hi , please help me that when i shutdown the power of my machine TONGIL 10M it goes to ipl mode every time, how to solve this problem

[guhl]

what happens when you push "6 - end IPL"?
are there parameters in CNC still?

[sajidali]

when push 6 then ok, but after some time when power off and again on then again show ipl mode

[guhl]

in this case I would reburn eproms with firmware

The issue is unlikely to be in the eproms.
First: check the powersupply voltages on the motherboard..
Is anything flashing on the IPL screen?

agree
voltage problems occasionally cause strange results
may be swap power supply with another master board?
if there is no one available, check power supply using oscilloscop, in this way you will see "quality" of voltage
