Question about Panasonic PT-61HX40 61" Rear Projection Television

1 Answer

Clean inside of the screen? Spider webs?

Is it possible for spider webs to get behind the screen on the pt-61hx40? We can see several thin wavy lines on our screen and they are not scratches or cracks, nor are they on the outside of the screen. Is there a way to remove the screen and clean behind it?

    Before I even attempt it, I wanted to know if it was possible or if there was something seriously wrong with the screen. Thanks for the advice though.

    I don't have thin lines I have a few dark streaks. It might be from heavy smoking in the room it is in...I but I would like to find a way to clean it.

Scratched plastic screen protector

I have a rear projection TV that I thought had a scratch as well. Upon closer examination and several attempts to clean, I discovered that there was a spider web behind the screan in front of the color projectors. I carefully removed the screen and gently cleaned the spider web from the screen. Presto no more scratches.

Hope this is a viable solution for you as well.

How do I dust inside the screen of a Rear projection TV?

Unplug tv first Usually you can pop the front screen off the set. There may be two hidden catches depending on the model. You may want to use two people for this. Once the screen is off removed the spider web and clean the back mirror with some windex, don't clean the inside of screen with any cleaner. Replace carefully the screen making sure it clicks back correctly

Hitachi 51UWX20B spider web like lines help

I know my response is a while after you asked, but to clean the inside of the tv case is pretty simple.

Remove the bottom speaker cover...on this model you just pull it off. There is no clips or screws.

Once the speaker cover is off you will see the bottom of the screen, there is 4-5 screws on the bottom on each side....I think 4 in the gray plastic and 1 in a black metal strap. With all of those screws out pull out SLIGHTLY on the screen and push up. The top is held in with a down force clamp and you are just popping it out of that....It will pop back in once you are done.

Now clean the back side of the screen, the mirror and CAREFULLY dust off the lenses. I myself did not want to use any cleaners (to avoid streaking) so I used a new microfiber dusting cloth. My picture became brighter and the "crack" that I thought I had was just a dust web....

Hope this helps and good luck

Dirty screen but it is behind the outside screen.

The front screen with the frame does remove from the cabinet giving you access to the mirror and CRT lens. Remove the speaker grill,remove the four screws on the bottom of the frame, then working underneath a corner proceed to pop the rivets holding the frame to the cabinet. It will seem impossible at first because you have to use a lot of force to pop each one out.When reinstalling,a rubber mallet may help popping each rivet back in (I am not kidding when I say they are tight)

Spiderwebs under Screen, how do i clean it ?

Yes, I have seen this many times. Usually the best way is to remove the upper back cover and clean out the spider webs with a soft, dry cloth, but be careful because the mirror is mounted to the inside of the cover.

Trying To Remove Screen

I have a panasonic 53 inch and have had the same problem on numerous occasions. I removed the backing of the television, stuck my vaccuum cleaner hose inside the tv and sucked out the spider and the web.

Sider webs

Here's my suggestion: I have a 55" Philips HDTV and I live in an area known for excessive dust and more than a fair share of spiders. I checked online and found that there are usually 1-4 access panels that can be removed for cleaning, repair, etc. Here are my steps: 1. Remove the upper most panel (usually a trapezoid-shaped plastic "box"). There are anywhere from 1-4 "hangers" that, once all the screws are removed, will hold the panel in place while you are unscrewing the last few screws. 2. Remove the panel and clean with a lint-free cloth the entire inside of the panel. This is an area where a lot of dust and spider webs can be found. 3. Grab your vacuum cleaner and carefully clean away all the spider webs. Making sure you don't bump into the inside of the projector screen! 4. Spray a small amount of dust cleaner or window cleaner on the lint-free cloth and run the entire length of the TV. Clean all surfaces this way except the reflector (mirror). It is best to clean the mirror with compressed air (get it anywhere - usually in the computer section). 5. Using a flashlight or bare lightbulb, thoroughly inspect all surfaces for dust and spiderwebs. And, of course, clean anything missed the first time around. 6. Using a clean lint-free cloth (I find cotton underwear from Wal-Mart works the best), spray a very small amount of window cleaner (streak-free Windex, etc.) on the cloth and rub the cloth together until almost dry. Then, simply wipe all three lenses clean. 7. Replace the back panel and pay close attention to the alignment of the holes to ensure the screw goes back in the same way it came (if not, the panel could ultimately lose the seal and allow for more dust). 8. Allow for several minutes drying time before turning the set back on. Hints: 1. Clean the speaker area, too. 2. Repeat the process at least each 30 - 45 days to ensure optimal performance. 3. Use a small computer fan to circulate air behind the set if the area gathers excessive dust. They're quiet and can be purchased (almost anywhere - Radio Shack, Wal-Mart, etc.)with switches that are easily accessible.
