Samsung HLN 5065W TV comes on for 30 seconds then picture is out Can't Post

Hello:
This is my first post on the forum so I hope this will be a good one.
A co-worker of mine found a TV on a tree lawn. He plugged it in and he said the TV comes on for 30 seconds, then the picture goes out. The manufacturer of the TV is Samsung, and the model number is HLN 5065W. From what he tells me, he has found out the following:
1.) He's getting 386 volts at the balast
2.) All the thermistors are closed, indicating that that is not the problem
3.) All three trouble lights blink
Does he need to change the bulb? And if not, what is the easiest fix for this particular HD television?
This man is very technically savvy and I am not worried he can't do it himself, but this is not his field of expertise, as well as doing internet searches which is mine.
Thank you and I look forward to your response.
Steve

Steve (& I) may be ignorant (NOT to be confused with stupid) , but , I , for one , can't see the obvious answer as I'm not familiar with these types of TVs either....

Any further comments or delicious info you'd like to expose ????

1. If the 3 LED indicators flicker from the time the set is
turned on, it means:
1) The CN106 connector on the DMD board is not inserted
properly.
2) The MDR cable that connects the DIGITAL board to the
DMD board is not connected properly.
3) If the lamp does not turn on even after turning it on three
times, by powering off/on 15 second intervals:
a) The B+ 380V power is not supplied to the ballast
(The cable is not connected properly between the power
and the ballast.)
b) The cable connected to the CN110 terminal on the
DMD board and the CN2 terminal on the ballast is shortcircuited
or not connected.
c) The lamp does not turn on because 5V has not been
supplied to blue pin #1 on the CN2 terminal of the
ballast.
d) 5V is supplied to the CN2 terminal on the ballast but the
lamp does not turn on because the ballast has a failure.
(If the lamp is replaced and 5V is supplied normally to
the CN2 terminal, suspect a ballast failure if the lamp still
does not turn on.)
e) The ballast is normal but the lamp doest not turn on.
(When 5V is supplied to CN2 and 385V to CN1, but the
lamp does not turn on, try replacing the lamp. If it turns
on, that means it was a lamp failure.)
4) The color wheel engaged to the engine does not operate,
or the connector which indicates the operation of the
color wheel is not connected properly, and therefore
does not allow the lamp to turn on. The cause can be
determined when the set still does not turn on after
attempting to turn it on three times.
5) Another digital board or the DMD board has a failure.
Conclusively, if the three LED indicators flicker, first
check the above five items, then check the various
connector connections, and then suspect a failure of the
lamp or the ballast.Cool No dessert!

Hello jts1957:
My coworker buddy told me that your description of what he did to troubleshoot this unit is accurate. According to him, all the checks you listed checked out positive, and there are no problems. Therefore, this guy -- being worried he'll spend money for nothing -- wants to make sure that replacing the bulb is the only thing he needs to do to make this unit work. Would you believe he asked me if he could find someone that would accept it as a return if it doesn't work? Anyway, his cost on the part will be about one hundred dollars, so I cannot blame him.

Should ALWAYS ask the "knowledgeable" salesperson: "Does this unit require any "consumables?""
"What are they and how often will they need replacement?"
"How will I know when to replace each?"
"How much will each cost and where will I obtain them?"

Cost for the above: $0.00

I had a problem just like yours with another type of tv but it was the same problem. I solved that problem with my tv repairman.
