I have a princeton monitor, and it is starting to zoom in and out by itself, the brightness also changes. What the heck is going on, how can I fix it? I don’t know whats causing it. Thanks in advance.

how old is it?

is it under warranty?

do you have it on a surge protector?

Sounds like the control board is faulty. I had one that had manual adjustments for rgb, took it in and it was going to cost more to replace the printed circuit board than to buy a new monitor. Their all throwaways these days.

Shouldn’t matter, as rev said, check your warranty first, you should have had at least 12 months.

the lack of a surge protector could be the source, but only if a surge came thru the line and messed up the control board…

but as David said, it sounds like a control board prob.

take it back…

or buy a new one…
