I would get it. If the LCD is the problem, the display could be disassembled to find out the make and model of the panel to see how much a replacement costs.

While I haven't replaced a panel in an LCD display lately, I have done many laptop panels. The last one I did cost between $150-170 for a 17" widescreen panel.

The only LCD display panel I replaced was on an older HP 17" model. I used a panel from one found in the hallway at work to replace one that had water damage. Except for the housing, it was exactly like replacing a panel from a laptop.
