i found a how to, more or less on repairing power supply. i'm trying to order several electrolytic capacitors to replace on power supply board. the reason i'm doing this is because receiver does not get signal or quality. the premise at this point is that there is no lnb power being provided to the tuners. this requires the replacement of certain capacitors but is recommended to replace all capacitors wihin that given circuit to avoid further issues. anyway, just mentioning this in case someone is on the same boat.

my question: by ordering off of digi key website, it asks to filter for capacitors by providing desired uf, V and temperature. the caps i'm trying to replace on the board are two 470uf/35V, and one 220uf/35/V and they all have the 105 temperature written on the caps. I can find right capacitor by uf, v, and working temperature. for example, my plan is to replace caps EC 201, EC 210, and EC 202 on the power supply board. where i'm lost is what ripple effect, and lifetime should i choose? there are some capacitors that work at 105 degrees for example but have diffeerent lifetime hours such as 000 hours, 2000, 3000, 5000 hours at a given working or lifetime tempeature? anyway, kind of lost on this so if any one can help..also when filtering for the right capacitor it asks for the series. i'm not sure what to put there either. also, the capacitors on sv are samxon; will it make a difference if i replace them with other brand such as nichicon? there is no samxon brand offered by digi key. thanks again.​

Thanks for.responses. as.far as.smoking the power board, I realized it wasn't the power board I was testing, but another component in.the mainboard. I plugged it back in and.everything.worked fine except.the previous issue of.no quality and signal. At this point.I.could.throw.away.receiver and purchase another for over $150 or.I.can spend $5 and.see if.works. I borrowed soldering.tool.and soldering.removal. thanks again. Btw, I had.receiver checked twice (free) and both repair techs said it was the power supply board. Of. Course they didnt say what part of the board specifically but I was happy they found nothing wrong.with mainboard. Which is where tiny speck of smoke came.from.

My first guess for the smoke would be a resistor , so I'd start looking at them. Also the best way to remove components would be to cut them off on top the board and then use the iron to heat the remaining lead and remove it from the bottom, this way you'll have less change to damage the circuit path by using to much heat. Then you can use a desoldering tool to clean out the hole.

I am a maintenance man/electrician and I repaired many power supplies where I work, I must say that I am not a electronic guy.
What I do when replacing a capacitor I get a capacitor with an higher volt value. In your case I would get a 50V capacitor even though you have a 35 V capacitor in it. The uF have to be exactly the same. Most online sites should give you measurements on capacitors, this way you can make sure that you have space to put them in place.
Since most of those capacitors are DC capacitors you have to put them in place the same way.... minus to -, so mark them when you take them out. If you solder them in backwards you will damage other components on the board.
Many times when a capacitor goes bad the ends bulge out or ends are rounded, I even seen them raise up and grow taller.
It is a possibility that the voltage regulator or other things are bad on the supply.
You can call digikey and they are willing to help you.

Did you check the output voltages on the power supply ?
Did you google for a replacement power supply ?

This is good advice, to use the same capacity (microfarads) and higher voltage. But usually such a capacitor is bigger (taller). I fixed a faulty (pixellating) Viewsat receiver, replacing a few bulging capacitors with bigger ones, extending their terminals and placing them horizontally, above other elements. So far, the receiver works OK. Cheers, polgyver

I have the same boxes and they are not that bad but instead of fixing the receiver why don't you just get a high def like the micro hd or an openbox?

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?

I'm not a big fan of the new layout, especially on my Apple TV. It used to look like the old Guide layout on the Hopper 3, but they changed parts of that, too.

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.

Forgot to comment. I did watch when it first came out on MGM. I enjoyed it a lot. I think reading the book made it easier to watch. Several friends commented it was a little hard to follow.

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.
