Screen problem Inspiron

Hi JessyN,

We will have to perform the ‘LCD BIST’ (Built in Self-test) on the computer. Please follow the steps mentioned below to run the “LCD BIST’.

1. Turn of the computer.
2. Press and hold down the ‘D’ key on the keyboard and press the Power button.
3. You will see different colors on the LCD screen. Please check if the issue reoccurs on the screen.

In addition, please connect the system to an external monitor and check if the issue reoccurs.

Hi Ravi

I've tried this but it doesn't work. When I try to turn on my laptop I heard 2 beeps after 30 seconds.

Do you have another idea

Thank you

I've tried this and I still hear the 2 beep. I think I have to try with another Ram. Is it expensive to replace mainboard ?

I forgot to tell that when I try the "D" key + turn on, I see the screen change between two "sort of black". I didn't see any color but just two shades of black. Does it mean something ?

Two beeps means no memory is detected.   Remove the battery and then then the base cover.  Remove and reinstall both memory modules and try again.  If you still hear the two beep code, try one module at a time in each socket until you find the bad module (replace) or the bad socket (replace the mainboard).

If reseating the memory as above doesn't help, the memory controller is likely bad and you'll need a replacement  mainboard.

Hi JessyN,

As informed by ejn63 2 Beeps on Dell Inspiron 1546 indicates Memory or Memory slot failure. You can try with a compatible new memory on the slot to figure out if it’s an issue with Memory or memory slot.
