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.
Thats a deflection board issue which has shut the CRTs down the menu pops up so its most likely a vertical issue. You can get the deflection board for that model from www.tvcircuitboads.com
I didn't look up the model to see if its a LCD or LED, if its an LED it sounds like you have some lamps going out, try turning down the backlight settings and see if that helps
The vertical deflection circuit has failed, or has been shut down by a service code entered from the remote control*. Usually you can get out of service mode by turning the set off and on again.
*Normally, you have to enter a special combination of front panel and remote control codes to get into service mode, then enter another code on the remote control to get the horizontal line. The horizontal line is used for adjusting the screen controls for each color so you get proper color in the dark areas of the picture.
five blinks on this unit indicates a weak or out crt tube you can try opening the unit and very gently tapping the bottom of the glass part of the tube to see if you can clear some of the carbon build up from the tube only a temporary fix. be very careful not to break the tube
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.
