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

1 Answer

JVC av56wp74 red lines won't converge. How can I fix it myself. I have seen that a few people have done it themselves, wondering if I can get some info on how much parts cost and if It is the chip is the problem I have head about. Some step by step instructions would be a huge help and where to find parts online also.

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.

8. wa, la send me some money to show me your appreciation, lol.

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.

JVC av56wp74 IC CHIP


you can get the replacement STK392-110 Ics and the JVC convergence resistor kit #1 at the following link which has the complete step by step instructions with pictures so you can easially do it yourself. You will need the resistors also as JVC will definately blow one or two resistors minimum when the Ics fail. Heres the link.

Bad convergence on my jvc model av56wp74


If you can solder and you are comfortable working inside a set where there are potentially dangerous high voltages, yes you can fix this. The problem is likely to be either bad connections on the convergence ICs or defective ICs. If you still have the results of the previous repair, please post those here and I'll provide you with additional details and instructions.
