JVC AV-48WP30 , how to change convergence

I have had the convergence changed on my JVC 3 times and they are out again. Instead of paying 300 to have a shop replace them I was attempting to change them myself. I have never worked on a television before so i was looking for step by step instruction hopefully with some pictures as well.

First of all tools,requirement to do the work on the Convergence board to do changes the 2 STK convergence ICS and some or all it resistors.U have a soldering iron,desoldering pump or soldering wicks and solders?Don't?must buy to do desoldering and soldering?Tries Amazon.com to buy solders.Tries wesites like Tvrepairworld.com to buy the convergence kit to replaced ur self,and buy the soldering iron here it have the desoldering pump attach to the sodering iron it self.For video tutoring how to take out convergence board out of the tv and replacing the 2 STK covergence ICS and some or all it resistors.Might included in the buying of the convergence kit,not,Try You Tube type in convergence problems,will have video some body doing it.

Check convergence adjust screen after picture distorts.

Description sounds like shading from a defective convergence circuit. If you replaced STK392-110 with 150, then re-install new 110's, or new 150's and re-design the circuit and change low-ohm resistor values to compensate for different IC's. It is not the same as a brighter light bulb.

See if the picture is in the CONVERGENCE GALLERY

If the convergence Ics and resistors are good its most likely related to the velocity boards that are attached to the Red CRT convergence yoke. Its the small board about half way up the neck of the CRT. If you need one let me know as I have a source for JVC boards for that model.

Jvc av-48wp30 convergence problem


1. if the 1.5 ohm resistor was open, then you may have fried your new convergence ic's. Sorry
2. bettween a 1.5 - 1.9 ohm resistor will work
3. press sleep button, set to 30
hold down video status button and press display on remote
select convergence from the new menu and hit OK.
Do fix the convergence before you try to align the convergence or it will look horrible after you get the circuit fixed and will be harder to align.

The white button is there because the DCU (digital convergence unit) can be erased by holding that button and turning the set on.
I WOULD NOT RECOMEND THAT AT ALL!!!!!!!!!!!

Hope this Helps.
