Having problems with your Dell Inspiron E1505 Notebook ?

Screen goes black when plugged in

\015 The problem started gradually. At first it would go into sleep mode and have to be restarted. Then it started going black after 30 minutes or so (could still faintly see what was on the screen). Then if I plugged it in for even a minute or less it went black but worked fine on battery. Now it still goes black when plugged in and still works on battery but flickers and makes a high pitched noise for the first few minutes after starting it. I don't have an external screen to try it on.Any suggestions? Thank you!\015

Answers :

The high pitch sound is most likely a faulty inverter.\015\012\015\012Most defective screen are caused by a defective inverter or a CCFL lamp or simply the video cable needs reseating. After reseating the video cable and the problem is still there then :- To determine if you have a LCD screen or video card problem, read this and follow the instructions. Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case. The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills. Check out www.lcdparts.net for parts, repair service and DIY info.
