have the power supply checked out

your red tube is going out

use your convergence controls on the remote

your power supply may be weak

tv needs to be converged

This model is full of problems, I had the same reapir done abput 2 years ago and now my convergence is shot. either fix it yourself or throw it out!

It was such a nice tv while it worked.

you will need two convergence ICs they are both STK392-110 you will also need the JVC convergence resistor Kit #1 the parts are available at the following link and they provide free step by step instructions with pictures so you can do the repair yourself.
Heres the link.

did you replace the convergence resistors with the ICs? The resistors often get increased resistance when the ICs go out and if they dont get replaced you can have a next to impossible time adjusting the convergence properly, as they have to be within 5% tolerance. You can get the resistor kit for your JVC at the following link. Its Called JVC convergence resistor kit #1. Heres the link.

You need to replace the two Convergence amp ICs they are both STK392-110 thats a easy reapir on that model , But dont remove the rear panel with the power cord plugged in you will destroy the digital circuits. the Ics are up front behind the speaker grille. You can get new replacement Ics at the following link with free instaltion instructions with pictures. Here's the link,

Did you have the back of the tv open while the poer plug was plugged into the wall? If so the set will need some serious repairs as that model has a safety feature where if the back cover is removed without removing the plug from the wall it wipes out all the digital and video circuits. You have to defeat the safety feature before removing the back panel, and if you plug it in even for a second with the back removed the damage is done.

You can get replacement ICs at the following link and they provide free instructions with pictures and also have free instant messageing with a tech online to help talk you through the repair. Its an easy inexspensive repair less tahn 40 dollars for both the new Ics and instructions and the tech support are free heres the link.

not unless you damaged the board, & theres no part of it have to be soldered and circuit is damaged, then it could be needed a new board.. but try to check if theres something to correct into your soldered parts and correct it again using a soldered pump to remove the bad solder.

thanks

check the resistors right next to the ICs usually the 1.5ohm resistors will open when the ICs go out

You need to replace the convergence ICs numbers STK392-110 you will need to replace both ICs you can get replacement ICs at the following link and they provide free instalation instructions with pics so you can do the repair yourself and save about 400.00 Heres the link.
