Is this through the Mitsubishi factory warranty or through an extended warranty?

Mitsubishi's warranty. They contacted a local shop for repairs right away, but with the holidays and a "less-than-good" reputation from what I've read online about this place I'm not surprised, but what can I do? Mitsubishi went past the standard warranty to pay for repairs so I can't bitch too much.

Well I just had my 73842 for a little over a year. During that time I had the light engine replaced 3x. Now today, I get the 4 blinking red and 8 blinking yellow which apparently means the power board is ruined. Amazing.

Called Mitsubishi up and they want nothing to do with it obviously as i'm outside the warranty period.

Anyone know how much approximately to have this issue fixed?

That is a bummer. I've had my 92842 for a year without a single issue. I wonder if mitsubishi will replace the whole tv if there were enough issues in a short enough time. The reason for my post is that I recently checked the mitsubishi web site looking for the instruction manual and noticed that there was a software update procedure for the 92842. I have no idea when that came out and I can't seem to find any information about it. Does anyone know what it does? My tv has been great so I don't want to do anything to it that it doesn't need.

The xx842 model has the streaming apps. So the update is most likely something to do with those.

After they misdiagnosed the the problem and replaced the wrong part, I'm still waiting for the proper part to arrive. ::sigh::

The Light Engine was replaced today, TV powered-up.....YEA!

Now there is another problem, the image colors are way off! I adjusted the Index Delay (and a few other things) and that has helped some, but I have to turn the color control all the way down to watch it without hurting myself. Think old-school B&W television.

It's one of two boards, the tech will order both and swap them out together. I think the board that was swapped last month was faulty, but without being able to turn it on we couldn't tell. One of these months I'll have the TV back that I paid for....color and all.

I've got a 73742 that had the main board go out a few months after getting it a bit over a year ago.

Since then, on some few occasions about every 3 months or so, the set powers up to a fast blinking green light. The fix is to unplug it for a few minutes and then plug it back in. I know that isn't a real 'fix', but it is one of those problems a tech probably couldn't find unless it did it while testing. Fortunately for me, I bought a long extended warranty so at some point I'll be able to get it fixed right.

BTW, I'm now on month 15 or 16 with the original lamp. The set is run about 8 hours a day almost every day. That is a huge improvement in life compared to my old JVC HD-ILA, best it ever did was about 10 months on a lamp.

I have a 73742 and it looks like a moth has gotten inside the screen and died. Does anyone know if it's safely possible to clean them out and if so, how to go about getting it apart?

What do you mean inside the screen? Look inside the access holes on the sides and see if it's laying on the lens.

It's behind the plastic, like sandwiched. Not on the lens.

I have the wd-92a12 which seems to have the same parts as the WD-92742 except for the lens (not sure why the part is different). I'm currently running 14.03 and would like to have the perfect color/tint options and any other adjustment that's in the wd-92842 series to get the best picture possible.

Has anyone updated the firmware on their A12 or 742 using the 842 14.04 update? If so what were the results?

Also anyone have any info on editing the firmware? I've heard of people changing the DEMO picture, and the power off screen but really would like to see if it's possible to get the 842 adjustments under the ISF/ADJ display settings.

Thanks!

If you paid for the Mitsubishi TV with Amex or a Platinum MC or Visa, the credit card company will cover the second year warranty for free.

I have a WD-82742 that will turn on and power up but there is no picture displayed. The light in front is solid green like it should be but no picture. Do you think it could be a bad bulb? The manual says a bad bulb should be solid red light in front. I've tried reseating the bulb and a system rest wih no luck. frown.gif

Have you ever replaced the lamp? How many hours on the lamp? Everyone should have a spare lamp on hand.

Well the TV is only around 18 months old with estimated probably around 4000-5000 hours on the original bulb. I know I should have one on hand and have been considering ordering one recently. I just have a feeling a bulb will not fix this one.

Look at the back of the set. You should see a light shining through one of the ventilation grills if the lamp is working

If I had followed that rule with my 2007 Toshiba, I would still have a lamp sitting around seven years later. It's still on the original lamp.

Most of us replace the lamp before they go bad since they dim over time. Plus the fact if something does arise you keep the old as spare to troubleshoot and not be without a set if it is a lamp issue. 7 years doesn't mean much it's hours that count, I replace mine about every 5000 hours.

As long as I can still adjust the brightness when calibrating the set, then I will use the lamp. I've been using DLP sets since 2005. So far I've never needed to replace a lamp. Although Prior to my Mitsubishi I had an LED DLP set. I'll probably look into getting a bulb for my Mitsubishi this Summer. It will be 18 months old then. And I don't have much faith that the bulb will last as long in my Mitsubishi as my other Samsung and Toshiba DLP sets did.

Just to finish the saga...
The TV repair shop decided not to order more boards, but they did take the TV to their shop to re-calibrate everything that was lost after swapping the DM board. I'm glad I had something else to watch in the meantime! Several weeks pass, and I finally get the TV returned to me after I kept bugging them. The picture looks fantastic and the repairs didn't cost me anything ...thank you Mitsubishi. After more than 4 months this ordeal is history. Most of the parts have been replaced and I have a spare bulb waiting as well... so I should be good for a while. biggrin.gif

I'm leaving this here for anyone who may also be having an issue with flicker: while troubleshooting I originally didn't realize that the lamp's 'bright' mode was different than the 'Picture > Video > Picture Mode' settings. The lamp's 'bright' mode is located in 'Setup > Energy > Lamp Energy'.
