Sony model kp57ws510 rear projection. convergence problem. convergence button on front of tv does nothing


There are a set of convergece chips that need to be replaced. If they have been replaced and you still have the convergence problem you will need to change ceramic fuses in the power supply or on the board where the STK chips are located

1st off the convergence is digital on these units when it takes a major change it means there is a hard ware failure
there are a two ics and some resistors that usualy need replacing
adjustments there made through the consumer menu.
adjustments in the service menus are for touch up or a corrupt DCU thats failed and needs to be reset up and the centering magnets on yokes are set for sharpest ctr point of focus .

The only items on your set that should need replacement would be both convergence IC IC801 and IC802 which are both STK392-570 and you will also need to change the two 5 Amp pico fuses which are F9A04 and F9A05 they are both % amp pico fuses. All parts are located on the center Board

Help, Help, Help! Mitsubishi 73" red convergence fiasco


Thats the time you need to replaced the convergence IC.
Just click below for convergence repair kit;

Double images and colors are blurry and fuzzy images .Blue,red and yellow wave coming up from the bottom of the screen on the lower left and cannot be adjusted this is the symptom for busted convergence IC,you must replaced this IC in order that will works better again.STK 392-xxx ICs and it's associated resistor,this resistor automatically change value,can caused truoble even though you change the ICs.If you bring this to a service center they cost you $600 to $700,but if you buy the repair kit you can save more,don't wory it is very easy because there is intallation guide including in the repair kit. Feel free to ask whatever the result... click the link for sample picture guide step by step installation;

Hope this may help;

I'm experiencing different colors on the tv when displaying an image.


If these colors appear to be like a 3-D image, the problem is in the convergence circuit. Please update this with the make and model and I will provide you with further information and instructions.

Thanks,
Dan

I would change all convergence IC not just the one that holds the red. You will need the schematic to get the resistors location.
