IMPORTANT NOTE
These replacement costs are "service centre" costs for full display panel, market prices are much lower depending on the quality and condition (new or used) of replacement parts. This is just a general info, please re confirm the latest prices while making a final decision, as prices vary from time to time. Most of the times, only front glass replacement is required which is much cheaper than full display panel.
