Re: Panasonic TC-42PX14 Zener Diode
Ok, the IC5401 is a 9V voltage regulator, so the Zener Diode may be 12V Zener.
So next thing for me is to find out what generates the F15V source.

Re: Panasonic TC-42PX14 Zener Diode
Sorry guys, did not respond yesterday. Ended up in hospital
with Great Pains in Abdomen, after Ctscan, I have a Inflamed
Colitis. So much for that.
yes, the color is red, black green.
I am not getting 15v to the diode or to IC5401, reading is
5.4v to both components.Leave a comment:

Re: Panasonic TC-42PX14 Zener Diode
If it is used as a protection, that means its Zener voltage point will be higher than the output voltage of the IC5401, so the circuit should still function without it and you can also measure the output voltage of the IC5401 and then use Zener Diode that is about 2V higher than the output voltage.Leave a comment:

Re: Panasonic TC-42PX14 Zener Diode
I guess theirs two ways we can attack this, but if your ability to see the diode as well could ultimatly swing the other. Just remember your dealing with a LL-34, hope this helps.Leave a comment:

Re: Panasonic TC-42PX14 Zener Diode
Panasonic part number B0BC01100001. However they do not say what voltage rating it is. Its on the output of IC5401 which is the Sub9v. Most likely used for protection. Just guessing maybe 10v or 11v. Input to IC5401 is 15V.Leave a comment:

Panasonic TC-42PX14 Zener Diode
Hello, this Zener Diode is on the A-board, it is part of
the 15v rail that leads to IC5608 and 5607. In an earlier
post I have attached the Schematics.
Can someone identify how many volts this Zener Diode is.
Panasonic parts does not identify the Diode. Suppose they
want you to buy from them. Unfortunately they do not
stock it.

Hello everyone, I'm repairing an LG TV backlight and I noticed some strange behavior when I touching the backlight strip with a missing Zener diode.
So I replaced the leds on the strips and they seemingly working fine, but soon as I touch the strip which has a missing Zener diode the whole backlight turns off for a few seconds and then turns back on.
Is this caused by the missing diode? If so what kind of zener diode should I use to replace it?.
The led strips has 9 6V leds.

I have bought this Zener Diode for this project what size and wattage resistor value do I need to use to get near 50 watt output
I bought this from an eBay seller but unfortunately they only had one
I bought three from Vetco Electronics these are Sylvania ECG5185A 9.1@10w A to Stud what size and watt resistor do I need to use to get near 10 watt output
I bought three of from them to also make battery packs with this output power limit in mind
I want to use this battery pack and turn it into a 9.1 output battery pack output to eliminate using 9 volt battery... -
Hi, I'm looking for a bit of help trying to fix the audio unit from a Maestro Mayhem 4.1 gaming chair please.
The chair has a few speakers and vibration motors. All was well, for a while, but now the sound is gone.
It may be significant that I discovered my son was powering it with a 19V laptop charger when it should run on 12V - it did fully work, for bit.
I think an issue could be a zener diode (or capacitor) which has shorted out.
The board's bluetooth input still works, the vibration motors are working, so is the line out socket but not the... -
My Element 32 inches tv (ELEFW328B) lost it's backlight (confirmed with a flashlight test) and the connector on the PCB (it has one board that has a processor chip, switch mode power supply, and backlight circuit) that has the two wires that go to the backlight LED strips has a very low voltage (28-29 volts) when turned ON, in my opinion.
Started testing components and found an SMD diode or zener that is shorted (even zero fusing resistors read a few tens of milliohms, while this thing reads zero).
I put some pictures here to show that it is labeled "M7".... -
Hey there guys. I've got a Corsair power supply that's come across my bench dead. I usually don't mess with power supplies, but it's a slow week so I'm giving it a whirl.
Taking it apart I heard a screw rattling around inside, and when I got it apart I found a couple blown components near what I think is the 5VSB area.
There's a 22ohm resistor that's melted and open, but it still has the bands.
The other part is a zener diode and it's top went to jesus, so I can't read the marking.
It looks like the diode connects the source and drain of a TNY284...
