Dust inside tv

Hi, is it advisable to clean dust specks from the inside of one's television? Can you indicate the best procedure to employ? My warranty does not cover cleanings of any sort and I thought if it wasn't technically impossible to do so myself I would use an LCD cleaning kit to perform said wipe down - the dapped spots are annoying when an image has a light background, but is swallowed whole by any kind of texture. I have had the bulb replaced and a new light engine and religiously clean the filter but the dust problem persists (it was a display model and I probably should have cleaned the filter right away, but waited, rather stupidly, around 6 months into the purchase). Is there a way to avoid making this worse and still cleaning or is it necessary to call a tech - and if the latter scenario is recommended what will he or she do to ameliorate the problem (as in - will this cost an arm and an opposable thumb?). Thanks, Garland

There is some air cans that you can get on any computer store and try to blow out all the dust, then with a hand vacuum try to absorb it very carefully

Spot in tv


The spot may be from debris inside the chamber of the TV box. A bug, dust speck, or other material can attach to the inside screen or on a color tube inside of the unit. Do not touch the inside of the Front Screen as it has a special coating and you could damage the screen permanently. Avoid washing with water or sprays that can enter the frame of the screen. Use a cloth with cleaner applied to it and wipe clean, then dry with a soft rag or paper towel.

Mitsubishi TV, WD 60735; TV shuts off shortly after powering up.


It could be but a couple of other possible reasons---they had problems with this set and its brothers with caps in the main power supply puffing up and causing this "hard to turn on" issue.

A second reason is dust/dirt inside the unit.

All air is coming in via the front of the set and exits the rear--enough dust gets inside and the fans slow down or the lamp gets too hot and set shuts down---don't try this in the house: we take them with back cover off outside the building (on a ramp) and with air clean them out completely--try not to blow it inside the screen. It looks like a dust storm in most cases but can cause exactly the problem you have.

While replacing the lamp assembly is it better to replace the filter at the same time


Replacement might be a good idea, depending on the condition of the filter. The filter is there to keep dust out. Manny of the filters you can just clean with soap and water.

It is essential to keep the filter unclogged to allow air to circulate through the tv chassis to not only keep the electronics cooler, but also to keep your bulb running cooler and prolonging the life of the bulb.

That said, you should gently vacuum out the dust inside your tv that you can reach (tv unplugged) and make sure the fans are clean as well. I have used a soft paintbrush and vacuum to help clean out the insides of a TV filled with dust/dirt.

I have a Mitsubishi Projection Television WD-65736. It has been great, but suddenly after 2 years of use there are grey specks all over the screen when it is turned on. And now today there are bright white...


I think if you were to remove the top portion of the set and carefully vacuum the dust off the lenses on top of the crt's, that will fix your problem as it sounds like a layer of dust has settled on the optics.

Tv has sound but no picture.


Yes, dust is the number one cause to all electronics, i recommend using compressed air to clean the inside every month or so.

Same here...


Try cleaning off the dust inside the set.
Remove the back panel. Blow out the dust using compressed air.
Then vacuum.
Do not blow inside the fan on the right.

I have a RCA 60 inch TV and its about 12 or 13 years old. It has never been serviced or cleaned on the inside. The problem I'm having is the picture is starting to fade (quite a lot)and I was wondering if...


you probably have a little of both. the shutting off is definately heat related but could be too much dust on heatsinks, etc causing it to shutdown. cleaning may eliminate problem but could be a sign of an underlying issue..
the dust can really cause the picture to dim. most of these tvs you can pull the "lightbox" or guts out of the cabinet to clean all 3 lenses, and clean the mirror if needed. don't mess with the screens except cleaning the front from outside. usually a 1/4" driver will be all you need, and a soft cloth for the lenses. use compressed air or a vacuum to clean out dust which will help with cooling, but the picture is only effected by dust on lenses, mirror, and screens.

Spots on the screen


The dust is on the lcd located inside the optical block. It requires quite an extensive tear down and if you're not at the minimum a CET don't attempt this one yourself... Most shops won't even do this cleaning in the home and any repuatble shop that does it has a clean room they will put it in to do the work..
A single speck of dust no larger than 25 microns on the lcd can shadow in the picture. To give you some idea how small that is a blood cell is 7 microns wide...

Mirror


There is black insulating foam that surrounds the projector and it may be displaced to one side.This leaves about an 1 inch opening around the projector lens and that could be the source of the problem,dust being blown into the compartment with the mirrors.
Cleaned the mirrors really well and used double stick tape to reattach the foam to the plastic frame and this will closed off the opening that maybe letting the dust into the mirrored area of the TV.
