How can I fix a garbled e-ink screen?
I have a Samsung ereader E60 bought in the UK which uses e-ink for display. Afte carrying it around for a day in jacket pocket (soft down jacket) I noticed the screen was garbled and though the unit was powering on (a blue LED comes on) and parts of the screen flashed (the whole screen normally flashed 4 times while powering on) the display was bands of grey. The position of the bands have been static, but the grayscale within the bands change over time, and varied from reboot to reboot. Sometimes part of a band dispays some characters and sometimes not. The characters are from file names of documents in the device memory, and I have chekced this through USB.
My feeling is that either the display is malfunctioning or the display addressing hardware or software. The bands tend to lead me towards the former explanation. I have located the Samsung service manual for this product but its somewhat cryptic (I guess its not for Samsung engineers, as they are familiar with the board and wiring nomenclatures). I am technically knowledgable enought o take apart the device, but would really appreciate guidance in isolating the problem. Thanks
Es esta una buena pregunta?
