Can't edit my original post. My set is a HL-S5087W. I messed up the title, sorry.
I replaced the lamp in my set a few weeks ago as it had finally bit the dust. All was fine until last night when it decided to just not come on. Now when i turn it on I get the chime, the "lamp" light on the front panel flashes for a few seconds and then shuts down. I took the back cover off, held down the door switch and turned it on. The fan comes on and I hear a clicking sound but the lamp does not come on.
