Problem:no vision,when flowing voltages all parts.no interception on path,no breaks on path.all condutor well .passing voltages together.but no vision on screen.first examine the EC program and screen parts are good. solution:once heating the processer gently,around.the processer section if its inactive become active.active and transfer the signals each section.got the vision .
problem: visual is not clear, its dim and bluring .how to restore this. to get working condition.not repair itself.place a new .see the visual clearly and brightly.
problem:no vision and its down in a sec, if press the power button.when inspecting the the voltages are flow well.but not functioning.once reinstall the hardware programme .its performing,visuling. but unexpectly ,its back at condition. solution: all semicondutor are well .no harm,no weak but its occuring.we ultimate to heat the processer part and graphics part and …
