When we turn the power on, a little light blinks 3 times.

what is the model of your tv?

Power supply probably fried. You will have to take the TV apart to test.

Hi,


This may cause by an electrical charge in the motherboard itself,Im not really sure how it affects the display of the computer.There's also a possibility that the problem is with the LCD cable or the LCD itself. Please follow this method since it usually fix such problem like that,


1.Removed the battery then unplugged the AC adapter


2.Press and hold the power button or the ON/OFF button for at least 30 seconds


3.Connect the power supply back to your computer then turn it back on.


4. Check if you will see any difference.


5. If nothing happens, try to press and hold Fn and F2 on the keyboard.


If nothing happens, there is a possibility that the problem is with the LCD or monitor itself, maybe it will need a replacement...


I hope this information will be helpful. Thank you for using FixYa...

If the front power light is blinking three times then your TV has a problem with the convergence. You can get the correct replacement parts and full step by step photo instructions from www.TvRepairKits.com

It has enough juice in the battery to light up the lcd lights but not enough to turn it on. Could be the power supply. Consult a reputable service center and have it checked out. Good luck.

The blinking red light at the the front of the television is the "Diagnostic STANDBY/TIMER LED".
This little red light will blink 2, 4, or 5 times and then stay off for three-seconds. And blink again for 2, 4, or 5 times. This cycle repeats. The most common diagnostic code is the 4-blink code.

When the red LED blinks 4-times, it means one of two possible causes:
1) +13V is not supplied on the A-board. Or, 2) IC502 is faulty.

It is best to take this television set to a repair facility and ask that the +13V power supply be repaired.
The copper tracks and integrated circuit pads are very thin and delicate on the KV-24FV12 circuit board, and will easily lift off of the circuit board, if the incorrect desoldering tool is used. Unless one has a good quality PACE vacuum desoldering unit, one should not attempt to repair the television.

If ti blinks three times, then it may be an issue with the flyback transformer. It's called "three strikes"...it tries three times to come on, and after that enters a safety shutdown mode to protect the TV. Might need to have a professional shop take a look at it.
