Question about JVC AV-56WP30 56" Rear Projection Television

1 Answer

Hi Joe, av 56wp30 Question

Could you confirm for me the value of the resistor r 846 on the convergence board? I have the other two which are both 2.2 ohm, 2 watts, but I believe r 846 is 1.5 ohm, 2 watts.

(I'm replacing R 850, R 846, and R 842)

My email is storyboardninja@yahoo.com

Thanks

Drew

    Hi, I have a similar question. I need to replace R-862 when I replace the STK chips. It is currently reading "open". I believe it is a 1.5 ohm but can't tell for sure as it is charred a bit. Is this some sort of fusi-resistor or just a regular resistor and where can I get one?

If auto convergence does not work in the menu then replace the convergence ICs and check resistors around it. You can take the grill off the front and access the convergence board fron the front. Its a small board to the right and it is removable. Do auto convergence again after replacement.

Red convergence will not line up on my jvc 56 inch i art projection tv model # AV-56WP74. PLEASE TELL ME WHERE CAN I BUY THE KIT SO I CAN FIX IT MYSELF!!!


You need to pull the front grill cover/panel off the front of the tv. Remove screws (4) from back that hold it on, also 2 small ones behind front video input door. Then remove access panel. The ckt board closest to you is the convergence amplifier board. You should replace both amplifiers (stk392-110 or 120) and any burnt/open resistors you find near the amps.(use the same value resistors as the corresponding resistors in the blue amp ckt)

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

Jvc 56wp30


1st guess is bad convergence ic-either IC804 or IC805. Both are part #STK392-110. May be bad connections in convergence circuit, or open resistor(s) As for too much green, not sure, shouldn't be because of convergenece circuit, possibly green CRT screen voltage needs adjustment.
