Black Screen on Dell Inspiron Laptop
I have recently fitted a new LCD panel to a Dell 1545 Inspiron Laptop as well as a new inverter. When i boot it it gives a quick flash on the screen and thats it. I have tested the panel on the inverter on my packard bell and it lights up ok. I have an output to an external monitor too.
When i ran the dell diagnostics, it came up with a Error Code 0321-LCD EDID - unable to access EDID EEPROM.
The inverter passed ok. The HDD also failed on a error code 0142- self test unsuccesful status 70.
the computer boots into vista ok on the external monitor, but there is only a flash on the laptop screen when you try to switch back over to the laptop.
when i checked the BIOS the version is A10 but the LCD panel was listed as unknown.
Could it be the wrong panel? it seems to me that the power to the inverter is being switched off as it only gives you a quick flash on the screen and thats that.
Can anybody tell me what the EDID EEPROM fault is?
Incidentally the laptop was sat on thats why the screen needed replacement.

I don't know what the error means but are you sure the screen is compatable? That model requires a 15.6" HD screen, not the standard 15.4" WXGA type.

Hi all, thanks for the help so far, the BIOS does say under panel type - Unknown device installed, so that indicates to me that its not being recognised in the BIOS, so maybe a BIOS update might help.
As for the EDID are you saying that the EDID and the BIOS information are connected, as the panel is not being recognised by either vista or at POST and the EDID cannot be accessed by the dell diagnostic program.
I understand if the panel was lit until vista kicked in that would indicate a corrupt driver or registry item possibility, but as it only gives a very quick flash of light at POST I would say its more likely to be a BIOS problem initailly at least.
Does anyone have a link to an updated BIOS for the 1545, the version I have is the A10.
Thanks

Seeing that the new screen worked in the Packard Bell it is most likely the wrong one for the Dell 1545. Flashing the BIOS is not going to help. You will have to change the Display Adapter for the screen to work. That's not really an option.

Thats what I think, may be better to send the panel back and make sure the next one is compatible with the laptop. it is the 15.6" type the model is a 156WA01S make is CHUNGHWA made in china.
Not sure of the panel which Dell use as I didnt take out the old panel.

Right thats very helpful news thanks, do you know the make and model I should have for the Dell?
A Phillips screen is LTN156AT01.
Look at these on ebay for other compatable models.

The solution was only partially complete as i have not had time to exchange the screens yet but the comments make sense with the problems I am experiencing.
