it is possible,just because you are connected wirelessly,doesn't mean that you are connected to the internet,you ARE ONLY CONNECTED TO YOUR MODEM,unplug your modem from the internet and power for 30 seconds then plug in the internet wire then power and let it reboot,then see how the connection is.if you have more things connected to the modem,either wirelessly(like laptop) or wired(like xbox or tv),they will use your bandwidth which will cause connection errors on a tablet
Put the Mac install disk back in. Try pressing command-option-escape to force quit. If nothing happens, then press command-control-power to force a restart. If that doesn't work, press and hold the power button for five seconds or so until the computer shuts down. Power up the computer again, and hold the option key so you can select the instal disc for startup. Run Disk Utility again. Sometimes you get a tangled file reference that requires several tries to undo - this could be calling the sleep routine instead of what it's supposed to do.
Switch off the TV from remote, then switch off the on/off button on the TV, remove the plug pin from the power outlet. Cool off for 48 hours and then retry. If nothing works, better refer it to a qualified service technician.
Hey, Firstly make sure all the plugs and cables have been plugged in (Securely) after this turn the power off by the mains then back on. If this does not sort out the problem take it back to the shop and ask the tech support for advise. :)
Check the electrical outlet which the tv is plugged into. Make sure nothing is loose at the outlet as well as on the back of the tv where the power cable plugs in. Another thing to try is plug a different device into that same electrical outlet and see if it turns on. If it doesn't turn on, it could be a faulty electrical outlet.If you've tried both the remote & the power button on the tv, a shot in the dark would be to change the batteries in the remote. You could always try calling their tech support at 1-800-256-2487. A last resort would be to return the tv from where you purchased it.
