Unexpected rain+heatermeter=only half of LCD display

[James VanDever]

Hello I've had a heatermeter for a few years and couldn't be happier, last night I set up my bge for some pork butts, it seems we had a little rain last night and now my LCD only displays the left half of the screen, I took everything apart,reseated everything that can be,and brushed off some minor corrosion that was visable. Any ideas where I should be looking for an issue with the symptoms I'm having? Thank you

Unfortunately the LCD board would be the first on my suspect list. I would try blowing out the area between where the LCD and HM boards are sandwiched together with some compressed air or hair drier to make sure there isn't moisture trapped there and shorting things out.
