The monitor is DEAD! All the components inside seems to be OK! I checked them with multimeter, I have some knowledge with electronics, but not enough to deal with this kind of problem, and with no schematics, no spec. equipment and so.
Monitor makes NO sounds whatsoever, when I turn the POWER ON, no HighVoltage!
Everything I checked is Ok.
I need help! From where to begin??
Thanks in advance!

Hi, R105 is OK.
I've checked every single component on the board and is OK. except all IC's because I don't know how, also I checked on shortcut all the transformer except on Flyback.
I did the checking without power because I am not shure how should I do that with the power on, but what I checked is AC line around AC inline, and that should be OK.
What I do not understand is why I have no LED on, and no NOTHING when I turn the power on, but I have 220V at the AC inlet??? Until now I did some monitor repairs, and I know things about electronic, but everything was logical to repair, I had LED's on, or some sound inside, or anything to go on, but this one is DEAD! And everything on board seems to be OK!
H E L P!
If I menage to repair this problem with your help, this would be one fantastic school lesson for me!!!
Thank you!

Hi,
I measured the voltage:
At c105 - 314,3VDC
at pin 7 of U101 (TEA2262) 0,05VDC
After some time, when the monitor is off, I turn it on again, and in moment I heard HV (or was that degaussing?) but that was in one microsecond!!!
By the way, I have no schematics of this monitor, I have some other monitor schematics similar to this one, so I use this to understand the logic, like ACER.
Thank you!

I have monitor EIZO FlexScan F55S and it works fine!
I have another EIZO FlexScan F56 with broken FBT, and I have very much trouble finding FBT on the market, so I'm wondering (I don't have data on those monitors) can I use FBT from F55S on F56 ??? Because the F55S have schraches on display and the F56 is in wonderfull shape!
Thanks!

Thanks for schematic! My model is a bit diferent, but the schematic is helpful.
I measured all the voltages, and I have all of them just the way they should be!!!!!! and the monitor is still DEAD!!! Am I crazy or what? What is going wrong? I'll throw this one in garbage!
Thank you! Bye!
