Question about HP Televison & Video

2 Answers

Sony model 51-ws510, Picture is drawn in from top to bottom in the middle of the screen (keystone) all images are on the screen but distorted. I think it might be the high voltage block assy, but before ordering it I need a pro's view on the problem. The sound is ok. Thanks, gary johnson garydj10@gmail.com

    Tbanks, the serial number is 8733955. Should I order the service manual for the set before replacing the ic's? I have looked at the boards from the back but couldn't identify the ic's visually. As I look at the set from the back I see 3 boards, the vertical one where the power comes in, and two large boards laying flat. I do appreciate the assistance. Thanks again, Gary

No this is a convergence issue. Try auto convergence if this doesnt work. Try manual convergence. If that doesnt work then its your IC chips.

    Thanks for posting picture and it really helped to understand the tv problem.
    It is failure of convergence out ICs and if you have little experience of Tv repair and solder work, you can replace these ICs.

    I think it would be nice if you get related service manual from any online part store.
    service manual would help you to find part location, board location ect.

I have problem with christie projector roadster x9


If your's is the "s" model there is no keystone adjustment provided. Otherwise the keystone adjustment is found under MENU then 1, Size and Position and under MENU 2, Image Settings. Also, refer to this excerpt from the manual:
NOTE: This function is not available in "S" models.
Adjust the keystone control if images appears non-rectangular or keystoned in shape-that is, smaller at either the top or bottom edge. The effect of keystone adjustment is similar to
physically tilting the projector forward or backward in relation to the screen, and it affects all sources.
NOTES: 1) Keystone is enabled for a source only if Size is 1000 and Size x Vertical Stretch is 1,000,000.
2) Keystone adjustment is not available in "S"
models. 3) Avoid using Keystone with Blanking.

My picture slants in towards the top from bottom


The issue has to do with something called "Keystone". This allows you to set the projector at an angle and project on an angle. When you set the projector on a flat surface, you would need to adjust the keystone to get rid of the "trapazoid" look of the image.

Text/images overlap each other in 3 colors, 3D distorted picture


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 email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.

Image Distorted


This is a classic convergence problem. Please confirm that your model is 51H84 and whether or not you intend to repair this yourself. You will need to know how to solder. If you wish to attempt the repair, confirm the model and update this and I'll provide you with details and instructions.

Sounds like some kinda convergence problem. Can you post an image please?

1 Answer

Image is totally distorted


Did you also replace the bias resistors required when you converted from STK392-110 to the higher STK392-xxx modules? If I wer you I would go back to the orginal modules only new ones. Then I would also get a schematic to test the voltage levels on the chips to make sure they are the same as on the schematic.
