I am trying to fix this problem with my wife's laptop and its really frustrating. Its Dell Inspiron N5030 and its just over a year old. Unfortunately the 1 yr warrantee has expired and this problem started happening for the past 2 -3 months. The problem is, when you start the laptop, it has a complete blank White screen. I have read quite a number posts around and many have suggested that this is usually a loose video cable connection, or a bad lcd video cable or a problem with motherboard. I will explain the steps I've done so far and hopefully someone here can guide me on what I can do next to resolve this issue.
First of all, when this problem started happening, it was very unpredictable. Meaning, sometimes the laptop starts fine but sometimes the white screen appears. But as the weeks went by, the white screen begins to appears more frequently and now it appears all the time. This is what i've found so far:
1) When connecting an external monitor, the external monitor works fine. The weird thing is, sometimes when I connect the external monitor, the laptop white screen disappears and the laptop lcd screen begins to function again. I had this as a work-around for a while. Everytime the white screen appears, I connect the external monitor and remove it when the laptop screen works again. But eventually this stopped working as well.
2) When the white screen started to come up all the time, I noticed that the problem goes away when I remove the outer cover of the screen. (the black frame around the screen that can be removed by pulling it from the screen).
3) Last week, I removed the lcd screen and took it apart to see if there was any loose connection at the back. I noticed there is no loose connection and the inverter was fine as well. However, I noticed that the black cord (of the video cable) that runs from the back of the lcd screen to the mother board was sorta jammed around the hinge area. I fixed this cord so its seated properly and made sure that the outer frame doesnt push this cord at the hinge when I put everything back again. When I did this, the laptop started to work fine for the next week without a problem but today the white screen started to appear again!!
So based on the what I've seen, I think that the cord is getting jammed around the hinge and hence causing this problem. But I am not a techinical person and not sure if its correct. Its just a guess..So I dont know what do I do next? Does it mean that the video cable is stuffed or is it just the jamming on the hinge causing this issue? Do I need to change the complete lcd video cable or is there another solution by moving this cord away from the hinge to fix this problem from happening? What do I try out next?
I appreciate any assistance and I thank you for taking your time to read my post.
Solved! Go to Solution.
Welcome to the community. I see that you did some troubleshooting steps. Sounds like a hardware problem. Its really hard to tell which specific part is causing the issue. I can tell that the issue is intermittent. Possible points of failure are the LCD Cable, LCD itself and the port in the motherboard where you plug in the video cable. I suggest to check again connectivity of cables. If this will not work, probably you need to replace the whole LCD kit.
Hope this helps,
thank you Elijah...I guess I will next try and see the connection of the LCD cable to the motherboard. I havent checked this connection to the motherboard yet since I guess I would need to dissemble the keyword and the other parts to get to it. I have just downloaded the servicer manual for this laptop model and I'll see how I go with it. fingers crossed!
Good thing you know computers well.
Yes you need to remove the Keyboard of this computer to reach the cable inside. Good thing you know computers well. Let me know if need assistance, Goodluck!
Its actually the first time I have dissembled a laptop and thank god I didnt break it! lol...
Thank you for your support Elijah..I just opened up the laptop base and checked the video cable connection to the motherboard. The cable was definetely not loose. If at all, it was actually pretty tightly secured. However, I disconnected the cord from the motherboard and re-connected it. I also re-aligned the cord that was running through the hinges. Like I had mentioned before, it appears as if the cords were jammed and flat around the hinge area and not sure if this was causing the video cable to not work properly and hence showing the white screen now and then since the white screen only comes up sometimes and not always. I've put everything back together and I tried restarting the laptop a few times and so far the problem hasnt happened yet. I need to wait for a few days and see if it slowly begins to happen again. Last time when I removed the bezel and re-aligned this cord on the bottom left hinge, it worked for 3-4 days and the white screen started again after opening and closing the laptop lid over the period. This time, I moved the cord coming from the motherboard and adjusted it a bit more and I'll see..finger's crossed.
If incase, the problem happens again, what is the next step I can try? Do I first try changing the video cable first and see how it goes? atleast the video cable is cheaper than changing the LCD. Also I doubt if the LCD can be faulty since when it works, the screen is absolutely fine with good clarity.
Thank you again for guiding me through this. Much obliged!
How's this solution working for you? I'm having the same problem. Have already replaced the LCD only to have the issue reappear (so to speak).
hi randypittes....sorry to hear that replacing the LCD did not solve it for you! thats a shame...changing lcd would have costed you quite a bit!
Fortunately the problem hasnt happened again yet but I dont want to get my hopes up too high as well.. It is still too early to say since this laptop hasnt been used a lot over the last week. In the past when I re-aligned the cord at the top cover near the hinge, I've noticed that the problem temporarily went away and it occurs again after the laptop lid has been opened and closed a few times (may after 30-40 times). Thats why I was guessing if it was the video cable at fault. Anyhow, if it happens again, changing the video cable will be the next thing I will try to do and its pretty cheap off ebay. I will post an update over the next few weeks.
What model are you using? Is it the same as me - 'Dell Inspiron 15 N5030'?
Same exact model. I inspected the cables and plugs when I had it apart -- everything looks fine. Problem is intermittant, like yours. Works fine on an external monitor. So, you replaced the LVDS cable and the problem hasn't returned?
It would seem that the video chip is fine if it runs an external monitor? It's also interesting that once you plug in the VGA cable the LCD works fine again.
In any case, please let me know if replacing the cable is still a good solution for you.
