Convergence problem The convergence looks aligned in the center and is out of alignment as it get to the edge of the screen. The auto convergence has no affect. Ted

    picture was blurry at right and left edges and out of convergence. the center portion of the screen was perfect. This started on the edges and over a 1 week period worked its way toward the center until finally the screen shrunk and started vibrating dramatically as it shrunk down to the bottom of the screen and than all was black. No sound or picture! Any ideas out there? Does it have a cost effective fix ($500) or less? Thanks!

One or both of the convergence IC's are bad and has blown one or both of the fuses. Pull off the front speaker grill and remove the cover, loosen 2 brass scews holding the aluminum frame work, lift it up and out. Inspect The convergence IC's and the soldered connections to the board, check the fuses on the board. Replace both IC's and the fuses.

Tv out of foucs


These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

The color is way off on the tv. It also looks curved, like if there are words on the tv they go up at an angle toward the edges of the tv. When you try to align the color on the tv you can get the center...


This is a common problem. Its called a convergence failure.

Problem #1) Convergence

Symptoms:

  • Screen Looks 3D
  • Colors wont align
  • Video may look distorted
Problem #2 CRT Fluid has clouded over. Symtoms
  • Dull looking video
  • White looking video
  • Halos around objects
  • Red/Orange looking video

Pushed the auto convergence auto set by mistake


This is a problem with the convergence circuit and was not likely caused directly by you. The burning smell was a resistor smoking. You now have a defective convergence IC as well as a few open reisitors that will need to be replaced. If you can update this with the model number, I will list the parts you require and the costs. Expect the parts to cost in the $25-$35 range.

JVC AV56-WP74 Convergence problem


Hello saduchan,

I think that your ICs are ok, What you need to perform is what is called dynamic convergence, This involves using the internal convergence controls to align the outer edges of the screen. I am assuming that the center of the screen is ok? it's just the edges which are misaligned, right? Now for the bad news, this task is not easy in fact the job takes a pro about 6 to 12 hours to do it right. I think you should have a qualified TV technician attempt the static convergence setup followed by the dynamic convergence setup.

I hope this helps,

Thank you,

PT-61G63 Convergance


Your convergence IC's most likely need to be changed, possibly some resistors as well.
Do you know how to solder and use a meter? If so you may be able to fix this yourself for under $100. If not you will need to repairman to repair it, this should cost around $300-$500 Let me know if you want to repair it so i can get you going.

Each color (red,green & blue) has an amplifier IC (STK-).
When there is a convergence issue,the first step is change both
IC's for reliability. Then check for open fuses devices,usually
pico fuses.Then re-check convergence alignment.......T.
