Out of frustration with the first display (Dell 1908FPc), i decided to crack open another one from the same job lot.
My hope came true - bad caps All C(r)apXon KF, two 1000u/25v and two 220u/25v, all on the +12v for the inverter.
In 10mm diameter, i only had some Panasonic FR 470u/35v, spec'ed at 1.8A ripple (vs. 1.4A for the 1000u) and FR 270u/35v.
I also replaced the CapXon GL 22u/50v for the primary-side PWM, with a 22u/63v Panasonic FC.
End-result - turns on just fine, Acer logo with a fade-out, then shows "No Signal" for about a second, then goes into stand-by (power led goes orange). Sounds to me like it works just fine
(... Because i was too lazy to dig after my VGA cable - it's under my workbench, behind 4 other LCD's on the floor )
I took the picture with the boards after removing the bulged caps - how do ya lile the big ones? Bulging top AND bottom
