Re: Se7500CW2 worth it?
Let me guess. It is HM(M) markings on these nichion caps?
Topcat sells Rubycon's here 2200uF 6.3v for 87 cent each if you buy 10. Samxon 2200uF 6.3v are 59 cents each if you buy 10.
Or you can buy from digikey.com and get Panasonic FM
http://search.digikey.com/scripts/Dk...name=P12344-ND
for 10, they are 46 cents each.
Any of these will work fine.--- begin sig file ---

Re: Se7500CW2 worth it?
wow your good!
and your right, they all have HM(M) markings...
For 10-15 bucks is worth it i suppose as long as i can justify power consuption with a use.
What about the rest of caps, physically, they look fine, but...you know....
Rubycon YXG 6.3v1000
Sanyo OSCON 820/4 (purple caps with no vents on top, that 4v820?)
Sanyo OSCON 270/16
Sanyo 25v100uf
PS21u 4v560 (silver color caps with blue color marking on top
Also has a burnt smd from the usb header, not to worried about that becasue my case wont even have front panel usb.Comment

Re: Se7500CW2 worth it?
My Compaq SFF has bad HM(M). That is how I knew.
Folks here like Rubycon and Sanyo. Don't know about the PS21u though.What about the rest of caps, physically, they look fine, but...you know....

And you are right about caps being bad without physical signs of distress. They could have high ESR (ohms) or out of tolerance capacitance. For example, a 1000uF 16V cap could measure 240uF.--- begin sig file ---

Hey all
I've been working on a 1984 Sanyo 27" color TV which had a smattering of bad caps in the video switching circuit. I found this oddball little 1uF 25V cap which looks to me like an early polymer, but I can't find concrete info proving it. I know Sanyo was a big player in early polymer cap development and this is the time period where they were just getting on the market, so I'm wondering if anyone has crusty old datasheets that could help identify it and determine if my suspicions are right? It has the same epoxy end seal and font/formatting as some old stock Os-Cons I've got laying...

Hey All,
I have a Sanyo DP5834 that did have an issue with the backlights, but I disassembled the unit and repaired the LED strips by resoldering all of the connectors. Now I've reassembled it and I have backlights and sound, but a grayish screen. I can tap on the screen and see that it's on, but no picture. All voltages seem to be correct on the power board.
Based on the LCD Flat panel TV troubleshooting guide by Bud Martin, I'm thinking the T-Con has failed because I'm getting 12v both into and out of FP1 on the T-Con. Am I on the right track?
Thanks,... -
Hi again guys.
Today I have a problem with this Sanyo VCR.
I bought it online, It worked sometimes.
I recap the Power supply and it started working fine.
Image is perfect and all digital effects too.
All of a sudden it stopped outputting sound. I checked for dried solders an all boards and soldered when needed, no fix.
I have no sound on playback, on tuner, or aux in.
On symptom I noticed is when it was working fine, the HI-FI led was on when I power up the VCR, now is OFF, A-B leds are on but when I put a tape they go off.
On one of the sound processing... -
Hi
I have a Samsung QE55Q65B with a seemingly common problem: it turn off and back on after a few seconds, (sometimes more, and in rare instances works for hours). D001 on the left side of the panel is very hot. I may be able to remove it with a very fine iron, but i don't have the equipment to re-solder such small parts.
Is there a risk to run the tv without this diodes diodes? And is it worth to pay someone else to replace it. I read many people who ended up with bad lines after trying to remove/replace them, , or the panel failing in another way, so i want to weight... -
What type of caps can I use to replace these Rubycon (K) caps? Can I use a film cap? I cant find any aluminum electrolytic caps that go that low. They are .033 uf and .047 uf
