4 blinks on a Sony Bravia indicates a backlight/inverter (aka ballast) problem. These ballasts are regrettably only available with an entire LCD panel. :( You may perchance be able to find a parts outfitter online that scraps out TVs and have a used ballast.
Typical backlight problem on an LCD shows up as the screen lighting up for a second or two and going back off. The 4 blinks just confirms your problem.
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.
