SOURCE: LED Blinking

Okay 2 blinks isnt a error code, so your set isnt shutting down due to a protection issue, so I would suspect one of the low voltage regulator transistors or the horizontal output transistor as being defective

SOURCE: regarding 29gx1891/56r Philips Colour TV,LED keeps on blinking.

The problem was detected as a case of unregulated Power Supply Output. A sort of Crowbar is set in operation if the Power Out is above tolerable limits, which cuts off the supply to the Horizontal and etc. IC TDA 8362. The diagnosis was a faulty PWM IC 3842.

SOURCE: My KDS-60A2000 only can get my pc input 8 to show

I will presume you unplugged the set and waited and plugged it back in?

Also if using a box do the same (neither can hurt and may help)

As far as a fan issue---it may be the case or what can happen is the fans get coated with dirt and dust and slow down which triggers this type of alert.

Dust can be blown out but careful not to blow it into the set's image area or inside the screen.

Short of that locate inside the fans and watch when set turned on--one moving real slow may be the issue if not dirty.

I have samsung ultra slim tv, used ic tda 11105 v3/3 chip ic.The ,problem is when press stand by button the light blinking but tv not start.


The most possibility is a defective LED back lights strip. You may open the TV back cover, un-plug the cable between the main board & the power supply, supply the AC power to it, if the back lights do not light up, the problem is the LED strip, if the back lights light up, the problem is the main board.

Check your CRT boards on the end of the tubes for burn spots, and burnt components, check the resistors to make sure they are not shorted, burnt, and they read the correct resistance. Check the diodes to make sure they conduct in one direction only and are not shorted or open.

We had thunder storms my tv 65613 has a green blinking light wont star


Good Day,mikeybecerra; TV wont come on mb try these 6 items, please pay attention to the blinking light (it's a code) : 1. Check for no 8.4 volts DC at pin 3 of PC9A10 on the Power PCB, if low or missing replace PC9A10 part # 268P058020. 2. LED does not blink at plug in. Check for 3.3-volts DC at connector RF pin 3 (system reset) if low or missing suspect the reset switch S7L20 part # 432P109010 on the Control PCB. 3. LED does not stop blinking after plug in. Verify the standby supplies, 12-volts at connector KA pin 17, 6-volts at KA pin 18 and the 28-volts at KA pin 19, if the supplies are present suspect the DM PCB part # 934C067001 4. LED does not stop blinking after plug in. Check C9B01, C9B02, C9B10, and C9B11 (1000 UFD 16) on the DM PCB, if they are bad replace them with part # 181P734030 (680 UFD 16 V). LED stops blinking after 70 seconds of plug in but will not power on. 5. LED stops blinking after 70 seconds of plug in but will not power on. Check for 3.2 volts DC at connector RF pin 4 and 5 on the Signal PCB if low suspect problems with the switches/buttons on the Control PCB part # 935D736001 6. LED stops blinking after 70 seconds of plug in but will not power on. Keyboard is not locked and key inputs at connector RF pin 4 and 5 check good suspect the E2P PCB part # 934C061001. Good Luck, big IRISH.

Green light keeps blinking? Any clues


The constant blinking green light means that the TV is not booting up. This is a common problem on this set.You need to remove the shield from the DM board (standing upright on the left where the DTV RF connector is)and inside you will see the four leaky capacitors (1000 MFD 16 VOLT)replace them,plug the TV in and wait 70 seconds for the blinking light to stop,then turn on the TV.The hard part will be removing the board from the TV(lots of screws and connectors,takes time)
