Re: pf0581 223nl substitute
PF0581.223 22uH 1.6A 84mohm. It's about a 10x10mm part.
Pulse PG0015 series is taller and 1.95A 100mohm but nobody stocks their parts.
Soldering this thing is the hard part, some have pins on the side, some underneath. Check the PCB footprint would work with many other inductors in the popular 10x10mm league.
Bourns SRU1038-220Y 22uH 2.3A 56mohm
Wurth 7447798221 22uH 4.7A 37.3mohm

Hello again Community
Anyone verse on how you go about choosing a substitute mainboard for your TV repair. Like the chap in the video below sometimes a 1:1 replacement board is too expensive and reballing a mainchip(s) maybe outside of your skillset
. In the video the poster states one needs to match the replacement board with the SMPS, T-con (if not built in) and panel (and substitute cabling be also be required).
I'm very interested in choosing a suitable replacement board for any model or make of TV and the general (or detailed if your willing) step this entails....03-23-2024, 02:55 AM -
When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.
Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.

Hi to all!
I want to know, if somebody knows, with wich mosfet can i replace 28n03 (i´ve didn't found it like that)
VDS= 30 V, ID = 28 A RDS(on) < 18mΩ @ VGS = 10 V RDS(on) < 30mΩ @ VGS = 4.5V
Thx in advance!... -
Hi All,
Need help sourcing a substitute for ACT remover G-450 in Canada.
Removing glue from Flex Cable on LED TV that I dislodged so I can resolder with ACF tape.
Can someone confirm if acetone will work?
They will not ship to Canada.
Thanks for any help.... -
