r/Dell on Reddit: Laptop mod and 2 amber 7 white error

June 17, 2024 -

Hi. I have a dell vostro 14 3468, BIOS version 2.3.0 and it has completely broken screen and case, luckily the motherboard still works normally.

I planned to turn it into a mini pc for home use, so I removed everything, only kept the motherboard, ram, ssd, then connected it to the monitor with an HDMI cable.

However, the indicator light flashes 2 times amber and 7 times white, it indicates a screen error and only works normally when connecting the device's screen via LCD cable.

Is there any way I can ditch the built-in monitor and use an external monitor via HDMI cable?

The 2,7 Error Code is LCD Failure, as you don't have the laptop screen plugged in.

r/Dell on Reddit: Dell XPS 15 9570 - Front LED Blinking 2 Amber and 7 White Flashes

June 15, 2019 -

Hi guys, I had a quick question that was giving me quite a bit of headache recently.

So, my XPS 15 is hooked up to an external monitor (stays hooked up to most of the time unless I need to take it out).

However, whenever I start up my XPS, the backlight keyboard turns on, but my screen on the XPS 15 stays black and then I see all my startup information and sign in information on my external monitor. All the while the front led is blinking 2 amber flashes and 7 white ones. I've tried to turn on my XPS without connecting the external monitor but then I see nothing at all, it stays black and the front LED continues to blink. I've searched the front LED codes and it seems to be an LCD failure but I m not sure how to exactly fix this.

It's very frustrating, because it seemed to have fixed itself a while back, but now it's happening again :(

Any help is appreciated, thanks!!

Hi,

You can try initiating the system diagnostics by following the steps in this link below: https://dell.to/2WHTOmB Let us know if you are able to initiate the test. Also, you can try to run a system LCD test as well to check if the LCD is working fine. LCD BIST: https://dell.to/2WK6rxB Try moving the system LCD to and fro gently to check if there are any changes. ^SK

RAM issue, visually inspect it to see if any chip looks damaged on the sticks If no visible damages, install one at the time and see if anything changes If nothing happens after the test you might need new ram, if even with new ram fails, it’s a Motherboard issue

Hi @divyendusingh · It's an LCD panel issue. · Most likely there is internal damage in the panel that you can't see. · It happens a lot with panels that are cracked as shown in your image. · You can't fix them, they have to be replaced. · Use the manual to view the procedure to remove the display panel and then once it is out, check on the back of the panel for the part number of the panel. · Search online for the part number, to find suppliers that suit you best. That way you'll be sure that you're getting the correct panel for the model.
