LEXMARK X656DE blank screen and beeping

[blanka]

Hi

I have a Lexmark X656DE that when you switch on the screen will stay blank/black and it will beep 3 times then stop then beep 3 times again then stop and it will continue the sequence of beeping, if you tap the screen or press any button then the screen will lit up abit (change from black screen to gray) i cannot hear any motors running, see any lights flashing or even hear the machine trying to boot up at all.

Any help would be appreciated

You might try swapping the touchscreen assembly, I had something similar to this a while back and that was the final resolution to the problem that time. Then again. I could lay the back of my hand on the display area before the problem was resolved and feel unusual warmth even though the display appeared to be off, so if you haven't seen that take this with a grain of salt.

My suggestion is to try and replace the LVPS and if that doesn’t work I’m afraid you will have to replace the sys board or the op panel.
please notice that both this parts has NVRAM on them so they must be new. if you want to replace them from some other printer you will have to replace both at the same time or NVRAM mismatch will apear.
