    Were any of the numbers the chassis number and if so can you give me the value of the zener diode at D982?

It should be at the back cover, just where the model number is. If you have the TV open, it may also be found inside, maybe on or around the tuner area.

    I look for the service manual for this model, but is not available anywhere unless you pay for it.

    If you want to buy the schematic diagram, I can send you the links where to get it.

    Is any way you can read the numbers from this Zener diode?

Equilent for a zener diode (RD 30ESB2)


Zener diodes are invariably used as low power voltage regulators or as a voltage reference for voltage regulating circuitry.

Zener diodes are sold by wattage and reference voltage by numerous component suppliers and constructor stores and in theory the voltage is marked on them, though difficult to see and easily defaced.

Finding an equivalent for what appears to be a manufacturer's part number presents a rather difficult challenge. The official service sheet will probably provide the required voltage. Without that information you will either have to purchase the component from the manufacturer under the part number or experiment until the required value is discovered.

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.

My hitachi 29in ctv power supply 110vac had a problem on zener diode will blown if we switch on the tv. what spare parts to change so that the power supply zener diode will not blown again and the supply...


The secondary output voltage comes out from is more than it should be there. That is why, the protection zener diode blows off, as soon as you switch ON the set. First find and repair the power supply regulator, for correct output voltage. Refer its repair book for details. After repair include the zener diode in place. OK.

I have a sansui tv set with a power problem . MOSFET W11NB80 in the power section is completly blown . can t get it in the local market in kenya what is the equivalent value. its a crt television...


Hello

W11NB80 is an N-channel 800V-0.65ohm - 11A - rated Metal Oxide Semiconductor Field Effect Transistor [MOSFET]. You can use the folowing substitutions for it
[ 11NM-80, 12NK-80 & 10NC-802]. All of these are its equalent substitutions.
Before replacing the mosfet, check the entire power supply secion for any short circuit, or zener diodes faults. If any of the zener diodes are fused, it will run out the MOSET you sumstitue again. Check it keenly. Unsolder one end of each component, lifit it up a liile from the circuit board and check. Especially zener diodes must not show any leak in 100Kohms range. It is best to replace them all I suggests.
I don't know about its availability in Keniya, yet you try to get it from any electronic spare part shops. f feels any difficulty in getting the same contact [E-Bay] site, they will reach you the exact component at your doorstep. Ok.

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?

The Sony part number for these diodes is 8-719-108-12 and yes they are 9.1 volt zener diodes @ 1 watt. I have the service manual for this set if you need it put can only send a large file like this trough a proggy called pand, so if you go to pando.com and get the proggy and leave youe e-mail addy I will send you a copy of this service manual. Good Luck
