Picture seems sunk in and the color distorted with doubleing effe


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. 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 projeciton 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 photos of convergence problems.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

RCA TV lost Color


It sounds like your grandson found the "monochrome" setting in the menu on your remote. It may be in the "picture settings", "set-up" or "advanced" setting.

Green & red tint


Most likely nothing you can do to fix this. CRT TVs use 3 colors to make an image on the screen (Red, Green, and Blue). If you're only seeing red and green then chances are the blue has stopped working. You can replace certain parts in the TV but for a 27" TV you'll probably end up paying more for the repair than a new TV.

I don't recommend taking the cover off and trying to fix TV yourself without training. CRTs have a lot of electricity stored in them (even after turned off) and you could accidentally electrocute yourself.

My tv was dropped and now the color is messed up how can i fix it


Unfortunately, this can't be fixed without replacing the picture tube. The drop caused a piece called the shadow mask inside the tube to warp or break loose. When that happens, the red, green and blue beams in the tube don't hit the right places on the screen. There isn't any way to repair this kind of damage.

If you had professional movers doing the job, their insurance should cover some or all of the cost of repairing the TV (replacing the tube, that is) or replacing the set. I wish I could give you better news.

Dominant blue


Can you post to the party who has too much green how to adjust the video adjustments? They need to know so they can see if
its just a simple adjustment.
In your case, first turn the color level clear down to where you
have a black and white picture. As in the case of too much green,
question is if the picture is black and white or if there is a color
on the screen so its blue and white? I suspect it will be which
is typical when the guns start to fail. Likely the green and red
guns are weak in output. There are screen adjustments in the set that a tech can set up that may help some, but the only real fix is to replace the guns which is expensive and requires a complete allignment. All 3 guns need changing to get it back to spec and it is a good idea to replace the flyback for reliability. Get an estimate and likely you can replace the set for the same money.
