First thing you do is to check the outlet if there is a power output the check the power cord and plug.If there 's a power in the power cord,Check the fuse of your television.The fuse is located at the power supply.You can see the power supply when you open the back cover of your television at the upper right side.Replace the fuse if busted with the same value of fuse.That's the step you can do first..Thanks..

My samsung tv is making clicking noises and won't turn on


Clicking noises may mean a power supply voltage is not staying correct or that board is bad---a suggestion: visit shopjimmy.com who has by model number a list of all the boards used in almost every Samsung Flat screen set made.

Element tv Model ELCHW402 won't turn on


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.5_25_2012_3_07_58_pm.jpg5_25_2012_3_08_17_pm.jpg5_25_2012_3_09_15_pm.jpg

We have a 46 inch sharp tv model number 46SB54U won't turn on. The green timer light is flashing. We just replaced the power supply board thinking that was the problem. TV still won't turn on...


Hello,

Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

I hope this will helpout ......
