I have a Viewsonics VP920 that has been dropped. No sign of internal damage. It powers up and then goes to sleep after 10 secs. Power LED goes from Green to Orange. No components are hot. Screen is ok and displays a no signal message. If I cycle the power, it still runs for 10 seconds. It seems like the sleep timer period is wrong.
I have removed the back cover, C805 is 150 volts from a 110VAC supply. Tks for your thoughts!

there is a component that is failing as it heats up, when it goes off it cools and so goes on again and so forth. the more it does this the more likely that more things will be damaged so best to leave it unplugged until repaired.
Seagate manufactures both internal and external hard drives, and their sleep modes can be managed in different ways. The hard drive is one of the top energy consumers among computer-hardware components, and Windows operating systems support options to reduce power consumption. Internal hard drives are typically turned off and stop spinning ("sleep" mode) after a certain period of system inactivity. However, the system usually takes longer to come back when the hard drive's sleep mode is activated. Furthermore, turning off hard drives may result in failure of some constantly running applications. Windows includes options to turn off sleep modes for internal hard drives, and external hard drives can be managed using a utility program.
Log in to an administrator account and click the "Start" button in the lower left corner of the screen. Click "Control Panel" and then "Systems and Maintenance." b> Click on "Power Options." Open "Change plan settings" under your current power plan. Note "Radio button" is selected for the current plan. Click "Change advanced power settings." Expand the entry "hard drive" by clicking on the "+" sign. Click on "+" to expand the entry "Turn off hard disk after." Select "Never" for this option and click "OK." b> In Windows XP Log in to an administrator account and click the "Start" button in the lower left corner of the screen. Click "Control Panel" and switch to the "Category" view on the left panel. Then click on "Performance and Maintenance." Click on "Performance and Maintenance" and open "Power Options." The select the tab "Power Schemes." Using drop-down list, set the option "Never" for "Turn off hard drives." Click "OK." b> Using "NoSleepHD" for External Hard Drives b> Click on the "NoSleepHD program" link in Resources. Click "I Agree" and save the program (as a zip file) on your computer. Open a folder where you have saved the file using Windows Explorer. Right-click on the zip file and select "Extract All." Then click "Extract" to get the program file "NoSleepHD v1.0.exe." Double-click on the program (.exe) file to execute NoSleepHD. Click "Select External Hard Drive" in the Program menu and choose your Seagate external hard drive. Choose "10 minutes" under the option "Write File every" and click "Start NoSleep Mode." The program will write an empty string every 10 minutes to the Seagate hard drive and prevent it from going into sleep mode. Hope this helps.
Issue would seem to be in the power supply for the set but could be elsewhere---first place to look if you are able is the power board--power cord goes directly to that. If able look for any puffed up caps or any physical signs of damage parts on that board, there may or may not be signs to see but worth looking at first.
Here are photos of bad filter caps from mild to extremely puffed ones:
You might want to check the sleep timer, it may be ON and set for 10 min. Go to the OnScreen Menu to get to this setting. Also, you could be nearing the end of your "relationship". There may be an internal board problem that may mean a trip to the TV doctor.
THE GOAL HEAR IS TO DETERMINE IF THE INSTALLATION IS CAUSING YOUR PROTECTION FAULT OR IS IT THE RECEIVER ITSELF HAVING INTERNAL DAMAGE. REMOVE THE RCA INPUTS AND DISCONNECT THE SPEAKERS, THEN POWER THE RECEIVER UP WITH THIS NO INPUT, NO SPEAKER LOAD CONDITION. IF IT STILL GOES INTO PROTECTION, THEN THE RECEIVER WILL NEED TO BE SERVICED, AS YOU HAVE TOTALLY SIMULATED A BENCHED CONDITION THAT IS TOTALLY INDEPENDENT OF YOUR INSTALLATION. MOST TIMES, THE RECEIVE WILL GO INTO PROTECTION WHEN IT SEES AN EXCESSIVE LOAD WHEN TURNING UP THE VOLUME, WHICH IS USUALLY CAUSED BY TOO MANY SPEAKERS OR DAMAGED SPEAKERS, BUT IF NO SPEAKERS CONNECTED, THEN IT IS USUALLY BECAUSE THE RECEIVER SEES AN EXCESSIVE LOAD DUE TO ITS OUTPUT SECTION BEING DAMAGED. IN ANY CASE, ONCE REPAIRED, YOU MUST CHECK YOUR SPEAKERS FOR BURNED VOICE-COILS, WHICH WILL IMPOSE AN EXCESSIVE LOAD TO THE AMPLIFIER AND CAN CAUSE IT TO FAIL AGAIN. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V
This is a feature of windows it's not a problem. Your settings can be changed in:
Control Panel>Mobile PC>Power Options
On the left side of the screen you will see "Change when the computer sleeps" click that, then click Advanced.
You will see the wireless power options in this panel.
If you need I can put some pics on my site to help walk you through it or if you have a different OS let me know XP is much the same.
Is your laptop's Operating System Vista? Also, does the laptop completely power off or just go to sleep and nothing you do (touchpad/pressing keys) brings it out of sleep?
If it still is powered on, but won't come out of stand by, or sleep mode try this:
Go to Control Panel, and on the left hand side click Classic View then double click the icon for Power Options.
There will be a few options under Preferred Plans and one is selected (Filled in dot)
Under the Power Plan that is selected, click Change Plan Settings and on the next screen, click Change Advanced Power Settings.
You will have a new window that opens up with a bunch of categories with little boxes with + signs. Click the + Sign box beside sleep to open op the menu. In the options under sleep, change HYBRID sleep and HIBERNATE to NEVER. Especially the Hybrid sleep as this was a problem I found with Vista. It sounds like the computer is going into the Hybrid/Hibernation and not comping out from it unless you power off the computer and turn it back on
Also, click the + sign beside Hard Disk and make sure the option to "Turn off Hard Disks After" is also set to NEVER
