SOURCE: Standby LED blinks 4 times
Hi there,
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.

If the Standby light is blinking at the front panel of the TV, it seems that there is an internal malfunction occurred in the TV. I will forward a link to a page where you can get more information and troubleshooting steps for this issue. http://www.kb.sony.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=C399467 Please perform the steps provided on the page. If the issue still persists then service of the TV is required.

This is either your LCD backlight, inverter/power board or both. Neither of which are serviceable by the consumer, unless a visual inspection of the power board shows swollen or ruptured capacitors. This you can do yourself and is the most likely problem. Just read the side of the capacitor and go to radio shack, or online to find the right replacement capacitor. When re soldering be sure your negative and positive leads are in the correct holes.

there is a overload problem, normaly is inverter board is broken, needs to be checked, by tech.
If
the TV does not go into standby press the TV button then the standby
button, then TV then standby, keep repeating this until successful. This
will scan the codes used for a particular make of TV.
Please keep me posted.
Thanks.
