Your convergence chip, or chips are gone. Easy to replace on this TV via front access panel. Remove the front speaker panel open up the access port and remove the front board. Get the IC's online and solder them in and replace, Make sure to check all of the resistors as they also blow and replace as needed. Make sure to use a good thermal paste like MX2 as this is the baser problem as to why these fail (you will see what I mean when you remove the chips)

    Additionally to my fix above, DO NOT REMOVE THE REAR PANEL.
    These TV's have a sort of self destruct issue with the dvi port if you open the rear of the TV without taking the proper precautions, and there is no need to do so when you replace the IC chips.

Double vision on tv with purple and green colors


Hello,

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...

Check that the 3 output plugs are in the right sockets (Red, Blue, Green) There is usually a felt pen colored mark on a white tape on the plug in wires. The Board sockets are marked Red, Green, Blue.

Screen is bowed (top and bottom) Color has a green and purple tint?


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.

JVC AV-56WP74 projection TV green sagging and can not be adjusted out.


The convergence amps need to be replaced. If you're having a shop do this call around and ask what they charge for repairing the convergence. If you're doing this repair this set uses two stk392-110 Sanyo built amps. You will also need to test and possibly replace one or more of the 1.5 ohm feed resistors in that circuit.
If you're doing this at component level try Acme in Florida for amps and resistors: 1-800-575-9833 http://www.acme-sales.net/index.shtml and if you're doing this at modular level send it to PTS http://www.ptscorp.com/ 1-800-844-7871
Good luck!
