Repair Locked SAMSUNG Monitor

Immediately, I share here will be how to repair / Service Monitor SAMSUNG, damage to the monitor itself is the emergence of the display control lock / locked at the time the monitor is turned on.

Likewise, when the VGA cable from the monitor connected to the PC nothing happened what / no response: (. After the check was coming out of the IC voltage regulator 7805 experiencing leakage to the measured voltage of 7 volts. For more details please see the picture:

Check the location of the regulator IC 7805 to IC MICOM

Measure the output voltage regulator IC

When measured more than 5 volts, replace / replace IC 7805.

Regulator IC 7805

A good idea to check also the conditions that are beyond the range of IC / after the IC is revoked, is to ensure that the voltage over 7 volts which causes the samsung monitor is not damaged from the other components of the Monitor. We can use a simple circuit to check:

 

Input leg is leg number 1 from the left when we look at IC from the front, ground is the foot of No. 2, while the output is the foot of No. 3.
Unfortunately I do not have a schematic of this monitor so it can not show directly where the exact location of this IC on the circuit, but I think with the instructions above picture can be quite clearly not
