Replace the following 4 capacitors on the power supply board They are CP624, CP639, CP641 and CP647 they are all 1000 uf 35V 105 degree radil capacitors. that should take care of the problem. If you need further help let me know.

Insignia ns-55l260a13 does not power on. Power led blinks 5 shorts, pause, 2 shorts and stays on. Screen blinks and nothing else happens afterwards.


Those 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/
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

-Press power off or leave with standby light on for 5 minutes (wait the full 5 minutes)
-Unplug TV / Press top buttons 5 times each to remove static from system boards (yes, each button 5 times each)
-Wait one full minute and plug TV in and press power on

Blue light keeps blinking won't come on


My lt27hv did that 2 weeks after it was unboxed. I plugged it into a power strip and when it acts up I simply switch off the power strip for 3 to 5 minutes than back on. Now it does this every month or so and this simple trick has worked so far.

Lcd monitor power light flashing with no img. seems 2 be frozen


The display is in safe mode and you will need to reset the display to get the display out of the safe mode. There are 2 different model revisions. Please choose the method that will match your revision. Depending on the revision of the monitor, one of the following 2 methods should reset it to a normal state. This reset generally requires both hands and it is sometimes easier with another person.

If the serial number begins with an A and/or your power button on the far right (5th button from left):
Method #1
1. Unplug the VGA cable.
2. Remove the power cable from the back of the monitor.
3. Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 3 down at the same time (see picture above) and while continuing to hold the buttons, plug the power cable back in.
4. Keep holding the buttons for 5 seconds after the power has been plugged in and then let go. The green light should be steady when you release the buttons.
5. If the procedure worked, the green light will go to amber and you should see a "No Signal" message on the screen for a few seconds.
Method #2
1. Unplug the VGA cable.
2. Remove the power cable from the back of the monitor.
3. Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 3 down at the same time (see picture above) and while continuing to hold the buttons, plug the power cable back in.
4. Keep holding the buttons until the 4th green LED blink; then, let go. The green light should be steady when you release the buttons.
5. If the procedure worked, the green light will go to amber and you should see a "No Signal" message on the screen for a few seconds.


If the serial number begins with a B and/or your power button is in the middle (3rd button from left):
Method #1
1. Unplug the VGA cable.
2. Remove the power cable from the back of the monitor.
3. Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 4 down at the same time (see attached picture) and while continuing to hold the buttons, plug the power cable back in.4. Keep holding the buttons for 5 seconds after the power has been plugged in and then let go. The green light should be steady when you release the buttons.
5. If the procedure worked, the green light will go to amber and you should see a "No Signal" message on the screen for a few seconds.

Method #2
1. Unplug the VGA cable.
2. Remove the power cable from the back of the monitor.
3. Counting the buttons on the front of the panel from left to right as 1 – 5, hold the buttons 2 and 4 down at the same time (see picture above) and while continuing to hold the buttons, plug the power cable back in.
4. Keep holding the buttons until the 4th green LED blink; then, let go. The green light should be steady when you release the buttons.
5. If the procedure worked, the green light will go to amber and you should see a "No Signal" message on the screen for a few seconds.

If you have tried the reset a few times and it does not solve your issue, please Ask a Question to submit a request through the system or call 1-866-752-6271 Option 1 to contact technical support.

FAST BLINKING GREEN & WON'T POWER ON


I had exactly this problem. After plugging and unplugging it multiple times over several weeks (even plugging it in quickly after it was unplugged but with the green light still flashing as suggested here) all to no avail, it just started working on its own one day. It worked for a few weeks and then the problem re-appeared.

InFocus tech support recommended:
1. Check whether the lamp door is securely closed.
2. Check the color of the LED and the number of time it blinks. (For me, a very fast almost flickering flash)
3. Does the fan operate? (My fan would go on when plugged in)
4. Remove the lamp module, shake it gently and reseat the lamp module.

For me, these steps did not work. InFocus then recommended that I send it to ProjectorDoctor http://online.projectordoctor.com/, and it was diagnosed with a bad power supply. $395, but it is fully functional again. Good luck.........

Sony LCD television will not power on.


I get 5 blinking red lights for about a minute or so before it powers back down. The Sony TV has a specific light that i presume is supposed to light up when the bulb is out. I'm unsure if this is what it is.
no picture, no sound. tries to boot with green light blinking a few times. then goes to red blinking light, six in all, then waits a few moments, then another 6 blinking red light.
Bulb was already replaced several months ago but we do have the TV on for long periods of time.
