From: don on 3 Mar 2010 16:51 My Dell INspiron 8600 laptop screen began flickering this morning, now the screen is totally black but sometimes I am able to bring it back for a few minutes so I Know the pixals are fine - what is the problem - how much would it cost to fix? I had sent this laptop back to Dell the last time the screen went black 4 years ago and the bill was $450? I can't afford that anymore....... please help I'm currently running another monitor off of the laptop so I know the video card must be good.
From: Barry Watzman on 3 Mar 2010 23:16 The most likely cause is a bad inverter (power supply for the fluorescent lamp inside the LCD panel). Not too bad, about $30 or so (+/- $20) for the part, if you are handy you can replace it yourself (CAUTION: It creates dangerous and in some situations potentially lethal voltages). Next most likely is the lamp itself. Normally, this means replacing the entire panel, but they are much less expensive than they used to be, you can probably find a replacement panel for about $80 (+/- $30). Actual replacement, like the inverter, is not too difficult if you have some technical training & experience. The chances that it's something else entirely are slim. don wrote: > My Dell INspiron 8600 laptop screen began flickering this morning, now the > screen is totally black but sometimes I am able to bring it back for a few > minutes so I Know the pixals are fine - what is the problem - how much would > it cost to fix?

From: Barry Watzman on 4 Mar 2010 12:10 Most likely, the inverter is starting and then failing. Follow the advice of the previous messages. don wrote: > "Barry Watzman" <WatzmanNOSPAM(a)neo.rr.com> wrote in message > news:hmnc6e$ll6$1(a)news.eternal-september.org... >> The most likely cause is a bad inverter (power supply for the fluorescent >> lamp inside the LCD panel).

Repair, before it becomes permanent, and takes other circuitry along with it. |
