Hey guys,

Got a Hp Designjet T120 that doesn't power on... when the power button is pressed it only turns orange and makes a beeping sound.

mainboard was changed and power supply no change in error message.

Does the display light up? I didn't understand if you replaced the power supply or not ...

Display doesn't light up and yes I replaced power supply also.... i just discovered a flat/flex cable with a missing contact I'll be replacing it today and report back

Hey, no I havent!

I'm thinking both mainboard and power might be shot 😔🤔 I'm thinking I should have replaced both at the same time and not one at a time!

But I'm still trying to figure it out.
