Question about Projection Televisions
The Tv is about 5 years old and has developed red drooping lines at times with red lettering.. presume this is a red convergence problem, but I am no expert If the convergence is controlled by a chip (IC) I am experinced enough to change out the chip whether the chip is a push in or soldered on the main board as long as it does not require test equipment following installation. I do not have a schematic but hopefully there might be one inside the back cover. If this is possible where can I buy the IC from !! not being in the trade Can anyone help, comments. Thank you
Replace both STK392-040 convergence IC's with OEM or better
quality = I use Panasonic with great success. They are soldered
in and requires at least PCB removal or perhaps entire chassis.
Please post response if you need more help...................T

Hi. Depending on how bad the red convergence gone out you may not need any spare parts. You did not say that you have entered the normal menu & adjusted the convergence. If you havent adjusted the convergence which you should do a couple of times a year go in to the normal menu go to convergence & set it up. If it wont set up then you do have a problem & will need new ICs fitted.
