    My JVC-56wp30 has had the convergence repaired 2 times and each time it has lasted about a year and then it needs another 3-4 hundred to repair it. I have the original remote and have followed the instructions to adjust it but it will not work. What is the part that the techs have been upgrading and replacing? Can I purchase it and change it myself or can I adjust something to get it back going?

The two convergence ICs labeled STK392-110 are bad . Likely the resistors that go with them one or more are bad too.
If you have patience can use a ohm meter, solder properly and have good vision. You can fix this problem .
Parts can be found at www.eletronix.com . Good luck, maicomasher

You can but you need a good universal remote not a cheap 20 dollar one look very hard online and you can find some that download via usb from your computer for pretty cheap. mine at best buy was 130.00 i got it online for just under 40.00 but i had to search does your tv not have an automatic convergence button on the front

Can you use a universal remote to do the convergence on a hitachi 50vs69a tv?


No, but almost any hitachi remote will do that--problem is on different remotes different buttons do different things in the digital convergence mode.

Can a hitachi convergence be fixed without a remote? seems like red is adjustable, but cannot access the blue line with our universal remote


Ur universal remote was able to move - + from the convergence grid wright,it is a good remote.The tv convergence board is dead.The tv convergence board the 2 STK convergence ICS and some or all of it resistors are dead too.These parts must be replaced on the tv convergence board to solved the tv pictures convergence problems.The shop,will cost u like $300-350 for parts and labors.

Convergence without a remote control


you will need the origional remote you can get one fast through this link just enter the model number www.replacementremotes.com
its normal after an IC change for the convergence to need adjusting, universal remotes can sometimes do it, but i have only seen that happen once or twice usually they wont have the right feature to adjust then save the settings.
