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.

color going - 3dc9420.jpg

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.

lololol HD to standard video - standard video back to HD is going to cause some issues. Go straight HD to HD with a hdmi to dvi instead. Even if your tv cant do HD theres a loss of information and signal for every adapter you put in and the length of the cord.

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.

Screen keeps losing colour and ends up with a blue tint


On this model there tend to be two problems. One is that the power supply capacitors fail early and often. While this typically caused no power or slow power-on, it can cause other issues as well.

Loss of color typically means the 'Main Scaler board', which is the main board where all the inputs are attached, is having an issue.

There are some problems reported with a faulty crystal on the board causing loss of color, although most techs would just swap the board as these TVs are meant to be serviced at the board level, not the component level.

I assume that this loss of color happens on any input source, including when using the internal setup menu of the TV? This would help to confirm that the loss of color is not related to a faulty input signal caused by a bad cable.

DVD player only plays in black and white on Soniq 42'' Plasma TV. (Have tried 3 different players all have the same problem)


The color loss is most likely due to a NTSC/PAL compatibility issue. If you bought the players overseas in a PAL region (http://upload.wikimedia.org/wikipedia/commons/0/0d/PAL-NTSC-SECAM.svg) and the TV is NTSC or vice-versa, there will be a color loss. Thiss because the different regions have different formats and when you go from one to the other, the color does no transfer over. You can buy a PAL to NTSC or NTSC to PAL converter to fix this issue.

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.

RCA F31317 lost blue in picture.


this symptom is characterised by the loss of one or two primary colours. this symptom can be classified into three cases: 1) loss of red colour, 2) loss of colour blue,3) loss of green color. this symptom may be caused by a trouble in the colour demodulator, in the color amplifier or in the colour subtraction amplifier circuit. in your case loss of blue colour. this is a very complicated problem that you need some special test equipment like oscilloscope and color pattern generator in order to trace the signal. tune the receiver to a color broadcast station(a colour bar generator can be used to transmit a colour signal to the set). check the Z-axis demodulator, z-axis amplifier and the B-Y output circuit for the chroma signal. observe the signal process with an oscilloscope. if the color signal is not present use a VOM to locate the defective component in any of the above circuits. check the transistors and the resistors in the collector circuit. good luck!
