1. Try this - hold the menu button down for 10 seconds. TV should power up; youwill have to turn off front panelbuttons on menu.

2. You can also try a hard reset: Unplug TV from AC mains and remove all cablesfrom TV. Wait about 30 minutes and re-plug to AC power and redo the cabling.Switch on the TV and see if it works..

3. Powering down the set or putting it in standby may haveallowed the power supply to cool. Weak capacitors often go out of spec whenthey cool, thus preventing a section of the power supply from firing upproperly again. There is a simple trick...just warm the back of the TV with ahair dryer for 5-7 mins after you have unplugged the TV. Look for the littleareas of holes in the back panel of TV. Use these as your guide at where to usethe hairdryer, but don't hold the dryer too close (say 5-6inches away). (Makesure the dryer is on High heat). If the TV doesn't turn on after you haveheated it up (like it tries to come on but then turns off) you need to unplugthe TV again, this resets it. And repeat those steps till it works. Resettingthe TV after it fails to turn on is the key. Also, just leave the TV on. Don'tturn in off. Since it is LCD, it doesn't take much power...only a few bucksextra a month for your utility bill.

4. A circuit board may crack about some of the largercomponents mounted on it. You can inspect the PCB's for fractures, and thenrepair them. It may also be poor soldering that has failed. I would be checkingfor these things first.

5. If you want to go in for a long term solution, you can easily replace thewhole power board or just change the faulty capacitors. You will have to openthe back panel and take a look. You can make out which are faulty, becausetheir caps will be swollen on top. Here's a sample pic of a bust capacitor (notsame model):

Check the specifications of the faulty capacitors, and get the replacementsfrom your local electronics shop. If you are comfortable with this, you can usea pair of needle nose pliers to G-E-N-T-L-Y pull out the defunct capacitors.Once that is done, solder in the new capacitors carefully. If are unsure how todo this, try to get a friend who knows how to do this kinda stuff do it foryou, or get a qualified technician. Warning: If you do nothave a background in electronics repair, or are inexperienced, get a qualifiedtechnician to do it for you.

REMEMBER there are very dangerous voltages inside a TVthat can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECTTHE POWER BEFORE YOU DO ANYTHING.

Hope that helps!

How do I disable power save mode


Press the Power key > Activate power saving. To deactivate power saving mode, press the Power key > Deactivate power saving.
When activated, the power saving mode turns off some functions automatically. Radio configuration in power saving mode include the cellular radio (it is set to 2G/GSM only mode), the Bluetooth radio (it is turned off) and the Wi-Fi/WLAN radio (scanning for new networks in turned off but existing networks keep functioning). The power saving mode also reduces display power consumption by minimizingscreen brightness and by turning off touch screen feedback and theme effects. In addition the vibra alerts are turned off in a power saving mode. Hope that helps Anomy.

Can't turn on power to desktop


Simple power hack, to do this, kind of like hot wiring your computer.

Turn the power on at the wall, Flick the switch on the back of the computer (if there is one on the back) to the on position, make sure the cable is plugged in, and turn the power off at the wall, hold the power switch on the front and turn the power on at the wall.

This will cause the power to jump across the switch, causing the computer so sound a bit like a motorbike being started.

The power will come on it will turn over click and go off. After this turn the switch of at the back of the computer, and turn it back on, and the computer will boot up.

The first bit of this is just charging the capacitors in the power supply, the second bit is turning your computer on.
