Inspiron 6000 LCD Display Problem

Question

I know, everyone is tired of hearing about the LCD problems that seem to plague the Inspiron 6000. But I've searched the threads and cant find anything to help. I will go into detail for you.... Running Windows XP Pro Graphics are Integrated using Intel Chipset Family Desktops are cloned. My back light went out awhile ago (so i thought) and I heard a loud buzzing noise coming from the inverter. So logically, I ordered a new inverter. To my surprise, this did not fix the problem. The inverter seemed to be working fine. I ran the diagnostic test on the display and got the following results: (by the way, I did all this by holding my mini-mag behind the panel. worked pretty good) Video Card Connection Test Test Result Pass LCD Inverter Test Test Result Pass LCD Connection Test Test Result Fail Error Code 1000-0321 Msg Unable to detect LCD So, I took the whole notebook apart and reseated every single cable in the thing. No dice. I read about the magnetic switch malfunctioning, so i took off the bevel so that I could lay it on the palm rest and see the reaction to my LCD when i 'close the lid.' Even with everything set to 'Do Nothing' when I close the lid, my secondary display goes black briefly then returns to the desktop. My LCD panel, however, completely shuts off. hmmm. Seems a bit strange to me. So, Just to see what would happen, I used the Intel program for display settings to set my notebook monitor as the secondary display, and my CRT as the primary display. When i went to apply the setting for extended desktop, I received a Windows stop error, better known as 'The Blue Screen of Death.' I've searched to find the error codes and their meanings on Dell's website and come up with nothing. I am not really interested in 'fee based service' so I'm hoping someone can give me some much needed insight. On a side note, I am not really happy with Dell's customer service as they seem to have no faith in their own product. Even when my computer should have been under warranty, it wasn't (the 6000 was a replacement for an older model that kept having a problem, so instead of giving me a new warranty for the 6000, they left me with nothing, not even giving me the option to extend my warranty.). I don't think i will ever purchase a Dell again, and probably should not have bought one in the first place. You know, a MacBook Pro sounds really good right about now. Anyway, if you have any insight, please let me know. After searching the threads and reading about other peoples experiences, I do not think this is a problem with the back light or the display itself.

The backlight alone won't produce a diagnostic error - the panel is bad (or the system board is, but if you can get an image on an external display, the board is fine).

I understand that the backlight will not produce an error. I think that I may have failed to explain that I still get an image on the panel but no back light. Honestly, it sounds like a driver error, even though you don't necessarily need a driver for the panel. I want to know why it gives me an error in pre-boot test even when I can still see the image on the screen. You see, it tells me that no LCD is detected, but it still shows the image. I don't think I'm quite ready to say that the panel itself is bad. Especially when I have read about people replacing panels and still having a problem. I'm just trying to get to the bottom of this whole issue. Thats all.

You've got one of two faulty parts: the panel or the system board. If an external monitor shows a good image, it implicates the panel (but bear in mind that the signal to the panel and power to the inverter passes through the system board, independent of the external display, so the mainboard may still be bad.

Hello,

I recently had the DC jack repair performed on the system. After a couple months, the problem occurred again, and would not take a charge. Upon the last bit of charge, it went into standby. I turned the machine back on, and the display flashed, clicked faintly once and powered down for good.

Is this problem related to the one above?

Thank you (very frustrated, and don't want to get taken advantage by a computer repair outlet - initial DC repair cost $200!)
