there is a easier way to check your remote. Open your radio on AM frequencies, you don't need to be tuned just noise is perfect, then bring your remote near the antenna and press some button. You will ear the frequency in your radio. If it works this way but not on the TV make sure to press the TV button before using it (if the remote is universal).
Sounds like the video board when bad. I would say the TV went defective. Use the 90 day warranty to exchange for a new one.
Always use warranty at this point because the newer TV coming out in these days have very lame warranty.
Hi , I have the same problem with my LT-42X688,so i called the service of my extended warranty provider . the TV technician just left and told me the motherboard is the problem. he said its the third one this week he has seen with the same symptoms. he ordered the motherboard and i've got to wait 5 to 7 work days before the part will be in . I will keep you posted when the guy will return.
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!
