LCD Is More Reliable Than CRT Monitor?
As an electronic repairer, the thing that we do not like is the repeated repair. That’s why at the beginning one must do their job good to avoid callback from customers. Callback is a waste of time and quite often you can’t bill again to the same customers otherwise they may want to change to other repair center. Though you have already explained to them that the first fault have nothing to do with the second one, most customers seem like ignoring all this and held you to responsible and wants a free repair. The more callback means the less reliable your service is.
Okay back to the CRT and LCD Monitor Repair. From my observation and experienced, i noticed that the CRT Monitor have more callback than LCD Monitor no matter how fully you have check the CRT Monitor before you send back to your customer. The reason for it is quite simple-more electronic circuits and components in CRT Monitor!
CRT Monitor consists of power supply, color, horizontal, vertical, cpu/eeprom, high voltage/flyback transformer, degausssing circuit, s-correction, yoke coils and picture tube! While LCD Monitor only consists of power supply, inverter board, Mainboard, backlights, controller board and lcd panel! CRT Monitors circuit board have lots of dry joints problem compare to LCD and the advantage of LCD Monitor is that all of the board are quite small and have less components in it.
