Question about Panasonic PT-47WX51 47" Rear Projection Television

1 Answer

What is the liquid under the lens

I get red ghosting on the right hand side of the screen and when I examined the lenses on the inside of the TV I noticed that the red has liquid under the lens that I can see "slosh around" where I cannot see that happen on the green and blue. What is the liquid and can I refill it?
Thanks!

The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,PioneerWhat is the liquid under the lens - 2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

GE 46GW947 TV. Screen is yellowed on top right corner with triangle shape a little less than full screen. Cleaned lenses and picture got clearer but still yellow on top right.


If you are able with the set on look into the three lens, what you are looking for is is there an visable liquid in any of the three lens on top?

These sets use a sealed area with Glycol, sometimes it leaks out so it is on top of the inside lens, DO NOT TRY TO REMOVE LENS COVER IF YOU SEE THIS.

I have a PTV916 Model # 60P8341A. I cleaned the lenses and the mirror inside the TV however, I can see alot of dust inside the actual lens. Is it possible to clean the inside of the lenses?


ll projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Mitsubishi wd 62527 has very dark picture changed


Clean the small front projection mirror. That mirror can get dust on it and will cause the projected image to appear dull and dim and cleaning that mirror will usually restore the brightness and crisp details in the image.

Does it take some type of gel under the lights, the colors are a little blurry


i also have this tv. i removed backcleaned mirrior, back of screen and lenses VERY GOOD. Then turned on tv go to convergence, sepaerate cross hairs then adjust focus on lenses. Then lenses rotate maybe about a 1/3 turn total by hand. Grab ring that houses lenses and turn until cross hairs are as clear as possible. This can be done with out help by watching inside of screen. red and green are adjustable, the blue is adjustablealso but i couldnt find blue cross hairs, maybe by covering red and green lenses the blue will show on screen. anyway when done and cross hairs are clear,lenses, mirror and screen are clean, you can adjust covergence and get a very clear screencleaning will also brighten pic.

I need to get the front panel off how do i do


Pull off the two speaker grills. They will seem like they are going to break but they'll snap out. You'll then see the 8 screws that hold the plastic lower facing in place. (4 on each side) Once you remove the facing, you can see the 4-6 screws that attach the screen assembly at the bottom of the screen. Once you've removed them, you simply place a hand along the left anf right edge of the screen assembly and pull up. This will pull the screen assembly off the plastice hooks inside the cabinet that hold the screen assy. in place. You can now clean the mirror and lens assys. You can use windex on the mirror but many projection TVs have plastic lenses so use a prepared solution from a video store or make your own with luke warm water and a couple drops of dish washing liquid. Don't get the lens too wet, so that water drips onto other parts of the TV.

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.

Colors bleeding, red tint around images


The liquid coolant between the guns and the lenses may be fogged, low, or both. If the red gun has fogged coolant, you'll see red fringing around objects. It can be drained and refilled with new coolant, but it's gotta be the right stuff. You may be able to get some from a junk set, as I have done with success. Shine a light into the front of each lens. If the liquid has gone bad, you'll be able to see it.

Blue ghosting on dark areas of screen


I think your son figured it out. check also to see if the liquid is cloudy or has any debris in it, if so it could use a change while you're at it. unless your son knows how to work on the TV(in addition to diagnosing the problem) you should have it looked at, with the advantage that now you know the problem, and what you're going to be charged for. to change the fluid, the only way to do it properly is to completely remove the CRT assembly from the set, drain it, disassemble it, clean it THOROUGHLY (I use a LOT of Windex to do it) and reassemble it paying close attention to get it together correctly. And don't forget to discharge that HV lead at the splitter blocks BEFORE doing anything else! The best way to put in the new fluid is from a squeeze bottle with a funnel shaped nozzle. A hair dying kit will have what you need, usually. you should make sure you're using the same type of liquid as was there originaly, because different liquids have different optic behavior. Have fun!
