bulbs explode when they are not cooled properly. check your fans.

Your color is distorted because your color wheel is probably going bad. Try resetting all the picture values first. Sometimes they need to go back to normal when the lamp is changed. Lamps only provide white light and have no bearing on colors unless they are very dim. Also check your cables. a loose or bad cable can cause this as well. Lastly make sure your new lamp is made by Osram or Philips. knock offs wont work.

You have a bad power supply board. Check EBay or Shopjimmy to find a new board. You will need your model #. Which starts with WD-

You must use the factory remote. Mutlibrand will not work for this option. No matter the universal remote, you need the original. No other way to do this. 1. Press MENU on original remote only 2. Then press 2,4,7, and 0 3. Select "initialize" and then 'ENTer" This will full restore to factory original settings. but you need the original Mitsubishi remote.

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

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!!!
