I have attached all the pages that have to do with the PCB. I will also like if you can tell me the equivalent of the component in through hole components. ThanksI think the circled parts are ceramic capacitors.
I also thing there must be a page 2 to the schematic.
Thanks for your effort so far. Here is a PDF version of the schematics.Frisky2good,
Your schematic "screenshots" are mostly unreadable on my PC, the resolution of the JPG files is a bit low.
However, when I click on the original picture of the board, I can clearly see that the unknown components are adjacent to IC2, IC19, IC25 and IC30.
So if you can have a look at the schematics on your PC, and find those components, then post a higher resolution version of the appropriate schematic, then we may be able to decide on the nature of the unknown components.
I agree with Ron.I think the circled parts are ceramic capacitors.
They are actually 5. I got blown beyond recognition so I asked someone that has the same equipment to send me a picture of his PCB which confirmed that the missing component is similar to those other 4. I was also fortunate to find the schematic. Since there is noone around here familiar with SMDs, I decided to seek help online. I have attached the picture of the spot where the blown component was. Top right where the arrow is.The regulators are on page 5 of the diagrams, the capacitors are either 470nF or 100nF, depending which regulator they are on, and if they are on the input or the output.
Why do you want to know anyway?.
I can do that and upload theSome surface mount ceramic caps made by Murata have that red body - eg. some in this list:
Other pictures sometimes show the stronger red as with the ones on the circuit board.
Can you measure one of the good ones, the physical size in mm or fractions of an inch?
I did not power it after blew up but I will try it tomorrow. Thanks a lot. Can I replace it with a 100nf, 15v through hole cap because SMD components are not available here?Try a 100nF, it's most likely not very critical anyway - probably just a decoupler - does the unit work without it?.
... But try to clean the area as best you can first, to remove all the blackened stuff and any possible conductive fragments that could cause further problems..Yes, just stick a normal cap across the pads.
