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.

The read out is stuck on no sale


The circuit board may have been jolted by a power surge and a diode is stuck in the on position. The pathway is only in one direction and thus it can't be reversed. Replacement may be the ony solution.

What causes my picture to go pink all of the sudden ?


Examine the screen with set on and color set to zero--stand back and look= is screen pink to red color?

If so it may be a common issue on this Hitachi.

Usually it is an adjustment inside the set of the red screen control needing to be turned just slightly down---these are known for the red control "drifting" just slightly from time to time--answer is based on model number indicated here.

Mitsubishi cs-35607 - Everything is Red


This is a known issue which requires the replacement of up to 3 chips and the addition of a modification ( diode)
The IC's are AN5268K
The modification requires the installation of a diode 1N4148 connected between diode D6XAL and Diode
The 1N4148 anode to D6XAL anode. The cathode of 1N4148 should be connected to the cathode of D6F04

You should also re-solder any bad connections on the board.
If you are at all unfamiliar with replacement of IC's or hesitant you should have the work done by a qualified technician

The unit SC_HT67 don't turn on


It sounds like a faulty voltage regulator or diode on the power supply of the stereo. If you can check these things yourself also check for dry joints before checking diodes and regulator/s. If not trust a competant techmnician. Good luck.

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?
