Fixing black screen 32in element
Monitor turns on but there is no image on the screen at all. Backlight comes on for a few seconds and then goes out, monitor goes to sleep.
Ok so I found a post searching the problem that said to remove a couple capacitors because they were shorting out. This person used a thermal imager to find the problem. SMD capacitor CD4 is shorted. Then another CD5 on the back side
I removed the one above the heat sink (CD4) and still didn’t work. Removing the second one on the back side brought it back to life. Yes, my black Friday deal was saved from the scrap heap.
It’s easy to remove the back cover, First remove the stand then start along the bottom unsnapping. Then rotate the lower cover up and lay it flat
You have to remove 4 screws on the board to get to the backside but you don’t have to remove any wires
