I have a BLH-Y for my 13,000gal pool. The Display board shows all light's and the digital display is blank. What is the cause of the problem?
I bought the house last year and pool was already intalled. Had no issues with it until I started to open my pool this year.

Welcome to TFP.

Show us the inside electronic board of your BlueWorks SWG Controller. Prior models were Hayward Aquarite white labeled products but Hayward does not have a LED version like you have.
 
That looks like an Aquarite board with a different display board.

Remove the display board. While it is off, take a picture of the board. The Wiki explains problems with the thermistor in the upper right and with burnt solder joints on the back of the board.

Check the back of the board and take a picture of that.

Then reassemble the boards. Sometimes, reseating the display board is all that is needed to fix problems.

Post the pictures of the board and let us know how it behaves after reassembly.
