Question about Mitsubishi WD-73733 73" HDTV
The new lamp doesn't fix as snug as the old lamp did. Same model part as old lamp but hearing electrical sounds now with new lamp when powered on but then goes right back off with red light coming back on.
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.

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.
