Dear sir/madam,

It is almost certain that the power supply unit is in what is termed Hiccup mode which is simply the power supply shutting down when a fault is sensed , of course when the set is switched off the fault can not be seen so the set switches on again whereupon the fault is sensed again so the set switches off , ad infinitum , hence the flashing power light ! Usual cause is short cct line out transistor or transformer .

Second, is the tv cabinet or table where the tv is placed moving?if so. check out for loose solders especially the power supply section(regulators),and power aux supplys. if the symptom still exist.a certified tv technician is needed.


Thanks
Good Luck

    TV light :

    When it shuts off. Try doing what's called a self-diagnostic test.
    As soon as the television shuts try these steps.

    Pressing on the front panel's ?INPUT? and ?MENU? buttons at the same time, and holding for 5 seconds,
    activates the Self Diagnostic Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem
    has occured since the last Initalization.

    Please do Note: The front panel buttons must be used, NOT those on the Remote Control.

    ? The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
    ? The flashing then pauses for approximately 1/2 second.
    ? The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
    ? The Error Code is repeated a total of 5 times.
    Example: If the Error Code is ?24?, the LED will flash two times, pause, and then flash four
    times.

    The Error Code designations indicating a malfunction, or no malfunction, are listed below:
    Self Diagnosic Code Description
    1 - 2 = no error detected
    2 - 1 = X-ray protect (high voltage or beam current)
    2 - 2 = Short protect (short protect monitors low voltage supplies)
    2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection)
    2 - 4 = Vertical protect (usually loss of vertical from the source).

    Good luck!

Heard a pop , bulb blew out , replaced bulb , it worked for two days , now red light blinks three times pauses then three times and so on , tv won't turn off light won't turn off unless I unplug...


3 blinks indicates lamp door is not on or has not been reinstalled properly. This also could mean the lamp door switch has failed itself. Try removing the lamp door and putting back on, if that doesnt correct the problem then I recommend having the switch replaced.

When TV is turned on, green power light comes on and picture starts to come on, after a couple of seconds the picture goes out along with the green power light and the red standby light comes on and blinks...


Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.
  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

I was watching TV and all of a sudden the screen went blank and wont come back on. I can unplug the TV and when I plug it back up, you can hear it clicking like it wants to come on but doesnt. The light...


Hi, you failed to mmention what make and model the tv is. But it sounds to me like a Samsung from experience. If it is then you need someone to check the power supply capacitors. The ones with bulging tops are faulty and need replacing. If it isnt a samsung, still look on the power supply pcb for signs of this and you will be on the right track.

We have a Philips 4 BDS4231R/00 and it does not start. We can here the relay sound and if we turn it on and off say 7 - 10 times it works fine. Could anybody tell me how this can be fixed. Please


Hey John, I am experiencing a very similar problem. If I unplug the TV when it is on (green light) and plug it back in. It begins green, and clicks to red. I immediately turn the TV back on with the remote. Most of the time it seems to struggle for several seconds, sometimes with a little scratchy audio popping in and out. It will then go from green to red on the TV and if I try to turn it back on it will go green for a few seconds and back to red but without any click coming from the TV. No matter how many times I try after that, no TV. If, on the other hand, I unplug while green, plug it back in and with the remote turn it back on after it has come up green and then clicked to red, it will come on. It might take thee or five times but at least it comes on... If you hear of a real solution, please let me know (bennettkw@hotmail.com) in the meantime, best of luck.

Philips 42PF7320A blinks 3 times every time i hit the power button


The SSB is small self contained board that u connect your Antenna, and HDMI to. An error three is a communication error between the SSB and to Logic board ( located underneath the SSB on the back fo the plasma panel that is just below the power supply. U can check parts.com and see if u want to purchase a SSB for this TV. Is the 3blinking lights coming from the front of the TV. Also check the power supply and see how many times the green led blinks on the upper left of the power supply and let me know.
