Blank screen When I power on the system, nothing is displayed on the screen. Please help me.

If you verify it has power to it and it still doesn't work, you will need to take it in for service.

You must reset your PS3 in order to accept the new TV configuration.

If the video output settings on the PLAYSTATION3 do not match those of the cable or TV in use, there may be no picture. If the screen goes blank, turn off the system.

Then, with only the PLAYSTATION3 and the TV connected, touch the system's power button for more than 5 seconds to turn the system back on. The video output settings will automatically be reset to the standard resolution.

Hope this helps please remember to rate my response, thanks!

Have you tried starting from the system disks that came with the computer? Put the disk into the computer and start up holding the C key down.

First, make sure it is fully charged and plugged in.
Look at the power indicator:
• If it is not lit, no power is being supplied to the computer. Check the
following:
• If you are using on the battery, it may be low and unable to power
the computer. Connect the AC adapter to recharge the battery pack.
• Make sure that the AC adapter is properly plugged into the computer
and to the power outlet.
• If it is lit, check the following:
• Is a non-bootable (non-system) disk in the external USB floppy drive?
Remove or replace it with a system disk and press <Ctrl> + <Alt> +
<Del> to restart the system.
Nothing appears on the screen.
The computer's power management system automatically blanks the screen to
save power. Press any key to turn the display back on.
If pressing a key does not turn the display back on, three things might be
the cause:
• The brightness level might be too low. Press <Fn> + <→> (increase) to
adjust the brightness level.
• The display device might be set to an external monitor. Press the display
toggle hotkey <Fn> + <F5> to toggle the display back to the computer.
• If the Sleep indicator is lit, the computer is in Sleep mode. Press and release
the power button to resume.

Your honeywell should have battery back up but the primary power for this is a 24 volt transformer located in the air handler probably in your attic. All these controls run on 24 volts

Make sure you set up your laptop to display to a second screen. Depending on your Operating system, go to your display properties and go to the settings tab. Then click on the second monitor and enable it.

on restart press f8 then safemode
do a virus scan
then a disk defrag
have you added anything new or changed the system
please let me know if this helped and don't forget to rate me
thanx

One of two things either the disply has gone out which is likely as it is a common failure for that thermostat or your heating unit is not sending control power. the older chronotherms were system (24volt ac) powered the new hardware/box store units are battery powered. Either way display should not be blank with fresh batteries. to get heat on remove the thermostat jumper or twist together the wire from the R terminal with the wire from the W terminal. note the color of each wire for later reference, heat up house disconnect wires from each other and go purchase a new thermostat

LOOKS LIKE A BURN SOLDER !! , open the monitor , check the PC BOARD around the transformer area , look for burn spot or cold solder , RE solder it , try again , hope this helps please rate solution and thanks AJ
