Black screen and 3 beeps

Haris HASSAN

8 beeps, display seen dead, 8 beeps seen repeated.

Please give a direction

Only 8 beeps....no display light, error code how to get?

Please give a solution.

Run the screen self-test - hold D through powerup. You should see a series of test screens (this runs independently of the mainboard).  If you do not, the screen is bad and will need to be replaced.

If you do see the test screens, check the cable that runs between the screen and mainboard for damage.  If it's not a touchscreen, and the cable is damaged, replace it;  if it is a touchscreen, the screen assembly will need to be replaced, as the cable doesn't separate from the assembly.

If the cable checks out OK, that leaves the GPU as the faulty part - meaning the mainboard needs replacement.

dell 8 beep, no display light-

done display test by pressing D key during on power button.

please give further direction.

Replace the mainboard.

I am asking if mother board is faulty....will is give 8 beep response, keyboard connection led glowing, mouse connection, if low battery give red LED, if bios battery removed 5 beep in first on and then go 8 beeps. Dear friend no way other than replacement motherboard?Need any checks in it? Please reply.

Run a screen self-test - hold D through powerup.  If you can get the self-test to run successfully but still get the eight beeps, the screen is OK;  the mainboard or the connecting cable is not.

If you get no response at all on the screen to the self-test, the screen is faulty.
