Hello, did you touch the face of the lamp? If you did, you will need to clean it off to remove your prints. The next thing is, the fans may not be working properly and not cooling the lamp and light engine properly. Let me know....tks

have you cleaned the lens & mirror? you can access those by removing one or both the porthole covers. There is a porthole cover on each side of the unit (left & right ) of the screen.

you don't have an HDMI input on this unit & will need to use the component input.

I think this is a DLP tv and has a special fan deep inside the works. I think, not sure, but you can google around to find more information that error code 42 is that fan having failed or disconnected somehow.

You must follow instructions very carefully when replacing the lamp. Chances are the door did not get shut tightly allowing an open circuit to the door switch and the fan. If the fan is not running you must go back and make sure the lamp installation is right. also, if you did not purchase an exact replacement lamp it may be defective. If the fan is running then the chance is for a bad lamp. Hope this helps.

It usually means big trouble. But first turn the set off, unplug the power cord for a couple of hours and then try again. If still blinking, count the number of blinks and google for Mitsubishi blinking code. You can look for specific information and troubleshooting with the model number found on the back of the set.

Sounds like the Power Board Switch is bad. Anew one is a bit expensive to purchase.

Hello, it sounds like your color wheel is going bad. the humming noise is usually the bearing in it going bad and it starts to distort the image and finally it will shut the set down because it is malfunctioning......tks

have you replaced the lamp?

that's sounds like a Mitsubishi projection tv get a new bulb that's what ya need they are mercury so be careful, and another thing make sure all screws are put back in tight safety features will stop tv from staying on or sometimes powering if just one screw is not put back in in the bulb area and on the front just saved you 100.00 bucks

If the old lamp still works, I would try it and check results... it may be dim, but if the dark bar is gone then the new lamp (or the lamp housing) is either defective or misaligned. On the Mitsu WD65736 there are two options for lamp replacement, either (1) you can just replace the lamp itself or (2) for just a few dollars more you can obtain a complete lamp cartridge (module) with the lamp already installed. I recommend the latter method because you must not *ever* touch the lamp bulb with your bare fingers, as to do so will significantly shorten the life of the new lamp. Also try pulling out the lamp module and inspect it as well as where it plugs in on the back of the TV. Why did you change the chip? If you got the replacement chip the legal way (direct from Mitsubishi parts) I would get on the phone with them. Mitsu generally won't send out a replacement flash chip unless you open a repair ticket with them for a known/documented problem for which they have a patch. Note well that they will otherwise *NOT* give you the latest firmware without a reason. Simply wanting to have the latest & greatest is not considered a valid reason. On the other hand, if someone shared their flash ram with you and you burned your own chip, then you are on your own. Just the act of inserting the new chip will cause it to download the new image from the chip and then automatically erase the chip Hopefully you backed up your original flash chip and can go back to the original firmware. FWIW, the **only** Mitsu firmware patch I'm aware of for this particular model had something to do with being unable to pair it with a cable card. If all else fails, there is a very extensive (thousands of posts) on AVSFORUM dot com for the Mitsubishi WD series. Search for your model. One of the posters there even did a full documentation along with pictures showing how to disassemble & clean the lense assy. Don't bother asking for firmware there as it is a violation of avs forum board ethics for any member to post links to or share copyrighted firmware. Good luck!!!

these white spots are caused by a bad DMD chip call Mitsubishi and they will find a servicer and send the part to them for repair. You will only have to pay the labor

Does the satellite receiver power up? Usually they go through a test sequence when trying to reconnect, i.e., there is some picture output to the TV even when a satellite is unavailable. Did the input on the TV get changed? Try cycling through all the inputs. Do you have any other video devices, like a BlueRay or DVD player? Do they work? Divide and conquer, figure out what does work, then look deeper into what does not.

Set it to default. Color temperature has no effect with the wattage output to its bulb. Electro help

Put it back to the mid point of it's adjustment range. If the V hold won't stop the picture rolling at some point in its adjustment range then the circuit that it affects has drifted out of tolerance. The defective parts in that circuit need to be replaced..
