You most likely have some faulty capacitors on the power module. You can easily identify a bust capacitor. They will have swollen tops. Here is a sample pic:
Check the specifications of the faulty capacitors, and getthe replacements from your local electronics shop. If you are comfortable withthis, you can use a pair of needle nose pliers to G-E-N-T-L-Y pull out thedefunct capacitors. Once that is done, solder in the new capacitors carefully. Ifare unsure how to do this, try to get a friend who knows this kinda stuff to doit for you, or get a qualified technician.
Warning: If you do not have a background inelectronics repair, or are inexperienced, get a qualified technician to do itfor you.
REMEMBER there are very dangerous voltages inside a TVthat can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECTTHE POWER BEFORE YOU DO ANYTHING.
If you want to go in for a long term solution, youcan easily replace the whole power board. You can get spare from HERE.
They also offer FREE online technical advice as you do the DIY..
Hope that helps!

Did your replace lamp come on the screen or did you lose picture? Just because the LED indicator suggest replace lamp it doesn't mean it needs it. If your pix was dull or loss of brightness then replace it, if not then just reset your lamp timer, check your owners manual for instructions.

What it sound's like is that the lamp ballast is the problem. Buzzing sounds like when the power is first brought to the ballast it has to ramp up the voltage to get the lamp to light, then the voltage drops back down when the lamp is lit. Sounds like the lamp ballast isn't ramping up the voltage the way it should. May have to replace it. A good service shop would be able to do this for you.
