My monitor started showing only horizontal color lines and i don't see anything else on the screen. So, i had to connect to a monitor through HDMI and run diagnostic tests. On running BIST, i got an error with code 2000-0334 with validation # 3211 and msg: Video - User reported the patterns were not displayed.
Can you please advice on what steps needs to be taken to resolve display issues? I am using Dell INSPIRION N5050
Do you see these lines every time you turn on the system? Is there any physical damage / liquid spillage on the system? Does the system overheat?
As the HDMI is working fine, I would suspect the LCD at this point, as the graphics card seems to be functional.
Run the LCD bist - Turn off the system and press and hold the "D" key + power button to turn on the system and it should run the LCD built in self test - see this link for more info - http://dell.to/1SkXNrG
If not, the LCD cable and the LCD assembly needs to be replaced.
If the system is under warranty, write me a private conversation with the service tag and your contact details(Name and Email). If there is no warranty, then you could contact our team to get a quote for a paid service call - http://dell.to/1vnT6CQ
