SOURCE: i have a rear projection

From what you have said , Replace both of your STK ICs they are big black ICs will have part number on them example STK392-110
Go by the number printed on them if they are 110s use the 180s they are better ICs Mats has them for $10.95 each 1-800-628-1118

Also go to this website/use Google Encompass Parts Distrubtion
1-800-638-3328 sometimes they will have free service manuals you can print out.

Another thing you need to CK pico fuses they will look like resistors only they are green or yellow 5amp/ 6amp fuses Look in front of ICs and some are located behind ICs.

My sony tv stars blinking 5 times in a row, then the picture goes black for a second comes back then goes black again and it keeps doing it non stop


tv has a blanking picture mute circuit. adjust the screen controls which are located behind the speaker grill in front of set. there will be a access panel to unscrew in center and then you will see a black 4 inch square box with 6 physical knobs. 3 control screen the other 3 controls focus for red, green, blue. turn them down and slowly start turning them up. fixed.

Usually this means convergence ic's have to be replaced and possibly a few resistors on small convergence board. Sometimes it requires digital alignment after new parts are soldered in. This repair can cost 175.00-375.00.

the RGB focus / screen adjust block....turn RGB screen controls
SLIGHTLY clockwise to achieve more brightness....not too much

Blue arc


There are 2 large convergence IC's and the one that handles Blue Vertical (BV) has burned out and needs to be replaced. This is by far the most common failure in those projection sets. It is a good idea to go ahead and replace both STK392-110 IC's with the newer improved STK392-150's. If you have never replaced convergence IC's and realigned convergence circuits then have a qualified tech handle it for you.
