CRT to LCD Conversion for CNC Machines

After years and years of use, CNC machines with a CRT monitor can begin to have defects that appear. In the end, most individuals or businesses working with CRT monitors have outdated technology which will continue to break down or slow down productivity over time.

Tri Star CNC Services, LLC doesn’t want you to waste your money on trying to find a replacement for a monitor that isn’t giving you the results you want. We offer an upgrade service, also known as an LCD monitor retrofit, capable of bringing your CNC machine back into proper working order and the modern age.

FANUC Retrofit Service Saves You Money

Without an upgrade, you will continue to deal with heavy monitors that are splotched with colors and unnecessarily driving up your electric bill. Screen defects that occur over time can keep your CNC operator from being able to control the machine as accurately as they’d like to.

If Tri Star CNC Services, LLC were to perform an LCD Retrofit, your CNC machine’s efficiency will improve. Without spending a lot of money, you get a more reliable screen that makes your operator’s job easier and more productive.
