My laptop has been flickering on and off at times ( flickering is white ). I think it may be loose cable due to compressed air? But for now, I am not so sure if it is a hardware problem or a driver problem.. I have no idea on what is causing this flickering nor any way of finding out. Please help.

I have a Dell Inspiron 1501 and the LCD screen is going dim, however it's only the left side, not the entire screen. Also there have been times in the past few weeks when the battery is unplugged the screen turned off and would not turn back on when it was plugged back in. (yes I did check the settings to make sure that wasn't an issue, it's not) Also anytime the battery is unplugged there is a high pitched whining sound. Any help would be great, thanks. Hi.

I have a HP Pavilion DV1000, I had a bad inverter so I replaced it, it works fine but only if the AC adapter is plugged in, shortly after it's removed the screen goes dim, I also may have a bad battery because even charged at 100% it dies in a few mins. Coud that be the problem? Hi.

In the right light and at the right angle, I can see the screen. It never flashes to full brightness at start up. However I am wondering if something else might be wrong because the laptop will not operate on an external monitor. What do you think? Is this the inverter or something else?

I am planning to go with the full display panels since they are much less likely to break in transport and are not that much more. Thank a lot.

It's buried deep inside the LCD screen and you can easily damage the screen during the disassembly process. I would consider buying the whole display panel witch includes LCD screen, inverter and video cable, check out <a target="_blank" href="http://rover.ebay.com/rover/1/711-53200-19255-0/1?type=4&campid=5335970148&toolid=10001&customid=lcd+went+dim+comments&mpre=http%3A%2F%2Fsearch.ebay.com%2Fsearch%2Fsearch.dll%3Fsofocus%3Dbs%26sbrftog%3D1%26dfsp%3D32%26from%3DR40%26satitle%3DInspiron%2B5160%2BLCD%26sacat%3D-1%2526catref%253DC6%26sargn%3D-1%2526saslc%253D2%26sadis%3D200%26fpos%3D95125%26sabfmts%3D1%26saobfmts%3Dinsif%26ftrt%3D1%26ftrv%3D1%26saprclo%3D%26saprchi%3D%26fsop%3D32%2526fsoo%253D2">these display panels</a>. <blockquote>Do they have different voltages or do I just need to get the correct length and diameter?</blockquote> Not sure about the voltage but you must get the correct length or it will not fit into the screen. I have a couple of different backlights with different connectors I removed from cracked screens. I use these backlights to test all laptops regardless the model and the brand, they always work fine. I guess any laptop CCFL bulb will fork fine with your screen as long as it has correct length. Just a guess. Robert,

It’s not easy to replace the CCFL bulb. It’s buried deep inside the LCD screen and you can easily damage the screen during the disassembly process. I would consider buying the whole display panel witch includes LCD screen, inverter and video cable, check out these display panels.

Do they have different voltages or do I just need to get the correct length and diameter?

This article and its links were very helpful. I do however have one more question. I have a Dell Inspiron 5160 that has a dim monitor and want to replace the Ambit t601828 inverter and the CCFL (this is because I am in the middle of Africa and a coworker is coming back from America so to be safe I would like to get both). I have no idea what CCFL to buy. Do they have different voltages or do I just need to get the correct length and diameter? Thank you. This article and its links were very helpful.

The screen went dim (but still visible) and would only become bright if I jiggled the computer a bit. I replaced the inverter but am still having the same problem. I'm not sure what to do next. If I hold the computer still it's fine, but if I partly move the screen up or down it loses its light. Help! I have an hp Pavilion dv1000.
