Sony KP-46WT520 Picture yes and no

When turned on there's sound but no picture within 10 seconds or so it shutdown and standby blinks 10times.

If left off awhile and turned on 1st time you might get picture if not then few time on and off get it.

If left unplugged for awhile then turn it on you get picture on first try.

Either way when you have picture and turn it off you wont get picture till it sits off or unplugged.

I know the parts you should change with the 10blink code that's service manual say, But if i can still get picture they might be working or they might be having Intermittent problems.

HV Protection 10 times 10:0 or 10:1
• Q8014 or Q8013 have shorted replace along with R8051 on D Board
• IC8005 is damaged (D Board)
• No picture
Q8014/Q8013 TRANSISTOR 2SK3568 No idea how to test with DMM
R8051 FUSIBLE 0.1 10% 1/2W Check and was in tolerance range
IC8005 IC TL1431CZ-AP No idea how to test with DMM

So what do any of you's think.. Thanks for any info

As of now the TV picture only

As of now the TV picture only comes on once you turned on and off 2-3 times.

I replaced IC8002(MCZ3001DB) and IC6400(MCZ3001DB).
