I have two monitor identical ones.
The brand on it is dell but the el board clearly prints name benq.
Some numbers of of the units:
CN-0m1609-4663-3ak-54WL(lcd #1)
CN-0m1609-4663-435-36gl (lcd#2)
E172fpb
LCD#1 turn on after 1 seconds goes blank.Show display protection when powered first then a color test on left bottom when repeatetly powered.
LCD#2 turn on it flicks ones and power light blinks .
Where to start to diagnose bad parts.
Boards have no visible damage.Nice monitors.
previous post mentioned transistor(how do i test them)?
Also the caps (what to look for when replacing them size for size and best place to buy them?
Should i replace them all and where to start on that.
Will i work on power supply board (eazy )or on the smaller lcd control board (tiny hard to replace parts)?
Please share your visdom.
