rinchman,
I'm not able to determine from here what the problem might be.
Your best bet would be to call 800-SAMSUNG and have a technician come out and take a look at your unit.

I WAS WATCHING MY SAMSUNG HLR5087WA/WAA WHEN A LOAD EXPLOSION CAME FROM THE SET AND THEN IT SHUT DOWN. I REPLACED THE LAMP WITH PART # BP96-00677A. THE SET CAME ON FOR A FEW SECONDS AND THEN SHUT BACK DOWN WITH THE STANDBY AND LAMP LED ON. I EVEN TRIED REINSTALLED THE LAMP AND HOUSING BUT GOT THE SAME RESULT. ALSO WHEN IT COMES ON THERE IS NO SOUND. COULD THIS BE A BAD LAMP? OR A BAD BALLAST?
