I have a Viewsonic VX715
The issue with this particular unit is that the picture goes blank few seconds after it is turned on.
If you turn the lcd off, on, off, on, off, on, off, on. Or change a resolution a few times it eventually starts to work and works properly untill turned off for a certain amount of time.
There is not much inside the lcd, only the power board and a signal input board, for a lack of a better name at this moment.
The backlight is perfectly fine, picture and backlight are both not operative untill turned on and off a few times.
Do I suspect correctly that the powerboard would be the issue in this case, its a single layer board it would not be too difficult to replace any of the components on the powersupply board if required
both inputs have the same issue, does not appear to be a input issue.
picture / backlight come on and work perfectly for around 2-5 seconds at first, after which the display goes completely blank but power light remains green.
resolution can be changed and the picture will return for a moment with good backlight as well, after a certain amount of on, off, on, off or resolution switching the display operates perfectly for unlimited amount of time untill turned off again after which - being cooled down the on off routine has to be repeated.
I've had the display apart a few times now and I can not find anything wrong with the boards.
maybe someone with more experience can help me as to what to look for or what components I might have to obtain and replace from the powerboard to get this to work like new again.

Printer indicates "printing" and receiveing "data" but nothing prints and I cant get the printer to reset. I turned the printer off, unplugged it and let it sit. I removed the ram hoping that on reseating it would clear itself but nothing has worked. Printer has been down for 2 days
