No power-Will not power up with the remote or power button

I checked the fuse and it is good on the G board and it is good(F6001).Is there a way to check the power supply?I have a little bit of experience using a test meter,so any help would be great.The tv was given to me as a no power up so dont know anything else about it.I had it apart(as far as the panels and all,but dont see anything like lightning damage or sort.It is a very clean tv.If I have to get premium support let me know.I would really like to get this tv working again.

Samsung HP-T5044 will not turn on


Check for any missing voltage from the power supply board to its other boards. Is there any blinking of LED occurs when you switch ON the TV. If yes, count the number of blinks at one time. It is fault indications. Just visit this site named Electro-help. Sometimes you will get details about this fault there. check this link and select the site.

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.4_10_2012_10_50_35_pm.jpg

open set and look for caps like these that are puffed up on the power supply board(follow power cord to it).

The TV will not turn in (by remote or from the tv)


Is the standby LED light off ? Do you hear clicking sounds when you press the power button on the TV ?
If not it's probably the power supply board. Look at the fuses(s) on the power supply board. If the fuses are good you may have to replace the board if bad.
