Sony KV2680R Console TV with bad color

I have a Sony KV2680R Console TV with bad color. It is all washed out in purple. The remote is also shot. I was wondering if it is possible to get a new TV replaced into the cabinet or if it is better to take it in for repair.

make sure no magnets, (speakers) are close to tv.
Magnets attract the color. TV's used to have to be manually
"deguassed"(demagnetized) Look for magnets placed close to TV. Speakers have magnets in them. It might save you a repair bill.

The tv shutting off can be explained by some kind of protection circuitry turning the set off.. This can be due to a variety of reasons most common reason being overheating.

SOURCE: bad color scheme - cannot adjust enough

If you haven't already done so, it may be that all you need to do is adjust the convergence after moving the set. You should find convergence and its adjustments in the setup menu

This kind of problem occurs if tv screen got hit by some thing that damage internally and its irreparable, second possible cause is magnetic field nearby screen, please check any speaker or some thing that has magnet inside around tv, remove it from tv to fix purple hue at top of screen.
Unplug tv from AC wall socket for 20-25 minutes, replug back in and turn it On, this will demagnetize screen to cure the problem.

Intermitant color bursts of red, green, purple


for the color problem,most likely you do have problem with loose contact of components from C-board ( small board connected at the back of CRT "picture tube" which drives every color and size of the screen)if you have knowledge with soldering electronic component parts, resolder this board and also check main board for possible loose contact.

Check any magnatic device near TV which causes purple color on screen. That device can be Speaker, Electronic toy, Watch like that carring piece of magnet inside. Remove that device and turn OFF your TV for half a hour, then power again. Hope the color will be fine n normal on entire screen.

Triple picture and purple bubble on big screen

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.

2c07611.pngSolution #1

You need to replace the convergence chips and convergence resistors. Check the site 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.

2c07611.pngSolution #2

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