Toshiba Tecra A11 - Orange Blink and No Power

[nrcslim89]

Hello all once again, today I'm presenting the follow issue on a Toshiba Tecra A11.
I will post more motherboard and detailed info later.

So basically the board won't power up.
If you try to power it on switch there's no response.

The only thing you can see is on DC In LED, blinking orange.
With 3 long blinks wait for a second... and 2 short blinks after that it loops this sequence.
I search over Google, and seems theres a method to identify this issue by converting binary to hexadecimal and we get the error code of where's the problem on circuit.

I try some 3 different binary codes and I get different codes... Because I don't know if I have to start with 0 or 1 the sequence.

Anyone here know how to solve this blink code to hexadecimal?
Starts with 3 long orange blinks
Wait a second
Show 2 short orange blinks
And start again the sequence in loop.

Ok, motherboard info is this
A5A002688010
FHNSY1
Tecra A11

And i am sorry but the blink code are the follow
2 Short
1 Long
Stop 1sec
1 Short
1 Long
Stop 1 Sec
3 Short.

So in my logic this in binary goes like this
00101000

I try to convert it to Hex or Dec online and i have this two
Hex: 28
Dec: 40

I check one online page and theres no 28 code.
But... i have the 40 Dec

S5V output
Error code Meaning
40h S3V voltage is under or equal to 3.14V.

Coukld be this the problem ?
I have the schematic of this board
Anyone want help solving this ?

Hello everyone, today i was again trying to fix this issue on this board, i checked and until now for sure i have the 14h (HEX Code) wich means "Current sensing IC is not normal."

So at this point i was trying to check some components and search for a possible short to GND with PSU using the 15V - 5A.

I have the schematic of this board and i want your help please to point me for some ICs or values i should search.
My PSU, is stable on Voltage, but AMP and WATT are very unstable each second,
Amp goes between 0.049 ~ 0.050
