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

How do you remove the headlight lense cover on a 2001 Century to be able to clean the inside surface?


You cannot remove the lense. it is factory sealed. only access inside is by removing bulb from rear of the lamp assembly. Your problem is probably a degraded hazy lense and not the inside. have lenses cleaned by a detailer or shop that can do a lense restoration.
Good luck

I have a 65 inch syntax brillian TV. The picture is pretty dark, and I'd like to clean the mirrors and lenses. How do I do that?


Shannon, cleaning the mirror or the lens will only drgrade the picture that's reflected onto the screen. A dark picture is most likely caused by the ~300 watt lamp aging and now needs replacement. You can confirm this for yourself by removing the lamp from behind the right hand speaker door and looking at the bulb-shape at the inside, bottom of the reflector. The bulb should be clear, with maybe a small white patch on the top of the inside of the electrod chamber. If it's a large white patch, or the chamber has any black, or even worse has a deformed chamber, the lamp only needs to be replaced.

I did the longevity testing for the 65" TV's. No other component caused the TV to 'darken' as you state....

A spider is on the inside of the screen. how do I open the tv open to get the spider out and clean the inside of screen and lenses?


go_n,
First gather your needed items: screwdriver and a helper.

The screen is mounted to the enclosure of the TV by hanging on tabs mounted on the enclosure inside behind the screen. The screen simply lifts off after removing it's set screws at the bottom of the screen behind the big plastic piece that is below the entire screen.

1) Remove the speaker covers (grills).
2) Locate and remove the screws that hold the plastic piece onto the enclosure (8-12).
3) Remove the plastic cover and you will see the set screws holding the screen.
4) Remove the screws (2-4).
5) Use your helper as your screen is really big for most average sized people and lift the screen including the plastic bezel up and away from the enclosure.

Ensure that you have a secure area to set the screen as it will be large, heavy but yet very delicate. Also, do not clean anything unless you know for sure that you need to as sometimes just by touching things they get misaligned or break. This means but is not limited to: mirror, lenses & the screen.

When reinstalling the screen ensure that you hang the screen back onto all of the tabs or the picture will be blurry.

Good Luck!

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 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.

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.
