Lg PF1000u projector, please admin update the title. Thanks
Hi everyone
My projector died out a couple of weeks ago.
It's not techically dead, I can turn it on and I can hear it boot it properly, can turn it off as well, the fan boots but there was no image, no led turning on at all.
Yesterday I finally had the time (too busy at work) to disassemble it.
I opened it up and found out that the led drive part of the board had a short and had burned out. The part is the dlpa3000d from texas instruments.
It appears that pins 5 to 10 got a short and burned down, hence there is no power to the RGB leds.
Do you think it is the driver itself that went bad or there is another short on the board probably?
I have attached the dlpa3000d technical data sheet and some pictures of the led board.
Thanks
