LCD video fails after several seconds, but power / signal connected led-remains green or sometimes can also flash or show standby yellow.
This model check Q791 fet for shorted drain source pins 2n7000 type I replaced them with ebay purchased fets of to92 case type.
Replace bulged electrolytic capacitors with high temp 107c LOW ESR capacitors 1000/25 470/35 etc any lcd has these.
I have had 2 e173/176 monitors fail and both were repaired after caps replaced. one with fet and fuse replacement.
c5707 transistors check for shorted leads be bc ce check HFE gain if Multimeter capable replace with kit.
Include 3a pf751 fuse in test if open cct replace.
remove and check q743, q751 fu9024n fet replace if shorted leads apparent.test with fet tester /multimeter or download and build simple fet test cct.
