Re: dlp tv problem
Is the lamp light the only one thats flashing? Does the buzzing your hearing stop or is it constant? Also when you press power off does the buzzing stop instantly or continue? Respond to this post and I will try to assist you. Is HL-R677w the correct model number also?

The answers above are correct. It's either the lamp or the color wheel. Testing the lamp is pretty straight forward. Use an Ohm meter to see if the it's filament has continuity. It's unlikely that a good color wheel would fail immediately after changing the lamp. Look to see if some wiring is out of place and rubbing the wheel causing the noise you described. A jammed but otherwise good color wheel would cause the TV to shut down and display an error code.
Sounds like a bad color wheel----remove lamp---the wheel faces it--look
for missing pieces or the wheel shattered---these are known for the
wheel making a loud high pitched sound or even a grinding sound if the
if wheel bad You Tube has video instructions for
replacing it---seen several people able to do this themselves in about a
hour. Google the model number to ("color wheel") to locate a
replacement on the internet.
