Hello,
I originally posted this in the "video issues" forum, but it looks like nobody ever goes there
I've been given a Viewsonic VA2010wb that is apparently dead. Although I get a dim orange light at the power LED, I get no video output at all (no backlight and no OSD, either) and there was a nasty high-pitched whistle which sounded like a capacitor going through its death-throes.
Does anybody know what tends to fail on these TFT power boards? I'm pretty certain that's what's failed, but I can only seem to get a replacement board from the US for $60 plus. I've read on the web that some of these replacement boards have upgraded capacitors, so I replaced three 10V capacitors that seemed to have overheated and domed their end-caps with 25V ones, but I get the same fault, although the whistle has stopped...
The board part number is FSP043-2PI01F - unfortuntely there's nothing else obviously blown on it, so I'm a bit in the dark trying to figure out if it's even this part at fault...
Any help would be much appreciated,
Thanks
