| 5Volt switching regulator made by Taiwanese outfit Aimtron
Manufactured part number AT1796-50 Probably not easy to find locally. I have had good luck with utsource.net for the oddball stuff but it will take time coming from the east. |

| checking the screen after replacement - no change
I checked the power board- I could see that the 5V pin show 0v ( 12v OK): 
testing the diode (disconnect 1 leg) show it is fine. so I suspect the U13. ( is it a voltage regulator?) need help with that 
the part number is:1796-50a G3417A thank you |

|
| HI
trying to reaper the Aegis 152TA 15" touch screen. 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) 
new cap (22mf 50v) 
to be cont.. |
