Question about Mitsubishi WD-73827 73" HDTV DLP TV

1 Answer

I replaced 3 times the lamp within a 4-6 month period. and today tech and I found and smelled burn odor and found the plastic black cover Melted down to have caused a major fire hazard if I had not contacted the tech in time. he has determined blastis parts and cable parts plus lamp plus cover will require replacement and then at that point he will need to check if fans (2) are functioning.... This is not good at all..... If Techs have replaced 2 other times, why did those techs not find what today's tech did?

Ballast to lamp connection cable melted on one side


The Ballast plug melted due to age of the TV. as the plastic gets old it gets brittle and can crack with barely any force. The pins then do not seat and the arc that should be in the lamp takes place in the connector. I have seen this so many times. fortunately it is very easy to replace the connector is you know how to use wire crimps and can source an old female plug. eBay is a good source. you can buy a used ballast from any model that has the same connector. Then cut off the new plug and splice it onto your old wires with but-crimps and shrink tubing.

My scooter is sbeeping 5 times what is the problem


There are several solutions to this problem.
The scooter may be in freewheel mode. The easy solution to this problem is to work the brake lever back into drive mode.
The brake may be shorted or open. I have seen these brakes burn out due to a dragging brake on several occasions. If caught early, the brake can be replaced without causing damage to the wiring or the brake interface harness to the controller. I have seen the brake burn out and melt the interface harness up to the controller connection.
With a digital voltmeter the brake can be tested at the 4 pin molex plug for resistance. This procedure is simple for a qualified technician.
The brake should cost about $100 and the interface harness about $30 so there some savings of the labor charge if you do a self diagnosis by inspecting the wiring and brake. The brake will be discolored, the release lever will be difficult to work, it will smell burnt and the wiring will look melted, Four screws hold the brake on the end of the motor and there is one plug. The interface harness has 2 plugs. 4 screws hold the main rear plastic cover of the scooter and there 4 screws to remove the metal cover of the controller. Less than 1 hour for an experienced tech.
In the rare case of the controller burning out also, retail is about $400.
Please check for your warranty details before spending any money on this repair. Most of these I have done have been within the warranty period. Hope this helps.

What is causing an odd smell in the refrigerator side of our side by side?


Due to open storage of Vegitables & NonVeg items produces gasses in refrigirator this will attracts the water and to other food products and may give bad smell. For this aspossible place them in plastic bags / in airtight containers. To reduse the smell in the refrigirator follow these guidelines.
6 Easy Tips:
Keeping your refrigerator in tip top shape and those odors at bay has never been so easy. The first thing I usually do after detecting an odd odor is to remove all the left over food that may be stored. Even if some of the food was just put in for keeping, it may also have absorbed some of the odor itself. And I don't think I'd want to keep it if it is. So the best way to start is by making sure all leftover food is cleared out. And then follow up with the 6 easy steps below for keeping your refrigerator smelling fresh and clean.
1. On a monthly basis, wipe the insides of your refrigerator out with a solution of white vinegar and water. It is said to work best if you heat the solution up in the microwave for approximately 45 seconds. Be extra careful when dealing with any heated liquids to avoid burns.
2. As an alternative to vinegar and water, you may also try wiping the insides of your refrigerator out with a mixture of half chlorine and half water. This method has also been proven to cut down on any mold you may see from time to time around the rubber seal of the refrigerator doors.
3. Ok, this next tip may sound very odd. But it is said to be really a tough smell catcher. Take a bowl and fill it with cat litter. Any kind will work except the clay kind. Place the bowl in your refrigerator and shut the door. After about three days, your refrigerator should be back to smelling nice and clean.
4. Charcoal is another great unexpected item you can use to absorb those fowl smells. Place a few chunks on a paper towel or cloth and place it in the back of your refrigerator. And within 24 hours you should be able to detect a huge difference.
5. Another very inexpensive idea is to place a cotton ball saturated with vanilla extract inside your refrigerator. Place a couple around if the bad smell is very noticeable. And apply more extract as need.
6. And my last tip is a very well known method. It is placing a box of opened baking soda (found at any local supermarket for around $.59) in the back of your refrigerator on the bottom shelf. It will also absorb foul odors and give your refrigerator a fresh clean smell. You can replace the box when needed, which will probably be about every 3 months.

It smells like something is burning smells like the gas is not burning very harsh odor that burns your eyes after a period of time


If it smells like an incomplete combustion smell, clean the burner first. I'm assuming it used to work and now doesn't? If it never worked correctly it may have the wrong jet in it. There is a jet for propane and one for natural gas. They do not interchange. If it smells like plastic burning, something probably got past the screen and fell into the burner.

Probably the odor from the new lamp. It should disappear shortly.

Burning out lamps on my 65inch dlp


I have 65" Mits. lamp lasted about 2+ years and burned out. bought new on internet, that lasted about 5 months and went. Got free replacement and that lasted about 4 months. No more free replacements ...

Bought new from different source and it burned out in a week.

Note: These were ALL OSRAM original lamps from reputable suppliers.

They sent a new one but also cautioned about cleaning the "filter" on the lamp housing. NOT the large screens on either side, but the small rectangular one (about 3/4" x 2"). I did this with a shop vac pulling and pushing from every angle and it was really clogged almost solid. No way air was going across the bulb to cool it.

THIS IS CRUCIAL and I feel is the keys to the kingdom! I did this and voila - no more "plastic smell" when installing the new lamp and everything's great!

I feel that Mits should be held accountable for this for not recommending the lamp housing be cleaned periodically (maybe yearly). I really feel if this were done with my original one it would have last a lot longer.

Burning smell from AC Unit


http://www.hannabery.com/faq14.shtml

"Odor problems can be as serious as a gas leak or as simple as a dirty air filter. But remember, a good mechanic doesn't just use his hands. He uses his ears and nose. Unusual odors could indicate a serious problem and should not be ignored. 

We will go through each of the five categories and list the possible causes and things to check.


1. Electrical odor - Electrical odors are usually caused by parts overheating. Indoor blower motors are a common example. If there is a mechanical failure such as the bearings seizing up, the motor over-heats and the insulation on the wires and the motor windings themselves start to melt, causing the odor. 
Sometimes loose electrical connections cause wires or plastic relays to overheat causing electrical odors. 

It is possible for a very dirty air filter to cause the odor. If the airflow is restricted enough, it could cause electric resistance heaters to overheat, even burn-out. 

If you smell an electrical odor, check your air filter. If it is not blocked, shut off equipment at the breaker if possible and call for service. 


2. Burning odor - This is similar to an electrical odor only worse. It is also sometimes accompanied by smoke. Once again, this can be caused by parts or wiring burning-up. 

It can also be debri such as plastic getting into the ductwork and melting on the electric resistance heaters or heat exchanger. 

If you smell a burning odor, check your air filter. If it is not blocked, shut off equipment at the breaker if possible and call for service.



3. Gas odor - First of all, if you really smell gas and suspect a gas leak, you should open the windows, get out of the house, then call the gas company. 

Now excluding that "worse-case" scenario, if you notice an odor that smells like gas and it seems to be coming out of the supply vents, it usually isn't gas. Sometimes dust that settles on the heat exchanger during the summer months burns off at the beginning of each heating season and it smell just like gas. 

If the odor doesn't seem to be coming from the vents, try to pinpoint where the smell is coming from. Use your nose. If it is gas, it usually would be from a leak in a pipe fitting or at the equipment itself. 

Gas odor is the one that causes the most fear. People think of gas explosions or carbon-monoxide poisoning. Well, gas explosions are very rare and carbon-monoxide for the most part is odorless. 

Having said that though, don't take a gas odor lightly. If you can't locate the source of the odor and you are worried you have a gas leak, remember, open the windows, get out of the house, then call the gas company. 


4. Oil odor - Oil odors are usually caused by one of two things. An oil leak/drip or an oil burner that is not working properly. 

The oil leak is usually easy to spot. Just look for oil. Check the burner itself, the oil tank, filter and oil line. Sometimes it is just a matter of tightening a fitting. If there are no signs of an oil leak then it is most likely a burner problem. 

This can be caused by many things, too many to list. It could be a minor adjustment to the burner to a faulty or blocked chimney. From a bad fuel pump to a plugged oil nozzle. Listen for any unusual rumbling or banging sounds or smoke or soot while the burner is running. If you notice any of these things and/or you have an oil odor, you should call for service immediately. 

One other common problem today is that new houses are insulated so well and are built so tight that they run out of combustion air, causing odor problems. In this case it is just a matter of bringing in a fresh air for the burner. Call your local Heating Company to assist in a proper diagnosis. 


5. Damp and musty odor - This is more common in the air conditioning mode. Sometimes attic units or very damp basements have this problem. Check for air leaks in the return ducts. Check for water damage to the ducts or air handler itself. Possibly consider having your ducts cleaned. Run a dehumidifier and see if the odor goes away. 

But this odor problem is almost never due to a problem with your equipment. 

 


Final Tips:

Keep in mind that almost all heating systems cause an odor the first time they are fired-up. And the first few times at the beginning of each heating season. Brand new furnaces are coated with oil to keep the heat exchangers from rusting. This burns off, creating a bad odor - even smoke. But it usually only lasts for about 20 minutes. Opening the windows usually solves the problem. And the first few times the backup heat on a heat pump kicks on, it smells like an electrical smell. This might last for a few days but isn't that bad. If you are worried, call for service. 

Remember to check for a clean air filter and that your vents are opened. Check to see if the fan is working which mean your motor hasn't burned-up. 

Check for air leaks in damp areas, oil stains or rumbling sounds, strong gas odors - these all indicate problems. Do not ignore them. 

Hope this helps, remember - these are just rough guidelines and not all possible situations are covered."

Burning plastic smell INSIDE refrigerator


look for a door/light switch, and depress it do the lights go out?? bad switch will keep the lights on and melt plastic lens covers.. could also be nothing and you happened to open open the door right as a defrost cycle was completing( there is a heating elemnt in your freezer) watch your dairy, ice cream nad milk are real good indicators of refrigeration issues. as far as runnig all the time no real" time limit" as to how long it should be running.
