Mitsubishi wd-73736 bulbs buzzing noise

I have a 14 month old 73in mitsubishi dlp tv. 3 months ago the lamp blew. Now for the last 2 weeks there has been a buzzing noise that sounds like an electric razor coming from where lamp was just put in. This afternoon I came home from work and now the lamp light is on again and the picture is gone! Is there any reason these lamps are going out so quickly?

The Ballast that ignites the Lamp could cause the Lamp to fail and/or cause a buzzing noise. That being said, the Color Wheel in the Optical Block assembly could also cause a similar symptom. If Mitsubishi would be willing to help with the Lamp cost, I would call a local Mitsubishi repair facility to install it and see if the noise is still there and find out exactly what is causing it. Mitsubishi Customer Service Phone number is 1800-332-2119.
I hope this helps,

Bulbs keep blowing


You may be touching the bulb (ampule) and leaving a fingerprint on it which creats a hot spot and blows the bulbs up prematurely.

My tv mitsubishi wd-60735 turns on for about 2 min. then shuts off and red lamp light turns on,,,The lamp is only 3 months old.. Do I just need to replace bulb again or is it something else???


Don't know if this applys to you but if you have purchased anything but Osram or Philips replacement lamp for your DLP tv then this is probably your problem.. The generic is VERY tempting in this recession but in this case generic is poison to your dlp tv... i have a Mitsubishi 60735 and went thru 2 generic bulbs when my tv kept shutting down on it's own and the lights on front would flash, i could cut it back on for 10 minutes then flicker and shut down again ..well since the bulb was new i thought it may be defective so i got is exchanged for another one ... after all of the post i have seen how much repairs were going to cost on dlp sets no matter what the problem was ..i was ready to chunk the tv out the door when the second lamp was doing the same thing.....!! well a last ditch effort to save my tv before i trashed it or taking it apart to dissect it.. was to buy a brandname lamp ... in my case i purchased a Philips ..it cost twice as much =/ ..i could just return it if it didn't work.. well it was the generic lamps that was causing trouble.. the brandname worked perfectly .. i am just glad the generic lamp didn't do any damage to my TV!!! I have done further research on the generic lamps and realized that the damage it could have done was not worth the money i saved when i purchesed it... Generic is a great deal In some cases (household cleaners, etc..) but in this case GET THE NAME BRAND!!!! the only name brands i know of for these lamps are Philips or Osram/Sylvania.. hope this helps others from this headache. Do your research don't by generic lamp replacements, your DLP set cost to much to risk it.

LAMP JUST WENT OUT


I have a 57" DLP and have replaced the bulb 3 times in 2&1/2 years. I'm not possitive but I think I have 6-800 hrs on it total. Mitsubishi claims it a part they expect to go out, but the told me they typically last about ten yrs. If you have proof of purchase they will send you a new one for free, otherwise it'll cost you about $150 on ebay.

Buzzing noise from Mitsubishi DLP WD-52327 after replacing bulb


Did your replace lamp come on the screen or did you lose picture? Just because the LED indicator suggest replace lamp it doesn't mean it needs it. If your pix was dull or loss of brightness then replace it, if not then just reset your lamp timer, check your owners manual for instructions.

the buzzing noise you are hearing is from the lamp ballast as it strikes the lamp. that is quite normal but it should only be momentary. it should not be constant.

Dead lamp!!!


is it tha lamp cracked? are you using original lamp from mits? i founded people using aftermarket lamps with other specks this lamp is 150 watts ,this info its going to help.
if components on the Power board K9A20 and/or K9A21 are shorted. Also, R9A02 may be open. Possible side effects are a deformed lamp exhaust duct and damaged lamp. Replace PWB-POWER part # 934C228003 and if necessary, Lamp part # 915P049010, Lamp Exhaust Duct part # 642B155010, and/or Lamp Exhaust Duct Cover part # 642B156010 let me know if you need anything else
