Wheres the fuse so i can check if its the problem on the kv40xbr700

Unplug the TV's power cord and hold the power button directly on the tv ,keep holding it for 20 secs or so then let the tv sit unplugged for a couple of minutes before you try it again.

- Sit in the car with all the doors shut and windows up with your key fobs (all your fobs need to be done at the same time)
- With one of your keys turn the ignition on then off and remove the key
- Press and hold the unlock button and then press the lock button 3 times.
- Release all buttons and the locks will bounce up and down.
- Repeat this with the other key/keys (press and hold unlock and press lock 3 times, locks will bounce)

Try this reset, it may work:

-Turn Off power switch
-Select 90 degree washing
-Press and hold Start
-Turn ON power switch and keep pressed Start button 10 sec
-Depress Start button
-Turn Off power switch and turn On again and thats it...

Check all of the fuses inside. If none are blown, unplug and hold power button for 20 seconds thus resetting all of the capacitors. Plug in and hold power button for 20 seconds thus powering the capacitors up safely. should work

It sounds like there is a fuse blown in side. I had a similar result after I changed out the IC chips, There is a way to get the error code. Unplug the TV then plug it back in. Press and hold "Device" and "Menu" button at the same time. The power button will blink the error code. Mine was a 2 - 2 which meant it had a short. When I researched that it turned out my 5A Pico fuses where blown. I checked them and they where bad. I soldered in 2 new ones and it turned back on. In most cases if you have a 2 - 2 you will also need to replace the IC's. I got mine from http://www.tvrepairkits.com

Hello Hloggins, hi, your power supply is not producing the pulse needed to start the switching. check for the IC on the oscillator part of the power supply, you need an Oscilloscope to test this. if there is no scope. i suggest you replace the IC.
