The ICs are located on the D board Tan board on the lower left side looking in from the rear. They old Ics will need to be desoldered and replacements soldered in. Also check the yellow pico fuses located under the fins of the ICs heat sink, usually some of those will be open ( Blown) replace them with 3.5 amp pico fuses.

Convergence


If you can not adjust the convergence, then you need to change the convergence IC's The number of the IC is on the chip. There maybe one or two IC chips. I think there are about 12 to 15 pins or so, and will be mounted to a heat sink. There maybe surrounding resistors that need to be replaced too. I hope this is helpful.

its far more likely that you need a new Vertical output IC. The convergence ICs wouldnt prevent the picture. When you have audio but no video it is often meaning vertical failure. Try replaceing the vertical IC

42H83 Convergence


Yes the convergence ICs need to be replaced, however so dont the six 1.8 ohm 1watt resistors as Toshiba recomends replacing those six resistors when the ICs are changed. You can get the 50H71 / 50H82 Convergence repair kit as the 42H83 is identical to the 50H71 series, so the kit will work for your model. Heres the link where you can get the kit.

Right side convergence


A convergence IC has burned out. If I remember correctly, those Pioneer sets have one huge convergence IC, but that IC only has 5 channels in it so they use another smaller dual STK IC and one half of it is used for the 6th channel and the other half is the vertical output. Look on the convergence board, find the blue convergence jack, identify the blue horizontal channel, follow the traces and replace the IC handling the blue horizontal channel.
