Color problem with Toshiba

My picture on my Toshiba rear projection tv is off. The images project a blue outline. I aligned the screen but on the alignment line in the right the blue one is bowed and wont align. Is this a bulb problem or has my tv seen its last days.

Sounds like a problem with convergence, poss just requires new STK 392-110 ICs , may need a couple of resistors that go due to faulty ICs

I have a toshiba tp50h50 rear projection tv and their is a blue shadow behind the words and makes the words a little blurry

Sounds like you need to do a color convergence. If you still have the owner's manual, it will give great detail on how to do this. The convergence menu is accessed from the video menu on the tv.
The tv has three color picture tubes, red, blue and green. The convergence alignment adjust each tube so that color from each tube overlaps each over to create a white image on the screen. Most tv's only allow you to adjust the blue and red colors.
Convergence should be performed each time the tv is moved and at least once annually.

I believe the blue lamp in my 57H81 is going bad.

You need to replace convergence out chips in your Toshiba 57H81 tv by qualified tech because 3-D look picture in rear projection tv shows some thing wrong with convergence output chips.
Your tv model number shows it is rear projection tv that use 3 tubes to make color picture on front screen where as dlp tv use one lamp as back light source to present picture at front screen that is generated in light engine.

Wavy picture with blue and purple color.

Projection TV sets have two very common problems listed below.

Problem #1) 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

How do I know I need a new projection lamp? My tv

This set does not have a lamp. It has 3 crt tubes that converge to create a color picture. The convergance is off a little causeing this affect. Go into the menu and look for convergence or magic focus. You can download the owners manual from Toshiba website to do this. You will need the remote that came with the set.

If the convergence on one or more color does not align using the convergence setup procedure, that means that one or more convergence ICs must be replaced, that is the reason why you get bad picture.

That means that the convergence ICs are bad and must be replaced, the job is about $200/$300.

Red outlines in the picture

somewhere in the tv menu there is a place to make video adjustments. one should be for aligning the color guns. one is for red and the other two are green and blue. it will give you a cross in the center of the screen. it should also give you prompts to adjust the lines for centering and to save changes. this happens eventually on all rear projection tv sets.

The words on the screen is doubled or trippled.

Go to the picture control menu and turn the color to minumum so that you are watching a black & white picture. Do this to determine if the color offset affects the overall screen or just the lower corner. If the center is off, go to the convergence adjustment menu and align the red and blue onto the green as described in the owners manual. Some models also allow you to align the outer edges as well. If the bottom is still bad you may have a problem in the convergence circuit. If the outlines are not seriously bowed or distorted a minor convergence toutchup by a qualified technician should correct the problem, otherwise parts are involved and the repair is considered major.
