I have a Sony projection TV KP-46WT510, when the set is turned on the
standby light blinks four times. I have replaced IC8003(LA78045). (the
board number is A1302708A)
After replacing the IC I am still experiencing the same problem as the
standby light is still blinking four times. I am asking if you can
assist me with the problem and a service manual will be greatly
appreciated. thanks in advance."

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.
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.
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.
