6500 slide display screen issues

Question

Hello, first post and first problem with my phone so far, i'm still trying to figure out whats wrong with it.
I bought my slide from a cell phone vendor in Singapore, and thankfully i have insurance so if anything is unfixable my insurance will take care of it, but i haven't looked into what id have to do to get that done since im here in the us.
My problem is this. Recently, my screen or display is starting to do some weird stuff. Sometimes the screen just goes all black, and i cant see anything on it, i can see that it is backlit, that there is at least power going there, but no picture, and sometimes, the normal image of the phone is seriously distorted, like someone switched the colors on a laptop display from 1 million to like 36 colors, not cool. While this is happening though, all the functions of the phone are operating, i can hear when i enter in numbers, and i can dial my voicemail, and im sure if i could remember the key sequence to say....play a mp3 i think i could do that as well. This seems to happen when i slide the phone out, but not always, sometimes the slide will be in, and it wont show anything, and then ill slide it out and nothing happens, so nothing concrete but this is happening. But it always consistently comes back at some point. sometimes ill just leave the phone slid in with the screen black, and eventually it will come back....
When i had first got my phone, something similar to this had happened, but never for longer than a few seconds. A couple of times after i had been using a bluetooth stereo headset, i had switched off the headset, and then later wanted to reconnect it, but the phone for some reason had it still listed in actively connected bluetooth devices. So i would cycle bluetooth off and then on again. After turning blue tooth off, the phones screen would blank, as if it was restarting, and then i would wait a second, and then the normal stuff like icons and network and all that stuff would come back, like it was thinking real hard or something.
I thought that it might be software related, i have some games on my phone, and maybe there were problems caused by them, or i thought it might be because i had been using a 6gb hcsd micro card in the phone. I had been using it in the phone for a while, with no issues whatsoever, but then this started happening, so i took it out and put in a 2gb micro sd card that i have as well.
I just finished installing the latest phone software, and i had done this once before, when a new version came out, so now i have the newest phone software available. Now....after i did this successfully, i examined the phone again, slid it in and out, and the screen went blank a few times, then came back a few times. I decided to shut off the power and then turn it back on, and it seems, as if this is not happening any longer, though i think pessimistically that it might happen again.
If anyone out there has experienced something similar or exactly like this, and has found a solution please let me know.
I'm worried that it is hardware related, or permanent damage to whatever counts as a phones bios or firmware, but i cannot be sure.
Any help or info is greatly appreciated,
Thanks,
Ian.

Hi all.
Thank you both for your input as far as my problem with the phone is concerned. I had done some reasearch on the problem, and due to the fact that i am in the United states, i decided to see if i could get the phone repaired here locally. I found a place that works specifically on nokia phones, and they looked at my phone and said that they thought that it needed a new flex cable and a new lcd screen.
I was unable to find parts that i could buy singularly from any vendor, although i was able to find parts for my phone at a website called http://www.tessco.com/
The people i brought the phone to said that my phone needed a new audiovisual flex assembly, and a new lcd screen, as tessco calls them here: look under flex assemblies. they do not sell lcd replacement screens apparently.
http://www.tessco.com/products/bmd/listItemsForSel​ectedCategory.do?bmdTypeId=007_26&mfgName=007_26_N​...
I could not buy my parts from tessco because they will only do batch orders of 125 or more for each part. So, i looked around on ebay, and found 2 auctions where i found an lcd screen, and an AV flex assembly for my phone.
here are the auction links
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1​&item=120217680995&ssPageName=STRK:MEWN:IT&ih=002
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1​&item=110206704806&ssPageName=STRK:MEWN:IT&ih=001
i purchased these two parts and the repair guys here locally said they looked good. They repaired my phone using them, and when it was done, apparently they said everything was fine.
Shortly thereafter, i was using my phone, and the same problem keeps on happening. The screen is still going black intermittently, and it is driving me insane.
What i am thinking is that something that i DIDNT replace is defective, but no one can seem to figure out what that is, or doesnt know.
If anyone can contribute some info to my problem, please help.
And thank you.
