you are right it blown 2 mosfets too,,, you are master Thank
I ready order 10 for 2$

"R6603 on D1N is shorted too,," That is confusing DATA when you indicate that low ohm resistor is shorted. If that fusible for the 395V is blown then you have bigger problem, you need to check the resistance between Source and Drain pin of those MOSFETs to make sure they do not show low Ohm resistance.

Re: sony kdl-46w5100 no red light standby, on green off red light flash 14 times

It is only 0.46 Ohm, it is not shorted ((used ohm tesed is no reading)). that is normal.
I am looking for the RESISTANCE reading of the original 15V zener(( used diode mode tested both side is 000.0)) that you removed and and the resistance reading between the two pads on the board where that 15V Zener was. RESISTANCE, nothing else.
Why are you checking R6603???
1) Do not use continuity mode for testing for shorted circuit, use Ohm meter and report the resistance reading in both directions.
2) I am beginning to believe that that the 51V zener is OK and the IC may be still OK but I cannot tell until you provide the RESISTANCE READINGS as requested. R6636 for that 12V power supply line would have blown open circuit by now if the IC and the Zener were shorted out.

I know the R6636 is blown used ohm mode tested it show not thing
used diode mode tested zener diode for both side it show 00.0
used continuity checked C6615 has sound

"What was the resistance of the that shorted 15V Zener that you first found in the beginning? ,, it read one side is 0.152 the other side OL"
That does not indicate as shorted because one way it shows 'OL'. ( NOW BOTH SIDE has continuity 000.0

So what is the RESISTANCE reading between VCC and GND(VCC and GND which board? powersupply or D1N ), I need that data?( I alreay removed IC, zener diode and the rectify out of circuit D1N
The fusible should have blown too if it has shorted circuit that is why the fusible is in place.

Yes you are right !! R6603 on D1N is shorted too,,

Re: sony kdl-46w5100 no red light standby, on green off red light flash 14 times

But what are the resistance reading of the original 15V Zener that you found it is bad?
I need reading in Ohm.

Re: sony kdl-46w5100 no red light standby, on green off red light flash 14 times

When you indicated the component is shorted, what is the RESISTANCE reading in both direction? yes it read with continuity both side
What was the resistance of the that shorted 15V Zener that you first found in the beginning? ,, it read one side is 0.152 the other side VL

order IC and rectify diode, and zener diode, i will update my tv soon when i have all components
Thank Bubm

Re: sony kdl-46w5100 no red light standby, on green off red light flash 14 times

Today i do test two led of zener diode i make accident touch the other test lead to somewhere i don't it sparked then i check around the D1N is shorted oh my god finally i found out it shorted the diode D6612 I removed it out but the circuit still shorted then checked the IC6601 too many pins with continuity then removed out then everything no more shorted so i order on ebay and waiting ,, during this time to check t-con for experiment i will be back and report here soon Thank Budm

Re: sony kdl-46w5100 no red light standby, on green off red light flash 14 times

See my post #53, you need to locate and test bunch of Voltage test points per some example that I can see from the pictures, there are many more on that T-CON board.

Re: sony kdl-46w5100 no red light standby, on green off red light flash 14 times

BTW, can I see good clear straight shot pictures of the T-CON board?
I still think you have problem with T-CON board after searching about 14-blank code.

Thank Budm sent me the link that man fixed tv the problem is almost the mine
interesting to learn more thing ,,, now i spend time to learn how to test t-con
you have any good idea start to test my t-con ?

I think almost like you but one thing i am not sure that is if I disconnect T-con completely at least when I turn on the tv I have to see backlight light up but otherwise, I see a just black screen
give me idea Budm, i will take more time to test then will make a decision
----
one more thing is how to check volt at HV from D1N board?
Thx

Re: sony kdl-46w5100 no red light standby, on green off red light flash 14 times

Those two parts have white body, correct? They are capacitors not resistor.

how come they has lable R that is why i think resistor
will know

Yes it is white Thx

Re: sony kdl-46w5100 no red light standby, on green off red light flash 14 times

If you look at the T-CON board both sides you will see many Voltage test points, I.E

Re: sony kdl-46w5100 no red light standby, on green off red light flash 14 times

I upload the t-con boad i suspect 2 resitor on the top and the bottom the same position from it
R16 and R315
tested with ohm metre 4k,40k,400k,40M,4000M and continuity but no sound no reading any number just OL
you think the resistor on t-con board shorted?
