maybe the lamp has died. If it has we could assist as we are a international lamp distributor. www.iceav.co.nz [email protected] Kevin Andreassend +64-9-4142348

Thats a common symptom for your model. The green CRT has shorted or the Green CRT drive board is defective.

The Convergence circuit sounds like it has failed. Have you tried the auto focus button. if nothing happens, it is the Convergence circuit.
Hope this helps,

Adjust RED screen drive down, or disconnect,unplug CRT board from red tube turn set back on if it plays without shuting off RED tube is shorted or video IC on CRT board is bad.

apply fresh solder from CRT board. chek transistor red color amplifier. KR, KG, KB. check voltage DC.

I followed GuestUser/ Slinteriors advice and I fixed it. Open the front of the TV and there are 6 little nobs in the front. The botton 3 are what you need to adjust. from left to right the color controls are BLUE, RED GREEN. For the blue lines, slightly (I really mean very slightly) turn the botton left nob clockwise (right).

If you know how to adjust G2 (screen) volt adjustment then increase a little bit screen volts of red and green lamp.

Its convergence problem.
Let me know do you want to fix it by yourself?

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.

Solution #1

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 around images.

Picture of a set that needs the fluid changed.

Solution #2


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.

The problem is not a cable one, but a TV function. Pull out your user manual for your TV. My dad just had this happen, and he has a Sony WEGA TV. The auto sap is an AUTO Secondary Audio Program, you need to find the menu to back out of it.

Good luck.

when TV goes to power off (standby) does it standby light blinks?
Please count light blinks and let me know.
Is it Sony KP-65WV500 model?

Hi, sorry. but this is not something you can do, after replacing tube there is a large alignment procedure that must be done as well.
total time for a seasoned tech is 4-5 hours if everything goes well, my advice is to call every shop around you for the best deal, hope this helps, video-tek

not if it keeps repeating the same cycle over and over..it cost 300 once and if you have it fixed again thats another 300 and if it happens again so on and so on....

you need a new power supply board

you need a new video board

i have one that might fit

OK, I'm the guy that was having the same problem, but had a blue tint to the screen. I also had blue lines running across the screen, and when I followed the steps below that were posted by another user not only did the lines disappear, but the blue haze vanished as well. My tv looks like it's new again, so you may want to try this:

I have fixed this several times on my KP 65WV700

As Slinteriors posted if it is a thin curved line you need to adjust the screen control, it's sorta like a brightness for each color, and if one color is too high it will produce a thin curved line.

The best way I have found to get to the controls is by removing the lower grey speaker cover front the front of the TV. There are 6 screws if i remember, 3 on each side. Then it snaps off, seems like its going to break but you have to pop it off pretty good.

Once its loose you have to remove a cardboard like cover plate in the center that will give you access to the small controller board.

Now be very careful while experimenting on which knob controls which colors. Turn them very slow, if you turn to fast you will cause your TV to shut down. If this happens, turn the adjustment back to original spot and turn TV back on and take it slow.

Adjust the correct color until the line just goes away. Its easiest to do this with a black screen.
