Question about Sony KP-51HW40 51" Rear Projection Television

1 Answer

My JVC model number AV-56WP30 has a flashing convergence screen

My TV is flashing the convergence screen, but I can still hear the audio of the TV program. There is no response when I use the remote control try and set the TV automatically to adjust the convergence. If I unplug the top end of the convergence board that is standing vertical inside the set's main electronic board, the picture moves from a flashing convergence screen to a regular tv picture, but all of the colors are completely out of adjustment and the picture is warped. Can someone help me?

Thank you,

Mark

    Thanks for your advice! It scares me a bit, since you said that you had never seen my type of symtom before. It sounds like it could be something more serious.



    Thanks again.

Your TV most likely has a Convergence Chip Failure but I have not seen that symptom before.

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.

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.

Convergence is off on jvc av-56wp30


You will need to install a convergence repair kit which contains two Convergence ICs STK392-110 and then the associated resistors as usually a JVC will Need at least 1 or 2 of the resistors when the ICs fail. You can get the kit for your model at the following link which has the IC and all the resistors plus step by step detailed instructions on how to do the repair. This kit fits your model JVC

AV-56WP30 not allowing me to access convergence menu


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

No you cannot! There is a switch on the convergence pnl for complete convergence. You can make things 10 times worse if you don't know what your doing.
