Problem with the Toshiba 50H13 50 in. Rear Projection Television. Green tint

The tubes have aged and the colour balance between the tubes has shifted. You will need to redo it using a black/white test image: first the black (the cutoff point), then the white (the gain) on each tube - always start with the green colour. This is done on the final video amplifier of each tube by adjusting the corresponding semiadjustable resistors.

The RCA model is a 3 CRT projection TV. Most probably you need a new RED CRT, or there is a problem with the R(ed) channel (the picture is made up of 3 component colors: Red, Green and Blue). No way of telling without testing of the projector. Sorry!

Ghost like shadows

It seems your TV Samsung HCM4215W has problem in convergence board and need to be replaced.
You can get that board from Parts Store on $76
If you have bit electronics knowledge and know how about tv repair, you can replace it by yourself or get help of local tv tech person.

Hi there.

Here goes.

What you do is first get into tube lenses and wipe them clean.
Then turn down the colour to black and white.
The simplest way to adjust the three separate colours is to get to the hv splitter box and adjust every screen pot until you get a black and white pic.
Then turn your colour back up and you should see a good result.

Samsung SRS TV

Have you attempted to go into the menu and adjusting the convergence.. Check in the menu and line up the bars. If this does not work it might need to be adjusted manually.

Thanks Steve

Bad ghosting of all colours

The most likely cause is shorted convergence chips and possibly a few pico fuses.

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,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links 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 herebb0cf99.png

Three colours don't converge

Shrink, the convergence circuit needs to be repaired, Until someone gets in there and takes a few measurements it`s hard to say what the cost will be, may just need to be re-soldered, good luck, BMW Rider
