content: It's only been one day, but, to answer your question:Providing a model number would help, a picture, a picture of the inside of the unit, what voltages have you measured, etc...?

content: Thank you, Bostonman.I'll get back to you with more details, but it's unbelievable that there is 212 views and no contributions! What's going on with people?!Regards

content: The details are what give you anything to go on. Unless someone had your exact thing with your exact fault and had a canned repair tip ready, what meaningful information could you offer without details?Also I think "view count" includes reloading the page and web crawlers skimming over it, so I don't think it realistically represents an individual interested human's view.As for me, never heard of the company, haven't seen the unit, but the next step would be checking to see if those good voltages get to the devices they're trying to run. If the power supply is fine but the main board isn't on, maybe there's a fuse or secondary regulator somewhere, or maybe it is turning on but the thing you're using to decide if it's on (like a screen turning on), isn't getting that far.

content: Thanks to all.DaJMasta ! you are right i discover that the vertical board who is connected to the screen has some fuses smd i checked them all are good. the question is that the power supply is ok, so i think is almost the firmware issue but i can't reload the firmware and the unit not on ?

content: What you wanted to say is"Hello Forum, I have a device called a BrainChild Paperless Recorder model number PR. The unit does not appear to be functional, but I have checked all the voltage rails I can find on the board and they seem correct. Does anybody have any suggestions?"I think this isn't exactly a common piece of equipment, there is probably a low chance that somebody here has seen one, let alone has had one with the same fault.My suggestion, not knowing anything about this device, is to be first certain that it's not working rather than it just being that the backlight is dead.Also, give that poor Fluke a wipe down.

content: After we've sorted out what is wrong with people we can start sorting out with is wrong with your paperless recorder. As expected there are no schematics available. But there is no reason to panic yet.Your job now is to take pictures of all sides so people can see what this box is all about on the inside so people can guide you trough some basic trouble shooting. People in here must be able to identify components and if the machine is made with different boards people would like to see how things are connected together.-Is the power supply good? You've shown us some measurements but they are to some extend meaningless.-If power is good, is the micro controller or whatever it might be running?-If not, is there a battery back up with an empty battery keeping reset stuck or did the battery leak somehow and eat away some parts of the PCB?-If the brain is running, is the display back light still ok? (You might be able to see something by shining with a flash light into the display if the back light has passed away)...There are some very capable people in here who will recognize every part in that box and even know how they are usually connected without looking it up on the internet. It all depends on you.

content: Hi Temperance!I'll delve deeper into your recommendations, as you were right — I missed something important: locating at least the microcontroller and its pinouts, and reading Vcc against GND. Thanks a lot for your explanations and details.Great Thanks and Regards

content: Hi Poroitunfortenately i've done it early last week but it don't give anything, in this case as Temperance said, i have to be sure about the hardware circuits included the µcontroller are all supplied because the device is dead, and just after controlling the voltages at that time i will see if lcd back ight is the real issue!Regards

content: Good day PoroitThank you for your message and your assistance. Since that day, I haven't found the time to perform additional voltage checks, but I will definitely return to it. I saw your communication with Brainchild—excellent—but unfortunately, the device still won't turn on.
