Top View Of Monitor Mainboard Troubleshooting

Most of the time when we troubleshoot monitors we seldom look at the front side (view) of the main board. We will just take the meter or solder gun and begin troubleshooting and tracing the bad components at the back of the main board. Do you know that some monitor problems can only be solve by looking at the front side compare to the circuitry side. Why? Because you can observe any leaked in electrolytic capacitor, a burnt resistor, a cracked transistor, a loose wire or connector, a bulge capacitor and so forth. I still can remember there's one acer monitor which have a weird problem and i could not solve it. The problem is intermittent (sometimes have power and sometimes power blink) but when i look at the front side of the monitor mainboard and power on the monitor i saw a small blue light at the secondary side of the power supply. Close inspection found one of the resistor leg is touching the secondary diode. Both components is located just under the belly of the crt tube. If not because of the blue spark and looking at the mainboard from top and side view i would not have successfully troubleshoot the monitor. I suggest that if possible take out the whole board and see if you can find any trace of problems by looking at the board front side and of course it depends on the complaint or the problems of the monitor.
