av56wp74? This is a fairly easy repair if you know how to solder---most of these sets use two convergence chips---I can tell you how to do it--you will need two new chips and maybe a resistor or two--sometimes the chips damage a resistor around them--this set is a easy fix--look in your area for someone who will do it in your home--I do hundreds of them here for 200-250 total--if you want to know what is involved to do it yourself--give me a vote here and I will tell you.

Red lines all over the screen


this set(AV56wp74) was first made in 2003----if you use the remote for the set and go into the customer menu---select convergence----once there see if the red and blue will move left/right and up/down----if either color will not move in any one of these directions----you have a bad convergence IC--this set uses 2 of the STK-392-110 output ic chips---both need to be replaced and the set adjusted with the original JVC remote control. I hope this has been helpful.

1. disassemble front speaker panel.

2. locate circuit board in front with the 2 large black or silver heat sinks standing up. (this is your convergence board).

3. disconnect all the wires on this small board, but make sure you take a picture first to know where they all go.

4. look for 2 black cips that says stk ***-***.

5. order replacement chips on line.

6. learn to solder before chips get to you home.

7. watch you tube videos titled "how to fix tv convergence.

I have a JVC AV-48WP30, and I had a lot of issues w/ red lines appearing on my screen. If your problem is like mine, then you have to find the video processor, which is a small, squarish metal box on the main board right behind where the a/v plugs are on the back, and jiggle it a little bit, maybe stick a zip tie on there. That always made my lines disappear.
