You need to restore the phone to the factory defaults. If this doesn't work, you'd have to bring your phone to someone that can update the phone's firmware.

Sony KDL-40XBR2 - powers on, backlight is on, no pic, turn it off and back on, same for 10 to 15 seconds, then TV does power off/back on by itself...most of the time picture then shows up.


Depending on your enegy, on home, if is variable or steady 110V
you can check these on your TV, but safety first, or seek a qualify tech:
1) bad capacitor for power module **
2) bad inverter board or capacitors burn.

good luck!

MY HP LED HD 23" screen goes black for few seconds and then goes back up again.


This is most likely the power inverter. It's a relatively small part but if it's not supplying power to the backlight, you won't see anything.
It needs to be replaced.

RE:monitor goes black


Monitor going black after a few seconds can be causd by a faulty power supply or inverter. Some monitors have both as one unit.
Sometimes it is basic failed capacitors, After that then I would look at transistors.
The average monitor from 17 to 20 and sometimes the 22s have usually 4 bulbs in them. One bad bulb will also cause the inverter to not fire up.
Bad bulbs usually show pinkish tint, or flickering or are dark at center top or bottom of the display.
