Ok well i have a CMV-1512 monitor and i just striped it and i have herd many things and i wanted to know if i needed to ground my monitor??????? And if so how?
thanks
nick

anyone know???? how i could ground this monitor??

The CMV monitors of the past have not needed to be grounded... only some models of Benq... these things change all the time though... are you having problems that makes you think you need to ground it ? Can you post a picture of your LCD & Control circuitry ?

cheers,

hello
well i havnt even plugged it in yet but i was just going to make sure. This is my monotor.. and the circles are where i took the clips off the metal..
thanks

Hi,
You would probably want to ground just for safety reasons if the ground is already there and available (three prong plug coming off your LCD). If a metal area on your LCD ever got 120VAC on it, and you did not have it grounded, you COULD get blasted.

At least if it is grounded, you will trip the breaker and know that you have a problem.

KidB, yea, this look a lot different than my CMV-520D or the other CMV panels i've seen... If I were you I would try running it as it was, then if I saw problems I would go back and re-trace everything to see if getting the grounds straightened out help fix the problem. I say this as this is what I would do, without really knowing the effects it might have on the circitry. The safest thing to do is probably to tie the grounds together and be sure they all connect back to the circuit boards in the same manner as when they were installed in the monitor before stripping... this means tracing each line and making sure each ciruit board is grounded.

Sorry this isn't much help to you, but I thought I should respond and not leave you hanging. Perhaps there is another member here using the same panel... have you searched the site to see if there is someone else using this same panel ?

cheers,

ok thanks...yeah there are people but they dont talk about grounding...If i tie all the groudns together woutld that mean just soddering them so they are all connected?
thanks

does anyone know what i should do??
thankss

Edit: PM members that have your monitor if you know of any. First hand info is your best bet.

Re-establish all original ground connections and start from there.

You do not want to start slapping in ground wires on every piece of metal on your control circuit board.

When you stripped it you took note of what was connected where. Re-establish those connections and fire it up. You do not have to be very worried about any and all screws that were removed that established connections between the various metallic parts within the monitor. Pay attention to the jumper wires that were there in the first place and maintain those connections. Think about what you're looking at and what happened when you tore it apart and formulate the circuit in your mind as a check on what you're doing. For the most part the grounding issue is not a very big deal but problems can crop up sometimes.

It's a little difficult for me to make out details in your pictures so I can't be more specific.

thanks..all those ground wires all connected to the metal backlight frame...so wouldnt it work if i just connected them all together or i just get the metal frame and put it on the bottom of the box or cut the frame down so it would fin and connect the ground wires?
thanks

veterans of this place will say this is a pet peeve(sp) of mine. The issue seems to have died down alot lately, anyway.

Do NOT add any non factory wires, untill you have tried it first without them.

Every monitor ive seen on here works just fine without any ground wires added, in fact people who just added grounded wires for the sake of adding them reported problems.

There is only one model LCD, made by BENQ that requires additional ground wires, and I think that is an engineering mistake.

With that harness you showed in the pic, that one wire with the ring on the end is cleary a ground, so attach that, where it was before you took the monitor apart and youll be fine.

thank you very much.. but that one wire with the ring went to the metal backlight casing which im not using now. So do i just leave it alone or do i put the metal casing in the projector box also?
thanks
