Can still hear tones from incoming call or text messages. Other than the display screen the phone is fully operational. Dm sees it perfectly, You can still do a blind-call out and receive calls. Only problem is i can only see a bright white screen. Many sites has been suggesting a solution such as this: Battery pull, wipe, reinstall 4.6, reinstall 5, backup and restore files, clean install, battery left out for 24 hours and installed a new battery but it doesn't fix the problem. Now, heres' a solution on how to fix a a Blackberry Bold 9700 with white screen problem. 1. Reassemble the Blackberry bold 9700, only do it unless the warranty period has already expired. Now, locate the highlighted components as shown on the image. These are the display filters. Works as electrostatic discharge (ESD) and electromagnetic Interference (EMI) filters, and once being damaged it will cause and result to a white screen, sometimes being garbled or saturated screen display.

Just like the one below that taken apart from the damaged Blackberry 9100 PCB board. Then in place it to your Blackberry bold 9700 display filters. Try replacing one by one then power it again to check, just repeat until all four filters being replace and get the screen display fix. That's it! all credits goes to Rievax_08 and GSM Solido for the repair tricks. Happy fixing hope this helps. |

Member: 1768224 Status: Offline Thanks Meter: 0 | HI .RoMoN. My BB9700 screen becomes white, but sometimes I can turn it back to normal from turning on screen lock button with several tapping to body. Not yet tested with other working LCD, so whether this fix works on my BB? |
