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.

    Someone else might suggest hat you Chang out the ballast, but definitely go bulb first. I changed out my ballast at one point with a similar problem and the problem was the bulb. I went through a replacement before ordering just the sylvania bulb. I replaced my bulb about 8 months ago now with no issues.

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.

usually with that model when you get a 34 eror code for lamp abnormality, its directly related to the capacitors on the Power Pwb. You can get the V26 Power PWB repair kit at the following link which repairs that issue. It contains the replacement High temp capacitors with the board location numbers and PWB identification as well as the service manual on CD. Heres the link its under their repair kit ctegory.

I also unplugged from the wall, and did the reset procedure. That worked a few times and then it didn't work anymore. Thanks for the help, just wanted to warn it may only work temporarily.

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.

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.

Heard a loud pop and now there is not picture


The first place to start is to remove the lamp and see if it looks ok. It sounds like the filament may have busted, which is common. How long has it been since it has been replaced?

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.
Regards.

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,
