Hi Forumers
I have a ViewSonic VA712B Monitor that it powers but as soon as it receives a signal the led goes green but i only see a flicker and goes black. By turning it off and on it works but with whine sound that its been like that for a year now. If I turn off the monitor the whine still there. Got a new monitor, but want to fix this one for my kid new old computer.
What i have done so far - Open the back case to find very little regular capacitors, most are surface mounted and the PCB looks very clean for the age this have. Check connections and solder joints
I posted a video of the whine it makes just hope YouTube don't mess with the already crappy audio. VA712 Inverter
Btw I cannot find anything related to the inverter transformers they have a number SIT36350-1736 G534T
