Why will printer not turn on?

Power of correct voltage is being provided at printer power input terminal. Printer on/off button has no effect. Printer appears "dead". HP Customer Service FAQ not helpful for this problem.

What would be the chance of getting that Officejet Family Technical Support Solutions Guide back up on Keepandshare.com? It's no longer there and I'd love to see if it has an answer for why my Officejet 7410 won't complete a start up sequence but only cycles the LCD screen over and over.

You more than likely have a faulty wireless card in your 7410. However, the good news is the rest of the printer is probably still fully functional. I did a little google work and found a link to an article that shows you how to disconnect the built in wireless card to test.

Good luck!

Thank you SOOOO much for that link. I disconnected the wireless board as instructed and presto-chango, the printer booted up normally. I tried, as one person suggested at that link, to reconnect the wireless board after a successful reboot with it disconnected to see if it worked. But in my case, the reconnected wireless board would not allow the unit to boot. So, the wireless remains disconnected forever and I don't care. Don't use that function anyway. Printer is up and running normally. Thank you, again!

Glad to know it worked for you, Jack! The reconnection suggestion that you reference from the article is a misnomer - The problem is that if the card is bad, it just won't work - period. Some users have found that AFTER booting the 7410 with the card unplugged - they can reconnect it without crashing the printer - as long as the reconnection is done with the power ON. But wireless capability will NOT be restored. Plus as an undesirable bonus, the next time the power is removed and then reinstated, you're right back to the looped boot fail! The only way to confidently repair this is to replace the main logic board AND the wireless card - which is, in my opinion, far too expensive of an option for a printer of this age. Good luck to all! - Randy

Most probably these models comes with an external power supply. So all you need to do is to try changing the power chord first and if you have a volt-meter then do check if the supply is giving the prescribed voltage or not. If not then replace the power supply.

Yes I did all these step but it doesn't direct any effect above the printer. Now its logic board is demage (means back side of main board i remove one part like 8 pin MOSFET from there) so I decided to replace by other formatted logic board buy from eBay. Thank you sir for giving me your precious information, Thank you so much.
