Dell does not have monitor repair service

Dell stand alone monitors do not have an accidental damage protection warranty.

Dell has never repaired monitors or sold monitor internal components. We exchange the monitor while still inside the purchased warranty period.

* If you purchased the still inside warranty period monitor directly from Dell, read this
* If you did not purchase the still inside warranty period monitor directly from Dell, you need to first fill out the monitor Service Tag number Ownership Transfer form

The above exchange policy does not apply in the cases of customer caused damage, like an accidental scratching of the LCD screen, if you dropped the monitor off of the desk, or damaged the monitor while moving it.

Once outside of the purchased warranty period, you would have to seek a local Monitor/TV repair center to see if they can disassemble the monitor and diagnose the defective internal component. Then look for the internal component on 3rd party sites. Note, the cost of diagnosis and repair might outweigh the current used market value of the monitor.
