Hi Guys, I was turning the power on and off on my original V2 Jynxbox Ultra HD, and then noticed next day, no power when I went to power it up. No sign of light at all. I removed the module and tried to power without module, no difference, the fuse looks OK, from what I can see, as it is so small, but it appears to have two metal lines across. Any thoughts, I have had this box probably 10 years, and I don't want to give up on it! Thanks
You're going to need a voltmeter of some sort to diagnose your problem.Assuming you DO have one, start by checking the output of the power supply.Go from there.
Just a quick update. I just took my compressor and lightly blew the internals with some air, and now it shows a red flashing light on the front. odd?
Where is the power supply exactly? I am not a circuit board guy at all.
The power supply is external on the Jynx:it's the black lump you plug into the back of it & into the wall.I'm willing to guess you don't have a meter handy then.Quote:

I do have continuity on the power supply, my electrical co-worker tested. The switch I got 0 ohms, to clarify. Not the red flashing light on flashes for a second, versus at one point it become continuous.
Don't check for resistance with the unit plugged in bro...you can damage the meter big time.Set your meter to a setting to test for 12volts dc current.Put the red lead in the center terminal of the output connector of the power supply.Put the black lead on the outside connection.Look for 12v or so with the power supply plugged in.That's step 1.Quote:

switch works, I think I must have bricked it, because I am getting a red light flashing quick then disappearing. Crazy part is, just got rid of all my old cables for loading files, I had them all, Jtag ones Rs-232. How can I do a factory flash, I forget, its been way to long.
anyway to do this without those rs-232 cables not USB, I cannot believe, literally last weekend, I got rid of every data cable I owned from all the Boxes I use to own, Pansat, Captive works, etc.
Didn't you know?The day after you throw something obsolete away you will need it desperately the following week.Quote:

Hopefully this will help someone else. I finally fixed my red light blue light problem. I tried to use the jynxbox loader but it didnt work me.
I can't put my finger on exactly what fixed my problem, but I will tell you the configuration that got me back up and running. I soldered a 10k resistor to pins 3 and 8 of the U7 chip. The pins are numbered as followed. Please take note to the marker denoting pin 1
o....1......8
......2......7
......3......6
......4......5
After failing miserably with the jynxbox loader I decided to try a different loader.
1. Search for STB EROM Upgrade 2.0.0c 2009-05-22. I found mine on some Zackyfiles site written in spanish. Make sure to change the port settings to the port number that device manager shows for your straight through cable in the com ports section.
2. I downloaded and renamed the JynxboxNA_factory_version_v8.bin to JynxboxNA_factory_version_v8.abs because this is the only file type that this loader would allow me to choose.
3. With the jynxbox powered on. Check include boot loader and hit next.
4. The next screen should say Synchronizing STBs...Please reset target. Hard power your jynxbox off and back on fairly quickly. "done" and the factory file started uploading and after accepting a couple of prompts my jynxbox came back to life.
I can't promise that the 10k resistor played a part in fixing it, so it might work without it.
Thanks, problem now, is red light is not flashing anymore, maybe I powered on/off tom many times in a row? Looks toast now?
odd 5 minutes later after messing with it for half hour, and re-positioning power supply wire, I now get back the flashing red light, very strange. I go from nothing, to a flashing red light, then that ended, and it would only flash red for a second and go away, then back to nothing, and now back to flashing red light after moving power supply, I kind of just curled it in the housing of the unit.
keegster17, what do you mean when you say switch works? Do you mean you replaced power supply or checked that it's working?
Is it the factory supply? If so go to Princess Auto and Replace it anyway SKU: 9012865 or order online. Once you have done that see it its still blinking. Reloading the box should not happen until it is booting. Is it hard to tell from your posts.
When I say switch i mean on/off switch. Factory supply, it seems fine.
Not sure where you live, but I'm more than willing to have a look at it if you're comfortable with sending it my way.I have some spare parts for Jynx on hand (power supply,remote,jb200,ect).I also have every conceivable rs232 cable known to mankind.P.M. me if you're interested.No money involved.
sounds like your power supply has an issue. look for fat barrel shaped capacitors. common problem with all units. power supply is where the main power wire from switch goes to the small board on left looking from top. unscrew board. have a good look for any fat caps,or broken solder points, if found cut the legs off.leaving points on board ,note numbers and stripe location on cap and replace with same value and stripe location. can be from other units as long as numbers match. switch works otherwise no lights at all. you can bypass switch by hooking the switch wires together, for now. don't mess with programing until after checking caps.maybe no need. All setops are forgiveable.
Here's a strange one. After reading this thread I decided to take out my jynxbox v16 that died over night about 10 months ago. No red or green light. I took out the jb200, plugged it in and started hitting the on/off switch, as keegster17 mentioned above, after 5 kor 6 flicks the red light in front started flashing. Every flick of the switch after that the red light got brighter until one flick the red light came on solid. Another couple of flicks and it booted up and worked perfectly. I unplugged it put the jb200 back in, and no red light again. I started flicking the switch again. After about 30 flicks of the switch it was working perfectly again. That was Saturday afternoon and it is still working perfectly . Thanks kingster17 for the idea.
I agree, the switch on mine quit some time ago, would not shut off. I just joined the connected switch wires and turned off by remote or front button,hard rebooted by power plug. I then removed the switch,cleaned the contacts with cleaner, operated for a while, checked with ohmmeter when solid, replaced and good to this day.Quote:
