My display panel went "dark". I ran through the flow chart from Hayward and all appears fine so I assume the panel just died. Wondering if anyone else experienced this?

Hayward Progic display panel issues
- Thread starter will
- Start date
Any idea how old the panel is? I hope this will bump this in front of some eyes that know the answer.
Will, how old is your prologic, when was it installed and by whom? you do not have automation listed in your signature? Is this new?
Thanks guys- it was installed by previous owner (professionally done) but my guess is around 10 or so years old. I mistakenly put LED and I meant LCD display. The pumps still operate on the programmed schedule- it's just gone dark
i'm guessing it's a color graphic lcd? among other things, the lcd itself could just be dead, the driver on the board could be dead, the backlight could be dead... check the backlight - if you hold a flashlight to it (try different angles) can you see anything at all on the display?
oh, and give us the model number if it's got one

It's the PS-8. It's not a light issue because pushing individual buttons does nothing so the whole display is dead
hey Will,
Ahh, I assumed you had an AquaPod type thing with a color lcd, and by "gone dark" I thought you meant black.
Does your remote look like this:
https://sunplay.com/products/hayward-prologic-ps-8-white-wired-wall-mount-remote-aql2-ww-ps-8
That one has a 16x2 character display... it sounds like that's what you've got, and that yours isn't displaying anything at all.
We just saw this sort of thing happen to a Pentair Suntouch... if you feel adventurous, crack the thing open and take a look at where the lcd mounts to the board. It could plug in, it could be soldered, or there could be a flexible elastomeric strip connecting it...
1. if it's plugged in, unplug/re-plug it a few times to try and "clean" the connections. you could clean the pins with an eraser, a clean scrubby or 1200 grit sand paper
2. if it's soldered, use a magnifier to see if there are any bad solder joints (any cracked, discolored or different looking joints)
3. if it's got an elastomeric connector, remove it carefully with tweezers (don't touch the ends of the connector), clean the board with isopropyl alcohol and re-assemble. you can also clean the pads on the board with a white draftsman type eraser (i've fixed many dead fluke multimeters this way)
I hope that is more helpful!

@Tom- thank you. I tried unplugging it several times and didn't notice any bad areas. I ordered another but would love to fix this one (they aren't cheap). Do the displays just go out?
Thx
Thx
i bet it can be fixed...
i have seen lcd modules die and that's probably the case here, but it could be something else like the lcd drive voltage or contrast circuit has failed. first we need to find out what kind of lcd it is... are there any identifying numbers on it? (or include a photo of it if you can)
does yours have 16 pins? the 2 and 4 line displays used in the Pentair stuff are pretty generic 5volt, 16-pin displays (Pentair uses LED backlit displays, but if there's no backlight there's only 14 pins)... if yours is similar then there are many replacement units that should work.
without knowing what exactly you've got, this unit probably has the same pinout:

Thanks guys- ordered a new display and plugged it in and all is good. Thx for the input!!!
