Electronics REPAIR Klipsch Promedia 2.1 gaming speakers Fix Mosfets Capacitors

[@coburn_karma]

Mine lasted for 15 years, purchased at Micro Center for $109 back in 2002. RIP 2017. You have the knowledge, skills and patience to revive the best 2.1 speaker system of all time.

[@BobRooney290]

and now you can too. i've learned a ton from this video. thank you to the guy that made this video and saved countless people lots of money.

[@flyingfatcats517]

I'm going through mine today, very helpful video. As a EE for 30+ years, I'd hire you to be a tech any day if I were not retired. Your approach is dead on on just HOW to troubleshoot (T/S) a device. The rest on here should give all give a thumbs up. Good work. Best of luck to you.

[@horsey3206]

Super video! Just what I was looking for, but mine wasn't getting any sound to the little speakers. Love those 2.1 Klipsch

[@Waltkat]

Guess I've been lucky because the Promedia 4.1 speaker system I bought new many years ago is still going strong. Love the subwoofer and am always amazed at the amount of bottom end punch it can produce given it's small size. Just a side note for you the next time you're trouble shooting: the electronics in some active subwoofers use a white colored glue to secure some of the electronic components to the PC board to help keep them from vibrating and breaking solder joints. The problem is, this glue when it gets old turns brown and starts to become partially conductive. You can test for this using a sensitive ohm meter. As you can imagine this causes electrical mayhem with the electronics. Scrapping off the glue is a pain and time consuming. I've successfully used silicone glue and hot melt glue as a replacement in some repairs I've done.

[@mvanalst2003]

Great content. Thanks! I just picked up a set of these for $70 “open box” and want to keep them going for years. We’ll see how it goes! May need to bust out my Weller soldering iron, as needed.

[@makkgeo]

I had low subwoofer volume on my Promedia 2.1. Replaced 14 electrolytic capacitors on the LF amplifier board to the subwoofer and the power supply board. Resoldered any solder joints that looked cracked. Nearly all the old electrolytic capacitors tested high ESR, low capacitance or open circuit. After 15 years of being powered on 24/7 the caps dried out. The subwoofer works great again.

[@bradkaral1188]

Great video. You've covered so much in one place. Just a reminder, unless you're sure of the source, those MOSFETs sourced in China could easily be counterfeit....even if they don't sound too bad.

[@lethalz28]

You've got excellent skills, bro. Thank you for the video and clear explanation.

[@MrKittles1123]

Knowing zero about electronics, this video did not help me toward fixing the problem I am encountering (I have the pro media 2.1 bts and the sub works great but now both of the speakers are silent) but this was an AWESOME video nonetheless. Very fascinating watching someone who clearly understands the problem as well as how to go about testing and finding solutions. So I feel I still learned something. 👍🏼

[@toltec13]

I have my 1950's Eico 950 capacitor checker. I love the Eico 950 because I can put the capacitor under maximum electrical current load (1 volt--475 volts). It has a vacuum tube tuning eye, so if the eye opens quickly the cap is good; if the eye takes time to open the cap is so-so; if the eye doesn't open then the cap needs to be replaced. It has never failed me over the years.

[@brockobama257]

Back in the days before planned obsolescence! Anything I buy now just breaks and they make it damn near impossible to fix.

[@letthemusichealyou]

Got a fix for the thunder sound from subwoofer ? Thanks

[@KP11520]

I appreciate the how to on removing the LF amp board! Thank You! It might be a good idea to put a heat conductor paste between the Mosfet and Heat Sink, similar to what is used between a PC Processor and Processor Cooler. I really like that Hakko de-soldering pump! Keep up the good work! BTW, my original 2.1 has very low Bass volume output. Even at high volumes with both pots way up. But not distorted.

[@Desert-edDave]

Love the use of the MESR-100, I'm really wanting one of these.

[@bryanaustin8362]

Do you have a video for cleaning the volume pot if it's getting dirty? I need to do that.

[@Jayman001]

FREAKING BRILLIANT!

[@XLProductionz]

I just blew mines, no green light I need help I love these speakers and how they sound I definitely want to fix them.

[@inorite4553]

If you have the same version as his, with the power switch, check to see if you've blown the fuse. Its a 2amp, 240volt fuse

[@MisterTonyG]

How common is this problem? This Klipsch Promedia 2.1 set up caught my eye as my local Walmart is selling them for $89.99 new. However if this is a common issue, I'll avoid this specific set up. I know nothing is perfect but the Logitech Z323 2.1 set up I have now has had no problems and is 6 years old. It's fine for a $40 2.1 beginner setup, but I've really gotten into listening to music and want a better experience. I would rather have something that is very reliable at the cost of sound quality rather than the other way around. Any possible ideas or suggestions would be welcome. I'm a newb when it comes to the details of 2.1 audio set ups. I don't require massive bass power and would prefer a balanced set up. I mainly listen to rock/metal music by CD and sometimes by lossless digital files if I don't have the CD. Thank you.

[@greatvedas]

good work. I can imagine how glad you must be after fixing it. btw, where did you buy those replacement components?

[@rickdorsey72]

Mouser electronics stocks pretty much any part like that.

[@phamryder]

What's the inductor size for this model? Mines burnt out

[@BushXCGL]

My sub is cracking at really low frequencies, what might be the problem? Thank goodness I chanced upon this, but i'm still new to electronics so troubleshooting on my own would be hard. Shall attempt to try this out.

[@JesusPartida]

I have one of these systems but it’s an older model that does not have a power switch. After it got dropped, the system no longer powers on. Any idea what I should check? Thanks.

[@ChuckMoyes]

I replaced the plate amp entirely with a "TB20A TPA3116D2 Stereo Amplifier 2.1 Channel Class D Audio Amp" which has great specs for the value. It sounds MUCH better than the stock amp. Those stock electrolytics are garbage.

[@mikefisc9989]

Outstanding how to video. I learned something new.

[@adolforuiz3723]

hello friend, thanks for the video, it can be seen that you are an expert, I have the same equipment and I am concerned that it gets hot, let's say on a scale from 0min to 10max, a level 8.5. I use it to listen to music for 4 continuous hours once a week low to 60%, general volume 70% my question is why did yours break down? cordial greeting from CDMX

[@damianperez8524]

Mr. funbubble. Can you tell me how you ordered the resistances are 1k omh 1 / 2w 5% or how I ask for the measurement if you can tell me please.

[@shalbinjames]

Hi Bubble :) Great!! Keep Posting more, Thanks again!!

[@ironmannk]

i have one that just quit...amazon replaced no questions asked, what should i do with the old one

[@fearlessgentleman]

Hey Fun Bubble, Great vid. I have a problem with my set which i only paid $20 for. only one speaker channel has output. Any advice?

[@ronsqsavers]

Hey fun bubble do you work on other people's older Pro media gmx A-2.1 system. Ron T

[@thrty8street]

Do you have a link or a description of the capacitors and MOSFETs that you purchased?

[@jimvalim1567]

Where did you get the chart?

[@jimvalim1567]

Is that printed chart the same as the one on the mesr 100 meter?

[@Anthony-yf8nk]

You're a pro so is it safe if i put my volume from tablet to 100%? I just got these and kinda scared

[@jeffcotton526]

Those power supply caps are bulging on the top... did you replace those?

[@thiruu5096]

Hi, can you pls provide the 9 PIN DIN, Promedia 2.1 schematic diagram link?

[@jonasbrack1]

The right speaker not getting power, I tested my speaker with left port and works. Right Port not getting power. Any suggestions would be appreciated. Right Speaker works when tied to left side.

[@LucasLeCompteMusic]

Its more than likely your amp that has gone out. The speakers still work fine as you can see. It seems Klipsch makes really bad amps. My right speaker just out/isnt getting powered anymore and even if I use headphones, I have to pull down on the pod to get it to work on the right side. Someone on amazon actually bought a new amp and hooked all the speakers and sub up to it and they said they got everything to work. Currently looking into that myself

[@althiramakrishna2308]

Sir I am from india, my Klipsch speaker copper cone and coil also damaged can you arrange, please

[@jakegomez12]

Hi Sir, my klipsch 2.1 Pro Media suddenly no sound. First problem is no power, I changed the 2pcs open fuse T2.0A 250V, 2pcs shorted MOSFET FSA10N60A and open capacitor 100uf 50V now the power is ok but still no sound. any ideas please help....Thank you

[@inorite4553]

So question, did you have to completely remove that board to gain access to reflow the joints or did you just work around the other board?

[@FunBubble]

first time it broke i was able to resolder the resistor while board was in place. Second time it broke i had to remove to access components on back edge of board.

[@axchisler]

Is that a bit excessive for 4 caps to go out? What do you suppose would cause that?

[@FunBubble]

heat and age. they can cook and dry out

[@axchisler]

@@FunBubble Ahh yes, so do caps dry out in SS amps as much as they do in tube amps?

[@jafinch78]

Regardless of the application, albeit environment does appear to impact, parts have a lifecycle where some are more so known to than others. @@axchisler

[@traversalclan9688]

How do you fix satellite speakers where speakers are beginning to fray from the back of the unit

[@FunBubble]

if its just the wire itd probably be doable to cut and splice in a new piece of wire.

[@thrty8street]

My bass sounds really weak. Could this be the same cause of the issue?

[@brockobama257]

I should’ve studied EECS instead of Math-CS this stuff is so much more useful. I guess I could just learn. Do you have any recommendations how to self study EE? Moreover, I’m here because my right channel is quieter than my left channel. When right reads 1.0V left reads 4.2V. I figure there’s a bad (something) in there somewhere. I’ve taken AP Physics C and the college intro Physics Electromagnetism course. So I only know theory. I don’t know what a MOSFET is. I’m not sure what testing continuity is but I have a decent idea now. Here’s my second question. How do I know what each (something) is supposed to read? How do I know what a capacitor is supposed to read? Or a transistor, or a fuse? Does it say directly? I found a diagram online but it’s not identical to my pro media 2.1 so I feel like I’m guessing. This video was fantastic thank you.

[@thinknow1]

hello isn't it easier to get a cheap 200w amplifier 12V for less than 10 dollars

[@armandoramos1091]

i have promedia 2.0 and i yry to get schematic but didn't find one, can someone help me to find this schematic of promedia 2.0

[@MikeleKonstantyFiedorowiczIV]

much work for 100$ speakers. But satisfaction is worth it.

[@Lssjg702]

Is this something that happens often lol? I just bought some of those speakers.

[@3ltenoch]

Yes happen to me twice already

[@althiramakrishna2308]

Really u great sir

[@darylgarza645]

how much would it cost to fix the subwoofer if it doesn't turn on??

[@FunBubble]

if you paid someone else it'd probably be more than it would cost to buy a brand new system. klipsch is selling this 2.1 promedia set again. id at least try opening it up and do a visual inspection, you might see the problem.

[@ScorpTac]

I've got the same system, but only one speaker port works on the back... guess I'll have to pull it apart and buy new tools... 🤷‍♂️

[@fearlessgentleman]

did you get yours fixed? i have the same exact problem. i paid $20 for the set and i dont want to spend much more.

[@ScorpTac]

@@fearlessgentleman I have not yet

[@joshuawoodard6998]

The sound only comes from my subwoofer. Sometimes it will come in and then back out. Someone suggested that I need to replace a capacitator. I think I'll just buy a new one. I have no experience with electronics repair. 😒😒

[@daniel070487]

1:30 that pcb is toasted black O_O

[@curtiso.1751]

MY left speaker was cutting out for the longest time, now it just stopped working entirely. I only got these speakers i think last year, or maybe 2 years ago. I think you have the original version I have the new version with the built in engineering flaw.... There should be a class action lawsuit. I guess they lasted past the 2 year warranty period, barely. I can't live with just one speaker and the subwoofer. Apparently this is a very common problem I knew about it before I bought them, so shame on me...I should have trusted other peoples advice. Klipsch should get Asus to make their boards for them with high quality capacitors... Fuck what speakers am I going to buy now.. lol.. I could try to fix it, but I don't know if I really want to bother with it.

[@axchisler]

😶😶😶

[@multiHappyHacker]

Why do we keep buying garbage products that need repairs?

[@chrislee4485]

One of the most unreliable speakers. Mine broke for no good reason. Dun buy klipsch products ever again.

[@kkp4297]

suck'son capacitors are the worst.

[@tippsygammer4742]

Speakers are just BS
