Any suggestions? I've seen some mention of a ballast problem in my online research. That appears to be more than I care to bite off, but want to get feedback prior to calling for a service tech.

Thanks in advance...

I'd be willing to bet that you didn't buy the lamp from Mitsubishi. These lamps are not like light bulbs. They need to match the specs of your chassis model. Any aftermarket lamp you buy is a crap shoot as to compatibility with the TV, with many being cheaply made Chinese knockoffs. If the lamp is out of spec, the computer in the TV will fault out. Hopefully, it hasn't damaged your TV. Don't do anything until you replace the lamp with a genuine Mitsubishi lamp. https://mitsuparts.3diamonds.com/Pro...Model/WD-73840

Can anyone explain the red, blue and green high and low settings in advanced mode? I am sitting here for 1 hour and I can NOT find anything about this. This is ridiculous. I am so pissed I can't even explain it.
I have a calibration dvd and i want to mess around each color. There is no way to get the color right with blue filter. Flashing boxes will be either too dark or too bright if I just adjust the color setting itself

Can't use advanced mode effectively without a meter. Using the filters, shoot for something in between the two extremes. Doesn't the manual explain Perfect Color / Perfect Tint?

mitsubishi 82840

It feels like a longshot that there will still be people trolling this board now that these sets are dinosaurs in tv years. but i need some advice and this seems like it might be the only place that i can find answers without someone trying to sell me a ridiculously expensive repair job. this has probably already been covered somewhere else in this thread but there is way too many pages to read to find the answer.

i've been having a bit of flickering up in the corners during really bright scenes and commercials with a lot of blue in them. during start up my tv would make a sort of rattling squealing noise and sort of a pulsing that went along with the rhythm of the noise. which led me to believe it was a color wheel. then a couple weeks ago my set up and died on me. it won't power on i've tried to reset it and unplug it to no avail. it was flashing the code 6 red 1 yellow. i called mitsubishi and they told me that it is either the color wheel or the light engine. my wife wants me to get rid of it and frankly i think i'm ready to. its a pain to move and replacing the bulb is rather annoying (even though i only just put in my fourth bulb a couple months ago). should i sell it as is? repair it then sell? or repair and keep it?

i love the tv and honestly i don't think i could stand to look at anything smaller than an 82" and be satisfied. but at this point parts are starting to become scarce and very expensive. i'm fairly handy but have very limited and basic knowledge of electronic repair and i don't know if i could allow myself to fork over $500 to repair a tv that is so out of date.

any advice would be greatly appreciated. thank you for your time!

Haven't tried it myself but a buddy replaced his light engine years ago on a smaller Mitsubishi... he didn't seem to have much difficulty with the repair. These days finding the part might be the hardest part.

Might be cheaper and easier to go to an inexpensive projector and a DIY screen

I just sold my 73740 a couple weeks ago because I upgraded to a Sony 940D back in Decemeber. After having the 73740 on cragslist and Ebay for a couple months and dropping the price every couple weeks (started at $300), I ended up selling it for $175.

Point being, it is probably not worth it to you to put money into the set before selling as you will most likely not get it back. These old DLPs aren't worth much anymore apparently.
