HP Envy 7858 has blue screen with error message 000829C98

[Sue92318]

My HP Envy Photo 7858 printer has a blue screen with message 000829C98 on it, it also has multiple lights flashing on it, and doesn’t respond to anything on the touch screen.  I saw this issue on a previous post & followed the instructions  to turn on printer, remove ink cartridges, unplug power cord from back & wall, wait 60sec, plug back in, turn on....I got the same blue screen with same message & flashing lights.  

Now what?

Welcome to HP Forums. This is a great place to get support, find answers and tips.

I have gone through your Post and I would like to help 

Let's start with a Printer Reset once again

(1) Turn the printer on, if it is not already on.
(2) Wait until the printer is idle and silent before you continue.
(3) With the printer turned on, disconnect the power cord from the rear of the printer.
(4) Unplug the power cord from the wall outlet.
(5) Wait at least 60 seconds.
(6) Plug the power cord back into the wall outlet.
 NOTE: HP recommends connecting the printer power cord directly to the wall outlet.
(7) Reconnect the power cord to the rear of the printer.
(8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.
Wait until the warm-up period finishes and your printer is idle and silent before you proceed

Then update the Firmware from this Link: https://support.hp.com/us-en/drivers/selfservice/hp-envy-photo-7800-all-in-one-printer-series/907315...

Keep me posted how it goes

I tried everything that was suggested.  In the end HP sent me a replacement under my warranty.  Thanks for all the help.
