I'm having issues with color? Every blue is now green. Can't adjust the tint. Any fixes?


You didn't say what the model number of the TV was, so I'll guess it has tubes for each color Red, Blue and Green. The blue tube is probably weak. If you really want to spend the money on replacing the tubes (costly) you may be able to buy a similar sized flat screen TV for less than the cost of the repairs.

After turning the tv on the colors are reddish and slow to conform to the normal color tones. i have a 36" toshiba flat screen tv


My first concern would be that, the picture tube is going bad. The problem you describe, tell me one of the color guns is shorting. In this case I would think the green gun is shorting. There are three color guns in the neck of the picture tube. They are red, green, and blue. Most of the time the green will short as it is powered heavily in most TVs. The next thing to check, is the small board connected to the picture tube. Look for any and all bad grounds on this CRT board. This is another big problem in all Tube type TVs. On this small board there will be three color output transistors, and resistors. These will many times run very hot and will create bad grounds over time. Check and resolder as necessary. If the CRT board does not fix your problem, replace the TV. Picture tubes are very expensive and will not be feasible for replacement. Search for a new TV. Thanks for asking and show all hands of support!

Image is green color............what is wrong with the tv?


It means that the blue and/or red picture tube (bulb) is not working properly. It could be the tube(s) or the circuits that drive the tube. My money is on the circuits.

Tv comes on for 10 seconds then fades to a green tint then turns completely green for a few seconds than turns off


Hi,
Symptom shows tv got problem with green picture tube that need to be replaced.
Rear projection tv has 3 picture tubes, red-green-blue to make color picture.
Since its an old model so spare parts would hardly be available and local tv repair shop will help you to arrange required part, if they can.
Thanks.

53 inch projection tv...seems like the color red and color blue have shifted giving me a picture with red and blue shadows


For CRT projection TV's, this indicates that the Green picture tube is burned (warn out). The less green that strikes the screen, the more redish the image will look. You will need to find an old school TV repair shop that knows how to replace picture tubes.
In the case of a DLP style TV, the color wheel needs replacing.

My Sony KP-46WT500 screen shows the tv image in blue only for a few seconds, then it goes completely blank (as if it were off). Do I need to replace the bulbs?


It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.

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.

Check settings first to make sure no one changed anything out of the ordinary. Are the shadows that of a color or darkened shadow? It could be out of convergence, which can be corrected in the menu - or it could be low quality video cables to. Also, if there is no green, does a white color show up when you're in a menu mode (Red+Blue+Green = White Image)? If so, then the green picture tube is working and it's just a color adjustment, otherwise you may have to invest in a new green picture tube.
