So, 2 days ago, i bought a 7 inch LCD kit with touch screen and the controller board.
I power the board with a 12V 0.5A power supply.
Everything worked pretty good, until yesterday the LCD start to turn off randomly and i have to manually turn it on again.
So i thought that my power supply is need more Amps (as most of people use 12V 1A, but i see some people use 5V 1A and worked).
This morning i buy a 12V 1A power supply, i connect it and it worked for about 20 second, then the LCD turning off again.
Then i saw my power supply light is flickering, so i immediately disconnect the power and found out that the chip (RTD2660H) is getting very very hot.
I tried to resetting the power like the old power supply, but still, no luck (and yes, the ic still getting hot even if the new power supply light does not flicker).
I tried to use the old power supply but there is something strange, this time my old power supply light is dimming.
I had been searching a lot today (hell, i wasted the whole day trying to figure what is the problem) and asking my friends, my friends said that it could be a short (but i dont see anything shorted) or too much current, but i still do not know what happen here.
So... help me.... =(
