We have the Mitz HD 1080 and the picture has a concave curve throwing off the colors and images. May be temporarily corrected by turning the tv on and off but only works a few times.

    This Mitz HD 1080 is the WT 46809 model and has three lens on the back of the tv. I see other postings where the people say that the tv bows in the middle and appears to have a 3d look to it.

    I don't see the box you describe. Any other suggestions?

Hi,

Since by switching it of/on the issue gets resolved , Not sure whether the issue is serious. But for your future requirements please do the following:

Resolder the Thermal Deguassing Cube. It is usually Black, about 3/4 inch cube and will be located close to the deguassing coil plug coming from around the Picture Tube .

Also make sure there is not anything with a magnet around or on top of it

Thank You

Projection sets have two very common problems.

The first common problem is convergence


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,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

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

*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

Mitsubishi 1080 hd series 65" Curved picture


The problem is the convergence circuit.
Mitsubishi used two different types of convergence IC's in this series. The first is a pair of STK-392-570, the second is a single STK393-110. The only way to fix the problem is to replace the appropriate IC'S. In some cases the problem may appear to be intermitent or loose solder connections. Save yourself the anguish and replace the IC'S.
Getting the PowerSupply/ Convergence board
out to do this is tricky and I recommend a professional to do it. Hidden screws on the front of the heat-sink make it difficult to take out and you can break the board easily trying to force it.

We are getting ghost images and the color is not correct


I have red concave lines going across the screen, plus wording appears double like a ghosting effect, this is ongoing from the time the tv is turned on until it is turned off. This started 3 days ago. Is it time for a new tv, its 9 or 10 yrs old now.

Concaved distorted picture in 1080 Mitsubishi 65" TV.


This is a convergence rpoblem that is either bad connections on the pins of the convergence ICs or defective ICs. If you can solder and are comfortable working inside TVs where there are potentially dangerous high voltages, let me know and I'll provide additional details and instructions for fixing this yourself.

PICTURE


By the picture that you have supplied with the question you have a rear projection tv. The problem you are describing sounds like you have had the convergence module in your tv fail. Depending on the age and make of the tv, the repair costs ( if out of warranty ) can be prohibitive. The convergence module on rear projection tv's not only is in charge of bringing the 3 different color images together into a watchable picture but also handles the east west correction ( concave / convex aspect to the picture or lack there of ).
