Question about Sharp Televison & Video
Sharp Aquos LC-52D64U about 16 months old. When I turned it on last night it had plus-sign type dotted lines all across the screen. Same on all channels. Other TVs in the house were fine. Re-booted cable box and checked inputs. Still have the lines. Please help!
Thanks for using FixYa. To start with check all the cables at the back, you can also leave it unplugged for 2-4hrs. to see if that makes any difference. However, from what you have described it seems that you might have a backlight and/or an inverter board issue with this TV set. It could also be due to the inverter circuits for the backlights. The inverter is the power supply source for the backlights. There could also be a screen driver problem; if it is then you have to change the entire inverter board. All this is only recommended if you have some kind of expertise for checking the internal circuitry of the TV as these units have high voltages running even when the set is switched off. The cost to change the inverter board including labor would be around $250, if you get this done by a professional. Please do accept the solution if the issue is resolved or post a comment for further assistance.
