SOURCE: Mitsubishi Projection TV WD-62525

I RECENTLY HAD A LAMP ISSUE THAT MAY ASSIST. I HAVE A MITSUBISHI WD-52525 52" DLP. I HAVE OWNED THE UNIT JUST OVE THREE YEARS. THE UNIT INDICATED THAT THE LAMP NEEDED TO BE REPLACED WHEN THE UNIT WAS TURNED ON. I ORDERED A LAMP AND BEFORE IT CAME IN THE UNIT QUIT WORKING. I REPLACED THE LAMP AND WHEN I POWERED UP THE UNIT I GOT A STEADY YELLOW INDICATION AND THEN A SOLID RED. MITSUBISHI TECH ADVICE STATED THAT I MAY HAVE BEEN SHIPPED A BAD REPLACEMENT LAMP. I SENT THE LAMP BACK AND ANOTHER WAS SENT TO ME. THAT LAMP ALSO GAVE THE SAME RESULTS. I CALLED CHUCKS ELECTRONIC REPAIR AND A VERY KNOWLEDGABLE TECHNICIAN RESPONDED TO MY HOME. IT WAS DISCOVERED THAT THE POWER SUPPLY BOARD WAS BAD AND THAT THE LAMP NEVER NEEDED TO BE REPLACED. I SPOKE WITH REPRESENTATIVES AT MITSUBISHI SEVERAL TIMES AND THIS WAS NEVER EXPLAINED TO BE A POSSIBITLY. THE TECHS AT MITUSBISHI BASICALLY JUST READ FROM THE OWNER MANUEL AND HAD NO IDEA WHAT THEY WERE DOING.

SOURCE: Mitsubishi WD-52525 52-inch DLP HDTV ywllow warning lamp light

that means your lamp it is getting to the end of its life.
sometimes even if the lamp still good the TV will send you that message because that timer is closed to 5000 hours

What you can do is open the lamp door, closed again and the tv will ask you if you replaced it the lamp, and just say yes and that sign will go away

or just simple replace the lamp. 915P020010

SOURCE: Mitsubishi WD-65733 no picture, electrical buzzes in series

What it sound's like is that the lamp ballast is the problem. Buzzing sounds like when the power is first brought to the ballast it has to ramp up the voltage to get the lamp to light, then the voltage drops back down when the lamp is lit. Sounds like the lamp ballast isn't ramping up the voltage the way it should. May have to replace it. A good service shop would be able to do this for you.

SOURCE: how to change lamp in mitsubishi wd 73733

Your TV is so-called V-36 chassis.
First shut off TV and unplug it from the wall.
On the back of the TV on the right hand side if look from behind you can locate plastic lamp cover that is removable. Behind the cover you will see lamp cartridge that held in place by screws that you have to loose using screwdriver. Remove lamp assembly and install the new one. Make sure that cartridge is all way in, you have to feel connection plug to be slide-in all the way. Tighten up screws but not too hard.
Reinstall lamp cover. Plug TV into the wall and wait for green LED light to stop blinking. Turn TV set on. It should display message "Power loss, did you replace the lamp?" You hit "enter" on your original Mitsubishi (not the cable box or Satellite box) remote control and this is it.

I installed new lamp comes on then goes off and I hear a buzzing sound. Could it be that it's not installed properly for get light to come on. I had to use different screws because the new lamp didn't


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.

Installed new lamp but her static sounds wd-73733 and still no picture


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.

I installed a new lamp and the tv is still blinking saying the lamp is bad. There is no picture.


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

My mitsubishi wd 73733 just made a popping sound and went off.when i tried to turn it back on its making noises with no picture goes from a green light to blinking red on lamp inicator do i need a bulb or...


You can actually go with just buying a bulb. I have seen many cases where televisions stopped displaying a picture due to a worn out bulb. The noise is also from the weak bulb.

TV will not power on, strange arcing and poping noise from rear


Even though the Lamp looks good it does not mean that it is. The only way to know is to relace it. If you have already replaced it with a Mitsubishi Lamp Assy. then the Ballast board would probably be the cause.
Hope this helps,
