Your TV most likely has one of two possible problems.

Problem #1 - Failure in the convergence circuits. ( 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 are some photos of convergence problems.

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 will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, 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. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc.

TV set after fluid change. Notice how bright the colors are now. Everthing looks crisp and sharp again.

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.

Sony Wega TV lost color now only B/W KDF-42A10 born 6/06


Sounds like it's something more than the lamp. Double check all your connections...it might be something as simple as needing a new cord (RGB, HDMI, Component Video, etc) Does the problem exist with all inputs? (For example, DVD player, cable, etc) If the problem is only from ONE input source, try replacing that cable. If it's on all input sources...might be something more internal on your TV.
Good luck

Talk to JVC as I have suggested and this is likely a known problem: loss of any color, picture upside down etc requires a upgrade to correct and I have seen about twenty sets with their name like this with this kind of problem.

The color red wont work on my tv


If Dish is providing signal via the COMPONENT input on the set look for a loose or bad red cable--hint in this case swap red cable to green or blue and if loss of color is now different--bad cable or output connection from the box.

Set (we are fond of saying this) does not know what is hooked so if one color missing and good with DVD etc it is a problem in the hookup.

I got paid triple to go to one house (nearly 80 miles each way) as set was under extended warranty for exactly this issue---red plug (component) coming out of the box was part way out.

Poor picture no color


OUCH! LARGE DARK SPOT IN CENTER IS NOT GOOD FOR PROJECTION TV. YOU BURNT THE TUBES. THE LOSS OF COLOR IS THE ROOT CAUSE SOUNDS LIKE A DEFLECTION CIRCUIT PROBLEM. THE TIMING FEEDBACK IS USED TO SYNC THE COLOR CIRCUIT. IF THE TUBES LIGHT WITHOUT DEFLECTION THEY BURN THE CENTER PHOSPHOR COATING INSIDE.

The color seems to be off. No red, and lots of purple. This is a Toshiba 57H81 wide screen big box tv. It was purchased in 2002.


Could be a bad board within the tv but it is sometimes the source input meaning it could be dvd player, cable/satellite box, etc causing the loss of color but it is unlikely. I have one of these tvs and they use red green and blue projectors to reproduce the colors so when the red projector fails then you get purple which is green and blue colors combined without the red. I have found it to be sometimes a bad connection inside the tv and I found insects such as roaches inside others. Using extreme caution when opening the rear cover of any tv due to dangerous and fatal high voltage. You might find that simply cleaning out the inside of tv and reseating all the connectors might resolve your issue otherwise you would have haul this tv to a repair shop where you pay half the price of a new flat screen lcd for just repairing this tv which will probaly have another color go out next month.

TV COLOR WENT BROWN IN COLOR


It could not be the playstation that would cause the fault. The set was probably going to fail anyways.

A brown casted picture sounds like there is a loss of the blue colour drive in the set.

Some TV sets have colour temperature adjustments in the user menu. Check to see if your TV has that option, and that the colour temperature is properly set up. You can refer to the TV's instruction booklet for details.

A loss of blue drive can be from failed components in the video path, or in the bias circuits that control the CRT's cathold current.

It is also possible that the CRT is going defective, and is losing emission from the blue colour electron-gun.

You will have to bring the set to a service center that has an experienced TV tech who can make proper diagnostics, and give you an estimate for the cost of repair.
