Question about JVC AV-56WP74 56" Rear Projection HDTV-Ready Television

1 Answer

Jvc Our current problem with our television is that our blue and red lines arent lining up and we can seem to get them to. We've been under setting a number of times and we've done manual set up and automatic set up and no luck!! We even got in the tv and cleaned the bulbs. See we live for tv (I have a child) and double vision, I guess you could call it, is giving us an uncontrolable headache! So if there is anything you can do please let us know what it is!

    The blue/red colors do not line up, I have tried the convergence on auto and manual settings. I have tried super focus and nothing worked. The double vision is messing with our minds...please help!

Well there is no yellow, there is only red, blue and green, Blue is the set line the other 2 need to be aligned to. If blue is bent or out of alignment then there is a problem with some internal chips that would require a good deal of soldering skill

Screen is red with lines when channel is changed


If its a kp-51hw40 : go to an unused video input and look at the screen---if it is redish in the background with curved faint trace lines you have one of two things wrong; First: the red "screen" control may be set too high. Second: you may have a problem with the RED picture tube.


To try to adjust the RED screen down you have to remove the entire front grill plate on the front of the TV(some have screws on the back on either side that have to be removed---and then you should be able to pop it out. Behind it there is a masonite inspection plate held in with screws----Once you have that off look for a SMALL SQUARE BLACK PLASTIC BLOCK; it has 6 black adjustable controls---you have to use a flashlight and look carefully---one row left to right will be marked FOCUS--DON'T TOUCH THOSE---THE OTHER ROW left to right will be marked SCREEN; if you look carefully you will see marked by each r (red) g (Green) b (blue)
you want to locate the RED SCREEN CONTROL.

WITH the set still on a blank video input where you can see it clearly turn the RED Screen Control to the left until the lines and red tint go away---do this slowly and make sure you are adjusting the RED screen--not the FOCUS.


IF this has been helpful give me a vote here as I do this for free; yesterday I adjusted one of these in a home that was blue with the faint lines---about 15 minute job for me.

JVC AV 56WP74 Problem after fix


Will the colors move into alignment controlling them manually?
If you can get the colors to align but they simply won't hold it's a matter of programming. If they won't align you still have a failure in the convergence circuit. If red or blue will only move so far but not close enough to align you have an amp problem.

Mike, convergence adjustments are in your menu, usually under "video" settings. You have to adjust red & blue onto the green, when you`ve done it correctly the "cross" will be pure white, if you cannot move either of the colors left, right, & up, down then the convergence IC`s have failed and will have to be replaced, hope this answers your question, BMW Rider
