There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for 5 mins, then try.

If you aren't tech savvy, this unit needs to go in for repair.

If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering, and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.

Green orange then red flashing 3 times light


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

Hi, if I change my computer to my Nissan 300ZX 1986 I have to reset my computer or simply change it. Thank you for answer.


There is no re-setting. You just change it out. Be sure and disconnect battery before unplugging the ecu. It's a simple swap and go.
If yours is like my '87 Sentra, there is no trouble code capability, but there are limited diagnostic functions. The red and green LED lights and the diagnostic switch (on/off), can tell you if problems are present in the system or not. You just have to follow the diagnostic procedure.
Here's how: Make sure diagnostic switch on ecu is off. Run engine at 2000 rpm for 5 minutes, at no load. Look at green led: if it flashes at least 5 times in 10 seconds (that is the oxygen sensor making it flash), turn car off. Turn diagnostic switch on. Turn key to on, do not start engine. Check led's: if red is off and green on steady-No problems present in system.
If the red light is on and green light is flashing, post back and I can furnish the rest of the diagnostic procedure-basically, you will be checking voltages and resistance of all solenoids and relays the ecu controls. The green led may flash in two different sequences (either longer flashes and short pauses, or longer pauses and short flashes) when in diag. mode (with the red led on), and that will lead you down two different diagnostic routes. Pretty simple, really, and pretty effective. Took me hours and hours before I realized I even had this diagnostic function.

I have a Sennheiser MM100 Bluetooth headphones that has stopped responding. It will not turn on/off and the LED light is blinking a continuous blue. How do I get it to function again?


Found this online. Hope it helps you out.

Switching the headset on
To switch the headset on:
Press and hold the Play/Pause button for 2 seconds.
An ascending confirmation beep is heard in the headset and the LED indicates the current operating mode. Flashing in blue indicates that the battery charge status is OK; flashing in red indicates a low
battery (see page 6).
The LED flashes several times every second:
The headset is paired to one or several Bluetooth devices and tries to connect to one of these devices.
The LED flashes slowly (once every second):
The headset is paired to one or several Bluetooth devices. However, there is no current connection because the
Bluetooth device is switched off or out of range.
The LED flashes once every 3 seconds:
The headset is paired to one or several Bluetooth devices. However, there is neither an audio transmission nor an active call.
The LED is glowing slowly every 4 seconds:
The headset is paired to one or several Bluetooth devices, a sound file is received via A2DP and played back or
paused.
The LED flashes once every second:
The headset is paired to one or several Bluetooth devices and there is currently an active call.
If you switch on the headset and keep the Play/Pause button pressed for 5 seconds, the headset will go into pairing mode (see ?Pairing the headset? on page 9).
The LED flashes alternatingly in red and blue for up to 60 seconds:
The headset is not yet paired to any Bluetooth device. Pair it as described under ?Pairing the headset? on page 9.

Hello I have a 1994 maxima manual transmision,it have a check engine light on,when I start the car and beguin to drive it,runs perfect the a few minutes later the car gets very lazy almost want to turn...


Hello! I'll need the trouble code to fix your vehicle...Below is procedure with a code list...Guru...saailer

Remove the trim panels in front of the center console. Locate the engine computer attached to a floor-mounted bracket on the transmission tunnel between the console and the firewall.

  • Turn the diagnostic mode selector, located in a round opening on the side of the engine computer, until it stops. Observe the small red and green LED lights on the side of the computer next to the mode selector. They will flash to indicate the modes, with a pause between each mode. One quick flash is mode one, two quick flashes is mode two and so on. When the light flashes indicate mode three, quickly turn the mode selector counterclockwise until it stops. You have entered mode three diagnostics.

The red light flashes to indicate the "Tens" digit of the code and the green light flashes to indicate the "Ones" digit of the code. For example, if the red light flashes two times and the green light flashes seven times, this would indicate code 27.

    LED light has gone out


    Lights up blue when the Drive is powered on. Flashes red when reading or writing data. It was just stuck between color as it does not flash green,red-blue make green. Contact the company and see if it is under warranty, if not see if they will send you a new light, because
    if it is not under warranty,it does not matter if you open it.

    All that is inside is a hard drive, chip board. The light plugs onto the chip board same as a fan plugs onto a motherboard. I hope this helps you and it is under warranty,or at least they send you a new light if not.

    The following procedure will re-establish the communication link between the Headphones and the Wireless adapter, this is called "pairing". Before you start please make sure both the headphones and the wireless adapter are fully charged and turned off.
    Note: The headphones and the wireless adapter come pre-paired from the factory.
    1. Press and hold the power button on the headphones. See Figure 1.
    headphone.jpg
    Figure 1

    2. Continue to hold the button down until the LED starts flashing red/blue in an alternating pattern. Release the button when the LED starts flashing red/blue. See Figure 2.
    headphone-flash.gif
    Figure 2
    3. Once the headphones LED is flashing red/blue, press and hold the power button on the wireless adapter. See Figure 3.
    receiver.jpg
    Figure 3
    4. Hold down the button until the LED starts flashing red/blue in an alternating patter. The LED will blink blue, then turn off for a few seconds then blink red/blue. Release the button when the LED starts flashing red/blue. See Figure 4.
    receiver-flash.gif
    Figure 4
    5. Once both the headphones LED and the adapter LED is blinking red/blue, press the volume up button once on the headphones. See Figure 5.
    headphone-volumeup.jpg
    Figure 5
    Once the headphones is paired with the adapter, the LED on the headphones will blink blue once every two seconds. See Figure 6.
    headphone-flash2.gif
    Figure 6
    When the adapter is paired the LED will be solid blue. See Figure 7.
    receiversolid.jpg
    Figure 7
    The adapter may continue to blink red/blue for a few seconds even after the headphones LED starting blinking blue. This is normal; the adapter may take a few additional seconds before the LED turn solid blue.
    Once the headphones and the adapter are paired, it is not necessary to pair them again even if the batteries on both units are completely drained.
    Additional Note: Repeated pairing will not improve the sound quality or give the headphones and the adapter a cleaner connection.
