I measure at the end of R417 and there is continuity. Very low resistance. It seems like when it is all connected, the voltage drops Check the pic.

Enjoy !!! If you are in Spain, U're welcome home

Hello dear colleague, any idea or suggestion regarding the measurment I did?

Hello, I disconnected the connection in between Q404 and R417. The result is: that the side of the transistor now voltage is 3.1V instead of 0,8V. I checked R417 which is similar to R415 and give the same Ohm measure. On the other hand even is voltage passes thrue R415, that line should have...

Thank you very much, you are very kind.Tomorrow I tell you

Thanks in advance

Hello, here is the result of the measurements.

Hello, did you find out whre it comes this VDD_5R9V? I'll really appreciate your help. My best. Chris

Hi,all the lines VDD_5R9v are 0V, I need to race where it comes from.Thanks and 73 fro EA zone

Hi, what is "sec" ?

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

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.

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

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

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

Hello, Im back again. I received the new IC406 and it was changed immediately. The results are the following; PIN4: 1,25v, PIN6: 3,25v. Regards

Hello Mike, I removed Q401 and not voltage on Pin 6. L401 3,3V on both sides. These are news. So eventually, something is wrong with Ic406 while VIn (Pin 4) is 3,25v and not out thru PIN 6. What do you think? Best regards.Christian

Great. I'll check removing Q401 and replacement will take time to find the items.Tomorrow information.Dziękuję

Hello Mike, the measurements without VR-C Regarding the IC406 (L164) pin1:0v, pin2:1,48v, pin3: 1,34v, pin4: 3,25v, pin5:0v, pin6:0v R417 0v--0v L402 3,08v-3,08v this is the information,What do you infere from this. Many thanks in advance Christian

thank you make, I hope tomorrow will check again. THKS
