HL-S4676S Video shuts down after ~ 40 seconds.

Read just about every thread on this issue i can come up with and I just cannot pin down the problem.
I got an HL-S4676S used for ~100.00 USD. It was broken and needed fixing I was hoping it was just the bulb but clearly thats not the case. Before replacing the bulb the TV would come on for about 40 seconds and then shut the video down and a few seconds later the audio as well and power. At that point it had 3 flashing LEDs. I pulled the back off and cleaned it all up and tried again. Same issue. I ordered a new bulb (this one ) same issue. Additional things I've tried:
Shorted out the thermostat: same results
Shorted out the door switch: same results
Forced the ballast on: Lamp comes on and stays on but no picture at all.
SO to recap. With the new lamp. I can power on the TV and will have a picture for ~ 40 seconds. It then shuts down. I power it back on I will have picture again but for 10 seconds or less. After that it will not come back on and there is a new sound rather high pitched coming from the light engine. At this point I have to leave it off for an hour or so before I can get picture back again.
Suggestions?
