprising that inverters for other brands/models would\015\012also be used in your Sony Vaio VGN-CR220E .

Of course another possibility is that there is just a loose connection or a cold solder in the LCD panel display's circuit boards.

This would be a good place to start for inverter boards. This is a nice tutorial if you are considering a DIY.

Hope\015\012this be of initial help/idea. Pls post back\015\012how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
The wire to the inverter is very short on this model. If you drop the unit it will likely come disconnected.
You can remove the plastic bezel around the screen and this see connector. It is easily reconnected. The store where I purchased my unit said it would cast $200 to replace the screen
