sounds like a button problem, your remote seems to be in programming mode,
I would take apart and clean,
Take batteries out 1st.
# 2 Take a Q tip with rubbing alcohol and swab your keys.
# 3 use some compressed air to blow out and dry keys.
# 4 Re- set your TV to factory reset.
Power tv up and follow instructions to remote set up.

Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.
The good news is that the "No Input Signal" message means that your TV is not broken. If you are trying to watch cable, then you have simply turned the TV to the wrong input channel. If your cable comes into the Philips using a coaxial cable wire, use the Philips remote to change the channel to Ch.3 or 4 - whichever channel you normally watch cable on. Make sure the cable box is turned on if you have a cable box. If the cable box connects to the TV using another type of wire, use the Ch+/- on the Philips remote and go through all the AV channels until you find the right one. Good luck! Let me know if you need additional help.
I put heat-sinks on U14 and the regulator above it and the TV has been running fine all day. Always shut off after 14-30 minutes before. Heatsinks were just 1/2" x 1" metal strips with silicon thermal compound that I taped up to hold in place to temporarily test, as it is obviously a heat related problem.

I had a 26" Samsung LCD that wouldn't turn on, and the red light stayed on too, so I knew it was getting power. I found some info out there and figured out how to fix it. Also made a video to show others. I'm a complete newb so if I can do it, I know a lot of others can too. Make sure you research stuff and be safe when fixing it. I take no responsibility if you mess up your own TV! But like I said, I fixed it, so I figured almost anyone can. Also, it only cost me $1.40.
