Question about Mitsubishi VS-45607 45" Rear Projection Television

1 Answer

Projection TV mirror

I know a bunch about electronics but not much about optics. I recently acquired a 45" rear projection crt tv with convergence problems. After digging around in it i nodiced that the mirror was cracked and the lenses were dusty. First, how much would it effect the picture to have a crack across the mirror, I know it would hurt the picture but I'm not sure how much. Then, is the mirror anything special or could I just go to a local glass shop and have them cut me a new one? Lastly, is there any special cleaners that I should use to clean the lenses or is there any cleaners that I should stay away from? Thanks in advance.

    Thanks! I'm glad I'm going to wait until I get a new mirror saturday before I rip into the electronics. I might eventually change out the chips....but if it isn't broke, don't fix it. Thanks alot

    When moving furniture around the mirror in my tv broke during a fall. We plugged in the tv to find the power and bulbs are still in tact but there is no picture because of the broken mirror. Is this a special mirror that needs to be obtained by the manufactuer or can I simply get a mirror cut to size from a local glass company. Please advise.

Good Day, Hazardsneon;
A cracked mirror will have GREAT influence on the quality of your picture and will look like the TV is experiencing a convergence problem. Good Luck, big IRISH.

Good morning, I am in the moving business and have a customer that wants me to move their large TV Mitsubishi medallion tv. She thinks is comes apart in two peices for easy moving and I need instructions...


If the model is a WS-65809 that sey doesnt come apart. Actually very few rear projection TVs can be seperated Some RCA TVs can be disassembled to several pieces. Also I would let customer know that because a CRT TV has three CRTs that are aligned to each other , Moving the TV will cause the convergence to be adjusted. Based on model it can be just pressing the auto convergence option with the remote, But older rear projection TVs (2003 and older) have been known to blow ICs after a move when trying to reset the convergence. The ICs weaken over age and they can blow anytime the convergence adjustment feature is used, so its always a good thing to let someone know that even if very careful when being moved there set may develop convergence issues after a move because its a 3 CRT rear projection TV

Hitachi ultravision 50ux26b. Two problems. 1. In the top left corner it looks like a dogear with the picture behind it faded and the edges looking blue.This started shortly after a couple of moves...


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

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. In some cases the TV will also not show any video. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....


  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) 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.

Picture is blurry


Check all of your video connections and make sure everything is connected properly. Make sure your video sources i.e. cable box, etc. are configured to the proper output resolution. Since your T.V. is a rear projection CRT, I would recommend you do a convergence calibration. This is usually the problem with those kinds of televisions when the picture gets blurry- especially if it has recently been moved. The convergence procedure re-aligns the electron guns inside the T.V. Consult your manual or download one if you are unsure how to perform the convergence calibration.

46PP9302/17f convergence problem maybe....


You need the STK392-120 convergence amps replaced along with possibly a couple of 6.8 ohm resistors.As a technician this job can range anywhere between $185.00-$250.00.If you can solder the dificulty level will require some electronics experience.Good luck!!
