Did drop my tab and there??s no video now, provably the LCD panel got busted. Is it really worth to go through the process of replacing it? If that is the case, any idea who carries the replacement unit? Please help.
Can somebody please send me a link where i could purchase the samsung galaxy tab 8.9 SGH-1057 battery. I order the wrong one on amazon for 10.1 still in plastic
Bill, I think your unknown chip 34LM85AM is a LVDS transmitter of DOESTEK. You can also find DTC34LM85A on web searching. I hope this tip can be helpful you to finish your report. ^^
Bill, I recently purchased a 10.1 Galaxy tablet (I'm thinking the devices are the same, except one is bigger) in Nov-2011, I am having to send it to Samsung for repair today. There are problems with the 'newton ring' affect under the glass of the display, this is an oily bubble that appears. (videos can be found on youtube relating to this problem) in the middle of the screen and you can push it around with your finger. Three weeks after purchase - device was not cheap (32GB, 4G enabled) - the bubble started small and was hardly noticeable at day 5, at day 15 it is about a 1/3 of the screen in the middle. I do not put a lot of stress on the touch surface, light pressure mostly with a conductive stylus. I'm curious if in your tear downs you have discovered an oily film layer inside of the devices that could be causing this problem? Various people have commented that this is caused by imperfections in the gorilla glass against the touch screen pick up points that detects finger/conductive stylus moments, but I wonder if this is speculation on their part. To be clear, I really like the device, I own multiple Samsung products and I'm looking forward to getting the tablet back.
Bill I am a professor at a community college and was wondering if it would be possible to get in a folder, zip or links to all of the media you have cracked open. Really only interested in devices lass than five years old and not all of the neat old systems you have opened. We would like to start a class here in Supporting and Maintaining Mobile Media. I have looked at many of the devices you have opened and this along with the need for a course like this has led me to you for any availalble resources. Any help from you or your staff would really be appreciated. Thanks Fred Moore Director / Professor Grayson County College Denison,Tx
Fred, I hope your new class is successful. As an adjunct faculty member myself, I'd be glad to help in any way I can. I'm afraid I don't have a list of URLs to all the cracking open/teardown galleries I've done over the years. But using TechRepublic's site search, you should be able to manually create a list (as a text document, spreadsheet, etc.) You could then share that list with your students.
