Is NEC E552 a monitor or TV? IR reciever?

[Mattmoosh2000]

I'm about to dive into the troubleshooting guides and think the E552 is a TV, but i am not sure. It's a Display Screen.

Got it for $100 I put a new/used main board in it. Speakers weren't working, but headphones were.

Rebooted it and the inputs are locked.

Got a universal remote to try to enter 0000 in parental controls, but the brand new universal remote cant find the code. Tried entering them all in manually.

Thinking it may be the IR reciever... is This tv IR? i heard some remotes are RF?


Thanks for your time!

Looks like it's both, a display screen with built in tuners: https://www.necdisplay.com/p/e552

Some remotes won't work with some tvs, do you have another universal you can try with it?

i have tried it with a verizon remote and a GE universal remote from amazon. both with new batteries.

took a video of the remotes having buttons pushed, to see if the IR LED was coming on. they were.

tried searching for the code with the setup functions

Can you get access using your PC/laptop via RS232

[Mattmoosh2000]

Re: Is NEC E552 a monitor or TV? IR reciever?

ok. i'll try the RS232

I have been guessing that input would be blocked aswell.


does the TV support a USB Keyboard?

Re: Is NEC E552 a monitor or TV? IR reciever?

It is Locked. It seems all of the inputs are locked. It has a password sign that flashes when ever i try to do anything

There is a USB input that supports Mp3 and such. It has a more automated interface, but the buttons on the TV don't control it.

To un-lock the OSD press and hold the MENU button while the monitor is off and then press power button to turn the monitor on.

[Mattmoosh2000]

Re: Is NEC E552 a monitor or TV? IR reciever?

What is OSD?

I tried that, nothing... just "password"and a yellow bar, and "input locked!" jumping around a blue screen.

is there a firmware update i wonder .

[nomoresonys]

Re: Is NEC E552 a monitor or TV? IR reciever?

OSD is on screen display, it looks like you either need that password or a way around or way to reset the password, thinking there must be a way to do it, for just such cases like this where it's not available or forgotten/lost.

Did you try contacting NEC? seems like they should have a solution if it's just password locked out.

the default password for locked paternal or channel are 0000
you can use USB keyboard ps2 or air mouse keyboards too

I should have known they would be closed on a Saturday.

No one thinks it is the IR receiver off the bat?

Maybe these universal remotes aren't compatible?

Is there a particular Remote that i should try?


There is a special user interface with the USB function, i believe one can use a keyboard and mouse in that function, but not for tv functions?

[nomoresonys]

Re: Is NEC E552 a monitor or TV? IR reciever?

You tried using the button board on the tv to control it?
