If it's not blowing the fuse in the car then I guess it wasn't drawing a huge amount of current. Check the power wires going into the radio and look for something loose. My first guess is your loosing voltage across a bad connection somewhere and a

Hi Folks, This is a totally speculative, if not cheeky post. I know very little about electronics, but I think you guys do. I have a problem with my car radio, that I'd really like to solve, as I cannot buy a new one where I live (Brazil), and I th

What is happening is your bench supply is unable to supply enough current so the voltage drops. When you turn up the volume knob your asking for more current and the voltage drops more (the led's in the faceplate dim). It also sounds like when you

If that's the case, it's most likely the radio is bad. Again, I'm not clear, but it sounds like using the MD is the trigger to shut the player down: * Stop using the MD. * Fix the MD or some of the associated power supply regulation circuitry. For

Thanks to all of you. This is very kind. I'll have a good poke around the circuit board for loose / hot components - good tips. I think it might be a throw away job, but I thought I'd give it a last try. You guys have actually given me much more

You right Simon, this forum is not for that type of question, but since you have been polite and desperate, i'll shoot some help. Your right, sounds like it is the unit, there is probably a component failed that is shutting down the unit when it gets

Thanks a lot for the reply. The power supply I'm using (12v) is from an HP scanner, so I guess it's always likely that it's not man enough for the job. There were no fuse problems in the car, it just dies. As it is the same problem whether in the

simon- davef is on the right track. 1st year electronics courses teaches us that you should always check the power supply first. In this case, the power supply in question is not your power source but the regulated power within the unit. I suspect o

Hello all, Can anyone know what influence has on RF/HF components when using PCB with OSP coating? We are now manufacturing our RF components on PCB with ENIG coating ,and want to use OSP instead. By the way:If anyone can send me an article on this s
