Stuck on standby

I'm a little confused here as without the 5 volt standby voltage the blue light won't come on, the TV will be dead like its not plugged in, are you sure you were on the right pin when you measured that? It almost sounds like your on the PSON or PWR-ON pin.

Ive had this tv for a couple of years now and its worked fine up until now, the red light comes on to show there is power but when i try to turn it on, the green light doesnt come on and it shows no sign...

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.4_26_2012_8_51_11_pm.jpg

Samsung LN40C610N1F. When plugged in, the red standby light comes on, but when I hit the power button the unit will not power on. The light doesn't blink or anything.

My LG 32LD320 won't turn on. I have no standby light and have even tried changing the fuse. Help please!

If total dead best way is to follow the AC voltage from power cord inside the set to see where voltage is lost.

Also , were you having any problems having to turn set on several times to get it on?

Samsung HLP4674W - changed bulb - still no picture - lights flash

If the lamp has been replaced I would think the Lamp ballast would be most likliest followed by the color wheel and then the Digital board. You can get any part needed for your model at www.tvrepairworld.com just leave them a email they respond quickly.

Logitech z5500 power problem

I replaced the fuse in the subwoofer. Solved the problem, without a hitch. Just take the current one out and bring it to an audio/hifi shop. Ask to buy a similar one.

PS. The fuse might look damaged, but then again, it might not. Have the audio/hifi guy test the current fuse, that way you know if that's the problem.
