Power light shows on . When pressing tv remote buttons power light goes on and off
Si eres tecnico revisa tus tiras de led porque probablemente algunos led se estan poniendo en corto o se estan abriendo nota esta revicion se debe de hacer tira por tira y si tienes probador checa led por led,si eres usuario llevala con un tecnico porque ese tipo de reparacion son delicadas por el manejo del display.
SOURCE: Clicking sound!
The TV is on protect mode. The clicking sound is the protection switch
that keep turning the TV off to prevent further damage, this happens
when a fault had been detected.
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
Also
ensure that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem with no receiver box
or dvd connected.
If that does not work, and you keep having a flashing
led on front of the TV, and tv turning off by itself after a while,
that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.
1The
internal circuits are jammed because of electrostatic
charges accumulating on capacitors, or because of a wrong voltage read
by the main chip on your monitor controller board. this started the
protection circuit.
2 The protection circuit detected a wrong
voltage or abroken contact, identified an internal fault and kicked in
, startingthe flashing light.
If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common faults
that can occur are a blown capacitor on power board, a
convergence IC has blown, or a fault on Digital board.
Check also
the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you
can get same flashing state because of the video cable.
If under warranty contact the manufacturer ringing the number on the user manual

if you replaced the supply board then there is issues with the decoder board as you would need to chec kthat and see if its not the issue.

You have a power supply or high voltage problem that system control is detecting that is keeping the set from coming on and possibly causing more damage. Have a repair shop check it out for you. Thanks for using Fixya.

Do you at least get a blue screen? Usually with no picture you get a blue screen. Try hooking up a DVD Player to it and see what you get... Good luck...Keep me posted ..Sincerely HDTV GURU JAY.

I see so many here with no sound/nopicture issues:
ISSUES:
1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.
Answers to issues:
1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.
2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.
Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.
What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.
3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.
4. Safety first--no TV set is worth getting injured or even killed over.
