DLP Time Delay Bulb Intensity

I have a Samsung HL-T5676S DLP 1080p
TV/Monitor purchased in early July and is now 3 months old.
I have a problem (or not,I don't know) that is very subtle.When I first
turn the set on (power up from standby) it takes almost 2 full minutes
to get to average viewable watchability for brightness.After that period
it flickers (5-6 times a second) for almost 45 minutes (!) until the
picture reaches maximum intensity and the picture stabilizes and color
saturation and the picture looks good like it should (clarity,color
etc.).
Is this amount of time for warmup normal? I put in a call for
servicing,but I am wondering if it is necessary as the picture is great
if you leave it on for HOURS.It almost makes me not want to shut it
off.Plus the fact,it does not always do this;just about a third of the
time.A defective
bulb maybe? Power supply problem? Or a "quirk" of DLP sets?

The flicker is not normal, you need a service call.

Could it be the set was on display for a period of time?? Sounds as if the
lamp or ballast may be having problems, normally the full brightness can be
realized within the first min of operation without noticeable brightness
flicker afterwards. As recommended, have it inspected by a qualified service
technician.

This is not normal behavior for a DLP. I have a Mits 73727, and it takes
about 30 sec. for it to reach full brightness.....

Yep. I have sumsung HL-R5067W (only 720p) and it is up and running at
full brightness in about 30 secs also.

My Mitsubishi 65732 takes about 20 seconds to warm up fully.

Ok,I discovered what was making my DLP TV
"flicker". I had a free standing motorized air cleaner operating in the
vicinity of the set within about 5 feet of it.When I shut it off,the
problem quit within 20 minutes.
I did not realize these DLP sets were so sensitive to electrical motors
and electrical fields in their vicinity.No CRT or the last lenticular
RPTV I owned did this.What is in a DLP that could make this that
susceptible?

Is it a high voltage electrostatic cleaner that ionizes the air? That
could certainly play havoc with electronics. A CRT RPTV is an
electronic dinosaur that _has_ high voltages in it so the designers
take that into account.

If the set has a dynamic iris, try changing the setting to "Off"
rather than "auto" or "dynamic." If the flicker stops it might
indicate that electrical noise was getting into the circuitry that
controls the iris.
