I have the same problem, white screen, i can still make phone calls etc etc so the phone works but there is no screen. I followed the instruction, took everything apart but cant see the ‘4 solder points’ where to attach the electrical tape. Is is on the clip that attaches to the motherboard or the bit that attaches to the screen.

Many Thanks

Tony

Here’s another update on this issue. It worked for a bit, but then had the same screen after a couple of days. I tried opening it up and playing with the display connector, putting it back together, a few times and it came back up for two days, and now it is dead again.

I even tried to put take on the solder points below the audio port, but it did not help or make things worse.

I am out of warranty and out of ideas at this point, and would greatly appreciate suggestions.

Thank you.

That definitely brought it back to life.

I have been unscrewing the BB9000, pulling the board with the screen out, unplugging the screen connector and plugging it back, several times.

It worked a few times in the past, but would go out again. Then that stopped helping.

Putting the insulating tape on the solder points and putting it back has revived it. I hope that it stays put this time.

Thanks for your help,

The problem: A completely, with an emphasis on completely, blank white screen. Occasionally, the phone appears slightly fuzzy, or glitchy. Also, the phone occasionally appears completely normal. The phone, in my case, worked fine despite the screen problems.

The fix: I found a thread about someone claiming that the four solder points behind the mini usb port somehow created a short behind the screen. The guide said to, first, completely disassemble your blackberry (sorry I don’t have the guide here…could look for it today and send it to anyone that requests) After disassembled down to being able to see the green motherboard with the small screen attached, slightly and carefully peel the left side of the screen (the side that contains the mini usb port) a bit upwards until you can see the four solder points. For the laymen, these solder points are simply 4 grayish/silver spots. While taking care to not lift the screen excessively and leaving the majority still attached to the motherboard, take a piece of electrical tape, or any insulator and carefully put it over those four solder points.

Then, push screen back into position, reassemble, and test.

Please let me know if this works for you. My problem was solved instantly.

As for a second major problem of blackberry owners: if your phone will not sync with your computer and you have a bad mini usb port on your blackberry, it is probably because of the mini usb female port of your phone. A replacement of the port is the only solution I know of for this problem

As for a white screen with an hourglass: I think this is probably going to, usually, be a software problem and requires a reload of the operating system using your blackberry software on cd, or software directly from blackberry.com
