I have a Panasonic TV Ct-27G30T with a shorted diode (D808). It's marked with only "54 U". Does anybody know what it is or what would sub for it? Thanks

Re: Diode ID help for Panasonic TV
"54 U" doesn't yeild anything useful on google, bug "54 V" does as it's a common voltage for diodes. Could it be a V and not a U?Originally posted by aceshighPresonus Audiobox USB, Schiit Magni 3, Sony MDR-V700 -

Re: Diode ID help for Panasonic TV
Thanks for the replies. I'm at work so this is from memory. It's off the switching regulator STK730-020 close to the flyback. It doesn't look like a 54V it's definately a "U". Also not glass but Germanium on the small side. ThanksComment

Re: Diode ID help for Panasonic TV
Well, Panasonic finally got back to me with the part number. "Bohagm000006" Doesn't help much for finding a sub.Comment

Re: Diode ID help for Panasonic TV
Humm Ok at a guess most likely their in-house part number.
Can't help you directly, sorry
from a bit of googling,this pdf..... but not much luck on what it might be
PDF link on the IC here
(probably have to click 3 times to get to pdf, 3 pages to get to it)
I suppose the circuit would follow somewhat what is shown in the pdf...from that you may get an idea of were it fits in the scheme of things
(bear in mind,would be more components then shown in reality, with what you got)
maybe a pic may help,You step into the Road, and if you don't keep your feet, there is no knowing where you may be swept off to." Bilbo Baggins ...Comment

I picked up a Panasonic NH-P70G2, though it would apply to the NH-P80G2, NH-P70G1 and NH-P80G1 models as well, as maybe some other models. This one was coming up with a H86 error. After lots of testing and googling it was an error with one of the thermistors in the condenser area.
The attached French service manuals is incorrect, TH11 is gray and is a 95k thermistor and TH12 is black and is a 35k thermistor.
In my case TH12 was bad. I was able to get a 35k thermistor on AliExpress. It's 6mm in diameter.
Unfortunately the whole machine has to come apart to fix it.

Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing hereπ€?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting π.

Hello, I am looking for help to replace a damaged diode. The tristar was replaced and a diode was damaged in the process. I have a picture of the diode but dont have an exact donor. I mostly have macbooks for donors and only a few ipad and iphone boards. Diode part number: DSF01S30SCAP
Im not sure where to find the ipad board number. Anybody have an idea where else this diode is used on other boards? Thanks.... -
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?.
ββββ
The led strips has 9 6V leds.

Hello experts,
Can anyone educate me on how to test MBR3045CT and SR3045LCT Schottky diodes? I'm totally a newbie in electronics, so forgive me if I have cheap tools. In my effort to repair a Gigabyte PSU, I stumbled upon the two diodes, which I suspect are leaky. I tested this with my two cheap multimeters and the newly bought LCR-T4 MC328, and I got confusing results. Below are my test results.
