Call repairs and get em out there. You might want to get video of the TV doing it cause I had a hell of a time getting them to do anything for me because when the tech would come out the TV would never do it so if he did not see it then he could not diagnose and or confirm the issue. So I had to record and send a copy of it to some higher ups to get anything replaced. You also might want to take a look at your lamp. I got mine in Sept 2010 and had to replace the lamp in June 2011 because it failed. There was a bubble at the base of the bulb.( link to pics of the bulb http://www.avsforum.com/avs-vb/showt...3#post20488123
) Now my TV is getting dim again which is a symptom of the lamp failing again. It's not completely failed yet but its going the same direction as the original lamp.
Another issue some people had with these sets is the HDMI handshake issue. When switching from one hdmi to another hdmi source sometimes the screen would remain blue and you would have to unplug or soft reset the tv by holding the power button for X amount of seconds.
Fix for flicker is Light engine
Fix for tv looking like its getting dimmer. Lamp replacement
Fix for HDMI issue is the Main board.
all of which have been replaced on mine about 6 -8 months ago.
An I am now having the flicker again and the dimming lamp again. The HDMI handshake issue is coming back as well but not as bad as the first time. I can fix the handshake issue but scrollingand going into each input once.
I know that's prob more than you needed to know but just an FYI you are going to have issues with these sets. if not now then later and if not later then you got lucky. lol
one more thing my 73733 has dead pixels (only way i can describe it)or white and black speckles all over the place on the screen. Which is also a light engine fix. I can only expect my 82738 to follow the same path as my 73733.
I'm done with Mitsubish. Having a big TV is no good when you cant get it to function properly. Doesnt make you want to watch it when it flickers and dims and malfunctions. I know all TV's have issues but my 73733 was replaced about 3 times and still has issues after repairs. My 82738 had issues out of the box and still does after being repaired a number of times.
Anyway sorry for the rant . Get your light engine replaced and you should be good for a little bit till its time to replace it again.
