most definately it is used to get a secure connection and eliminate all air pockets between the chip and the heat sink and with out it the chip will over heat and fail

Sounds like a misalignment problem. the lens has a specific optical plane the DLP chip must be positioned at in order to provide the proper focus on the screen. Try repositioning the board or adjusting the lens to clear up the fuzzy picture. Regards.

It sounds like either the controller is bad or the color wheel or scanning sync encoder is dirty or defective. One thing to try is to reset the controller program by unplugging the TV, wait two minutes, then power it ON. The micro-controller will reload it's program from flash memory (which takes several minutes). When the lights are all OFF, turn the set ON and see if the picture is correct. If you select the menu and the picture of the menu is stable, then the problem may be in the signal coming into the TV. Regards.

On your original TV remote look for button that says Picture size, Format or Ratio and press it till you see the normal size.

It is most likely that your light engine has gone out. When this happened to mine that was the part the service technician changed. http://www.tvserviceparts.com/WD73733.html

Check the lamp

I have had a similar problem and it has always been the bulb. If that doesn't fix it, then the ballast. Most likely your bulb is on the way out.

Could be bad conections, I gues. I have downloaded the service manual of: http://www.audiolabga.com/pdf/V36-V37-V38_Service_Manual.pdf In manual you can find more information about the problem. Luck! http://www.audiolabga.com/pdf/V36-V37-V38_Service_Manual.pdf

I would venture to guess the bulb figment is your issue and the electrical sound is most likely arching (very bad). The cheap replacements won't last. I bought a sylvania build and matched the model number with the one from inside the old bulb housing. Changing out the bulb from the casing is really easy so just return the one you bought and buy the corresponding bul without the case.

How do you know the solution is "simple"? No always is simple. Bussing is high voltage missing. Like is bad conection to the lamp. Check conections of it.There is some bad about the conections of lamp. I guess.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. Viewing it in "Mosaic" or "Magazine" will make surf easy. http://electronicshelponline.blogspot.com/ Blinking codes details to many popular brand TVs are given. Surf the site with patience. Do a search by type in the brand name of the device to the search box.

over heating ,faulty electronic parts

Go to Mitsubishi web site - load updated firmware as it will discuss, then load on the port at side or back of set

Kelly, The yellow blinking light generally means that the lamp cover is open. You may have accidentally jarred the lamp while changing the DMD chip, and the lamp safety switch is not engaging. The first thing I would try would be to re-install the lamp and make sure the cover is on correctly. Let us know if that solves the problems. Thanks.

who me

mirror tunnel has faded the mirrors need replacement then replace the lamp u need a new one

its most likely the ballast which is causing the issue. The ballast is what provides the power source to light the lamp. You can get the ballast at www.tvrepairworld.com and they can provide instructions on how to replace the ballast

Set has a soft reset but first:make sure speakers in set did not get switched off.Unplug set and or a box from power for several minutes and power backAlso check to see if audio with a DVD connected to one of the rear audio and video inputs.With the Mitsubishi remote Menu, 1,2,3 enter is the soft reset.

How do I remove the screen to remove bugs?
