If you replaced the lamp you want to make sure the lamp cover is back on correctly. If all that has taken place then you will need to have a technician look at your TV as it sounds like you have a power supply failure.

Well, at least the standby 5vdc circuit is still working but the problem can be in the controller board is not sending the signal to turn on the main power supply sections, or the power supply itself is bad. Look at the power supply first for burnt parts, bad capacitors.

SOURCE: Power Issue
Now,u plug in the tv u get a solid red standby power red LED light in the front of the LCD panel right?When u push the power button on the remote u hear a clicking sound?Only one clicking sound,not the power supply board problems.It the Tuner board problems.But u can make sure it the power board problems or not.By taking the tv aparts check the power board,that board where the a/c power cord goes into it.Look all around the power supply board check for these leakage capacitors,they alway bulges up it top or puff up it top.No bad leakage capacitors,then it not the power supply board problems.

Testimonial: "Thanks for your immediate reply. It could be an issue with the TV's tuner. At times, I did noticed the sound wasn't clear after turning on the TV. I had to turn the TV off, then turn it back on to get a clear sound. Now, the stand-by red light immediately clicks off when plugging into the wall socket. The television is now in a TV repair shop. "
If you have no indicator in the front at all, it means that the 5vdc standby power supply is not working, it needs this voltage for the TV to start up. Please read my guide to understand more.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:
