I have Siemens HMI MP 277 10 inch 6AV6 643-OCD01-1AX1
When I power up it first brightness on screen then at left side green color bars appear and finally it becomes blackish some one help me what is problem of it.
Screen is defective.
MP277 is discontinued, which means that a replacement MP277 will be very expensive.
Send the MP277 to Siemens for repair.
Or migrate to a Comfort Panel, or a PC RT.
