All 10 screens are tested by pastec and anon.
Only one is working for a short time.
We opened 4 displays === > exchanging all power supplies with one that works to check if the rest of the screen is functioning.
CONCLUSION: Most of the power supplies have bad capicators (as thought). Ptr_ will go buy new ones in MBTronics.
- went to mbtronics buy a set of capacitors (the 4 capacitors which are bulbed-up on all boards we've seen x 10 times ) costs : 30,10 EUR (took the money out of cash jar)
- replaced these on 3 boards : 3 screen working fine now
