I have sony KDL32CX520 model it happen to turn into blank scrren while watching tv but the sound works?whats the problem??


What do you mean by this blank screen. A screen with back light only? A screen without any back light [dark screen]? Provide more details please. If you wish to get details about these type of faults to Sony LCD TVs, check this link.

Sony Bravia - no picture, no sound. Just a blank screen. We were watching a show and the screen went blank and no sound.


First thing to try: unplug from the wall; count to ten; plug back in; try again

Second thing to try: unplug from the wall; count to 10,000 (or wait 10 minutes or so); plug back in; try again

#1 worked for me when it would power on with no video, no sound, just small green light + white logo

When i turn the notebook on i can see nothing blank black screen


Sounds like one of two issues,

1. You have the internal display turned off. When you turn the laptop on you should hear a single beep. Do you see the Sony Logo during bootup? Have you tried to turn the display back on? Try pressing the Fn+F7, or Fn+F8, key combination. There are only three modes and these key combinations allow you to cycle through these modes. Either the Primary Screen is on, or the External Screen is on, or both are on.

2. You may have a bad video card or the screen is dead. When you power up the laptop, can you see a glow, but the screen is black? Can you see the Bootup Screen with the Sony Logo, but barely? Have you tried to connect an external monitor to the laptop to see if the video card is working? If you get video to the external monitor, the video card is working. If you don't, then the video card may be bad. If you are getting video on the external monitor, try using the key combinations listed above and try to cycle through your Internal/External display modes.If nothing shows up on the laptop display then the LCD screen may be bad. It could be the back light. Those are internal to the LCD. That means you will have to replace the entire LCD display on the laptop.

Hope that helps.

Sound like you may have a bad board or firmware. First thing to try is to go to sonyericsson.com and see if there is a firmware update online. If you can get it to update that may fix your phone. hope this helps

Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.
