Top 20 Mitsubishi WD-73734 73" Television Questions & Answers

No TVs will behave that way due to a timer. TVs only will display a nag screen telling you to reset the timer. If your lamp is more than 2 years old, it is suspect of failure. Be sure you buy a lamp with an Osram brand or Philips brand bulb inside. Any compatible(knockoff)lamps will not perform as they should. Mitsubishi DLP TV Bulbs These folks sell original Osram bulbs in their lamps and they have a 6 month warranty. I use them myself for repairs and really have had great experiences with them.

Somehow--the lamp is not firing. Before you go get another bulb--check ALL of your work, and make SURE no connectors to the ballast have been left off or pinched somehow. It is easy to do this. Also, make sure the lamp door switch is making proper contact with the tab on the lamp door. You have already fixed a real problem with this set--do NOT give up so easily now!! ALso--make sure all fans are running. If ANY do not run--it WILL shut down. ANd make sure the color wheel connector has not come loose or been damaged somehow (this will be between the engine and the lamp area--likely have a "hump " raised in the light tunnel betwen the lamp and the engine--this is where the CW is). Even IF the ballast died (NOT likely at all), you can find one on ebay for under 100---and this set IS WORTH the repair. You will NOT be satisfied with some crappy flat-panel as a replacement.

Sounds like a light engine problem.

HelloThe Xbox 360 connects to a TV using either - COMPONENT (red blue green for video, red and white for audio - COMPOSITE (yellow for video, red and white for audio) - HDMISo, if your TV is on a "Channel", it is not on the correct input to view the Xbox 360. Check the Xbox and verify which cables it is using to connect to the TV. When you find this, follow the cable to the back of the TV and find the input selection. It should be listed as the type and a number (i.e. HDMI 2, COMPONENT 1). Have the Xbox on. Use the TV remote and use either the INPUT or the MENU options to change the input to the input that matches the port that the Xbox is connected to. This should make the Xbox work. When you are done with the Xbox, use the INPUT or MENU to change back to the tuner to watch TV.

This may help you if the set has the tiny recessed reset button on the front, those buttons (not the button itself but the tiny push switch under or behind it) do fail and trigger the set into the blinking green light of death--lots of techs call that.Somewhere behind the speaker grill is a access plate, removed you will see the bundle of wires that come from the front keyboard---there will be a inline plug----Disconnect it.Turn set on with remote--if it works the micro switch for the recessed reset button (its a joke as all it does is reboot the digital board) is bad---the remote will still work as the receiver is inside the screen unit. Leave it disconnected if the set works OR spend a few hours getting at the defective micro switch and remove it.If the switch is bad they only sell (if its available any more) the whole pc board with all the controls on it.

Seems like a dead pixel in the display. The only way to fix it is to buy a new screen which could be more than the TV itself or just buy a new tv.

Most of this is personal preference---if contrast (picture) is set too high the picture will have some smearing on dark or even very bright scenes--try to have that set at about 70% and brightness just a bit higher---a proper setting of the two will give a better picture with more clarity. Color and tint to preference and sharp to not full smooth (mid-range) Other than these signal provided accounts for clarity--pixels stopping etc is not the set but the signal provided not fast enough to keep up----cable and sat often jams a lot of info into a small space and that sort of issue results.If you have a HD quality Blue Ray compare it to your signal source and usually it will look much better.I have taken the time to cover as many bases here as possible.Hope it helps in some small way.SD TECH

Your tv is a DLP projection one. In it the image is generated by projecting light on a chip that is covered in tiny mirrors that reflect more or less the light towards the screen. In your case some of those tiny mirrors are no longer controlled - they are immobile and reflect fully the light so you get a white spot on the screen.The DMD chip that holds the mirrors is dying and you will have to replace it. This is the only place i could find that claims to have it on stock. You can also go thru Ebay, in there you will find second-hand ones extracted from defective tv's.It's installation is strictly a job for a person with great tv repair experience - too many thins can go wrong in there if the job is not done properly.

On the TV not the remote, simultaniously press the menu and input button for at least 5 seconds. This should give an error code. If it blinks 3 times then a pause then blinks 2 times, the code would be 32. Get your error code and look in the service book at: http://www.audiolabga.com/pdf/V36-V37-V38_Service_Manual.pdf -

Sine the TV's a rear projection DLP and the problem "grew" over time, perhaps those white spots are... DUST!!! Try a vacuum cleaner; there are ventilation holes/slots on the back and sides. If sucking and/or blow air into it moves the spots, then it's definitely dust or some other debris/contamination. If the contamination is hard to access, you may have to open it up to do liposuction.

You need to leave a lot more information than that.What is the background of replacing the lamp? Where is the clicking noise coming from? Is the lamp light flashing, etc.? My current best guess is that your ballast may be bad, but more info is always helpful in diagnosing a problem. Good luck.

You need a new dlp chip. The tiny Micro mirrors inside of it are getting stuck and there is no way of freeing them. You can either buy a new light engine which is very expensive or buy a new DLP chip and change it yourself. It takes about 30 minutes to do and is very easy. I have the DLP chip for $225 new. Other places will charge you about $345. [email protected]

This problems is the tv Projection Light Engine design flaw with it IC chip.These problems happen to many models of it DLP tvs Big Screen 60 and up.Mitsubishi,Samsung,Sony,Toshiba all used the same IC chip on their 60 and up on their DLP tvs Big Screen.Tries make deal with Mitsubishi help u split the cost of repair the tv Projection Light Engine by replacing the IC chip or replaced the entire Projection Light Engine system.This problems is not new,been going on for a few years.Many people when on Youtube **** about this problems with white dots showing up on their tvs screens and multiplying rapidly.

38 Lamp temperature abnormally high. Poor Air Circulation - found in service guide at - http://www.audiolabga.com/pdf/V36-V37-V38_Service_Manual.pdf

ok.. my first instinct for this problem is airflow... check to see if the filter is cloged or blocked...make sure the fan is blowing to cool it. if this all seems right then you might have what is called a faulty ballast. which may need replaced. or the fan might be jammeded.
