What the voltage value of zener diodes? (D825, D826 red,red,gray) and D823 (red,yellow).


This table is the information used by MOST diode manufacturers that use color banding on diodes. Most manufacturers stamp the ID right on the diode but some do use color banding as the method of identification. For purposes of alignment, the side with any color band closest to either side of the diode is the equivalent of the left side of this table. The three examples in the table when associated with the values in the lower table, are identified as 1N64E for the top diode, 1N452G for the middle diode and 1N4762 for the bottom diode.
See the color coding

In panasonic modeltc-29sf3 pls give me the working voltage of zener diode with color code gray red red and red yellow in power supplyn section


just read the model and then google it, beside, if you short them, you need to replace them with same value, and this will be determined by the circuit, if you did not change the circuit - just buy two new diodes and install them, do not bother with voltages as they have some tolerance and type will determine it.

Schematic for pc78xL won,t turn on


there gould be a number of reasons for it not turning on but the one I am thinking of is the reverse polarity diode. If it is burnt your radio will not turn on look in the area of your where your power wires come in .You should see a single black zenner diode.Replace it and it should turn on .

UNKNOWN VALUE OF VOLTAGE ZENER DIODES


I was not able to find any service or schematic for this model. The colors means that the value is 22.6 volts zener diode with the other blue band indicating where the cathode is.
Could you tell me where or what other components this zener diode is connected to?
