The Toshiba 55H70 is a standard rear projection set. It does not have a "lamp", it has 3 picture tubes. When the colors suddenly do not line up on the screen, it means that one of your convergence output IC's has burned out and needs to be replaced. This is very common on those sets. If your set is using the STK392-110 IC's, it is probably a good idea to go ahead and replace both IC's with the newer upgraded STK392-150 IC's. The IC's should be replaced and the convergence circuits realigned by a qualified tech familiar with Toshiba projection sets.

We have a panosonic projection hdtv and the msg on our tv said replace lamp and reset the lamp hour meter well we did that and now its kinda blurry/double vision i called the manufacture and said ill need...

In your tv the image is generated this way: the bulb makes the light; that light is reflected by a panel with a lot of tiny mirrors which generates a black/white image; that image goes thru a set of colored disks on a wheel that rotates which gives the image color; that image goes thru a set of lenses (called the image engine) and it's projected on the screen.
No convergence here - you see the fuzzy image because either the color wheel isn't aligned properly or (more likely) the lenses in the image engine are deformed.
The second one can't be fixed and replacing the lenses will cost more than the tv is worth. You might be able to realign the wheel, but this must be done by someone with a lot of experience and it will be costly.

The picture is showing a double image and is distored.

The problem you are refering to is more than likely a convergence problem. The convergence circuit in your tv is controlled by an IC (integrated circuit) stk392-110 and it makes the 3 colors (red, blue, green) line up/converge together to create a clear picture. You'll know when this part needs to be replaced because the picture you see is 3d looking and possibly bowed on the top or bottom or on the sides in any or all 3 colors.

JVC AV-56WP74 Colors quit working or went out of balance.

Guns or CRT are probably ok. Your TV needs a convergence IC STK392-120 replacement. Lamp are used on LCD and DLP rear projection TV's. Color wheel are for DLP's. :)

My picture won't show after replacing the lamp

Actually that humming sound was not the lamp, the humming sounds come from color wheels when they're going out, and since the color wheel is part of the light engine system and it's not working, that's why you don't have an image, you'll probably ask your self why, since it's not the lamp.. the thing is that the light engine system is componed by lamp, ballast, color wheel and dmd board, so when one of these doesn't work, there will be no image reflected, because they work together

Samsung HCN4727W Rear Projection TV, green screen, audio works

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...

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

You can see some more examples and find a fix using this link on Fixya http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

Double Image Red and Green

Here are some of the most common symptoms and example photos of a convergence problem

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.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

Solution

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.
