Much better to describe the fault instead of what you think is what needs fixing.

the fault is that it always show me no single, cable changed, PC changed, made sure the socket connector is fine
what else to check to fix that error

Have you traced all the cabling to the board for any breaks..?

The FBI must feel like this when trying to get information from a suspect!.

In the mean time, does it have any indication of power?, back light?LED?, noise?.

Have you checked the fuses on the board and in the plug (if it has one)?.

Hello,

Does the monitor have more inputs?
It seems to have the following inputs : Composite, DVI-I, S-Video, VGA (D-Sub).
Then try an other input and see if that is working.

the screen turn on and show on the screen that Error message then go to sleep mode

tow on the power circuit and they are fine

It seems to have power or at least standby power.
I would check all inter-connect cables to both boards. Unplug and reseat. Check for cracked or dry solder joints. Check those cables for continuity too.
Your photos are too fuzzy to enlarge.
Can you see a connector that may have voltages written on the silk screen?. If so, check those voltages.

On the PCB, there are reference designators. R32, C14, F2 etc. Not necessarily the numbers I wrote.
Any lettering, numbering or symbols are silk screeen printed onto the PCB.
You might have a connector with eg: 5V+, 12V+, 28V+, 0V.
They are voltages on those connections and therefore those rails.

1. How old is this unit?

2. Have you had it from new?

3. When did it start exhibiting this fault?

4. Did the fault suddenly appear, or did you have increasing difficulty with the monitor before it finally failed?

I have seen similar problems caused by power supply issues in monitors. However these faults often develop over time. They are also faults that tend to occur in older equipment, or equipment that has been continuously powered on for years.

I would be checking the ESR of the capacitors in the power supply. I've taken a look at your photos and none of the capacitors look stereotypically faulty.
