Tv shuts off quickly ( 1-2 seconds)

2blink-then 4 blink---------vertical circuit problem

This is a general answer based on error code--problem in vertical circuit then the first thing is to look for ANY signs of Glycol having leaked from one of the picture tubes onto that area of the board.

If you do not know how or what to look for let me know and I will explain.

Vertical circuit deflects picture from middle to top and middle to bottom of screen; if set detects that it shuts set off instantly to prevent a instant BURN MARK from happening on all three tubes this set uses--prevent permanent damage to the screens of the tubes.

Picture arches down at the top and arhes up at the bottom

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 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 that includes replacement coolant, photos. instructions, etc.

Vs 6041 - no picture day 2 days after installing direct tv

Is it only the input that has the direct tv connected to it that has no picture, or do you have no picture at all on any inputs? If you are able to watch a dvd on say AV1 or input 1 but have no picture on the other input that has the direct tv box connected to it I would call direct tv and have them look at your box. If you have no picture at all then it is your tv. and it being 10 years old it is almost a natural failure a strange occurrence that being it happen right after you got satellite.

Blue wide streaks in my 42" Sony TV model KDFE42A10.

I have the same TV and the same problem and it's also just over 2 years old (bought it June 2006) when the problem started. Every day, I saw the blue streak cover more of the tv, now 6 months later, it has all turned to green and the entire tv has a green tint. It looks like I am watching tv in murky green water.
I am lucky that I purchased the additional warranty on the tv and finally got around to calling them. I hate to tell you this, but they told me that the optical light has gone up and they are replacing the tv.

Sony KP-57WV600 rear projection

sounds like bad CRT, some of these sonys have had defective CRT issues, usually all will come and go sooner or later (all 3 bad), you can pull the speaker grill off(either 2 1/4" screws on bottom or 6 1/4" on back sides) and pull off the Crt box cover (2'X3' piece) and lightly tap the CRT's with tv on, if they flare or get colored streaks in pix they are bad, CALL SONY 800 # and complain, also could adjust G2 (Screen control for color) for short patch. Will need new crts.
