Damaged LCD panel, replacement options?

If the TFT matrix LCD panel glass is cracked, are there compatible replacements available?

Dell does not repair monitors or sell monitor internal components. We exchange them 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, or it was customer caused damage, 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.

Thank you for your reply. So only the design is on Dell's side. Manufacturing et al is outsourced far away. Feels sad to see big names caring more about profits and less about electronic waste created by shortening their product lifecycle.

Yes.

For example: for Dell U2415 monitor the factory installed display panel is 24.0" LM240WUA-SSA1 manufactured by  LG Display, which supports 1920(RGB)×1200 (WUXGA) display and has WLED backlight incorporated (no LED driver is present in the panel). The signal interface is LVDS (2 ch, 8-bit), a single 30-pins connector. There are other matching panels made by LG, Samsung, AUO and possibly others (abundantly available from 3rd party resellers), but the most important is that the mainboard LVDS connector signals mapping do match the LVDS panel specifications - as found in the panel datasheet.

To anybody seeking a way to replace the cracked screen, the options are:

  • either buy a new replacement LCD module (the display panel), or
  • buy a used display panel, or a used  monitor with similar size and resolution (checking first the monitor model specifications / resolution / backlight type / panel make, model, datasheet).

The replacement job will require disassembly, and one should carefully observe the steps in the video tutorials other users have created and posted on Internet. Or even better, leave it to a licensed repairer or somebody who has proven practical experience and knows how to avoid risk of electrical shock, ESD damage to the electronic components or the display panel - and can offer warranty for their work. Pay extra care with the cables connecting the mainboard to the display (LVDS, LED backlight and menu button board) as they can be easily damaged when removing the mainboard.

I am an IT guy who discovered repairing electronics by need - when looking to fix the hardware related problems I encountered with monitors, laptops, computers, networking, printing, audio-video and so.

I found that working with resources disposed for recycling is a very efficient way to learn, and solve many problems without big expenses. I agree that the cost of repair at specialized centres could bear a high cost - considering that fixing requires time, experience and somehow be lucrative. But younger generations tend to break technological barriers easier, and with the help of readily available information consumers can solve problems themselves when manufacturers can't.
