I HAVE A JVC AV-48WP74 48 IN. TV AND THE CONVERGENCE IS CREATING A DOULBLE PITURE WITH THE RED COLOR IF I TURN THE RED LAMP ALL THE WAY DOWN IT FIXES THE DOULBLE PITURE ,BUT THEN I HAVE NO RED IN THE COLOR DOES ANYBODY NO HOW TO FIX IT.SUPER FOCUS WONT FIX IT AND THE MANUAL CONVERGENCE ON THE REMOTE CONTROL WONT MOVE ANYTHING ANYMORE.
I had a problem with my TV colors not lining up. One day I turned it on and the green was out of wack. I checked this message board and replaced the STK chips, bad soldering and all led to me just giving up on that and buying a whole new Convergence Board ($185). I just plugged this in and though now my Green lines up okay, my red is out of whack. Is there something I am doing wrong?
Can anyone help me? Did i miss a step? Frustrated......Bruce

Ur tv have a problems known as a convergence problems,it dead.The tv have colors lines R,B,G mis alignments,have colors shadows pictures or 3D picture look alike?The tv convergence board it is dead.The tv convergence board,must require repalcing 2 STK convergence ICS and some or all of it resistors too.The tv convergence board is fix,will solved ur tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.
The tv 100% have a convergence problems,it dead.Tv have colors lines R,G,B mis alignments,have colors picture shadows or 3D pictures look alike?The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors are dead too.These parts on the tv convergence board,must be replaced to solved the tv convergence picture problems.The shop,will cost u like $300-350 for parts and labors.
The convergence ICs have failed. You can get the JVC AV48WP74 - AV65WP74 convergence repair kit from www.tvrepairworld.com which has the ICs and resistors plus the CD with detailed repair instructions.
Tv colors R,G,B don't alignment any colors.Tv have a convergence problems,it dead.Tv convergence board require changes 2 STK convergence ICS and some or all it resitors to solved convergence problems.The shop will cost u $300-350 for parts and labors.
If the convergence Ics and resistors are good its most likely related to the velocity boards that are attached to the Red CRT convergence yoke. Its the small board about half way up the neck of the CRT. If you need one let me know as I have a source for JVC boards for that model.
