LCD backlight "stagelighting" & intermittent image garbling + whine
Hello all - any help very much appreciated. Have some ever-present "stagelight" or "spotlight" effect at the bottom of my screen, as seen in the first picture. Also, as seen in the second, the display at time locks at fades into garbled lines.
It works perfectly on external monitor, also the second image is intermittent, and moving the screen or applying pressure to the bezel helps resolve it.
In addition, at anything less than full brightness there's a quiet high-pitched [incredibly annoying!] "whine" that gets quieter as brightness is lowered.
Here's the relevant area on my logic board... looks ok: http://i.imgur.com/f5RRNoP.jpg
This a problem with the LCD itself or just the LVDS cable possibly? Works perfectly when connected to an external monitor.
Is this a good question?
