How do i fix the Lip sync on our new TV?


lip sync is the combination of the two signal carrier frequencies being out of sync
one signal carries sound and the other the picture and they normally come together correctly but that can be upset by a blip in the power supply, problems in the signal from the station or atmospheric disturbance
try changing channels a few times , try shutting the set down and then restarting it
read the operators manual for any clues in the trouble shooting section
Lastly talk with a repair shop for any advice on how to fix

Dell xps touch sreen just blinking blue light but blank screen


Sounds like it went to sleep due to low battery power. May be time for a new battery if it isn't holding charge well.

Plug it into the wall and push the power button once. It may come back on. If not...

Hold the power button down until the machine shuts off completely. If that doesn't work, remove the battery.

I use my flat screen for a computer monitor it shut,s down if not used for 10 min. how can I fix it


Change the settings for the power save options in the TV and see if it has some timer for no signal.

Alternatively in the PC you can select a screen saver that has a moving image which means PC will always give a video signal even if it is not used.

LG TV Goes Into Hibernation (I Think)


This could be two things 1- a power saving mode in the TV... go into settings on the TV, look for either "power save settings" or "energy star settings" go in and turn that off. 2- it could be a screen saving mode because the TV has lost signal...some HDDVR receivers such as Direct TV DVR etc...have their own power saving mode, after a couple our of inactivity, they turn off, which kills the signal to the TV...so the TV shuts down because it has no signal coming to it.... if that is the case, you need to go into the settings on your cable/satellite settings and also look for a "power save mode" or "energy star saving", and turn that off.

My screen is dim, i can just make out the screen and what i am writing. I have tried the power saving options, brightening the screen and nothing helps, anyone know what it could be?


have you tried holding Fn and pressing the button with thr brightening symbol. on mine its Fn and F5 for brighten and Fn and F4 for dim.. buttons may vary but this should work if not you may have a fault with the sreen sensor that shuts the screen down when you close the notebook

No sync means no video signal to the monitor. The rest sounds like a corrupted OS. This could be from a number of reasons, including a virus. If you have NORTON or MacAfee, Your open to a lot of attacks. Get AVG free, and use Mozilla instead of IE.
The reason the fans come on full speed is the MB senses a high temp on the CPU, until the bios fan control takes over after POST. This is normal on most systems.
