Re: 2 no-POST Tyan Tsunami S1846 motherboards
Both fixed, plus a third (my sister's):
1st-used 5 Nichicon HM 10x16mm 1000uF 16V
2nd-used 5 UCC KZN 10x16mm 1000uF 16V
3rd-used my last 4 UCC KZN 10x16mm 1000uF 16V & last Nichicon HM 10x16mm 1000uF 16V
I didn't use my 10V HMs because either I've grossly misplaced them, or my inventory is wrong.
Sis's ancient Antec PS had 3 leaking 10x30mm 2200uF 6.3V Jenpos. I used 10x25 Panasonic FR for those, closest I could come from stock that could fit the tightly crowded space.Leave a comment:

Re: 2 no-POST Tyan Tsunami S1846 motherboards
Neither board will POST with any combination of cables connected, with no cables connected, or with all needed ones connected.
Blinking cursor top left IME can happen from either no boot device, or corrupt boot sector, or POST never occurring. The last is the case with these.Leave a comment:

2 no-POST Tyan Tsunami S1846 motherboards
I have twin [URL="https://web.archive.org/web/20000817085308/http://www.tyan.com/products/html/tsunamiatx_p.html"]S1846[/URL] boards that won't any longer POST, and Slot1 Coppermine 700MHz and Katmai 600MHz to fit them. A slocket with 933 Coppermine won't POST either, No beeps. The graphics card does put a cursor on the display on power-up. Mixing the parts up doesn't change anything. Three different PSUs, and other RAM sticks don't help either. If there's anything on the web about S1846s routinely dying of old age, I've yet to find it.

Re: TR2 Thermaltake W0070RU XP550 NP - worth recapping?
Thanks for the responses!
Fatigue negatively impacted my search fu. This, that I should have found searching for squeal or Thermaltake, is exactly the one.
Unfortunately, my zeal to find the source of the squeal before seeing ChaosLegionnaire's reply killed it. I had taken the board loose from the case to get my improvised stethoscope in position to to listen to the bottom side after not having luck isolating the sound from the top side. The cables decided to spontaneously shift everything, the...Leave a comment:

I neglected to refresh before replying to myself, so missed Per's response. I'll save this as is, since I only get 90 minutes to edit, then pursue his valuable leads before returning after a fresh page load.

TR2 Thermaltake W0070RU XP550 NP - worth recapping?
Only two search hits here, one casually mentioning lower/middle calibre many many moons ago, not terribly helpful, and the other, simply exposure to it, and neither included the RU suffix. Is this a design worth recapping to keep a 10-15 year old PC operational?
I replaced the obviously bad Ltec LZP 2200uF 16V and the obviously bad pair of CapXon GS 18x40 620uF 200V with Nichicon 22x50 UPT. It lights up my digital PS tester with suitable voltages, but it emits a screechy squeal that just drowns out the two 80mm fans. It probably would only very slightly annoy installed in a PC in... -
Re: Replace OST RLP and Nich HM with what?
Its PS is an [b]Antec[/b] EA-430. I already replaced its OSTs with (mostly) Nichicons years ago. The CPU is 65W TDP. 3 500G Seagates as of a few months ago, was 1 for past several years until a few months ago, originally 2 320G when it was my LAN server. Passively cooled Radeon video. So this is not a power hungry configuration, and it doesn't get used enough to justify throwing much money at it.Re: Replace OST RLP and Nich HM with what?

Re: Replace OST RLP and Nich HM with what?
Those three ads all stated an estimated delivery time "X" days. The shortest X was 35. I've ordered from overseas before. Wait time has been highly variable, from under a week, to much more than a month. Orders from Mouser using lowest cost shipping arrive in as little as 3 days.Last edited by mrmazda; 02-10-2019, 09:06 PM.Leave a comment:

Replace OST RLP and Nich HM with what?
Apparently 1000uF 6.3v is being obsoleted off the planet. Those I need to replace are 8X11.5x3.5 from various motherboards, mainly near DDR2 ram slots and northbridges. If in fact they are being obsoleted, there must be some polys suitable for sustitution, but what? 8X15 or 8x16 lytics can still be had, but troublesome to fit in various spots, similar to 10mm.
Some years back, the [URL="http://www.foxconnchannel.com/ProductDetail.aspx?T=Motherboard&U=en-us0000297&Language=en-us"]board currently in need of resurrection[/URL] had the same problem as just returned... -
Dell 2405fpw flickered 2 weeks ago. Replaced non-leaking Elites on PS bd. No joy after replacing them & 4 Lelons. Watched of [url]https://www.youtube.com/watch?v=rQwCqatbLr4[/url] (good edu re dealing w/ surface mnts, so TKS). Voltage @120uF 450V CapXon KM only 163V. F702 0 voltage. Couldn't make out where you were testing for 18V, but F701 also has 0 volts.
No obvious burning anywhere on either PS board or logic board. Logic board does have 220uF 35V Jamicon TKs, but no obvious leakers. Any ideas/suggestions (besides replacing CapXon, which I should have done but didn't because... -

Re: List of Bad Cap Manufacturers
I opened up my #1 Magnavox MDR513H DVR, my only Magnavox MDR515H DVR, and my #2 Magnavox H2160MW9A DVR to find Su'scons in place of the three bad Enercon GS 3300uF 6.3V 85° I recently reported here. These machines all have 8x12 Enercon GS 1000uF 6.3V 85° at up to 6 visible locations each, including one on each PS board. On the MDR515H the one at C1419 on the mainboard has a swollen top.Leave a comment:

Re: List of Bad Cap Manufacturers
When I searched Mouser and Digi-Key for equivalents to the bad Enercons I found all 5 major brand (Mouser) results in the 10x20 can size spec'd to materially lower ripple, were 85° rated, and classified as GP. (Digi-Key) results with at least as much ripple were all 105° and at least 25mm tall (but also classified as GP rather than either low impedance or low ESR, which it seems Digi-Key does with all 'lytics). So it seems Enercon must be publishing optimistic specs.
So you started back when popular consumer electronics...Leave a comment:

Every cap I can see in the machine is 85°. I have other machines in the model series, older and newer. I opened up an older one to find Su'scon in the PS board locations of the one with bad Enercons, as well as most other locations, but 8x12 or smaller Enercons in two other locations on the PS board, and several locations on the main board. Funai is the actual manufacturer of the Magnavox-branded machines....Leave a comment:

Re: List of Bad Cap Manufacturers
Does Enercon belong here? Using both the menu and Google to search for it here turned up nothing good or bad. My #2 Magnavox MDR513H DVR quit. I found 3 heavily swollen Enercon GS 10x20 3300uF 6.3V 85° caps on its PS board. Replacing them with on-hand 10x25 Panasonic FR fixed it right up.Leave a comment:

Re: Lenovo ThinkVision L2440pwC stays black
When I found this thread I thought my Lenovo ThinkVision L2440pwC was candidate for a solution as I read Teredactle's comment. It worked fine from the time I bought it until I had to move it upstairs to protect it from Hurricane Hermine water coming in the house. After the move, sometimes it would produce output from a PC, other times not. I broke it down looking for what Neon found, but saw no evidence of burning or overheating. I put it back together without changing anything more than contaminating an output layer spraying contact cleaner...Leave a comment:

Sony STR-KS2300 5.1 channel A/V receiver circa 2007
This belongs to my best friend. He came home one day after a heavy thunderstorm and it wouldn't turn on. Eventually I took the cover off, then removed the PS board for close examination. I found no sign of any burning, so examined all caps. There are many, at least 50, all white letters on black, and all Rubycon or Nichicon except two little Jamicon SKs, a 22uF 35V and a 100uF 16V. I removed the two suspects. ESR showing on my ESR60 for the 100 was about 1.6, so I put in an FR to replace it. For the 22 the ESR60 reported "open circuit or low capacitance". I found no brand name match... -
Re: Dell SFF PSU's OSTs
Part # HP-L161NF3P
I got ambitious and discovered my first invisibly worthless OST, an RLP, C401 1000uF 10v. Two more Teapos were also shot, SC C408 1000uF 16v, and SEK C801 220uF 35v. In all I replaced 11 caps 220uF and up, all RLP or Teapo. Two I had no direct equivalents to. I replaced C409 2200uF 16v 10mmX30mm with a used 85° Nich VR 3300uF 16v 12.5mmX25mm, and C801 220uF 35v 8mmX12mm with a used Lelon RGA 220uF 25v 8mmX11.5mm.
