Question about Sharp Aquos LC-42D62U 42 in. LCD HDTV
My 4 year old let go of his Wii controller and it hit dead center of the TV, clearly breaking whatever is behind the screen such that there are jagged lines emanating from the "break." Is this now simply a junker or is there a (economical) fix. Thanks.
An LCD TV, from front to back, consists of these layers:
protective film - <1mm thick
liquid crystal cells - <1mm thick
charge screen - <1mm thick
backlight panel - 5-10mm thick
metal heat spreader - 2-5cm thick
controller board - 1mm thick
Your son most likely damaged the liquid crystal cells...
Unfortunately unlike normal TVs these are precision assembled, and there isn't much you can do to fix it.
It is possible to replace the screen, but it involves replacing the entire unit, from protective screen right to controller board. In other words, almost everything except the plastic case.
Unfortunately I think the tv is busted permanently, and it will cost more to repair than to replace.
