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

Convergence problem

Hello,

Did you lock the adjustment into the TV's memory? This step is the most often missed. Please follow the directions on the Users manual or on the service manual on how to set your memory to hold the configuration.

Find the menu item on setting the convergence adjustment into memory (the menu should have an informational screen on this topic)

I hope this helps

Thank you,

Jvc 56wp74

sounds like a solder related issue on the convergence ICs. They are acessed through the front of the TV behind the speaker grille and then remove the small acess panel and you will see the convergence amp board with the two ICs on it.

Convergence problem with my jvc tv

Its actually a easy repair but its recommended that the convergence resistors need replacement as well. You can get the parts at the following link and they provide free detailed instructions with pictures. You need two STK392-110 Convergence ICs and you would need the JVC convergence Resistor kit #1 also. Heres the link.

A repair facility will charge 400 to 600.00 for the repair. Or you can repair it yourself if you can solder. As both convergence ICs need to be replaced. They are STK392-110 you can get replacement ICs at the following link with free instalation instructions with pictures so you can do the repair yourself. Heres the link.

JVC projection tv

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

Convergence problem

I have this exact model TV, and my red bulb was the primary culprit. I almost had it, but then a lot of fluid came from underneath the bulb? I had to turn it off in fear of electricution. Ended up selling the TV.
