Philips Blue Shadowing


If you have not already done so go into the picture menu and set the convergence. The convergence is the angle at which the three picture tubes meat at a given distance. The tv will have at least 3 and up to 64 convergence points, and those 64 can be set for all three colors. This can be tiresome but I'll be it will solve your problem. What your trying to do is get the color in the cross-hair so you cannot see the color behind the target. On top of the fine setting for each point and color you will probably have 3 gross adujustments for blue and green and maybe red. These adjustments will affect positioning, like what you are discribing. You should do this at least every month, the thermal cycleing of the lamps is what will cause this to creep out of adjustment.

Sony KP53S35 blue projector problem


You need to replace both convergence ICs. They are STK392-110 they are located on the g Board on big heat sinks designated as IC809 and IC810. You can get new replacement ICs at the following link and they provide free unstalation instructions with pictures plus free on line tech support. here is the link. If you cant access the site right away try again cause they get super busy in the evening with customers placing orders.

Blurred picture


Sounds like a resistor in the convergence circuits or covergence amp ICs them selves. Usually the ICs will distort the picture. My guess would be the flame proof resistors near the ICs 1 or 2 may be oen. Let me know if you need anything further.
