The part which could have gone faulty is
+5 volts line is overloaded (A,B boards)
+5 volts line is shorted (A,B boards)
IC6007 is faulty on A board.

Unfortunately, just about any problems on the low B+ lines will generate this error. I've run into several situations where the tech has replaced all of the boards and the problem remains.
It is usually one of the deflection yokes and if not that, one of the video drivers
on the C boards. Unplug the yokes (CN017, CN018 and CN019 are the numbers I believe though they may be different) one at a time while turning the set back on to isolate the defective yoke.
NOTE: Disconnect the C boards from the tubes to avoid phosphor damage.
Let me know how this turns out.

    You need to diagnose it more, I told you to start by unplugging the yokes, if you have no electrical expertise, I suggest finding someone who does so that they can do this. This is a dangerous and expensive tv to be working on and the error code will not specifically say which part but will give a general area where you can find the problematic part.

Tv does not come on and the power light flashes 6 times


I'm not entirely sure what that means, but this website says: 6 times, Diagnosis: LOW B OCP/OVP (Overcurrent/over voltage). Possible causes: +5 line is overloaded. (A, B boards), +5 line is shorted. (A, B boards). Symptoms of the problem: No picture.
It sounds like it will need warranty work. You can always try unplugging it and waiting 5 minutes and plugging it back in.
Please don't rank me low, I'm not an expert here, just trying to be as helpful as I can.

Will only turn on for about 3 second with no picture and then turns off. Standby light blinks 6 times


For the KV30HS420, 6 blinks, pause, 6 blinks, etc. means "LOW +B OCP/OVP (overcurrent/overvoltage)" and the probable cause locations listed are as follows:

1. +5 line is overloaded (A, B, M boards)
2. +5 line is shorted (A, B, M boards)
3. IC504 is faulty (A board)


hope this helps John

6 times, Diagnosis: LOW B OCP/OVP (Overcurrent/over voltage). Possible causes: +5 line is overloaded. (A, B boards), +5 line is shorted. (A, B boards). Symptoms of the problem: No picture.


replace the two mcz3001 ic's on the d or dz board, this is a common problem they have used this circuit for years, so the exact board number may be diffrent, but it will be located on the board with the flyback.

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.
