You need to update the software/firmware of your phone. Doing this usually solves the problem. if it doesn't then you need a new screen.

Failing Inverter An inverter, typically found inside a laptop computer, consists of a small board, which has impregnated electronic circuits stamped on it. Inverters look like thin boards about the of two sticks of chewing gum. The inverter and its bulb control the intensity of the liquid crystal display, which lights the screen monitor. The computer can control the output voltage of the inverter and either lighten or darken the screen. A special type of inverter can adjust the brightness of the screen by using an internal sensor to judge the room brightness, and then adjust the screen accordingly. Failing inverters give off some specific warning signs, which can be recognized by observing different screen characteristics.

Short Intermittent Display Upon turning on the laptop, the screen flashes on in the normal mode for a short period and then blinks to black. A very faint image appears in a dark background, which will be very hard to see almost invisible. After shutting off the laptop and restarting, the same mode occurs, where the screen appears normal for a few seconds then fades to black. This condition points to a failed inverter. To confirm this, plug in an operational external monitor; if the external monitor functions, the inverter has failed. b> Total Blackout with Ghost image b> The laptop turns on, as indicated by the power supply button, but the screen comes up black. The screen comes up black after restart. You might be able to detect a very dim or ghost-like image on the monitor. When you plug in a known functioning external monitor, the external monitor operates normally. This mode of display indicates a failed inverter. b> Long Term Periodic Operation b> With this failure mode, the laptop screen illuminates normally upon start-up and remains that way after several minutes, hours or even days, until it goes very dark again. Brightness controls or restoration attempts do not work. Most often, the screen will function normally with a computer restart, but will eventually return to black. Faint ghost images might appear, as seen in the total blackout mode. b> Dark With Color Variation b> Upon computer start-up, the monitor shows black or dark gray, accompanied by very faint images. The screen might have an intermittent color change, or remain on with a non-standard color variation, like pink or red. b> Auto Control Switch b> If the screen appears black, with no faint or ghost images, look for the lid switch near the back hinge. The switch, when depressed with a closed lid, shuts off the computer and monitor functions. Sometimes the switch becomes stuck in the closed position, disallowing the computer and monitor to turn on when opened. Pushing the switch manually several times can often free it up. If the switch tab has broken or jammed inside the case, it needs replacing. b> Loose Connection In this mode, the display looks normal upon start-up, but tapping the side case of the computer turns the screen black. More tapping results in the screen functioning normally then cutting out again. This condition points to a loose wire connection from the inverter to the LCD backlight lamp, or the video cable. The connectors can be accessed by removing the monitor bezel screws and pulling the plastic retainer off. Both connectors can be cleaned and refitted.

Am using verizon 9530 unlocked. phone is working, the backlight is active on buttons...!! the screen is not active.. i could answer / receive calls.. can hear the notifications of receiving emails /...


When you get your blackberry screen blackout? After your blackberry 9530 unlocked or a few days after you unlocked your phone? Did you get my point? If you get that blackout screen after blackberry unlocked process try to reset your phone to default factory setting and if still not working try to reinstall your blackberry os, but if you get that blackout screen a few days after you unlock your phone looks like your screen already broken and you need to replace it in your nearest local mobile repair shop.

When monitor power button is pressed, a small white image appears and alternates briefly between an alalog and digital icon in black then the screen goes blank, no color.


My issue is similar.. however after trying a couple of times it will work. (yes everything is plugged in) It will function for a good 10 minutes before just powering off (blackout) screen.
If you attempt to turn it on after it blacking out, the blue led for the power button will blink a couple of times and it will remain off.
However if you wait 5-10 minutes and turn it back on, it will repeat itself...

I have it hooked up to a radeon X1650 graphics controller as a secondary digital controller, and its hooked up by VGA cable.

I also have two other displays besides this one (one primary and extended that dont have any issues whatsoever.. they continue to function while the syncmaster 193p takes its time snoozing.... please help.

SCREEN WON,T STAY LIT UNLESS I TOUCH IT


You are simply in blackout mode. This is so at night you aren't blinded by the glow of a screen. Here are instructions right from the manual to turn on or off.

Blackout Mode On and Off
When Blackout mode is turned on, the monitor display will turn off to
reduce power consumption.
This additional power enhances the sound quality.
1 Touch [VISUAL] on the main source screen.
The VISUAL selection screen is displayed.
2 Touch [OFF].
The backlit-display portion goes out.
3 Touch [OFF] again to cancel the display backlight.
To make the setting, set to “Setting the VISUAL Touch Button” (page
34).
If any button on the unit is pressed during Blackout mode, the
function will be displayed for 5 seconds to show the operation before
returning to Blackout mode.
While the backlighting is turned off, the function indicator

TyTN II - Keep the phone screen alice during a call


Hi there,
Received the following reponse very promptly from HTC Support
---Quote---
This is actually a function of the phone and not a fault. It was designed so that when you were on a call and had the phone against your ear that you didn't accidently tap on the screen and open functions or end the call etc. If you wish to access the touchscreen while on the phone you can press the power button on the side of the phone to turn the screen back on. I have attached a 3rd Party Application that allows the screen to stay on while you are on a call. Follow the below steps to install the program. Attached is a patch for the TyTN II screen blackout issue.
This is not an official fix.
  1. Copy the KaiserTweak.zip folder to your pc's desktop.
  2. Connect you device to the pc via ActiveSync.
  3. Use the Explore function in Active Sync to copy the KaiserTweak.zip folder to the windows directory on your TYTN II.
  4. Disconnect your TYTN II from the pc.
  5. Open up file explorer on your TYTN II and go to the windows directory
  6. Unzip the folder to the windows directory on the TYTN II
  7. Run the Kaiser Tweak.exe to install the patch.
  8. Adopt the recommended configs, not the default.
  9. Soft reset the TYTN II by pressing the stylus into the little circle hole on the bottom of the handset.
If it doesn't work first time hard reset and try again. ---End Quote --- Thanks to the FixYa guys for thier intererst in this topic and problem Cheers Corpcc
