I have nokia 5800 XM for last 8 months, it has been going so gr8 until the last time in december 2009. i accidently dropped it in a resturaunt. My fone's display light has been messed up. It used to turn brighter when i unlock the keypad or there comes a call on the fone. But its messed up now. Neither does the display light go brighter when i unlock the keypad nor the light turns on when there comes a call on the fone and basically i cant see anything until i attends the call.
Please help me solve this problem!
Wait, I didn't quite get you... Can it go brighter when receiving a call, or not? If yes, you might try a hard reset(*#7370#, then default code is 12345), or you can reinstall your firmware, see if it helps. Try checking the light sensor in Settings>Phone>Display, make it the brightest, or the least bright, to see whether it's working, before doing the hard reset and FW reinstall.
If not working, well the only thing you can do is go to Nokia Care Centre, or use your warranty, since the phone is 8 months old.
i already did hard reset before throwing this question. And how to get the firmware reinstallation.? I think the problem is with light sensor. It turns brighter on reciving a call bt doesnt go brighter when i unlock the keypad, which it used to do before the accident. I believe its the problem of the light sensor. Do u know where is its light sensor located exactly. becz i m confused whter the one i m checking on, is a light sensor or proximity sensor.
1. Reinstallation of firmware can be done by using Nokia Software Updater via USB cable at any point by end-users.
2. The problem ure facing is only after the device dropped accidently, I advise u to consult Nokia Customer Care centre to get it rectified since hardware issues are not fixable by end-users and touching those internal components voids warranty.
You better visit a service point, unless the reinstall works of course.
If I were you I wouldn't bother disassembling my phone, since the warranty goes down at the very moment you do this.
