Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206. For more information go to http://electronicshelponline.blogspot.com/
a picture that blinks in & out every few seconds then it could be a bad tube. I know the older models the picture would flash in and out with snow etc. that was a tuner problem. haven't worked on very many sony wega's, maybe another tech here has a better ans.
IT SOUNDS LIKE THE VERTICAL I.C. NEEDS SOLDERING. WHEN IT LOOSES THE PICTURE DOES IT HAVE ERROR CODE 2 ? THE RED LED BLINKING 2 THEN 2 THEN 2. THAT IS LOSS OF VERTICAL. IF YOU SMACK THE SIDE OF THE SET.(NOT TO HARD) WITH OPEN PALM ON LOWER BACK IF THE PICTURE COMES BACK IT IS THE VERTICAL IC THAT NEEDS TO BEE SOLDERED. DON.
ON THE 36 INCH SONY THE PROBLEM LIES ON THE PICTURE TUBE.THERE IS A LEAKAGE EITHER HEATER TO CATHODE OR G1 INSIDE THE CRT.THE ONLY WAY TO FIX IT IS REPLACE THE CRT OR HAVE THE CRT GUNS CLEANED THRU PICTURE TUBE TESTER/RESTORER/REJUVINATOR AVAILABLE ONLY FROM TV TECHNICIANS.GOOD LUCK.4TUNE.
Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://homenol.blogspot.com/ http://electronicshelponline.blogspot.com/
If blinks continue without any pause, the main board is faulty.

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 Cboard, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking.
