This doesn't sound good, but there are a few things to do. First, if you replaced the screen yourself and feel comfortable opening up the case again, do so and check the connections. There might be something lose that's making the problem. I'm guessing not though. It sounds more like a logic board problem. You can try a few options though.

[]Reset the PRAM

[]Leave the battery out and the unit unplugged for a day and press the power button about 10 times to discharge the laptop. (sometimes does something to settings)

[]Hook it up to an external monitor to see if you have an image. This will tell you whether it's an internal thing or not. If you don't get an image on an external monitor, you probably have a bad logic board. Sorry I can't help more.

Dell Inspiron MINI 1012 Laptop Screen 10.1 LED flickers


soldbyajt,

It sounds as though the video card has gone bad in your system. There are a couple of things to try to eliminate the lcd.
If the LCD on the system shows no display or has other problems, here are some basic steps to take:
  1. If the LCD is not displaying any video, connect an external monitor to eliminate a no-POST problem. A good image on the external monitor eliminates a video card problem or a POST problem.
  2. Connect an external monitor when possible for all LCD-related problems to help eliminate a possible software or video card problem.
  3. If the LCD has lines on the screen, check the system during POST as well as system setup to determine if the lines are present in all modes of operation.

    If you cannot get any video by connecting an external monitor then your motherboard will need to be replaced. The reason for the motherboard replacement is because your video card is soldered onto the motherboard.

    Thank You,

Ferrari 1000 LCD failer


Hi, Your post "Would a failed Inverter on an Acer Ferrari 1000 cause the system to not recognize the installed LCD?" No,the inverter only provides the high freq high volt for the backlight. Monitor/LCD recognition is part of your video/display controller. Pls check your video drivers (ATI Radeon Xpress 1150). Also your Default Monitor Properties. Hope this gives you some idea, Good luck and pls post again how things turn up. Kind regards.

hi there!

hope you can give us more details on what happened before this problem started. but if you dropped the phone, try pressing the lcd screen's left and ride side, top and bottom too, see if the lcd screen responds. if not, it may need replacement. if it does respond, you still need to bring it to a techinician for they need to open it up and check if the lcd ribbon was disconnected or if it indeed need replacement. post back if you have more info for us to resolve the issue!

The source button is not responding even though the power shows each time i press but no response.


There are two possible causes. 1. The Function Buttons on the TV are shorted thus not allowing commands to be sent to the Main bd. Replaced the Function Button PCB.
2. The Main bd is bad.

The touch screen on my dcr-dvd108 will not respond anymore...


mine did the same thing, and i tried to reset it but that didnt work, my warranty had ran out and i didnt buy the store warranty,so i pretty much gave up on it as it still didnt work. well my wife got it and was determined to fix it. she saw some sand in the corner of the lcd, and took some paper and cleaned it out and now its working again! lol it was just a little sand in between the lcd and the lcd case causing it not to respond. try that or try some canned air to clean out the screen.

Sony DSC-W70 LCD Problem


You will need to describe what you see on the LCD in more detail in order for me to tell you what the problem is. There are two different issues that can cause things like what you are seeing. 1: Cracked LCD. You will see lines which resemble cracked glass. You will see bright vivid colors with specks of black or stark white all over. The image problems may be only in one portion of the screen. The LCD is made of glass, so if you look closely and see patterns that look like broken glass - this is your issue. Replace the LCD. 2: Bad LCD connection. You will see distorted colors, the screen may blank out and flicker when you shake the camera or press on the housing near the screen. If neither of these describe what you are seeing, post back and give more details and I will respond further. David Millier Advance Camera Repair
