[Chris_1723]

Hello my friend, not working display
My question is, what are the right voltages Pin 4 and 6?
I guess mine are wrong

Hello Dear friend, here is the measurements. Thanks a lot for your comments

<cut> get new Q404 <cut>
Mike

As I wrote before. Replace Q404

 

[Chris_1723]

Hello, once I received the Q404 I changed it and I not working the display. I send you the voltages around Q404 for your consideration

 

[sp5it]

There is still something wrong with Q404 area. Voltage on it's output should be much higher.

 

[Chris_1723]

My problem is I do not have a circuit with detailed information to trace all the voltages. So far, you were helping me. And I don't want to bother you, but if you have all the voltages around I need to check, Please send it to me, I can check all of them and then we can discuss about it.

I checked all the Display unit and not 5V to LCD. My question is where it comes this 5Volts?
J604 Pin 12 ???
