WELL IT MAY SEEM LIKE THE END BUT ITS NOT. YOUR TV HAS BAD CAPACITORS ON THE POWER SUPPLY.. THESE CAPACITORS ARE PREVENTING THE RELAY TO STAY OPEN AND GIVE POWER TO THE REST OF YOUR TELEVISION.. THAT CLICKING SOUND YOU HEAR IS THE RELAY OPENING AND SHUTTING DOWN.. THOSE CAPACITORS NEED TO BE REPLACED.. IF YOU OPEN YOUR TV AND FOLLOW THE ELECTRICAL CORD.. IT FIRST CONNECTS TO YOUR POWER SUPPLY... LOOK FOR BAD CAPACITORS THAT ARE BULGY ON TOP.. OR BLOWN.. REPLACE WITH SAME VALUE... THE VOLTAGE COULD BE A LITTLE HIRE.. BUT TRY TO KEEP THE SAME.. BEFORE YOU TOUCH ANY OF THEM.. MAKE SURE YOUR TV HAS BEEN DISCONNECTED FOR 3 DAYS.. THOSE CAPACITORS HOLD ALOT OF POWER EVEN AFTER DISCONECTED...

Hi

There are some factors of this kind of problem.

First you could have a failure in the power supply. Next could be the main board. Lastly you could have a problem with the panel itself, this would mean a new set for sure because the part cost is more than a new set.

However try troubleshooting the problem before spending money on repairing or replacing the television. Possibly you can restore the picture and sound to your television ...

Verify the TV is powered on by pressing the power button on the TV's remote or the front panel of the set. This may seem like an obvious step, but many TVs are equipped with a standby light that will illuminate if the TV is turned off, making it appear that the TV is on when it is not.Cycle through the TV's video inputs to verify that your TV is set to the right one. For instance, if you are attempting to use a digital cable converter box that is plugged into the Video 1 input and the TV is set to a Video 2 input that has nothing plugged into it, the TV will not display any picture or sound and may even say "No signal" on the screen. To cycle through the inputs, use the input selection button, typically labeled "input," "source," "TV/video" or the like.

Re-seat the video and audio input connections to verify a loose cable is not causing the TV's loss of signal. If you have a coaxial cable connected from your wall cable jack directly into the TV, it may have come loose thereby eliminating all picture and sound on the TV. Locate the connection cable or cables of whatever device you are attempting to watch and unplug them from where they plug into the TV. Plug them back in and check for a signal. If there is still no picture or sound at this point, the best option is to contact technical support for further assistance.

There are two power buttons on this TV. One on the lower left front and one on the right side. make sure they are both on. During storage it may have deactivated both of them.

Clicking noise from rear of set and no picture os sound and will not respond to controls .


This is a protection circuit that prevents the tv from coming on (to stop damage of the components) ....you need to check your voltages off the power supply and make sure they all read well (EX: 24v12v5v etc). Also look for popped capacitors that would make the values lower than need be for the tv to power on properly.


When you find the problem, replace the capacitors and then the other components if needed!


Please rate if this helps! :)
