Most likely the two stk-392-110 convergence chips are bad and need replacing, several sites sell kits for this.
Jvc tv has 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.
Why is the blue light on front blinking
My answer is based on the model number here-AV-56WP74 or similar--blue light blinking is shutdown to protect the power supply in the set.A few questions you could answer:before this happened was screen red (too much) or had colors skewed or a little 3d looking?The most common issue on this set if that is convergence and it can easily escalate to where it shuts the set down and blue blinks constant.There is a simple way to confirm or deny that issue--Got someone willing to try that?

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.
Purchased this 56" projection TV
You can get it repaired. Its maybe a resistor/s thats losing its value and needs to be replaced.
You can locate this on the mother board close to the or near to the Fly-back transformer section.
Good luck.

If the red line looks like a swoosh of red across the screen it may be the convergence Ic having an issue.
