Question about Dell Inspiron 1420 Notebook
Hello I'm repairing a dell inspiron 1420 that black screen appears when you start by connecting external monitor provides image. I did a test with dell dianostico and get this message: lcd inverter lamp failure Unable to turn off . error code 2000-0326. what is the solution to change the inverter or full screen
The diagnostic Error is a False positive you can ignore the diag error as the LCD is functional. If the battery is not recognized in the BIOS or you get an warning the AC adapter is not recognized, then you may have either a damaged AC adapter sensing pin (Fine wire in middle of ac adapter connection to Laptop) or a problem with the charging unit on the motherboard.
If the sensing pin is damaged or the ac adpater is not sending the right signal to the system, the battery charger will not work. SO if you have another Dell D series AC adapter, you can try it 1st. If the battery is 18 mos to 2 years old, you might see if it is IDs in BIOS and if it indicates battery state. Also the battery should have a test button and 5 LEDs on it. If the 1st 3rd and 5th LED flash the battery is bad. ANy any come on solid, then it is a % of charge, each LED = 20%
If you end up replacing hardware, then it will most likely be in this order:
AC Adapter, Battery, Motherboard

Check out http://www.ccfldirect.com. they have a wide variety of inverters and backlight tubes for LCD panels and laptops. I'd change out the tubes at the same time you replace the inverter. The cost is minimal, and will increase the likelihood that you'll be successful

the interal graphics adaptor is making trouble, to find aóut if it just with your screen, hook up another external monitor and boot up.
Still the problem?
then you wil have to (let) the graphics card (be) replace(d), definitely.
