HI
trying to reaper the Aegis 152TA 15" touch screen.
https://www.electro-tech-online.com/custompdfs/2012/01/Aegis2015.pdf
as I connected the 12v power supply wrong polarity, I suspects I damage it
the problem: not turning on.
things I tried:
opening the screen, I sow a bad capacitor (exploded), replace it with different capacitor from shop ( look diffident, but I have been told it's same):
old cap- (22 25a)
**broken link removed**
new cap (22mf 50v)
**broken link removed**
checking the screen after replacement - no change
I checked the power board- I could see that the 5V pin show 0v ( 12v OK):
**broken link removed**
testing the diode (disconnect 1 leg) show it is fine.
so I suspect the U13. ( is it a voltage regulator?)
need help with that
**broken link removed**
the part number is:1796-50a G3417A
thank you
