It is the fault to its video output card. This card can be located at the back of the picture tube, directly plugged on on to it. Check it for any loose solder terminals. Re-solder all the suspected solder terminals by applying a little more solder. This must solve the problem. The fault is called on color predominant screen.

SOURCE: Red,Blue,Green Image

YOu have convergence issues. Ok first question. IN your setup menu do you have the convergence option/ if you DO not then it can be a specail fusable link. fl231 if you do. next question do the picture bow in at the middle. if you do then it possibly a convergence power supply issue. next if you go into setup convergence does the crosshairs adjust up or down left to right on both blue and red. I if so then theres is a chance that it can be a convergence adjusment or a amplifer problem AS always THIS SET CAN GENERATE LEATHAL 380 VOLTS EVEN WITH SET UPLUGED SO BE CAREFULL.

SOURCE: HAVE 3 PICTURES,1 IN BLUE, 1 IN GREEN, 1 IN RED.

Your TV most likely has one of two possible problems.

Problem #1: Convergence Chip Failure ( common problem )

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.

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 note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

SOURCE: Our Mitsubishi WD 52525 goes to blue screen and shuts off.

It sounds like you TV is overheating and the video is suffering and the lamp is overheating as well. Also, if your TV is over 2-3 years old, the mirrors (behind and below the big front screen) desperately need to be cleaned. Clean all filters and fans as well. (Look on side and behind the unit). Is the TV in a "hot" environment and/or dirty environment? DLP TV's are NOT sealed units. They need to be cleaned every few years to work well to have a good, clear, bright picture.

Can i fix my tv screen is red


Toshiba 36A10 36" TV is the model you have indicated---

If the screen is all red and or too bright (no green or blue can be seen) the problem is in one of two places: Either a shorted picture tube or the board that plugs onto the end of the tube.

That board sends red,green, and blue video and information to the picture tube via 3 pins on the tube (the K or cathode for each).

The set will have either 3 IC's on that board or 3 transistors, or a single larger IC for this.

to troubleshoot this:

I would locate the Red Cathode and unsolder that pin at the socket on that board--takes red out---if you have green and blue picture then---it is either the IC/transistor that feeds that on the board or the tube itself.

If it has 3 chips (usually will each have a metal plate attached for cooling) you can either remove and replace the red one OR what I do is swap it with the green or blue chip---if suddenly you now have a blue or green only screen you know that part is bad--simple as that.

If for any reason the picture tube turns out to be bad--you are finished and so is the set= way too expensive to replace it.

Let me know if you have questions or need advice.

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!

The color on the screen is green when I watch movies. How do I fix this problem?


Good day sir, your inquiry about the green lcd screen can be caused by several things. 1. The monitor/tv produces 3 colors, red green and blue, the tv mixes these three colors to produce the picture. a loss of red and blue produces this green screen. so check the cable, specially the red and blue jack of the component inputs, and the red and blue cable. 2. there may be loose contact on the signal cable. try using the video input instead of the component input. 3. the dvd player may have the problem, check the player component out jack. a loose jack port can cause these problem. hope this may help. thanks

Green Screen instead of Blue


Check the picture settings on the tv, if that is not the problem, then check all of your connections (RGB cables+RW Audio) that is HD component, if you have both HDMI and HD component then try one of them, or it may be a switch in the back of the DVD player or TV

Toshiba 32AF41 Power up Problem and Green Screen


My first inclination would be to check the picture tube, especially if the set is over 7 years old. If it is not that, then anything from bad solder connections to capacitors or a defective IC could be the cause. If it's over 10 years old, replace it. No use flogging a dead horse.
