Samsung DLP model# HL-T4675S-----HELP

[dozyp]

I have a Samsung DLP model# HL-T4675S. It shuts itself off and then the three lights start to blink. I turn it off with the remote and have to wait for the lights to stop blinking. I turn it back on, I can hear the color wheel start to whirl, the lamp lights up, no clicking sound the tv turns back on for a few mins maybe less and then shuts down again. I replaced the lamp and Like I said it does light up, can you tell me what is wrong?
