I ordered replacement caps from.digikey but when.soldered on they overheated. The specifications were same as the ones being replaced. 470uf, 105 c , 35V.. the caps that came in looked a little thinner and taller than.original ones. So apparently something not right. The receiver I'm trying to repair is sonicview 360 e. The.caps are I'm.trying to replace are.responsible for providing power to the lnb and they are mounted on the power supply board. Any help in.identifying which caps to order.is greatly appreciated. No idea what the ripple.effect should be as there are many options. ):

re: gray 3-prong Ground adapter

That could still leave the guy behind the 'scope floating at 110v.
Not a situation I'd put a neophyte in.

The first rule of working on line-powered switchers, is to run it on a reliable isolation transformer.
As there might still be leakage, I use two robust 24v transformers, back to back.

I'm all for giving tricks to the newbies, but not if it might kill a stupid one.
And when it comes to strangers on a forum, ya just can't tell. ;)


edit:
I believe he shorted his rectifier in a previous post using his meter on a current scale to try and measure voltage.
Oh, you might be right!
And that makes my point! ;)

fhorta,
I have over 60 years involvement in electronics... And I have seen people injured AND KILLED. Anole is concerned about safety. The post advising to use an ungrounded non-isolated O-Scope is unacceptable! Differential inputs are designed for this very use. Ignorance and carelessness are Darwinian selectors. Say and do as you wish.

As pointed out, switching power supplies can supply over 700 volts -RAW- above chassis ground. If someone copied or used an off the shelf supply without designing it for the particular equipment, you could have a disaster. Did they use a portable defibrillator power supply in you STB? Three thousand volts? Un- explained blown caps? CAUTION.... ... ... ... ... or not. Your choice.

The main thing here is if he's not sure what needs to be done then check everything without power or find someone to help.

Now I will say that when working on computer mainframes and the drives we did remove the ground which was common practices for working on the equipment and that included all types of devices.

Anole,

You are definitely correct. I also use an isolation transformer, but failed to mention so. The iso transformer I have is a manufactured one that I got from work as salvage. I use the 3-prong to 2-prong adapter plug on its cord to ensure that earth ground isn't tied in there somewhere. I should have been more specific.

EDIT: May I add that I also did not expect Fhorta to rush right out and buy an O'scope for this task nor did I expect that he already owned one. Therefore the situation is moot other than the learning that was gained by all. I don't wish to withold information, but I don't want to sacrifice anyone's personal safety either. I know that you believe me in this regard, but I should have explained it in detail right off.

Sergei,

The video you posted is the best (safest) method. Rules out the earth ground/neutral leg connection and still provides the o'scope view of the signal where you can see, in real time, what is really happening with your circuit or across any load. Totally safe. It is a most excellent method to accomplish the troubleshooting that is required. I would still recommend the isolation Xfrmr and no earth ground in conjunction with the ADD/Invert mode on the scope and remove the ground clips from the leads/probes.

EDIT: I must add that these are the discussions which are most beneficial. Regardless of the negative comments that occurred, this thread has brought us to some very important information that is valuable to everyone and that is POSITIVE! It is occasions such as this which make me very proud to be among this group and be able to discuss troubleshooting practices in this way. I believe that we are here and this forum is here to educate and learn. I learned from this experience and I beliwve that other's did as well. Expressly FHorta. I hope that he has discovered his error and knows for the future what to look for and where to get answers. It's just a win-win situation when we all put our thoughts together and critique every item and discuss them all openly.

IMAG0664.jpgHello all. I do.apologize for flaming . I know there lots of members here with plenty of knowledge.and experience. Well, thanks to your help I was able to replace capacitors the right way this time, negative and positives sides how they should.be. caps are ok after receiver has been connected for well over an hour. Receiver powers up, goes on standby, channels, the whole nine, but still no signal or quality....again, any help is appreciated. I know I had posted that I might have damaged my rectifier in a previous post but being that receiver operates fine except for.signal and quality issues would that still be the case? Thanks again.

edit: added an image of the board i'm working with. the 3 caps i replaced are at top right hand corner .

I thought I would come here and find lots of complaints about the update to the dish anywhere mobile app, but am not seeing any. It used to look just like the desktop webpage. Now you can no longer filter by sports channels or movie channels. Plus that they made it look like a big button telephone and you see fewer channels in the screen which requires more scrolling. Yes I realize you can look at sports then select which sport you want to look at, I just liked being able to see all sporting events in the guide with all other channels being filtered out. Am I alone in the wilderness on this?

Anyone else watch this show? Any guesses as to what was in the box Gibbs gave to Abby that was on her desk? It look liked it was glowing.

I also heard that someone was leaving the show at the end of this season. Any guesses as to who thats going to be?

No. Bring in someone new.🤔 Tony is not serious enough for me. Parker is too close to the team and Tim is too young to take over IMO.

I don't think Tim and Tony are that far apart in Age ...

Remember what Tony said to Tim when they first got back together ...
Tony said: I am the New Tony, Tim .... (something to that effect)

Tony has changed, he's been running his Security Business ... I'm sure he has grown up.

Give it time ... your judging the New Tony from the old Tony.

It sounds like Tim won't be around the Team much longer either.

Might be worth a watch when it comes out. Looks like typical big corp against the little guy movie BUT....there is a reason this plot type is so oft repeated, it draws audiences.

If you're going try to read / listen to the book (can't recommend the audio book enough) before this comes out, I'd avoid trailers.

Trailer below, spoiling it to make sure you read the above bold message first. The book / audio book are fantastic. Go into this blind if you can IMO!




Kind of disappointed at how much they show. A lot still to see, but man, some good reveals in the book that are just served up here.

I agree. That can go for pretty much any book vs movie. Back when I was single I would read any Stephen King or John Grisham book I could get my hands on. When you read a book you make up the scenes and characters in your mind.....the movie version always disappoints.

A big win for the Patriots, and they are now 3-2.

Browns lose a close one with... The Jets. That is a classic Browns loss (granted, any loss is a classic one it seems). 49'ers, Vikings, and Chiefs remain undefeated. The AFC north have a three way tie at 3-2 for second place. :eek:

I had quit watching this show years ago because I ended up more annoyed than entertained. Well......I'm STILL more annoyed than entertained. I DO find it interesting to see how things work behind the scenes at many businesses. What annoys me is how utterly out of touch CEOs are with the companies they run. At the end of almost every episode the head of the company is amazed at how hard the employees have to work and many times have to work around impossible guidelines set forth from headquarters.

I found this one interesting because the new CEO had big plans for this company, Muscle Maker Grill, and it looked like the stores were all pretty busy. Recent history hasn't been good to this company however. I bet the covid lockdowns were the real killer.

Sometimes a thread gets so many posts in it that is can cause issues for the server so that why today we introduce The Song Name Game Part 3!

So let the game continue!

The last song was added by Bobby who posted...

One Meat Ball - Andrews Sisters

CONTINUE ON AND HAVE FUN! WELCOME HOME TO SATELLITEGUYS.US!

Here are the original rules for the game as posted by WebbyDude back in 2006. http://www.satelliteguys.us/threads/68645-Song-Name-Game

Just name a song title and the band who performed it. The next person does the same thing, but needs to list a song title or band name which includes a word from the previous entry. Pick songs from any genre.

Example:

Long Live Rock and Roll -- Rainbow

Rainbow in the Dark -- Dio

Another example:

Ride the Lightning -- Metallica

Lightning Strikes -- Ozzy Osbourne


Get it?


An additional note: we all know that song titles, sometimes, use profane words. Because this is a family friendly website it is advised that you clean up that title up a bit. This is accomplished by using something like sh!t instead of the real word. Thanks....
