Tv have a power supply board problems.That the board where the tv power a/c cord plug into it.Must take the aparts to troubleshoot and repair or replace a whole refurbish tv power supply board.U have all the tools and understanding basic electronic also can do basic soldering work?Yes?Take the tv aparts and check the tv power supply board carefully looking for any dying and leaking capacitors components parts.These dying and leaking soon to be dead capacitors parts are alway bulges up or puffing up onto it tops.These dying capacitors components are the causes and the problems for tv power LED indication light flashes and clicking noises.U must replaces all these dying and leakages capacitors components parts to fixed ur tv power supply board.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

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 to buyand 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.If set is opened at least look for puffed up and bad caps like in thisphoto.
Not likely anything you can handle, consider a shop taking a look at the set to give you an estimate.

The main board would be susoect next if the power supply has already been replaced.
