The most likely cause is a broken red signal wire in the monitor cable. The next possibility is a bad connection at one end of the cable going to the CRT board inside the monitor. It could also be a thermal-fatigued solder connection in the red cathode driver circuit on the CRT board (this can often be found by visual inspection after removing the CRT board shield).

If you don't find one of those three problems, you'll need to use an oscilloscope to trace the signal from the input cable up to the red cathode terminal. (Caution - high voltage here!)

problem with the monitor Display cable. it is damaged.

Normally monitor will receive 3 colors red, green, Blue signals from CPU. If one cable i.e Red wire connection is missing in display cable which is connected to monitor, Red color image on monitor wil be replaced with other fade color.
So, need the replace the display cable or display connector!

check the connection to the cpu.fix the VGA cable connector.

data cable connection may be loose tighten the same
replace the data cable

The unit is saying goodbye, in it's special way. There are very limited repairs for CRT's nowadays. A good cheap flatscreen is always available. Trust my word on the CRT's. Sorry. Thank you, Dana

LG 700E monitor's power LED blinking continueously and there is no display solutin ........

do both until satisfied.

If the problem varies with temperature (on time), then you may have a failing flyback.
