So, here is another problem got on my laser machine...

In the middle of a cutting job, i looked at the machine lcd, to see job time... screen frozen... ok, i said... let the job finish, then, reboot the cutter... happend once or twice... after 20 minutes i did that... machine rebooted ok, but the controler LCD all white... weird, but wtf... it's made in china, so ****s happens... power off, wait 10 minutes, and power on again... and still in the same condition...

The laser works ok, but the LCD is all white... no image, no nothing... just a white light... the buttons are working, the laser is working, but no image on the "wonderfull" full color lcd...
The controler is a RUIDA RDC6442, on a laser engraver used about 300hours in 10 months... 3rd bad problem i get since i bought it...

Question is: i can change just the front panel? or i can find a better controler even if it's more expensive?
do i have other better alternatives for controllers than ruida ?

the rouida controler is mounted in a 1200x900 laser engraver with a 80w RECI tube...

Thanks in advance for any construcive advices
