Question about Toshiba 55H70 55" Rear Projection Television

1 Answer

Removing the speaker screen.

I would like to take the speaker screen off and clean the lenses in the inside because our TV had sit in our shop for several months while we were moving. I know it would have a much nicer picture if I could wipe off the lenses. I'm sure it's loaded with dust. Does the speaker screen just pop off? I don't want to pull it and break it. But, it's very costly to have someone come out to do a cleaning.

You can not clean the lenses by taking off the speaker screen...you can do it by taking off the back panel and polish your lenses that way please make sure you unplug your tv first

We have a red and green light shining through the screen. You can only notice it when the background is white.


You may need to clean the projection lenses (all 3). They can usually be accessed by removing the rear cover and removing the light deflection plate (it just keeps light from leaking out of the TV into the area behind your TV). Dirty lenses scatter the light and cause dim, washed out images. Clean them with a soft dry cloth to remove the dust, but do not scrub. Once the free dust is removed, lightly moisten a soft cloth with dish water and continue cleaning the lenes. Dry and polish lightly with a soft cloth.

The colors are separating


If you haven't used the autoconvegence option in the menu screen try that. If not clean the projection lenses inside the TV with qtips and alchohol with the tv on so you can see if the lenses are clean.

Screen bows in and picture has double images color around images id weird you can see the picture but everything is blured


I fixed mine by cleaning the projection lenses by removing the speaker cover, then removing the button peice.
There are 2 screws on the back on both sides and I think 3 in the front that need to come out. They are an allen key type 7/64". The button peice should pull forward and drop down.
Now you should be able to see the projectors. I used q-tips and alcohol to clean the dustr off of them. (I went over them with the power on so i could see if there was any streaking.)
After the lenses have been cleaned you should go to the auto convergence function in the setup menu.
You should have an awesome picture! Enjoy.

The blue will not converge, how can I manually do it? The blue appears to be showing bottom left corner below the screen, like it got moved.


I had the same problem but it wouldn't converge on the whole right side of the screen. I fixed my problem by taking off the speaker cover, removing the 3 allen 7/64" screws from the front of the bottom of the button pannel, then removing the 4 scew from the back of the pannel (2 on each side), and the button pannel should drop down. With the power on I cleaned the 3 projection lenses with many qtips dipped in alcohol. I left the TV on so I could see if there was any streaking on the lenses (streaking means it is still dirty). Once they were all clean and I put the button pannel back on, I went to the menu and ran the autoconvergence function. Now my picture is so clean. Good Luck.

It has a spider web inside the screen and I need to know how to clean it because it is directly in the center of the screen


The best way to get at it is through removal of the front screen. Start by removing the front speaker grill-should just pull off (snap fitted). Then remove the front control panel (4screws). Next remove 4 screws from bottom of front of screen- the screen should ten just pull off -also snap fit- Make sure the set is unplugged before you begin- Once the screen is off you can also clean the lenses and the mirror (if glass) use a soft damp cloth.

Looks like I have a couple of flys on the inside of the screen


Dont even think of removing the screen.....virtually impossible to reinstall. If you must clean...clean the picture tubes. Blow the dust off the lenses with air spray, then spray a lint free cloth with a lcd, plasma cleaner. Try not to use windex. [leaves a film on plastic lens] . Now pay close attention because the mirror you try to clean is a reflective plastic sheet that can tear easily. Lightly brush a new feather duster on this. Now you can only do this by removing the lower back cover [a hard cardboard material] and dislocate your elbo to clean . You can clean the inside of screen with the feather duster, donot use a cleaner inside the screen or mirror. Relocate the old elbo and replce the lower back cover.

Cleaning the bulbs and mirror on my Mitsubishi 55" WS-55313 TV.


You should re-consider having a tech do that for you. The access is by removing the screen assmbly which are somewhat fragile. If you want to give it a try, pull the speaker grill off, it comes off just from pulling it, there should be five screws across the bottom of the screen assy, remove those, there is also an access door on the front of the set with four screws, that has to be removed to unplug the cable that goes to the screen sensors. The screen assy has to be lifted straight up an inch or two and then you can pull it forward away from the set.
As far as cleaning the mirror and lenses, you can't get to the face of the tubes so it's the top of the lenses that you clean, just use a soft lint free cloth (cloth baby diaper) and wipe the dust off the lenses, you can slightly dampen the cloth with water if necessary, same type of cloth on the mirror and you can use a glass cleaner on it just don't press too hard on the mirror.

Screen is dim and not very bright


You can safely clean the mirror and lenses, it can greatly increase your picture if its dirty. If you unplug your tv you can safely remove the back and gain access to the lenses. All it takes is a philips screwdriver. After you remove the back, you can remove the light barrier between the upper and lower half to free up some room. Take a dry scratch-free cloth and wipe the dust from the lenses. If they're grimy, use a little lens cleaner (liquids used sparingly here, electronics don't like liquids, be careful) You can look up into the top and see if the mirror is dirty. A flashlight shined on it will illuminate the dust/dirt if its there. If you don't smoke you likely won't need to clean the mirror, but it may need it. Use windex or similar for tough grime.. I can usually reach up to get the whole mirror but I've heard of using a swiffer mop to reach the top. Removing the screen is difficult but possible if needed to get inside. Don't touch the back of the screen but lightly with a rag to get cobwebs, etc.
