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.

Our $2700 less than 3 year old Sony LCD KDL-40XBR5 did the same thing 2 weeks ago. Sony was anything but helpful. They said to take it to a repair shop or we could send them $550 and they would replace it with a $800 set. Repairman says that it is a panel and the part has been discontinued by Sony. The 46" sets had the same problem and were recalled but not the 40" screen. We stopped on the way home and purchased a 40"

Hi, The
Standby/Power light of the TV blinks when there is any internal malfunction in
the TV. The self-diagnostic function of the TV will cause the STANDBY light to
blink or flash when the television detects an issue. The number of times the
STANDBY light flashes corresponds to a specific issue. Few
examples are given below; some of the issues may be resolved without the need
for service. If
the television is plugged into a power strip or surge protector, remove it from
the power strip or surge protector and plug it directly into the wall outlet.
If the issue is resolved, the problem is with the power strip or surge
protector and not the television. If
the issue continues to occur, service may be required. Thanks
for using Fixya.
1 blink / 2 blinks / 5 blinks: - This indicates that there may be a
power-related problem with your set.
3 blinks: - This indicates that there may be a power-related problem with your
set. The set will need to be serviced to allow a technician to determine the
specific issue that needs to be repaired. If the power light flashes three
times in sequence in a Lamp TV, the lamp cover is not securely attached.
Reattach the lamp cover to resolve this issue.
4 blinks: - This indicates that there may be a back light or lamp power
problem.
6 blinks: - This indicates that there is some kind of audio problem with your
set.
7 blinks: - This indicates that there is a temperature problem with your set.
Please check to make sure that the air vents on the sides and back of the set
are not blocked or clogged and there is adequate ventilation around the
television. We recommend that you check and clean the vents periodically to
make sure the set receives adequate air flow. If the problem continues, the set
will need to be serviced.
8 blinks: - This indicates that there may be a video-related problem with your
set. If the flash sequence is not listed above or the light continues to flash,
follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
