I have this problem as well. My wife and I were watching the TV one night and the screen went out. Upon trying to restart the TV, the stand by light flashes 4 times and the TV never starts up. This model was built in 2004.

What's your problem?Hi, I have a Sony projection TV KP-46WT510 theres no picture or sound, but it still turns on and I can see the the on screen menu. When I turn it on the led blinks four times

You can Google and find the service manual which will explain what the 4 blinks means.

If you have the Sony remote with the set off:

Display, 5, Volume down, Power

If the set has it you will see a box appear on screen with a list of items--all should have a zero to the right of each---one with a number indicates the number of times that error has been detected.

Let me know if you have questions or cannot find what the four means and I will research it.

Hello, I have a Sony Projection Television Model number KP-46WT510. The problem I am having is when I turn it on it turns back off. The standby /timer light blinks six times. What could be possible...

Low B over voltage or over current shutdown its usually related to either the A board or the B board. You can get the replacement A board which includes the B board from www.tvrepairworld.com

Try to turn on, it turns off right away and the stand by light flashes 6 times

Hi

Thanks for using FixYa. Standby/Timer light blinking 6 Times means no Horizontal (H STOP), no raster, and so the set goes to the blinking self-diagnosis function immediately. You’ll need to open the back off the TV and check C515 & 516 and the jungle IC, IC206. Also check +5 line is overloaded (A, B boards), +5 line is shorted (A, B boards). Please do rate the solution if the issue is resolved or post a comment for further assistance.

Thanks
Rylee

When i turn the TV on, a red light on the front of the set just flashes (standby light)

Let me know model and brand of TV if its other then Sony KP-46WT510 and also count red standby light flashes as there would be long pause between blinks.
These info will help me to find out possible solution.

6 bliks on sony kp-46wt510

KP46WT510 Shutdown 6 Blinks. 6 Blinks = Low B+ OCP/OVP
SOLUTION: Replaced Flyback transformer. It had no rings on the ringer test.
HQ
Comments: Any load on the B+ line can cause 6 Blinks.
Example: If the 200v line is loaded down will cause a drop in B+ due to bright picture current demand.
