Hi Chami,

It depends on what is the problem with the mcu board. If the programs in mcu run you need a new program together with a programmer to program it or you find an ic that have the original programs but usually very difficult to find it.

Hi Chami,

If the line is permanent it can't be repaired. You have to replace the whole lcd panel.

Hi JOJO,

First you need to make sure the output from the power supply are good and stable. Next you need to make sure the output from the voltage regulator ICs in the main board are good too such as 2.5 v or 3.3 volt. If the voltage is good then chances is high the MCU chip in the main board have problem.

                  I need your advise about the HANNS.G lcd monitor that i had repair for several days now and still couldn't find the culprit.The symptoms is when powering on the monitor,the power led light but there's no display on the screen for about 2-3 seconds then sudden shotdown and on automatically on its own.I had check the standby 5volts found unstable maybe because of the "on n' off" status of the unit but when i disconnected the connector from main board,the standby 5volt is stable.I suspected the main was the problem..Am i right about my analysis that  the main board is the problem on this monitor?What is the possible device or chip that causing the problem occur?pls. give some ideas if the problem is really the main,what should i do to isolate the problem in the mainboard..
thanks,
