...inut power circuits have a failure. Electrolytic filter cap and the votage regulator (probably a 7805 type) may have failed. IF the 7805 failed, then there is likely a short on the 5 volt supply
...the power supply is a switching type that has some three terminal regulators after it such as 7805, 7815, 7915. These have thermal protection in them and one may be shutting down. Use circuit ...
...the PSU is used in other mixers. Suspect a broken circuit trace or broken solder. If they use a 7805 three terminal regulator, check the solder around those pins... Berhinger does NOT release ...
... SB (logo) 0609 E228731 94V-0 S168 BF0102 The C23 part is a capacitor and the 7085 is more likely a 7805 which is a voltage regulator. The regulator is easy to find. For the capacitor, you will need ...
...the TOP245Y, TL431AC and the P6KE200 diode. 15 + and - rails came back, no 5v. replaced the 7805 regulator......all good.Now all I have to find is the original short which caused this. I am ...
...the switching power supply has multiple voltage outputs. We checked the 5-volt regulator which is a 7805, it isn't getting any input voltage to the regulator and we are not measuring any other ...
...+12,2 V, but I measured 14 V. This voltage is lowered to + 5 V by a resistor on the FW board and a 7805 regulator. (Not very efficient!) But as far as I can see, the FW voltage is not the problem ...
Question about Music
I have a Kurzweil pc88. The unit function but the power board 7805 voltage regulator overheats and eventually shuts down after 7-8 minutes. All else appears functional. Any suggestions? I have removed
...much It is likely soldered into the circuit board. It may be any of several part numbers such as 7805. Try to read ANY number you can off the IC itself... the last two digits are the voltage... ...
