TV's have a circuit that monitors the high voltage and shuts down the set if it senses something amiss.
On projection types, figure on just replacing the entire board that has the flyback transformer on it.
Hope ya fix it!

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!

II get sound for about 15 sec. but no picture and then shuts off


kp57ws50_57_in_rear_projection_hd_228277.jpg Problem with Sony KP-57WS520 57 in. Rear Projection

This model is really prone to one problem in particular--screen even briefly comes up bright red, green or blue and set shuts down.

15 seconds from turn on front power light should blink as set checks several things internally---if something wrong it does not let picture show.

Usually after shut down or failure power light will blink a sequence of blinks but not always depending on problem.

Did you see the screen at all go red, green, or blue before?

the more you tell me the better I can help

Wait 10 minutes
Plug it back in
Turn it on from the remote
Press reset if it does not show up
Hold the power button to shut it off
Turn it on once more.
If this not help may your Wii need service.

My Philips plasma only shows half the screen. The other half is just blacked out.


This model has PiP (Picture In Picture), find the button on the remote or check manual, this mode is most likely turned on and is being shared with one of the AV channels, or try turning on a plugged in SCART device to see if this picture shows on the other half of screen.

Flashing, slow startup, and finally, just snow


Try resoldering the pcb, especially the heat producing components on the pcb, do it with the crt base card too, I guess this will fix this up. Good luck.

Base on the information given to me.

I think your computer is on sleeping mode.

first thing check if the video cable is not loose connecting the pc.

because what would happend, if it is loos it would turn on and off at times.

The other thing you can do.

right click on the desktop.
go to properties
go to screen saver
click on power

adjust the time you want your monitor to shut off.

Monitor only stays on for 3 seconds


There is probably a bad capacitor within the monitor that will not allow the picture to "hold" in the on configuration. This will need to be replaced. You can send it back to Phillips, or 17" monitors are pretty cheap these days. I would suggest a Samsung or BenQ. They both carry 3yr warranties.
