If the screen does not give any indication of being powered on, like some difference in color of the screen or momentry snow etc, then the power supply unit is not sending power to the circuit beyond. If there is sound then the display IC may be faulty. If there was sound you would have mentioned it. So, I presume that there is no power beyond the power supply unit. Check and replace it.

I have a SONY KF-WE50 rear projection tv, a few weeks ago it started to turn the pic and sound off while the green light was flashing around 30 times. After the light finished flashing both the picture and...


the green is the reboot process and is normal.
the red light is an error code indicator.
count the blinks of the red light...it cant be 30 times (I think)
it will blink a sequence, pause, then do it again for a total of three times.
count carefully, it gives you three chances to catch the number it is blinking.

Continuous alternating one green and three flashing red battery


note.gif NOTE: Battery operating time (the time the battery can hold a charge) decreases over time. Depending on how often the battery is used and the conditions under which it is used, you may need to purchase a new battery during the life of your computer. Check the battery status light — If the battery status light flashes orange or is a steady orange the battery charge is low or depleted. Connect the computer to an electrical outlet.
If the battery status light flashes green and orange, the battery is too hot to charge. Shut down the computer, disconnect the computer from the electrical outlet, and then let the battery and computer cool to room temperature.
If the battery status light rapidly flashes orange, the battery may be defective. Contact Dell _I found this on : http://support.dell.com/support/edocs/systems/latd820/en/ug/index.htm Hope this helps and good luck. if i "fixed ya" please rate me. thanks-jmattes

Flashing device status light


Ok the lightning bolt is your power indicator: solid green-charging, Flashing green-fully charged, flashing red-low battery, flashing red three times the once green-bad battery. the "trash can" looking one is your hard drive activity indicator it will flash while your hard drive is reading and writing.

Three red lights


Three lights flash red on the Ring of Light (RoL) on the front of your Xbox 360 console. The upper-right quadrant light is the only light that does not flash red. CAUSE: The three flashing red lights may indicate that there is a hardware problem with your Xbox 360 console. MORE INFORMATION: If you are experiencing this problem, you can submit a console-repair request online. However, before you submit your request, first try the following two steps to verify the problem: 1. When you turn on the console, look at the light on the power supply. The power supply light should illuminate green even if the three lights on the Ring of Light flash red. If the power supply light is not green, please follow the steps in one of the following Microsoft Knowledge Base articles: 906101 (http://support.microsoft.com/kb/906101/) Troubleshooting your Xbox 360 Power Supply when the light is red 906102 (http://support.microsoft.com/kb/906102/) Troubleshooting your Xbox 360 Power Supply when the light is orange 906103 (http://support.microsoft.com/kb/906103/) Troubleshooting your Xbox 360 Power Supply when the light is not illuminated 2. Turn off the console. Wait 10 seconds, and then turn on the console again to see whether the problem re-occurs.If your console continues to display three flashing red lights, your console may have to be repaired. If none of these help, pease contact Xbox support at http://xbox.agent.asahost.com/ to talk to a live agent.

Red Light Flashing 6 times


When the lamp fails in this unit, often the thermal fuse opens. The error code is 6 blinks. To replace this part requires a great deal of deal of disassembly.
