It needs to be serviced. Bad caps, resistors, & possibly a transistor or two. Not an unbearable repair, but you can count on it being 100-175 depending on the shop. You followed all the troubleshooting you could without opening the unit.

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.
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.
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.

Hello
Standby light blinking is a fault indication in Sony sets. You just count the exact number of blinks at one time, after switching on and off the set by its front panel power control switch, NOT BY THE REMOTE CONTROL HANSET. Just inform me the exact number of blinks occur there, after counting it at least four times. It will help me to reach the faulty stage, of sometimes to the exact fault location also. OK.

get a new TV :)

There is some electronic circuit problem with your TV. Best if you want to repair it you find a reputable TV repair shop. Sorry.

What to do: if you have a solid amber light If the power light on the box will not change from solid Amber to solid Red then it is possible that a problem has occurred with the current in use software. Before attempting a fix, power the box off and on at the power socket and then wait at least 5 minutes for the solid RED lamp to appear.
If it still remains solid Amber and the box will not come out of standby to ON (Green light) then this can be corrected using the software revert procedure which is done using the box front panel buttons as follows:

1. Remove power to the unit by removing the power cable from the back of the box.

2. Wait 20 seconds and then restore the power cable while pressing the standby button repeatedly on the front panel of the box.

3. Release the standby button immediately when you see a lamp flash on the box's front display, and then immediately press the following front panel arrow buttons in this sequence:

- Menu
- OK

Note: you have to do this quickly and in sequence

4.The Orange light will flash and the STB will then reboot and should return with the previous version of software.

5. The box will now be running with the previous software version but it will automatically update with the latest version within approx 2 hours and you will be notified by message which will appear in the Message area within the Main Menu.

If you're still having problems please call 08444 159 159 and a member of the Technical Team will be happy to help.

The flashes are a diagnostic. It should be only one flash pattern, either a 5 or a 10 (there are several other patterns in between as well). Please verify the number of flashes after power on, several times, and post back here, and I will be able to help with the fix. Based on your initial description, it my be the HV distribution.

The standby light blinks 5 times

TURN TIMER OFF. GO TO SONY.COM, TROUBLESHOOTING, OR The STANDBY light is flashing on the television and there is no picture or sound. Solution
The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.

1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
   
2. Unplug the television power cord from the electrical outlet.
3. Let the television remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. NOTE: 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.
   
5. Turn on the television.

If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center.
