This is what I have on file --- Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly. --- On Mon, 11/23/09, Mike Schoettinger <kc8lqu@xxxxxxxxxxx> wrote: From: Mike Schoettinger <kc8lqu@xxxxxxxxxxx> Subject: [tvservice] Sony KP-46Wt510 To: tv_repair_help@xxxxxxxxxxxxx, tvservice@xxxxxxxxxxxxx Date: Monday, November 23, 2009, 10:01 PM Hi All, I am still working on this POS Sony model kp46-wt510. It is really throwing me for a loop. It came in with a blown power supply and stk's. I have replaced the power supply and the STK392-560 with the stk392-570. The problem I am having now is it is blinking 5 times. I get a picture and sound but the picture isn't good. All the whites have a green shade to them. All the power supply voltages are good going to the Stk's. When I do the zoom feature it also distorts the picture even more and makes it bowed. I have been working on tv's for about 5 years now and I have done quite a few hitachi's, JVC, and samsung but this one has got me. Any help would be greatly appreciated. Thanks. Sincerely, Mike Windows 7: I wanted simpler, now it's simpler. I'm a rock star.
