Question about Projection Televisions

1 Answer

I have a JVC av48wp30 tv with a convergence problem. I have read about changing the 2 stk392-110 ICs. Do I also need to change the resistor? Also, where can I get the schematics and instructions on how to make these fixes?

Double faces with red 'halo' around people...after TV 'popped' and went off then back on.


Replace the convergence ICs and resistors. You can get the JVC repair kit called the AV48WP30 - AV65wp30 convergence repair kit from www.tvrepairworld.com which contains the ICs, Resistors, and the CD with repair instructions.

Convergence is off on jvc av-56wp30


You will need to install a convergence repair kit which contains two Convergence ICs STK392-110 and then the associated resistors as usually a JVC will Need at least 1 or 2 of the resistors when the ICs fail. You can get the kit for your model at the following link which has the IC and all the resistors plus step by step detailed instructions on how to do the repair. This kit fits your model JVC

Was convergence problem now dont know


often on that model the DCU which is on that same board is where the problem is especially if new ICs and resistors dont fix the Issue. The DCU is the metal cased unit which is next to the Convergence ICs heatsinks

Convergence


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.

Convergence chips


The convergence IC or in a sense ,amplifiers and the resistor are output resistors... if they are burning up the current going through them is spiking too high... TO me this is an indication that the "convegence yokes" are shorted. These are coils around the tubes that control convergence. I would suspect maybe that these are shorted to ground somehow. This is my first guess for this problem
