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?

PANASONIC TC-20L3T


My experiance is to not put money into a TV that is over ten years old. TVs stress out their electronic components worse than almost any other electronic product. After 10 years, there are so many parts that are ready to fail that your are probably wasting your money trying to get any more life out of it.
Another option is to wholesale replace the main board by sending it to Module Exchange at 972-298-1212, or PTS Electronics 800-844-7871 ptscorp.com.
Be careful on buying a new one though. Often times, these new technology ones are much worse. Always Google the model number of the set you intend to buy and add the word 'repair' or 'complaint' to see if it is one of the many models that are customer service nightmares being produced by even the most reputable companies today.
Hope ya fix it!
