Double vision on tv with purple and green colors


Hello,

This television set, as well as most rear-projections, is prone to convergence driver problems. There are two large chips (STK392-110's) in the TV that need to be replaced, as well as some resistors that are likely damaged as well. Any competent TV repair shops should be able to repair this TV for 200-300 dollars. It is important to note that if the back of the TV is taken off without the proper prep., the Digital input (DVI) will be disabled permanently.

Hope this helps you...

Line at top of screen


There are problems in the vertical blanking or scanning circuits. This is not something you can fix yourself at home. It involves troubleshooting the deflection amplifiers and scan generator areas to locate the defective components.

You will have to give the set out for service. I would suggest to get an estimate before proceeding. This type of repair can be costly for the labor to find the fault. If it is only generic type parts involved, the parts themselves will not be too expensive.

Curved red lies at top/bottom with some double vision in lines


This is from another fixya article but its relevant to your problem.

Your TV most likely has one or more 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 aroundimages.

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.

My toshiba tn61x81 projection tv


have you tried the convergence option in the menu? i believe it is under "picture". this allows for nine different sections of the screen to be adjusted when projection images get out of whack.

BLUE DOUBLE VISION


It sounds like you may have a loose solder connection either in the convergence circuit or the pincushion correction circuit. If you can't visually locate it, you may need a service manual and test equipment to track it down. I doubt that changing parts will be the cure if it is an intermittent problem.
