Accuvision 42" flat panel moniters

[tstaud]

I have a monitor that will come on. What I mean by that lane 7 will turn on and the grid will come up but lane 8 will not. I am running Accuscore Plus with 7500 cwc. I reset the cwc. I can power the monitor on but can't do anything with it. I can't change it to the tv. I can't change channels, etc. When I try the push the input button or any other button on the remote the power light flashes red and green. Any ideas?

More information....I can turn the lane in league format the grid comes up on lane 7 and you can put your names on lane 7 and it is your turn to bowl on lane 8 it will score. So I am thinking a monitor problem. Is there a way to reset the monitor?

[tstaud]

One other thing.....I put the lane in stand alone.....7 comes on but 8 still does not.

Did you try unplugging the monitors/tv's for a few minutes to try to reset them? That should theoretically work to reset the tv itself, since it sounds like the tv's the problem since you can't even get the input screen up on it.
Another thought that occured to me, is the remote you use for the tv/monitor just for that, a television, or is it a universal remote, where it can control a few different devices, such as dvd players, etc. If it's a universal remote, then I'd also make sure that the tv function is selected. I only say that because some of the universals will switch power on but to control certain functions as changing channels or inputs, you have to specify the device you want to control. (I have an aunt who has one and end up reselecting the tv all the time for her because she's accidently bumped another device key).
I have LCD's as well. My setup has a convertor box on it that takes the signal from the ribbon cable and sends it to each monitor thru an HDMI cable. It also has an LED on it for each lane, it's either red for off or green for on. That helps me determine if it's a problem at the monitor or from the CWC.
Once in a while when I'm rebooting my CWC's, I'll have to do a cold start and hold the cold start/reset button on the chassis for about 10 seconds because it won't send a screen to one of the monitors in a pair.

If this is the actual Accuvision from QA,where the monitor plugs into the power strip the is a small plug that the monitor plugs into for power control then into the power strip. Try removing the power control and plug the monitor directly into the strip and you should gain control of the monitor,off and on. If it does not power up with the remote then...perhaps you have lost the monitor.

I have had the input mysteriously get switched to the wrong one before so something to check.

What happens if you swap signal cables between monitors?

What happens if you swap signal cables between monitors?

This was the first thing that came to mind. It will tell you which side of the LQi the issue is on. Since it's plugged in with a ribbon cable, you cannot test the LQi output without swappng it out with another overhead. Just swap the VGA output on the left side of the LQi.
If if the issue moves to the other monitor, swapping the CWC will tell you if it's the LQi or CWC.
But, also check the LQi where the ribbon plugs in. Doubtful, but an easy one to eliminate.

Okay Thanks for the suggestions. They are the actual accuvision from QA. I have plugged this monitor into a not connected with the conversion box or power strip. Something that I did not notice before that has been happen this whole time was when we turn the monitors on the lane 7 the AMF logo comes up on it and on Lane 8 it does not. The other thing I am noticing is after I have the monitor on after about 15 minutes it powers off by itself. So, part of me is leaning towards power supply. Does anyone know if I can just use a LCD TV instead of the monitor. I will also work on the other suggestions too.

Ted,

The only ribbon cable I have is from my cwc to the monitor control board. My LQI has a power cable from the board, 2 rgb in cables from the board, and blue-green-red component cables out to the tv. I have a monitor control box that has a one vga type looking plug that splits and goes to a vga type looking plug going into the monitor. So, I did try to swap the rgb cables and had no luck. 7 still worked and 8 did not..I also put up a know good spare cwc and still no luck.

Then it's the monitor. You can try the coax input to see if you can still use it as a TV, but looks like it's time for a replacement monitor. Warranty? Won't hurt to ask the salesman. Many brands of commercial grade have 3 years.

Are you sure it's not a CWC causing this? It happens - I see CWC's that have this problem on occasion.

A very common issue with these monitors is power supply failure. It is not hard to change them out so you could swap power supply's between two monitors to verify. Since I do not know what version of monitor you have, you would be better to call QAMF to get the proper part number for the power supply you will need. (Yes...there are multiple versions of that same monitor)

I did swap this power supply into a different monitor and same issue. Put the good one in this monitor and it worked. So I will contact them and get a new power supply. I have 1st generation monitor.

Thanks for everyone's help,

To get past the hump until your part shows up you can have the good monitor in the left lane and use the pair in league tv mode.
That will put both scores on one lane,the left lane until you are fixed. You can also put up a different monitor as long as it has the same input that the LQI wire is putting out,mine is the computer output style cable. Just plug in directly into the power strip for electric and use the remote for off and on.
