It sounds like it since you have the 14v going to the inverter. Repairing inverter boards even on lcd's is 50/50 shot, so let's give it a go. If you have a dvm check the ohms on the inverter xformers ( if more than one) they should be identical in resistance. Check or replace all electrolytic caps on the board. That's about all you can do outside of replacing it, Oh, see if you have a 5v source going to in inv. bd also, check that.

SOURCE: turns itself off

Either lamp is failing (not covered under any warranty), or the ballast has failed. Or it may be a problem with the power supply, or even the fans... What is the picture next to the flashing light? If it's only the lamp light, then either lamp or ballast, if temp is flashing (the thermometer), it will be fans, temperature sensors, main board or power supply.

SOURCE: 32" Samsung TV, No Power or Sound, power LED on, flashes 3 times

Most likely the set has lost vertical sweep or the feedback from that circuit. This will shut the set down to prevent a horizontal line from burning the face of the CRT. This will have to be looked at by a technician.

SOURCE: samsung lcd tv ltm1755b won't turn on (power light stays red)

Problem: Samsung LTM1755B with only a blinking yellow LED when you try to turn it on.

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!
