Dead unit?

[morty420]

I have had a Jyazbox (Jynxbox v21) for 3-4 months working great. I do not use the receiver too much (maybe 2-3 times month). I keep it powered off by using power switch on the back of the unit.

Today the box will not turn on. No power lights at all. I removed the JB200 hoping it may boot up but it did not. Still no lights at all and unit not powering up.

Is this a common problem? If so, what is the most common fix? I opened up the receiever but cannot visually see any problem (I am a total amature so I likely do not pocess skills to even visually identify the problem). Should I try buying a replacement power module?

One important thing... When the receiver was opened I had it UNPLUGGED from the wall (obviously!). When I touched something on the power module, there was a "snap" sound and a tiny spark(?). If the power supply wasnt dead before, mabye it is now?

EDIT: ONE MORE QUESTION: Anyone know if I can salvage a useable power supply from an old FTA box? I do have a few FTA box door stops (Viewsat 2000, CNX something, NFusion Phoenix). Are the power supplies in all the fta boxes compatible?

MORE INFO:

I found a thread on another site about using an alternate power supply. ANyone know if this will work with jynxbox v21?

Here is more detailed info about what I want to try:

My Jynxbox/Jyazbox v21 no longer powers on. I get no lights anywhere on the unit. I have tried removing the jb200 but that did not fix.

I found the sticky for "Alternative Power Supply for Jynxbox v2 v3" (this sticky is on another popular fta site, you could google the title and find the post easily)

QUESTION: Will these instructions work for my Jynxbox/Jyaxbox v21? I think my power supply might be dead but I am only a low skilled amature when it comes to electronics testing. I managed to get a reading with my multimeter at 2 different locations on the power supply module. One spot shows power (test point 1) and the other does not (test point 2). Does this mean my power module is dead? I also have a photo of an AC Adapter. Its output is listed at 12v 750ma. Could I use this power supply, and/or what would be the best output rating I should look for? I have a lot of extra ac adapters but this one has closest ma output as shown in sticky thread.

I am pretty sure my power module is dead in my Jynxbox. I do not have the knowledge to repair the power module, but I am sure I can put a new one in my jynxbox if I had one.

I searched (using google) for Jynxbox Power Supply and could only find one ebay listing from a person in Puerto Rico, but the item is no longer available.

Does anyone know where I can buy a power supply board for my Jynxbox v21? Thank you so much in advance for anyone giving me a lead.

You already have a thread on the go for this issue so I merged your new post into it. No need to keep starting a new thread for the same issue.

First of all I don't recommend anyone playing around with power supplys if they don't have sufficient training or at least a good understanding of what is going on. Although I am not employed in the industry, I took a 2 year electrical technology course in college back in the day.

It concerns me that you don't know that test point 1 is 115v AC which can kill you.

The old Jynxboxes usually had a 12v power supply. The new ones with V20 and up (which are probably clones) seem to use a 12v power supply too, although I have never measured this.

The power supply you want to use in the picture is 12v 750mA which is not adequate in my opinion. I have modified a few Jynxboxes for myself and friends and used a 2 amp power supply. A 2 amp will give you enough current for 2 fans and usually handle any diseqc switching issues.

You may have 2 problems, namely a bad power supply and a bad JB 200 module. I would pull the JB and get the power supply working first if it was me.

Again, if you don't know what your doing take it to a technician.

now for the obvious question... did you try plugging it into another outlet? or try plugging a lamp in where you have the jynx to see if the outlet is still powered?

He said he had power at test point 1.

I played with my jynxbox some more today and actually removed the power supply to visually inspect it up close. On the bottom side, I noticed a pin was not fully covered in solder. One of the thingy-things on the power module needed a bit more solder. I put a tiny bit on and it fixed my power supply! Yipee!!!

Good for you and sticking it out! I am glad you were able to fix your problem.

I too have a dead JB power supply. I haven't worked on it yet, but are you telling me it's judt 12 volts of current? I knoe the old boxes had an output of like 5V, 8V, 12V, 18,volt.

you would probably get a better response if you started your own thread for your issue
