Hello, I have a problem with my H/packard L/top, I struggle to get a clear screen during use & tap prod move the screen/lid to various angles. It is always clear when the lid is open about 50mm. as I type this the lid is fully open & it,s a struggle (heaps of squiggly lines as in the early days of tv.) then all of a sudden the screen is perfect. I suspect it may be the screen interface to the k.board connecting somehow through the lid hinges. My comp. knowledge is zero & I wonder is it worth a shop repair as it may cheaply made by robots/ repaired expensively by humans, it,s 5 yr. old & a point to ponder.Anybody out there experienced/solved this,all sensible comments welcome.
