For most do it yourself people this may not be something to tackle.

You would have to safely get the cover off the set and about the only thing you could do then is a visual inspection of the power supply board (follow the power cord to it) and look for damaged parts or puffed up filter caps--see attached photos.

Short of that unless you have a good meter and some other things this is likely a shop repair---keep in mind individual parts are not sold for any of these sets-----only circuit boards.

guessing which board is bad and replacing can get expensive.

The set should have a blink code (most of the Sony sets do) and the click you are hearing is likely the mechanical relay in the power supply indicating the set is trying to come on but does not make it, if you hear it click on and then click again that is shutdown.

May be time to have a tech or a shop look at the set.

Let me know if you have questions.

SOURCE: Power light comes on at plug in, on for 4 secs

The Tv is trying to boot and is hitting an error, entering protection mode, then reseting. With that model the most likely problem is a bad power supply. I would open it up and take a look for any clear problems (swollen capacitors etc) If you can you can google for a service manual to correctly diagnose the problem. It might be worth repair but for a 26 inch most likely not. Tiger Direct has 32 High def LCD 299 free ship right now.
If you can get a good price on a power supply and a main board this should fixyour tv. At your TVs market value (if your time worth anything) I would sell it as-is on E-bay and buy a new one.

You can check http://www.RNS-Systems.com
or E-bay for parts.

SOURCE: I have a Sony bravia KDL32 L5000. pressing power

Hello,

You need to check the output voltages of the power supply to see which one goes off. It may be due to short circuits some where, if otherwise
the power supply board is dead,do you know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Hoping that this will help to solve the problem.....

How to Take a Screenshot on Sony Xperia Z1


1) Go to the display or the screen in your Sony Xperia Z1 which you want to capture.
2) Take a screenshot. Press the Volume Down button on the side and the Power button for about 2-3 seconds. Make sure that both the buttons are pressed TOGETHER, otherwise it won't work.
3) View your screenshot. You will immediately hear a clicking sound, confirming that the screenshot has been taken. You may also see the text "Saving your screenshot" on your phone's display during the process.

My click botton to take the picture doesnt work, idk how to actually take the picture, am i doing something wrong??


When you connect the power adapter into the laptop, does the power LED light up? If not then - The battery adapter or the adapter's power lead or the laptop's power socket could be faulty. Check power adapter's DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard. This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

My Sony TV only powers up if I unplug H2


Sounds like you are in the right direction. Replace the board, but if your supplyer will not restock the part if not needed I would find a supplier that will.
