Your TV most likely has a convergence problem.

  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

57h94 hd tv,need to clean picture tube


Hello, first you have to uplug the tv, then remove the speaker grill (I think that one just pulls off the front, but some models had 2 screws on each side on the rear edge of the cabinet) once the grill is removed you will see either 4 or 6 phillips head screws along the bottom of the screen frame, remove them and unplug the control panel plug (may be 2 plugs). when that is done raise the screen assembly straight upwards about 2or 3 inches and pull straight out and carefully set aside. Use a quality glass cleaner and a lint free towel's, spray the towel with the cleaner and wipe the lens of the 3 crt's that face the mirror and dry them with a clean towel. Then clean the mirror the same way, do not spray the mirror with the cleaner. when everything is clean, replace the screen by holding it against the front of the set but about 3 inches above the top, press it gently inward on the frame as you press it downward until it is flush with the top of the cabinet, check to make sure it is flush with the sides of the cabinet all the way down, if not re-raise the screen and lower it making sure that it's flush on both sides. Re-plug the control panel , and re-install the screws and the speaker cover,,,,,tks

I have a magnavox 55 inch screen model nu is 6p5440w102. Picture is dark tried to lighten but wont brighten up anymore.


This is an older set------with back off you will see 3 large black cylinders with lens---these are the red, green and blue picture tubes.

Clean the lens with a lens cloth or paper towel with glass cleaner sprayed on the towel.

Annual cleaning of them is suggested as dust or dirty lens will cut down the brightness---this happens gradually over time and will make the picture darker and somewhat dull looking.

I do it with set on but you should UNPLUG SET and just look to see if dust on lens.

Simple and takes only a few minutes.

Let me know what happens.

Tmtmail.co.ukmy samsung projection tv has double vision and i dont know how to amend the lens can yu please help thank you


double vision in a rear projection tv has several reasons. one is convergence magnets are out of tune. u need to tune them which is back side of picture tubes. u please observe that which color is producing the double vision. the lens are firmly fixed & therefore need not to adjust. other option is to adjust the convergence of tv by going to service mode by remote.

JVC 48 inch rear projection tv with 2 spot in center of screen. one is blue/green the other is yellow. ther are stationary and appear only when the tv is on. Looks like someone used crayons on the screen...


yes, I know what is wrong and there is a simple way for you to confirm this.

Have you ever seen a TV with just a white line across the screen from left to right? On a regular TV if this happens and you leave it on long enough it will burn the mark into the screen.

I suspect what you have is two of the picture tubes in this projection TV have a burn--it is caused because the set lost either horizontal or vertical sweep--picture either closed from left/right or top to bottom for a moment and then came back on instantly---burns a mark in one or more of the 3 tubes screens.

Way to confirm is simple--with the back cover removed cover each lens one at a time with the set turned on--be very careful when you do this not to touch anything else---

if you cover a lens and one of the marks goes away that tube is burnt----my guess is you are going to find at least 2 of the 3 tubes are burnt on the screen---

Problem here is the tube or tubes need to be replaced to correct this AND whatever caused this HAS TO BE FOUND ALSO OR IT WILL DO THE SAME THING TO THE NEW TUBES--


CONSIDERING the cost of two or more replacement tubes you are most likely better to buy a new TV---I have seen about 100 sets with just exactly what your are describing---It does not happen a lot--but once it happens the damage is permanent.

I know I am not giving you good news but I am sure from your description this is what has happened.


Sorry to give you bad news---see for yourself if you cover each lens one at a time--if you do this and the marks are gone you know exactly what has happened.

IF YOU HAVE ANY QUESTIONS OR NEED MORE INFORMATION--let me know here--I am here to help but cannot always give good news.

The picture is off color and i dont know what is wrong with pic....please help me. thanks


if the convergence or color alignment is off, then you need new convergence chips, this would require a repairman, if the whole picture is dull then you need a lens cleaning or if it has alot of hours of use, the tubes may be weak, usually when the tubes are weak, the picture might blink on and off every second.

Rear projection tv picture quality loss


most of these sets have 3 lens for the three picture tubes inside and also a mirror---if it has never had the lens cleaned they could be dusty and this will diminish the brightness and clarity of your picture---if real dirty the picture will look washed out------most of these sets you can remove the back cover(unplug set first) and gain access to the lens ; clean them with a lens cloth or a paper towel with glass cleaner.

Screen Distorded


You're either missing a piece of the screen or something's installed wrong. The order should be 1: front protective screen 2: the lenticular, and 3: fresnel lens.

All is supposed to be assembled with double sided tape, one being a special ultra-thin clear tape. DO NOT USE GLUE

Good luck, Mark

I have a old 61 inch tv the lens are out. Are these lens still available numbers on them are 646376-1 delta 24 passed 08121490 by U S Precision Lens inc Cinn. Oh.


The lens isnt the problem the tubes(CRTs) are what go bad. Whats your model number I may be able to help you out. The other site I work at has a huge inventory of used picture tubes that are all in good working order. Finding new tubes for anything older than 97 models is almost impossible. But post your model number and I should be able to help you out.

Can I clean projection tubes myself?


First unplug set and remove back cover then you should see the three picture tubes . Using a soft cloth spray windex on the cloth then clean your lens and use the dry side to wipe away . Do not press hard as the lens are plastic . If you cannot see the tubes thru the back side you must enter thru the front . Would need to know make and model # of your set located on the if you need more assistance . If you are a smoker this could very well improve your picture . Good luck
