Question about JVC AV-56WP74 56" Rear Projection HDTV-Ready Television
Double exposure and curve
Convergence is most likely for this model------that circuit in this set is right at front behind grill below the screen.
If you can solder it is a do it yourself type repair with parts under 30 dollars (most shops get 250 average parts and labor) and I can tell you how to get that board out and what is needed.
Here is the board removed from a set.

No. You have bad convergence output ic;s and probably at least 1 burnt resistor. This liely will have to be reconvergec in the servcie menu after the aprts are changed.

This television set, as well as most rear-projections, is prone to convergence driver problems. There are two large chips (STK392-110's) in the TV that need to be replaced, as well as some resistors that are likely damaged as well. Any competent TV repair shops should be able to repair this TV for 200-300 dollars. It is important to note that if the back of the TV is taken off without the proper prep., the Digital input (DVI) will be disabled permanently.
Hope this helps you...

This kind of picture problem is due to failure of convergence out ICs, please replace convergence out ICs in tv to get it fixed.
If you are handy with electronics stuff repair and can replace parts in circuit board with proper tools then can replace above said ICs by yourself or ask local tv tech to repair your tv.
