This is not a user repairable fault. Should be checked from its main power regulator board, and is a skilled work. Actually this is a repairable fault, but can do only by any technicain.

Hi there! The panel may be in protection mode. The Inverter board is the most logical area to start after checking power supply Voltages.(5,6,24 and 13Volts). There may be coils on the Inverter Board which have bad soldering or faulty. Other than this it may be main board which controls switch on or off. If all else fails, refer to a repairer. Beware of High Current!!! Best Wishes and Good Luck, Jus004

re: sony flat panel lcd tv mod. # klv s 40a10.
No power. When power button is pressed, nothing happens.
The stand-by at the power supply ( cn6201) measures to be 3.47 v. instead of 5 v. However, when I unplug cn6201 (5 pin connector) I can read 5v. at the power supply.

Probably out of warranty?
this is an issue with either one of two things,
1) Power supply
2) Lamp 'Florecent back lighting tubes' ballest.
Depending on the service shop rates, the labor is more than the part. Call around and get some price quotes. Worth your time. These set's are still expensive?
Now if it's a 15" . Buy a new one. They are just a throw away item these days.

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!
