Re: Convergence problems on AV-48WP30

Excellent diagnosis by Carlos. IC804 controls red convergence. But in time IC805 will also fail as well. Replace them both with STK392-110. Also, check for cold solder joints in the vicinity of these ICs. If you want a schematic for this unit e-mail me.

  I didnt think so many people had the same problem with same TV...kinda scary.Well add me to the list ...can I get a copy of the diagram please so I can give it a shot, thanks.

      Hi Eric, would you be able to send me the instructions/part #s, etc. for this fix as well? I am not only having convergence problems, but a little bit of the picture on the top left is black and a little blurry. Also, part of the picture on the bottom right drops off. Thanks in advance for your help.

  Hi, I am having convergence problems to I see goosts in three colors, and at the center of the scren it seems all is ok, but at the top of the screen, a green arch is present, and at the bottom a red arch is present if you can send me the diagram and the most information you can I will thank you.

  Hi Eric
  
  My AV-48WP30 has the same problem with the convergence. Can you send me the instructions? Do you still use the STK392-150?
  Thank you

      Hey, I'm having the same problem on the left side. I am going to fix it myself. Do you have schematics? Or any tips. Thanks Matt

  Please send me a schematic on how to replace the IC convergence circuit 392-110. Thanks

  Hi, I have an issue with my JVC AV-48WP30.
  The screen has large red streaks from the left.
  Also the red color convergence is way off.
  If this is the same issue you had stated you had a repair
  for, could you please email me this schematic.
  
  One more thing if there is a way to write a small walkthrough
  on this fix I would be very greatfull.
  
  Any help would be great. Thanks!
  
  Tony

      Eric, It looks like this convergence issue is a pandemic. I know you are probably sick of sending the instructions to replace the IC's by now, but I would appreciate if you would send them to me. I have the AV56-WP74 and I am having the same issue. Thanks, Larry

  Hi,
  I cannot line up the Green convergence X's in the 1 2 and 9 postion, In fact the top left screen is twisted. Any clues would be greatly appreciated. Thankyou
