DLPDLCR4710EVM-G2: EVM status : Connected , turned off and won't turn on by pressing switch 21

Langston Chang

Hi sir,

I had same problem as following thread e2e.ti.com/.../597582.

Power is on when switch the mechanical power switch, but projector is not on when I press the push button. There is no signal from proj_on when I measure the test point. Push button should be fine. Seems like MSP430 did not send signal on proj_on. Please advise how the problem be solved. thank you.

Best regards,

Langston

Hello Langston,

Thanks for using the DLP E2E forums. I was unable to follow the link you sent to the other E2E post. Have you ever been able to operate this EVM?

Best,

~Danny W

Hi Danny,

great thanks for your reply.

yes, I can operate the device when I received, but suddenly it cannot work. I paste complete URL as following. FYR.

"e2e.ti.com/.../597582"

the title is "DLPDLCR4710EVM-G2: DLPDLCR 4710 EVM-G2 status : Contented , turned off and won't turn on by pressing switch"

In case you still cannot see it, you can search with the keywork.

best regards,

Langston

A quick question.

It was mentioned in a reply that users need to make sure the DMD flex cable has not been damaged.

Is there any way other than visual inspection that can check if the cable is intact?

if we direct trigger proj_on signal, the projector will be light on. The cable should be no problem. thanks for your remind.
