Hi scott, i am presently troubleshooting an hp pavilion dm4 laptop(win7 installed).
- all front panel led on
- gives the windows sound on getting to windows
- screen completely white(right from bios)
- got picture when connected to an external monitor.
The first thing to do is to backup the HDD.
Scott,can i conclude that the lcd has gone bad?the laptop is over a year old and out of warranty.thanks in advance!

It does sound like a failing LCD, but to be sure I would check the connection (disconnect and reconnect the cable). If that didn't help, then either a replacement LCD or a new system might be in order. These days eBay seems to be a good place to find laptop parts, so you might check there. Let me know what you find, Scott.

PS: Welcome to the forum!

Well I know this happens on laptops. If anyone own headsets. They tend to last a year or 2 then you have to replace them. It due to the wires are made of metal and wear out and break. It kinda funny to think how many Bose headsets my brother own over the years. I think the same concept applies to Laptop Monitors when you open and close the screen. The Wire wear out and break.

How do you figure that gigabyte?. Just wondering how you would come up with such a theory with the limited information available in this thread. It just seems kind of strange to me that you would be able to say what caused the problem or if there even was a cause, because sometimes laptop screens just go bad.

Gigabyte, I'm sorry to have to disagree with you, but, having just experienced a similar problem, (see my thread a couple above this one) I highly doubt opening and closing the screen stresses the cable to the breaking point after such a short time.

For one thing, the cables are highly protected at that point. For another, if that were the the issue you were having, replacing the entire LCD would have been unnecessary if only the cable was faulty.

So, unless the new LCD came with the cable attached, you really can't be sure which part was faulty: cable or screen.

Just an observation......
