I have a LUMENIS Lightsheer ET and I´ve got the following problem:
The equipment turns on normaly and starts the radiation emission as well, but some time after using it the display starts to fail turning off the equipment screen, but the equipment continually work, but it could not seen the parameter on the screen and for security tasks i´m not working it.
If turn off the equipment and wait for some time and turns it on the equipment starts work but the same fails occur like describe above.
