Hitachi 50gx30B Pincushion problem

Hey Guys,
I have replaced the SK convergence IC's (both) on my 50gx30b I followed the instructions and did not replace the resistor because none of them were discolored. However when I repowered the TV I noticed the green was pincushioned. I went in to the service mode and adjust the beams to the grid and the color has lined up but now I have all the colors pincushion. When I shut the tv down for any period of time the Red and Blue does not stay aligned and I have to go back to the service mode to correct the issues all over again.

Please let me know in which direction the picture is distorted. Does it bow in from the top and bottom or left and right?

Thanks,
Dan

    Thanks for the update. Yes that is a pincushion problem that is not related to the convergence parts that you replaced. I will look up your specific model to supply you with the parts in the pincushion circuit.

MY HITACHI 50GX30B HAD BLURRY VISION LIKE


Sounds like the convergence board, try replacing the STK voltage regulators and any resistors that may burned or discolored. This problem is causing the power supply to shut down probably.

JVC av56wp74 IC CHIP


you can get the replacement STK392-110 Ics and the JVC convergence resistor kit #1 at the following link which has the complete step by step instructions with pictures so you can easially do it yourself. You will need the resistors also as JVC will definately blow one or two resistors minimum when the Ics fail. Heres the link.

Which IC is for red convergence?


you need to replace both because they are both linked together with the green as each IC controls one color fully and half the green, so when one IC fails that places a strain on the other IC through the green, so that one will soon follow. You need two STK392-120 ICs and you will also need four 6.8 ohm 1 watt resistors. You can get replacement ICs and resistors at the following link with free installation instructions with pictures so you can do the repair yourself. Heres the link.
