My wife has an NEC 46" Accusync display that's being used for digital signage at her venue.
The monitor started to act up 3 months off warranty (need to check which CC I used... may have put it on the AMEX which *may* have extended the warranty.
With that said... I thought I'd try and see if someone here would have a suggestion. The symptoms:
- The remote control can power on the monitor. Once on, the remote does not work and the picture is blank. Note: The same remote does work with another NEC monitor that is not exhibiting these issues
- They called NEC and they suggested a hard reset (unplug the monitor and keep it unplugged for 30s)
- When the monitor powers on, a series of white blocks will pop up randomly on the screen. The rate at which the white blocks appear on the screen decrease until at some point a red line forms across the screen. The red line then remains on the screen.
- Repeating the hard reset process results in the same behavior.
Not sure what to try... NEC suggested taking it to a local authorized repair place that wants $125 to diagnose the issue. They'll refund the $$$ if they fix the problem. I would suspect the "fix" would mean replacing one of the internal boards which would mean big $$$. At least big enough where it would likely cost about the same to buy a new one.
I did mention for them to try the other inputs... Although, when there is nothing connected, the same white block sequence starts (It's possible they didn't manually change the input though).
