IWB Gamble, what woudl you do.

[Stuart_C]

One of my promethean boards has failed and won't draw properly in an area of the board (a n area 6" high stretching all the way accross the boad about 4" from the bottom). THe board is 4 years old an our of warranty.

 

After chatting to promethean they say it's either the board surface or the electronics. Now I can replace the electronics for between £260 and £500 depending on whether I pay for an engineer or do it myself. The problem is if it's not the electronics I then have to replace the board anyway. So the question is do I just stuff it and buy a new board?

 

As I type this I'm leaning towards just going for a new board.

[p858snake]

how much would it be for a whole new board?

[mounters]

If you've got another board then just try the control box from that on the 'broken' board and see if it fixes it. They are easy to swap if I remember correctly.

[Stuart_C]

£1400 in VAT, delivery and install.

Replace the board - keep the electronics as a spare set - if another board goes you can try swapping the electronics - if it works great if not all youve lost is an hour of your time!

[webman]

If you have others of the same model, I would suggest buying the electronics board and replace yourself. That way, you've spent the minimum to find out what the problem is.

 

If it turns out that is not the problem, you have a spare electronics if it happens to another IWB. If it is the problem, you've just fixed an IWB at the cheapest cost.

I had considered that. I had aslo considered busting two boards.... To be honest I am inclined to believe it's the board's surface rather than the electronics. Given the problem stays in a specific area of the board and everywhere else is fine I would have thought that pointed to a physical problem with that area of the board rather than swapping a circuit board.

[Stuart_C]

If I have boards bopught at the same time and are the same model board (i.e Presenta Boards) but are different sizes, is that going to make any differnce if I swap the electronics?

[mounters]

It shouldn't do, I've only ever swapped on the same sized board though. Maybe worth asking Promethean?

[Stuart_C]

Just to expand my problem where the board goes wrong it basically puts it "spiky" lines rather that what I am drawing. It's as though the board is not detecting the path of the pen, instead it detect's the pen at 1 point then the pen at another and assume's the pen moved striaght to that point and draws a straight line. When I talked to Promethean this didn't take much explaining and the guy seemd to imply that it was a problem they new happened from time to time. Has anyone else had this? If so was it fixed by swapping the electronics or had the board surface failed?

[mounters]

Yes we've had this happen and it was the control board that was replaced.

[Stuart_C]

Rubbish! Accrding to promethean the electronics match the board size. Thus the 3 78" boards I bought at the same time are no good when it comes to checking the 64" board that's broken.

[ICT_GUY]

Unlikely to be the board, most likely the electronics.

 

The board is a grid of wires with very little to go wrong, the electronics are vulnerable to component failure.

 

I would however check the connections at the back of the board, see if there is any corrosion on the interface and clean the contacts with servisol super 10.

[Stuart_C]

I have seen it before where the two sections of board come appart. You see I would have thought that because it's all the way accross the boad in a section it might be some of the connections inside that part of the board.

Could you not draw a line 10" from the bottom and resize the projected image above that line

 

Now that's minimal outlay

[Stuart_C]

Nope. The staff are too small and can't reach the top as it is (and some cupboards stop me lowering the board on the wall).

[round2it]

did you reflash the firmware as we had a problem with one of our boards and a quick firmware upgrade did the trick it now works perfectly.

 

promethean said i had to replace the circuit board (papp) look down the firmware upgrade route before replacing it.

 

2pence worth

Hi,

 

This isn't the case - if the firmware on the boards match (i.e they are both 3.xx), then the electonics can be interchanged - as they are the same.

 

The only ones where this can't be done is if you have a 95" board, and a 64" or 78" board - it can't be done between these models of boards as the electronics are physically different for a 95" board (although the firmware is still 3.xx).

 

If it is definitely a 64" and a 78" you were thinking of swapping between, and if they both have 3.xx firmware, you can swap the electronics to see if this is where the issue lies - obviously this is done at 'your own risk' though, as if either set get accidently damaged, they can't be replaced under warranty.

 

Just my two pennies worth as well - I have seen problems like this because of either the board surface, or the elctronics themselves - theres no way to know for sure unless you try a replacement / known working set of electronics in the board.

 

Good luck with it though!
