Question about JVC Televison & Video

1 Answer

My JVC AV-48WP30 picture is distorted vertically to about half the screen height. If I turn the tv on and off a few times, sometimes it will correct itself, until I turn it off again.

Try resoldering the vertical output IC that should correct the issue repeated off and on cycles often tend to bridge the solder connection causeing the set to work untill power is cut off.

JVC AV-48WP30 problem starting up


The old video card has seen better days, methinks. All those symptoms lead one to conclude it needs a 'substitute' to enter the field, or call a long TV time out(too much pro and super bowl isms, eh?)..

Are you planning on doing this yourself?

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

JVC AV-48WP74 48 in.


The convergence circuit needs repaired. I did the same job yesterday on this model. I not only replaced the convergence ICs, but, I had to replace a couple of resistors and a coil. The convergence alignment was minor after that.
