You can only wipe the exposed surfaces of the lamps. And i recommend a soft dry cloth. Do not go crazy here since in the end as long as there is no heavy coating it will not affect the image

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.

Picture only comes in sometimes

Yes the bulb when it gets old and dusty it heats up and shuts off, sometimes it remembers and wont turn on. Replace the bulb and clean out the dust from all fans.

Haze on area that the bulb faces.

If you can clean it and it comes off I would do it. This haze is caused by the extra heat the bulb was putting out before it blew. Make sure you blow/clean out all the dust you can. These TV's have a air intake filter also I believe. The more you can keep the filter clean and the Light Engine the better.

When i turn on tv i get a message that says air flow is blocked tv will shut down

It's probable that the inside of your Tv might be dusty, first of all i recommned you open the back of the TV and with a can of air (the one you can use to clean a computer) take off all the dust possible because the dust bunnies might be in the way, not letting the tv ventilate, if that does not work it might be that you have a defective fan which needs to be replaced

Mitsubishi WD-62527 replacement lamp install and brightness low

as i previously posted, my picture was dim, muddy looking after replacing lamp with osram lamp. i fixed mine by taking the screen off and cleaning the small mirror. it had a thick layer of dust on it, cleaned with a microfiber cloth. no water, no glass cleaners. i also used a very fine new small paint brush and dusted the projector lens which also had a dust film. brightness, contrast and clarity returned!

heat and dust are two major problems with this type of set.These set can get very dusty inside the optics and cause this type of discoloration .Heat can cause deteriation on optics and or optics cabinet parts .It is possible to clean the optics block for dust issues only but unless you know what your doing and know what areas not to touch inside optics block .Otherwise the block would have to be replaced..

Round shadows in picture

Sounds like the Bulb is almost out of life or a dustball or something is moving around inside the light compartment. Look in the instruction or user manual on replaceing bulb or opening bulb compartment or call Mits. for a service center in your area. Good Luck
