    OH MY GOSH! SAME HERE! It first started when I'd just slide the qwerty board, but now it's all the time. I get a red light, orange light, all colors! I'm glad to see this problem isn't because of something I did.

    same problem..i hate this phone..what a waste of time when the screen just blacks out ...restart restart restart till u suceed ..

    Started when typing SMS on Qwerty. Became worse over time. Sometimes I think that it has something to do with the battery, as the screen will blank when the phone demands a higher current, like when it rings. Replaced the battery but problem remains. It seems to get worse as the battery drops below 60%. The LED's indicating charging and fully charged are also sometimes messed up. It also happens that I find the backlight of the screen on with the screen off. This drains the battery big time. I suspect a hardware problem in the power curcuit or the lead to the screen as mentioned in other posts. As the phone is out of warranty, I'm hassitant to sent it in.

    Screen has been blanking out randomly for a few months. Over the last few days it has become unbearable rendering the phone all but useless.

    Have only had the phone 6 months.

After posting here on the 8th of March, I did convince myself that it has to be a hardware problem. As the phone is out of warranty, I got a technical guide of the net and began to disassemble the phone. My feeling was that the lead connecting the two parts of the phone or the lead to the screen had a bad connection, due to dust entering the phone. Long story short, I opened both connectors, cleaned and reassembled the phone. To my surprise, the phone booted up and worked.
The problem only resurfaced twice since then, when using the Qwery. It has improved a lot and I believe that dust is the culprit. Hope this helps. Thomas

What can i do about my phone's screen being black when its turned on?

When your screen is cracked you can assume it is defect. If it a new phone, you could visit a phone repair shop and ask what it will cost to repair this. If you have a insurance first ask the insurance company how to solve. If you have to pay yourself, decide in the shop if you give it for repair or you buy a new one.

I do not know what is wrong with my HTC S710. The screen go blank at intervals. what can I do to fix this.


The reason your phone goes blank at intervals is because there is a problem with the phone.

First, flash the phone with the appropriate software and cable, then you open up the phone with the appropriate screwdrivers and check if the screen connector also known as the flex is properly seated on the main board. Also check if the flex is damaged so you will be able to replace the flex with a new one.

Having done this, your phone will be in good condition once again.

Take care and good luck

Blank screen: screen not showing any data

All nokia mobiles operating on Symbian operating system may sometimes hang resulting in a blank screen, if it has some virus infection or overloaded with lot of mutiple simultaneous running applications. It may also be caused due to some incompactible mobile applications.
Solution: Remove the memory card and reset your mobile phone by removing the battery and installing it again.
If your mobile started up, then goto Menu -> settings -> restore factory settings.
If problem still exists then better flash the phone memory (just like reinstallation of phone firmware) by giving to to a nokia service center.
I hope this is helpfull to you

CNet reviews gives it an 8/10 but the users on the site only give it a 5.5/10.
There's a known sound flaw with this phone as well. Good idea that you asked.
