im looking to stock panasonic fm caps,as id like to stick with one brand,these caps are good in ripple ,low esr etc,is there any reason apart from the actual pysical size of these caps they cant be used in lcd tv power supplys,and main av boards,inverters etc?thanx!

fixed so far...376 lg lcd tv's,24 onn tv;s,24 panasonic lcd,16 jvc lcd,12 marshall jcm800 amps,refurb of various disco equipment lighting,old style disco decks ,and a flymo!
----------------------------------------------
please let us know if everything works ok if your tv gets fixed, as it will be and aid for anyone else having the same problem and wishing to fix it.it would save people clogging up this site with topics that are duplicated,and can be found easily using the search function.,and taking up valuable space.enjoy your fixed tv!,hopefully! -

Yes, if specs don't match -
Re: stocking capacitors,panny fm
Many of us in the Monitor forum use them exclusively.
I did just that, filled my parts bin with all the usual values in FM, and a few FC as many of the FC are shorter physically.36 Monitors, 3 TVs, 4 Laptops, 1 motherboard, 1 Printer, 1 iMac, 2 hard drive docks and one IP Phone repaired so far....Comment

Re: stocking capacitors,panny fm
Be careful with FC.
They are good caps but their ratings aren't up to what a lot of the caps used in screens are.
Choose replacement caps by the Ripple and ESR. <- Important.
FM are usually good enough for what is found in screens but there are times you'll need something with better specs or physically smaller.
FM run a little large for their uF in some sizes so to keep the Ripple and ESR where it should be you have to go to a smaller can in a better grade.
For example I'm working with one now where none of the caps can be taller than 20mm.
The otherwise appropriate FM are too tall.

Hi,
I have a serious problem to program the Z590 chipset SRAM with a Management Engine after replacing the chipset.
The new chipset is factory new and is not containing any Management Engine. Any attempts to program it into the chipset under Windows ends with a failure (eg. Error 20: Management Engine Device not present, or something similar).
Due to the lack of the ME several ports on the board, including all M.2 ports aren't working, booting OS works only on USB. So it's now other way, as to program the chipset with a ME.
Usually on ASUS boards it worked... -
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.
Rubycon YK DataSheet (b... -
I have here a HP pavilion hp 15-cs2975nd with a 1.095v power supply that is driven by a FDMF3035. I do see about 80mV of ripple on my scope. I searched through the datasheet to find possible values of the ripple but I don't understand the datasheet well enough.
So I have two questions:
1) what is the typical ripple voltages of gpu/cpu on a laptop or pc mobo?
2) what would be the max ripple of a FDMF3035 that drives an output of 1.095V?
Would be nice to have a rule of thumb of say a percentage of the supply voltage to be an acceptable ripple voltage....12-09-2022, 06:51 AM -
Hi
I have a Lenovo 530 14ikb i5 8th gen motherboard and it fails to start Windows: it normally dies after I try to load Windows. Getting into bios screen works fine.
Made some measurements and I suspect that there is to much ripple on the 2 Vcore coils.
What is normally the maximum ripple allowed on say any of the power supplies? A few %??
The ripple is on both Vcore as outlined in red in attached photos.
Could be a bad driver?
