    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.

Convergence


It depends on what kind of convergence problem you got & what kind of universal remote you are using. If you mean aligning the crossline some
universal remote can be used to align the colors & on most TV you don't have to save it. Otherwise it will tell you what to do. If you are talking about aligning the convergence by accessing the service menu, you need the original remote control. Of coures this procedure is ONLY for the experience
technician. Good luck. AstroTech

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.

Convergence


Touch-up Convergence adjustments Enter the Digital Convergence Mode (DCM) by entering 0-6-2-5-9-7-(Status or Index) on the Remote control. The following menu will appear: Select an active channel or Aux Input. A signal must be applied to the set when performing convergence. If any Customer Adjustments need to be made, the Menu button can be used to toggle between the Customer Menu and DCM. The MPOSD ADJUST is used to center the Customer Convergence grid. A highlighted cross will appear along with the Convergence alignment grid. The highlighted cross should be centered onto the center of the Convergence grid. To perform a Touch Up Convergence, highlight SELECTION and press the right cursor button on the remote. The following menu will appear: Selections STORE, RESTORE FACTORY, and RESTORE DEFAULT are not shown after selecting SELECTION. Press the cursor down button on the Remote for these selections to appear. RESTORE FACTORY loads Convergence defaults from the Factory Loaded section of the Convergence Memory IC. RESTORE DEFAULT loads Convergence defaults from the sets software. To perform a Touch-up Convergence: 1. Enter the Convergence Mode and select RED TO GREEN or BLUE TO GREEN. Do not select GREEN (Green Geometry) without placing a Template over the screen. To perform Green Geometry, refer to the Complete in-depth Convergence. 2. Use the Cursor buttons on the Remote to Navigate from one adjustment point to another. Press the Status or Index button on the Remote to select ADJUST. Use the cursor buttons on the Remote to adjust the Red to Green or Blue to Green. Press the Status or Index button again to navigate to the next adjustment location. 3. After Convergence alignments are complete, press the Menu button on the Remote to return to the SELECTION menu. 4. Highlight the STORE selection and press the right cursor key on the Remote to save changes. 5. Use the GREEN TO RED or GREEN TO BLUE selections to perform convergence when the Green CRT has been replaced.
