checks in the filter that no continuity before the busting can be shortened

Good Companions I ask for your help to be able to save this Boss Model BV7460 stereo car one day and it did not start and I checked and it turns out that I was burned from some areas I will leave photos below the problem is that an SMD capacitor was charred and I don't know what value to put in addition to some burned tracks and looked for the diagram for service but I do not find it anywhere so I resort to your precious help if someone has the model and is so kind to take photos or tell me which components are going I would appreciate them I would rather leave them photos to keep an eye on thanks for your attention and an apology for your time with no more trouble:
In the problem image, remove the capacitor to show the complete fault

if you see the pin + of the capacitor it comes from the CON6 connector of there it goes to the smd c98 capacitor and it does Y with what it is the tracks after the fuse resistor that mentioned me that it goes there but the value or volts nothing is the FB12

Check the smd type transistor can be short and that proved the flash that flew the track and condenser

Do not remove the capacitor so that the fault is seen is one of 100uf at 16v above fb12 where the damage above is supposed to be a fuse resistance that they told me in a previous post I already checked the IC11 and it is not short

but I will try the bridge to see if it works I will comment what happened when I put the bridge thanks for your contribution bro

Do not connect directly place a car bulb those carrying the parking lights.
place it in series with the power supply and if you have any short the light bulb will turn on at% and if it gives you very little brightness it means that you do not have a short and your radio should turn on place it in a radio function already under vulumen

I connected it and the bridge cable melted, I will look for the short film, I hope it is not burned, nothing more xD then I tell you
hace 6 años
the spotlight turned on at 100 and then the cable was cast with the bridge was one of those that bring the headphones on the xD cable and the stereo turned on but the touch screen tomorrow will remove the diode by the way an integrated heats up too much maybe it is due at voltage

No, it is not due to the voltage that warms you up, maybe it is this ic that has short.
Turning the focus on% means that you have a short
Place the bridge with the same thickness of the track that you have open and without connecting it Czech ohmeaje on this track with respect to chassis ground, it is almost certain that your tester will mark you a very low value, if it is affirmative only check the components That they are a soldier on this line including the ic that heats up.
.The focus should be a few wats.o place a 600mA eliminator at 12v comments

Checking I found that the diode is short and I have not changed due to lack of time but tomorrow I change it and check what Maeiano tells me before removing the ic

If it is short, change it, it will prove that all the voltage goes to tender, proving the fault you have right now.

if it was short confirmed Thank you for your help and on and everything but does not respond to the touch of the screen but minimum already lit thank you very much
