Hello, see if tnesion arrives at pin 1 of that integrated has to walk between 280 and 300V. If there is not then the fuse jumped, if there is later we see.
Well now in the output conetor P9701 check if there are any of the voltages, 1-4-6-10-11-12 are GND, 2 -12V, 3 + 12V, 13-14-15 + 35V.
of the P9701 is all low does not give the cavity I think there is something that fails but the Q101 that piece is heated by the short friend
If that transistor heats up, three things can happen, it is short, the eeprom or the microcontroller is damaged since these components are fed from that transistor and if it heats too much it is because too much current circulates.
One last question and thanks for the help. if it was only a short in the part that we started checking which would be the most prone to damage remember that it was a damage of mine and not of the team I was welding and by mistake he made a tick as if it was in filter discharging of course that was not with the current if you asked what was soldering was the STR that was loose of course I don't know what happened to me
It is impossible to know that, since the transients that are generated go to all the windings involved and from there to all the DC voltages that leave it, as it can be there or it can expand forward. On the other hand, if said transistor is heated, it is because the source associated with IC902 and T902 is apparently working.
