Toshiba Satellite L655D Screen issue...at a loss

[Eric Richardson]

Ok...customer complains of screen "going out"...so I check it and it's doing a bunch of weird horizontal scrolling...but external display thru VGA seems fine.

No inverter since it's an LED and I'm sure the screen is bad so I order a replacement from ScreenTek...swap the screen out and now...even worse...barely a flicker after replacement...but it looks like a refurb...so I send it back for another and in the interim - get a replacement video cable as well. Swap out the cable...same issue...replacement screen from ScreenTek - almost good...but there's still shadowing on the icons and if i do anything like open MS Word...the display just freaks out... What the ****?

Could the GPU actually work to an external display but be completely hosed for internal? I haven't seen that before...

Thanks,
Eric

Hi

Seen this before (see my sig)

You are NOT putting in an IDENTICAL screen.... numbers and letters on white sticker on back of the screen MUST BE IDENTICAL, down to the last number/letter...

All the best Brett
