Hand set distortion

diverrob · 13th August 2006, 01:53

All:
I am looking for any advice on a problem I have experienced with my Evo display. The hand set started showing vertical lines through it on two separate dives. Both dives were aprox 40 min in duration and separated by over a week SI. It happens around the 30 min mark of the dive the hand set changes form the normal screen to one with horizontal lines through it. I can still read all of the info and can function through the menu as normal but the screen is distorted. Once I surface and power down the unit and restart the display shows normal and so far the only way to recreate it is to go for a dive. If anyone has any comments please let me know Thanks

Rob

P.S I am running the latest software update

Maybe you need a hammerhead Rob. LOL

That comment is not necessary

I'm not familiar with this unit (using the classic), but was wondering if it could be related to temp (like if its real cold). Have you tried changing the LCD to a lighter setting?

Hi Rob. I downloaded the new software and have done 12 dives from 70-200' on my Evo without a similar handset problem. I would call SDS and tell them what you are experiencing. My guess is that your head is going to take a trip to NH and then the UK. I would hate to have the computer display scramble up on you in the middle of a dive.

I have had 3 back to back cell warnings immediately after I surface from each dive. In each case, cell 1 reads high ppo2 at the surface after the dive. Sometimes up to 2.25 (which is not possible). This did not happen with the prior version of software. Air and 02 flushes at 20' show all is well with the cell. The cell is only 6 months old and is fine under all other circumstances. I wonder if this is also a software issue. I will switch it out tonight. PM me if you learn anything from SDS.

I am going for a dive today and was wondering how you un-install the new update on the VISION electronics. Has anyone tried that??

A friend of mine has had the same problem, except his handset went completely black at 15m on his ascent. This has happened twice before and the electronics are now on their way back to AP. He was lucky in the fact that he runs a VR3 as backup and was able to complete his deco stops, as the screen was completely unreadable.

Well I just got back from a dive that was :65 at a max depth of 110'. I had no issues with the display and all flushes were OK (had a little problem getting 1.6@20fsw). I have a email into AP so should here back this week.

With a different version of software ?

DANGER WILL ROBINSON!

A "pegged" sensor (which is what this sounds like, not having the SPECIFIC details of APB's implementation) is extremely dangerous.

While it is POSSIBLE this is a software problem it is more likely that this is a hardware issue - that there is a current leak between some part of the signal conditioning portion of the circuitry and the sensor input.

If that is happening it is very dangerous because it is entirely possible for it to happen to more than one channel at a time, and for it to happen at ANY time. This could leave you with all three channels "pegged" in the middle of a dive!

IMHO this sort of error is one that needs immediate attention - the unit should not be dove until you know what's going on, as the risk of a malfunction that leaves you without sufficient information to abort and surface safety (by other than bailing) is very real.
