Deskjet T120 power issue

HP Recommended
HP Deskjet T120
Microsoft Windows 7 (64-bit)

Unplugged printer during a thunderstorm, and when I plugged it back in, it does not boot-up. There is a blue line across the bottom of the display screen, but nothing else. It did this before last week, so I wiggled the power cord at the rear of the printer, and it powered up, but it will not do so now.

At first try to follow the below steps and get it fix by :

- Connecting the printer to another outlet

- Repacing the power cable

- Replacing the Main PCA (If you have replace Main PCA, it will solved the issue.)

 

Also try to Isolate the printer by removing any connectivity cables, printhead

 

Try removing the ink cartridges, printhead, paper, replacing the power cable and another power outlet. If you still have the problem, please replace the Main PCA (P/N: CQ890-67097)

N.B: Part No. CQ890-67081 is an older revision.

 

Main PCA - T120: P/N: CQ891-67013

Main PCA - T520: CQ890-67023 

 

It is my understanding that the new Main PCA should come with the USB with the FW. Make sure it is there before installing the new main PCA.


If problems with the FW, will not recommend you to use the old USB with the firmware again.

 

If not covered under warranty you may replace Encrypted chip which is failed on the mainboard inside the printer you can buy it on ebay/other's source:

If there no display but inside power up on the Main PCA, you may chage your Main PCA. If totally power will not comes on the Main PCA, please replace Power Suppoly unit (P/N: CQ890-67025).

 

 

 

I hope that answers will support to concern adequately. Let me know! Good luck
