The first card was burned destroying a corner of my display.
For Best BST-863 Improved Control Board
The first card was burned being in fire two resistors and a cap. I didn't notice then that this accident damaged my display.
The seller sent me a new card free of charge and it worked this time but at the price that the display had been damaged in a corner when the first board burnt.
This investment has been one of the most expensive in many years. I thought that I was doing a clip mounting this board in my unit but it created more problem than solutions. Now my device is working but with a damaged display as result and it's impossible to get a new one as spare part from China.
I can't blame anyone. It was totally my fault for taking such risk. Anyway, I am so thankful that the seller was trying to support me during this issue but the final result is what counts: a damaged display.

Hi Alex, this review kinda disappoints me.
When you contacted me and told the way the board was misbehaving I found it strange but immediately started to message you troubleshooting steps so I could better understand what was happening in order to provide you with a possible fix. You then sent me the pictures of the burnt THT resistors which completely left me baffled as this is something that never happened before and seems very improbable to happen as it is a very simple triac switching circuit and all the components are well overrated, I thought maybe you mixed up the THT resistors when soldering or there was a big voltage spike on the mains power. Nevertheless, since I don't like unsatisfied customers (and don't like pointing fingers either) I immediately fully assembled a replacement board (even though you originally bought the kit version) and sent it to you the very next day free of charge of course.
Today you sent me the pictures of the cracked corner on the display and only now while reading this review I understood that you are trying to blame it on the board... Now here I have to say this makes no sense. From what I can see on your photos the LCD is even cracked on the opposite side of the resistors... In my installation instructions (both in PDF format and in the video) I make it clear you should check if the LCD is well positioned before tightening the screws, unfortunately it appears you skipped this step.
I believe I did everything I could to help you and I am sorry that in the end you are not fully satisfied.
