JB200 repairs?

[keegster17]

any way to repair my defective JB200 module? I had my Jynxbox about a year, started loosing signal, someone mentioned get a new Jb200 tuner, so I got one, going to test shortly.
I was wondering if these are repairable? What burns out on them? In all the fta units I have bought, i never had to replace a part.

[bkr™]

I have never seen a schematic on these modules, but they seem to be 1 of the weak parts of the Jynxbox, and they burn out constantly.

[TurboPirate]

I saw in forums a photo of this module replacing 2 Caps with higher volts ad uf. Turbo

[keegster17]

You would think someone can pin point the burn out point and repair?

[Newfygarge]

Would be nice. Im looking at 1 & I don't see anything wrong with any of the caps. Would be nice to see this for all the modules out there.

[frostycold]

The units are 24 bucks. Probably not worth the repair and time. With the Jynx, you should always have an extra JB unit ready to go.

[Newfygarge]

Yes but another $20 for shipping. In my case.

What probably goes bad in the JB 200 module is the surface mount IC under the heat sink. Good luck removing it and better luck finding a replacement.

This is the photo I was talking about, it was in a Spanish Forum, found it and here it is..........

Tantalum caps. Hmmm. Had ro replace some of those on a wiz 110sr board.

I also recall replacing some caps in Pansat 2700 power supply..,....I am sure it can be easy for some one without shaky hands lol I can't do that job anymore

[iq180]

On ebay there is a pack of 50 caps for less than 7 usd with free shipping and they are in the U.S.

[keegster17]

how do you remove the old ones? I would be willing to give it a shot if someone explained.

[poppy]

There is five small screws around the back and sides of the receiver,take them out,then take off the small bolt nut on the jb200 lift the top off and pull the jb200 out of the slots and replace with a new one if thats what you are trying to do.

[iq180]

You need to unsolder the old CAPs and solder in the new ones, they are very small like one grain of rice small, you will need
to know what end is + and what end is -, but I will say this, if you need to ask this ???? I don't think it will end well for you,JMO.

[TurboPirate]

Just like Iq said you need a soldering tool looks like a pencil they are electric and butane. I got the butane because most of the times I got to do some soldering where I got good light to see what I'm doing there ia no electricity so the butane is the right tool in my casa.......but if it is a too little thing like the caps of this module someone else has to do the job because of my none stop shaky hands...,.trust me it is good to challenge your self to try but you need to practice applying the proper amount of soldering stuff or you'll connect one circuit with another one making a short circuit.

[bkr™]

It is very tricky, and very little heat is required to de-solder components . Had luck doing JB200 to JB200-B conversion w/ many modules, but destroyed some also. A pair of precision tweezers is necessary, not what your wife may use to pluck hairs. Not sure these caps are the problem, but also willing to try to see if swapping out fixes problem.

u dont need those caps u need to buy 22uf np non polarization caps it work on my 2 brocken jb200

[bkr™]

Finally received my caps...unfortunately they are 2X too large in size to work for the area available, oh well was worth a shot anyway.

[edrik]

would you have a link to the caps you ordered? i see in the thread that the wrong ones were accidentally ordered.

a photo of the caps you ordered I might give you an idea but need to see what you ordered. TurboPirate

You can still use the caps if they are 22uf, all you need is 2 small copper wires soldered to each end of the cap, then bend the wire
over to match the solder points on the module then solder them to it, I do this all the time in auto repair, TV repair & computer
repair.

[lolipop]

use heat gun to remove cap. Search on flae bay

[iq180]

I think the heat gun is a bad idea in this case as it will melt the solder on the other parts of the board,JMO.
You don't even need to remove the ends of the old caps most of the time, all you need to do is remove everything between the
ends of the old cap then solder the new cap on top of the old cap ends.

[lolipop]

Any update about success or fail ???

It looks like no news is not good news.... at least in this case.

[bkr™]

I have been trying to provide the photos in this post as an attachment, however either this post is not allowing me to attach, or I am doing something different than I have done in 100's of other posts, as you can see by my previous deleted posts in this thread.

[Newfygarge]

This thread was a great help today. Turned on my jynx v6 less than 2hrs ago & no power. Did a search here on jb200 repair & found this thread. Looked at the picture on page 1 post #9 & replaced the 2 caps as shown in the picture. I put negative pointing towards back of receiver. Also put in a bigger fan. Great to have things lying around the house. Oh,the jynx is working perfectly now.

[keegster17]

Has anyone tried anything new on this post? Some new pics would be great if so. I want to try this, I have now 4 of these modules, it is worth a shot. can someone supply specifics as to what i need?

[keegster17]

I did buy the Diodes, de-solder pump, solder, solder pencil. but curious how to remove old in detail, and how to connect new ones. One post mentions putting negative side to the backside of unit. I didn't thing a diode was made up of negative and positive but more direction.

[TurboPirate]

What that means is the proper direction, diodes are designed to allow current go one direction not back..............

[jvvh5897]

putting negative side to the backside of unit
That was for the capacitors. Both caps and diodes are marked as for what part is what--I would think a quick search would find you lots on the topic.

[fightdoc]

I just replaced mine. easy to swap it out.

[jvvh5897]

Yes, easy to swap out and cheap, but it would be nice to see some actual testing done on some of the boards (and some of these newer boxes). Who know what might be possible if you just figure out things like pin-outs and find data sheets? For instance, you might be able to get the Broadcom chip on the tuner to do directv type signals. You might find out a setting that does not create as much heat.

[keegster17]

fightdoc, any chance to provide some detail on how you went about the procedure?

[keegster17]

I have managed to remove C52 and C55, So how do i know how to solder the new diode on correct?

[jvvh5897]

Well, if you are trying to replace two capacitors with a diode, then I would say that there is NO WAY to do it correctly.

[pisici]

I HAVE 2 module broken
One module working only in SD signal
How can i repaire this ?
thanks

[ricferr1]

Hi have the same problem !!

[keegster17]

regarding my post #37 I meant to say Capacitors. I bought 22UF 100v, NP, as another forum mentioned with the (NP) non polarized capacitor it doesn't matter which which way they get soldered on. I thought I did a ok job, but no luck. I may try another board.

Old thread I know , but mine just went out today, (end of may 2019) here's some pointers .

This is common in FTA box tuners and modules with broadcom 8psk turbo chip, oddly it only happens on fta units orig and clone.

When you get the qpsk (sd) channels with good signal, but a low 20-40 signal on 8psk, only the 8psk part is dead, usually from overheating. I've had it happen a few times on ilink, and jynxbox.

Occasionally or if you catch it in time, ie seeing weird issues like sudden signal drop or picture issues , turn box off measure with a laser heat sensor , you will find it's way too hot ( broadcom chip ) .

I put a PC case fan blowing air onto my tuner dropped the heat from 120 C to 30 C (yes there is the silver heatsink) in 2013.

The smaller clones have a tiny 386 cpu fan preinstalled v22-v30 facing the tuner, which seems to work too and fits easily inside the case .

I prefer v1-v3 jynx as they have all the orig i/o features, IR extender, too!

So How did mine blow today? Well my v3 bootlooped a year ago, from trying to load a factory channel list. (Current 2014 list is inaccurate lol)

I found a V2 orig on CL bought that, put V3 in closet, the V2 seemed to work so well, that I never bothered taking the lid off. Software was already on there V1.239.

Didn't bother putting in a fan or anything.

Today Worked for a few minutes, crapped out I went to non 8psk still working, then back to 8psk signal was 40 and only qpsk worked at 85% signal,

Using another receiver , confirmed signal wireing etc working , then I opened the v2 it was pristine, my old v3 tuner was filthy (see pix, its now in clean machine )as I had fan blowing air on it.

That got me back up, but now I still have a "crippled" jb200

I used a multimeter as suggested here to test the caps and the diodes that are beside them. Caps had voltage and did not have continuity, (no beep)

Depending on which meter some showed caps at 22 or 23 the other meter showed 11

My next step is to check the esr of the caps.

I'm not sure why the different results (different digital auto ranging boot meters)

As to the diodes one in the middle of the 3 is covering it's pad towards the rear of card .

These are very poorly made.

I've had original ird with same broadcom chip no issues, I've had genpix with same chip no issues , no fan needed in both cases .

My friend has also had 3 jb200 go and a ilink go.

I'll try esr meter when I find it. Maybe the heat caused a drop the electrolytic medium? But as I did one is 23uf.

If your here it's too late , but don't use your fixed one without a fan, my v3 was a clone , I felt that the v2 with orig tuner would be better, it was , but failed a year later .

Ps: while both tuners look the same with slight differences they both say v2. You can see the one with writhing above the tuner can, the other one that says 2012 near the caps also say a qpsk v2 above the tuner can it a hard to see.

Could anyone tell me what thier caps said when in circuit or if they show a short?

[Willucome2014]

Check out my pics two of my diodes face one way one the other.

You should be able to cool the unit down even more by flipping the fan over sucking the hot air out of the box instead of blowing cool air into it.

[Willucome2014]

That's what I did this time, have it sucking air out, my cutting of the top276467 of lid was not precise though , as I used garden primers, can't find the right stuff when I need it lol. powered the fan with the 12V and gnd off the second tuner slot, multimeter temp probe says its 21C inside , (slip the probe from gap left in crappy cutting job) but now it's slow and flaky making it's "ip" connection I know its not service supplier because a second jynxbox v30 works flawlessly.

Sucking not blowing, Don't want to sandblast with micro dust since these are $40 US plus shipping now.

[Willucome2014]

I noticed new ones for sale have a blue PCB and a silkscreened date of 2017 , does anyone believe they're any better than these 2012 ones ?

Everything seems in the same location.

I did notice on a Latin tech guy's fb page he repaires these and installs fan, internaly underside of lid,

His green pcb jb200 had a wire running from satellite input area on back of tuner, between 2 tiny pcb which were populated with the 3 legged power things and some capacitors.

Anyone heard of this repair? Is he just beefing up what the China factory skimped on?276472764827649

There has to obviously be a reason for this

Quick update, Replacement Tuner issue resolved by pics , with fan, it's about a 3.5 inch fan , anyone else using the 2nd tuner slot, word of caution get a multimeter and check all inputs, some measures over 100V, the obk8be pics mention the 5v slot, but my fans are larger and 12V, there are both voltages and others there, be careful, pic the right ones.

The other issue was entirely a "connectivity" issue lol

All that said my original jb200 is sitting on a shelf it still has the gets qpsk modulation at 85% signal but 8psk at 39% for jb200 the dropout threshold at 62% fyi . I tested the caps and diodes mentioned here all are ok,

Any ideas?

What's the Latin guy in the pics doing? Adding more power to voltage output?

This has to be a fixable issue.

I very much doubt the broadcom dies of heat. It's same chip in provider boxes, since the 1st HD one.

[Jdread]

When tested with the ESR meter what reading did you get? I am getting a reading of 19uF is this good or bad. My box is rebooting after working for a few minutes. I have dis-connect my sats from the box and it is still happening so the problem is not switch or cable. When I take the tuner out the box stops re-booting so it must be the tuner. I have tried the tuner in both slots with the same problem. I was always running with a fun and therefore no heat issues. I am willing to try anything to solve this problem.

[Jdread]

OK guys up and running again, changed out the two caps and used the 22uf 25volts electrolytic caps to replace them and my box is up and running without any issue. Never read any where that this could be done using the electrolytic capacitors instead of the ceramic surface mount ones so I want to let everyone know that this can be done. When I take out the caps they were reading 11uf so I knew right away they were the problem.
