20 Most Recent ViewSonic E70f 17" CRT Monitor Questions & Answers

It's time to responsibly recycle your old CRT monitor, and spend about $100 to buy a new 17" or 19" LCD screen, rather than spending any money at a qualified TV/video technician, trying to trouble-shoot the problem.

You are having a problem with the OSD lock on your ViewSonic Monitor. Is that correct?
If so, please follow these instructions to unlock or lock your monitor.
On some display devices, there is an OSD Lock that locks all current control settings and prevents access to the control menus until this mode is unlocked.
The method for unlocking the OSD is different for different monitors, but will be one of the 2 below. If the first method doesn't work, try the second.
Method 1: Press and hold both the [1] button on the front of the monitor and the down arrow button for 10 seconds.
Method 2: Press and hold both the [1] button on the front of the monitor and the up arrow button for 10 seconds.
Note: These same buttons, when pressed for another 10 seconds, will lock the OSD

Please let us know if you require any further help with this matter.

It's much better to just replace it.

Soldering usually. Some connnectors were prefabricated with rubber being injection moulded. Your best bet is to purchase a 15 pin D connector and change the old one by soldering.
