Question about Samsung UA40C5000 40 LED TV
Last used the TV one week ago, took out the plug after using. Now, I plugged back in and there is no power at all, no red light, as if there is no power. Is there anything I can do about this?
Make sure the cord is pushed in all the way on the back of the tv. If it is then check for fuses on the power supply board inside the tv

look at list you will see reset
ONLY USE DOWN NAVAGATION KEY until RESET is highlighted
then PRESS RIGHT NAVAGATION KEY the tv will reset
PRESS STANDBY TO EXIT
the tv will need retuneing after
hope this helps

Problem: Samsung LTM1755B with only a blinking yellow LED when you try to turn it
Solution: I just had one of these come in. I opened it up, and found the U501 capacitor a little suspicious looking, in that it had a deformed top. It was a 470uF 16V electrolytic 105degC 10mm x 12mm. I replaced it with a very good quality 1000uF 16V electrolytic 105degC 10mm x 16mm Nichicon UHN1C102MPD. After that repair, when I tried to turn it on, the LED was yellow for a second, then green, then I got a picture, and it appeared to work great. I then asked the owner a week later how it was working, and they said it was working just like new!

You need some capacitors changed on your power supply. Easy job if you can use a soldering iron. I have a tutorial in my Tips & tricks. Remove the rear cover and locate the bad capacitors (little plastic wrapped canisters with swollen tops) near the top right of the tan PCB board on the left-mid side of the TV. Note the values written on then (1000uf or 2200uf) then head to radio shack and purchase the replacement parts. Ask for 16v or 25v parts (16v fit better). Replace the parts, put the rear cover back on and you are all set. I hope this was helpful.
