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.

      Hi Eric; I can't believe all the problems with the AV-48WP30 convergence. Mine started last week. Could you send me the Schematic also? Thanks

      Hi Eric, You seem to be able to help with this JVC model of tv. I am having a similar problem with the green draping line from the top of the screen and a red line across the bottom. Can you please send me the info that you sent to the others in this forum. I don't have any soldering experience so could any additional steps or information on how to correct this problem would be most appreciated. Thanks in advance.

  Eric,
  
  I have the AV-48WP30 and it looks like I'm having the same convergence problem. The red is way off to the right and it will not move far enough to the left to center up. Also, the top left corner and bottom left corner look as though they are rolling down to the right (can't center). Could you please forward the manual to me as well.
  
  What is a DVM (Tool you mentioned you would need)?
  
  Thanks,
  Jeff M.
  
  
  • Re[3]: Convergence problems on AV-48WP30 Eric - 23rd Jan 2007 18:39
    Need your email address to send instructions, A DVM is a Digital Volt Meter.

  I know this was posted about a year ago so hoping you still around Eric, if so can you send me the same part of the manual. And ive never done anything like that before, so any helpful tips would be nice. This was fixed about 4 months ago at a shop in town and its starting to do the same thing, just having convergence problems im assuming? Thanks man

  I'm having problems with our JVC AV-48WP30 screen TV.
  I really need help there is green, purle and pink shadowing around the person and around everything else. I went to a convergence screen but can't figure out how to correct the problem, I can move the arrow around but when trying to get the green color or purple color to align, I can't move them.
  Could you help, I hope this is free service. If there is a charge please don't send any reply and ignore this request.
  Help...thank you.
  
  
  • Re[3]: Convergence problems on AV-48WP30 Eric - 4th Feb 2007 4:44
    Karen There is no charge for advice. But you have to post your e-mail address in order for me to send you instructions. You have a convergence problem and will have to remove the Convergence Out PWB from your TV and replace two IC chips. This will require a desoldering tool and some soldering experience. If you don't feel up to the task, perhaps you can remove the circuit board and take it to a local shop to repair. The Convergence Out PWB is removed from the front of the TV and is very easy to get at. Good Luck, Eric

      Hello, Sorry to bother you Eric, but could I also have the instructions? My email is: isajabroni@hotmail.com. My tv is model number: AV-65WP74, but looking at the JVC site the picture for model AV-48WP30 looks just like mine. I'm not sure if you know, but are there different instructions for my model? Even if the instructions aren't exactly the same, please still send me the info you have, any help would be appreciated. Thanks a lot!
