Annoying diagnol lines in background

Greetings Experts, Just this past weekend I had my STK chips (blue and red convergence) replaced. The color is fine but now the picture quality has degraded. There are these faint diagnol lines that start from the upper left hand corner and continue down to the lower right hand corner. The repairman who installed my chips didn't seem to know what he was doing when it came to adjusting the blue convergence... it took him an hour and a half to get the blue convergence right (and he pulled a manual after the 1st hour of trying). He told me the lines were b/c of the cable sigle, but my DVD's have the same poor quality so it can't be the cable signal. The set is only 4 y.o. and it p.o.'s me that I just spent $500 on convergence problems and now I have crappy picture quality. What do you pros opine on my situation? I ordered the manual b/c I am frustrated. Any advice would be very much appreciated.. thanks fellas. Gus

    Thanks Techman, but I live in NYC and everything is ###@## and "you don't get kissed". But how about giving some USEFUL info. I didn't post for people to say how much I got screwed... I just want an honest answer to my problem unlike the company who repaired my TV this past weekend. USEFUL comments are welcome.

    Didn't mean to make it sound personal techman. Of all the repair shops I called this one was the cheapest, believe it or not. Some didn't even want to give estimates over the phone-- I suppose that's their way of shafting you even more. At any rate, thanks.

    They are faint, not really white, and it sort of makes the picture quality "fuzzy" like. The thing is they are not visible when I first turn the tv on. Then after a few minutes the lines become visible.

    If by the RGB screen you mean a screen that looks like a grid, yes the tech messed around with it and had no idea of what he was doing, or so it seemed. In addition to the line problem, part of the bottom part of the picture is cut off, e.g. during football games I can only see half of the score ticker at the bottom of the screen.

    I appreciate your advice. Also, I am not a tech, so if it's not much trouble, could you "dummy it down" for me... Thanks again.

    Thanks Techman. The same service man is coming this Friday. I'll suggest to him your advice. Hopefully he won't feel that his manhood is offended and follow it. In the event that he doesn't want to heed it, what should I look for? Thanks again for your advice, and I'll keep you posted on developments. Peace.

Hi, I get black lines when I use 480p with my cable box. When I use 1080i, i get no black lines. can this be your problem? When I use a dvd, I dont get any lines at 480p. Did you try to to correct convergence yourself? Through user settings and service menu? Gus, Where did you get service manual from for tv?

Sorry to tell you gus, if you paid 500 bucks for convergence IC's you got #### and didnt get kissed. A repair like this should not go much over 250 to 300 bucks.

    well excuse me! Are they faint white lines? Because if they are, the RGB screens are most likly too high.

    Ok No problem as I didnt know you were a fellow NY er. I used to live in Kew Gardens queens. Had a shop in New Hyde Park. If I were you I would call the tech back and tell him the vertical size is misadjusted and the RGB screens are slightly to high as thats what it would look like if these things were not adjusted right. Its not a good Idea for a untrained person in the field of electronics to be messing around in this High Voltage circuir. So tell them the three screen control are too high and the vertical height is not ajusted properly. If they do not wanrt to come back out, report them to the consumer affairs, as they are much worse on shops then they used to be. and if this shop is unlicesnced then its a good thing you would be doing.

I have sony tv kp-65wv600. It has problems. color and video is blurry, double vision, letters are curved


You have a convergence failure.

Convergence IC failure is very common. The solution is to replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu. It is about a $300 repair at a tv service center. You will need the service manual if you decide to do this yourself.

Try This:
When you notice the symptons Use this simple test to verify.
Go to the users menu on the tv.
Look for the converge option probably under setup or video setting. Converge is short for convergence to align the red and blue colors to the green color.

If you cannot move the red either horizontal or vertical, then the STK chip has failed for red section.
If you cannot move the blue either horizontal or vertical, then the STK chip has failed for the blue section.

If you can move both in each direction then the problem is something else.


Note if one STK chip fails, you replace both regardless

At times the screen becomes double


When you say "double" do you mean you see the colors somewhat seperated or see maybe blue or red outlines around objects? Does the screen distort?

If so then:
Your Convergence ICs are likely failing or it is a bad solder joint related to that area. It is very common on rear projections. The solution is to replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu. It is about a $300 repair at a tv service center. You will need the service manual if you decide to do this yourself.

Getting "red" double image


Your TV most likely has a 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.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.

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.

0667c5f.pngSOLUTION

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.
