Inside there is probably a dirty and/or broken relay.

The clicks are coming from a mechanical relay in the standby supply for voltage---the standby power supply runs 7/24 if set is plugged into power.

What I would do if you are able is open set and on power board (power cord goes to it) look for and replace any filter caps that are puffed up there--the relay is possible but rarely bad in this way unless a solder connection under it is bad.

If caps are good you have a connection or bad part near the relay that likely is causing this problem.

Look closely at filter caps in power supply:

even one that is slightly puffed up can cause this, if find that and need to know what and how let me know.

Look for loose contacts in power outlet. Try the TV on some other power outlet. There could also be a problem with the power cord.

Hi I just moved plugged in my ps3 the red standby light came on and now nothing it won't even try to turn on what should I do ?


Sorry I had no idea you sent me this message until today. I apologize for the delay. You probably found a solution by now but if you haven't, please try this..

Solution:

  1. With the PS3 in Standby mode (Red light on), press and hold the Start button until you hear a single beep, followed by double beeps.
  2. Connect the controller using USB cable and press the PS button on the controller.
  3. Now, the system restore screen (or whatever they call it) will come up like this

  4. You have several options here for restoring the system, some will unfortunately wipe up all your data, others will make you lose the file naming.
I hope this helps :D

Bluetooth wont charge or power on. when charging the red light comes on. once disconnected from charger it wont come on


Indicator Lights:
1.Headset Status Headset Indicator Light
2.Powering on Steady blue, then intermittent flashes
(changes to standby mode)
3.Powering off Red appears and goes off
4.Standby Blue intermittent flashes
5.Charging battery Red solid light. Light indicator turns off when
battery is fully charged and headset is off.
6.Low battery Triple red flashes
7.Pairing mode Blue/red alternating flashes
8.Missed call Purple flashes. Press the call control button
to cancel flashing light.
9.Incoming call Triple blue flashes when ringing.
Power on and off:
1.Turn on the headset Press and hold the call control button until the
indicator glows blue. You will hear ascending
tones.
2.Turn off the headset Press and hold the call control button until the
indicator glows red. You will hear descending
tones. When power is off, indicator stays off.
If none of this is helpful then it may be that your battery is dead, if that is the case then you will need to replace the whole headset. The battery's are not replaceable.

Good luck from Headsets Direct!

My 40' vivo tv has turned off and won't turn back on but the red stand by light is on??


If the standby light is on and it does not respond, it is most likely to be a problem with the power supply . First try this, unplug and leave the set like that for a few hours. Then plug it back in to see if the tv attempts to turn on when you try to power it up. See if you hear a "click" even if it goes back to standby. Let me know what you found so that I can help you test the power supply board to confirm, if necessary.

I press the power button and hear the click but no picture appear


Unplug the TV Remove the cover wait until the TV cools then plug in, turn on and, it should come on... if it does; purchase a computer fan to cool the chassis of the TV wire it into the 12 volt side of the power supply and, install the cover

Red light comes on but the shuts off?


Mine did that and it really pised me of, sony told me to turn the power switch onthe back of the console on, when the stand by light comes on to push and hold the on button for at least 3 seconds until you hear a second set of beeps. This however didn`t work so I sent it back to Sony Australia and got it fixed up no worries.

TV, i plug it in, turn it on, no image, "on timer" light comes on.


If you dont hear a click theres a problem in the standby power supply. if you do hear a click theres a problem in the Main power supply or sweep supply. Get a good tech to look at this for you if your not a tech. Good Luck
