LG Monitor problem... Closed

Question

Hello, 

The LG monitor which I am using goes on restarting again again by itself after using the system for some time... Processing of the CPU is ok and all the tasks I do are working prorerly but the screen goes on getting On and Off again again whithin the fraction of 2-3 seconds...

After restarting the whole system it again works properly for 1/2 an hour and starts giving trouble in the same manner....

Please help me out.....

Hi,
    Assuming it loops on/off by itself when switch on....
I am aware of two possible answers one is that the power transistors are over heating , or two the MCU of the vga has become corrupted. 
If the looping cycle of on/off is from the moment you switch on the w2234s
then it's the MCU. These replacements are sold on ...

  If the looping on/off is 5 to 30+mins or longer then its the power transistors.
Your can have a temp fix of added addition cooling , open the case at the bottom
() and put a fan to cool underneath @. If this works then to find the cause of the over heating and repair or buy another w2234s inverter/power board, usa $50, china $15.  If the looping has got worst i.e. less time between looping then will
fail completely at some point.
