Cyber-Pro cx1900 massage chair will no power on...

[Mike-D]

I need help diagnosing exactly what`s wrong , and how to repair at minimal cost .
So far all I have managed to do is blow the fuse .
I have power out of the fuse .

Mike, you need to be a bit more forthcoming with facts, sketches, close-up photos or anything else that will lend a clue to what's going on.

When does the fuse blow? When you plug it in? After you hit the power button? Is there a separate power switch or just the interface panel push button? Does it make a noise like a motor is trying to move before it blows?
Do you have a manual or schematic to work from? What were the symptoms before it quit working?

The background of the chair is I bought it two days ago and it didn't work when I bought it. I blew the fuse because I bumped across the post when I was checking for power coming out of the Transformer my hands not a steady that used to be. I have no information whatsoever. Just by looking at it I can see that when you turn the switch on at the bottom of the massage chair the remote should power up it does not. Now what I'd like to find out from someone is how to test a remote to see if it's bad and or two isolated at least to one of the boards underneath the chair. If it's the remote I like to purchase the remote one of the boards underneath and I would like for to purchase a board. The remote has a 4 prong Quick Connect. Now you know what I know. And thank you very much for your reply wasn't sure if anyone would reply because I can't find any information specifically on this make and model and I cannot find a serial number anywhere.
Thank you for replying and any help would be appreciate.

When you say "remote", does it look like this?

Is that the 4pin cable coming out of the bottom?
If you can take some clear close-up pics of the main board (front and back) that you were checking that would be very helpful.
If your lucky, It's a power supply problem ahead of the "remote". It may have some markings that tell you what the pin-out is either on the back of remote screen or the plug itself.
Again, a picture is worth a thousand words.

It can be deciphered without a print or manual, but it cab be an arduous journey by communicating on a forum like this.

It plugs in on the bottom of the left hand side by the power on / off / and the fuse is there also.
If or when I know the remote is good or bad I will remove the boards / it has two boards. Coming out of the Transformer there is a big winding screwed or bolted right beside the Transformer it has a black vented cover over the big winding I'm assuming the 24 volt is coming out of that and the rest of the system will be 24 volts far as I can tell. It's been a long time since I mess with ac voltage. I put the black lead on the ground wire on the frame of the chair measure the voltage coming out of the black and the white wires? On one side of the coil is located the Transformer are two white wires on that side on the other side of the big coil there arevtwo black wires coming out. If you could tell me what and where I'm supposed to have voltage and what amount. I am thinking that coming out of the transformer into the winding is 24 volts but I don't know what I'm supposed to be reading. Also I would like to add at this time that the pins in the quick connect on the remote lead are not numbered.

Ok, it's quite different than I imagined.

Unfortunately, due to the lack of info, the only way to determine if the remote is working is to first take it apart to figure out how the circuit works. You could just try to read if you have DC voltage on two of the pins but I don't recommend guessing.
We dont know what the voltage its supposed to be (12,18,24,30?)or the pin-out, and it may even cause damage to the com portion of the board.

If you can take some pics of those two boards and the internal guts I should be able tell you more.
If your lucky the board will be marked with the supply voltages and such.
I can't tell you where to check until I can see the circuit.

 

[Mike-D]

Well it appears that I can only load one picture at a time so I've got like 30 of them

 

[Tha fios agaibh]

Ok, great. One at a time is fine.

 

[Mike-D]

well let me know if you can see them or not . thanks

 

[Tha fios agaibh]

A wee bit out of focus but a great start.

I didn't know you were talking the remote apart already but that's ok.
My primary focus is the board where power comes in. A close up thats well lit to shows component details would be ideal. Even if you have to take quadrant pictures of each board. Just tell me what I'm looking at.

 

[Tha fios agaibh]

I believe this is where your DC power supply originates. Can you give a close-up well lit of this region? Where do those two wires next to the glass fuse go?
We'll need a photo of the traces on the other side of that region of the board also.
I'm guessing you've already checked this fuse?

 

[Tha fios agaibh]

I don't see any transformer.
Shown in the 10th pic of your last post is a vacuum air pump (on top) and solenoid values beneath it which directs the flow.

 

[Mike-D]

Thanks, I just wanted you to see everything .
I dug out an old camera , I hope this is what you need . and I have many more pics. so just let me know where to focus . thanks again ...

 

[Mike-D]

thanks...
I`m having problems loading the pics. I`ll send them when I can .
I`ll try later

 

[Mike-D]

Thanks...

Ok a bit dark but good so far. Can you identify where some of the cables originate?

What I like to do is open a photo in Microsoft paint and edit it to add writing to identify things. Or, just sketch out on paper .. eg;
120v power comes in the transformer, output of transformer goes to J4-1 and J4-2 (or whatever) so we can identify the plugs/wired connections on main board.

 

[Mike-D]

Oh! my back is killing me.

 

[Tha fios agaibh]

Much better pics. Where does the household power plug connect? 120v plug? I ask because the boards are European marked.

That white board is likely for filtering, but I don't know what feeds J2 and J4 (in). Does this come from secondary side of transformer, or does the main line power go there?

Hopefully you can get this fixed and give the old back a rest.

 

[Mike-D]

From the small block (pic. 3) goes in the transformer (white) out of the trans. are two red going to the big winding out of the big winding are two black going into J4 / also there are two white wires that go to j2 plug.
i have some electrical background mostly in the automotive field , DC... In the AC field is mostly pulling wires and component install on things like bookmobiles , crime seine units and such . i now i have power coming out of the big winding ( that`s where i blew the fuse . ) i replace the fuse and tested it again as DC . I believe it said 17v .i am unsure how to test AC voltage and don`t know what im suppose to have on each wire.
forgotten more than most people will ever know, getting old sucks ) thanks for your help . im ready to go towork on this thing

Show me the back of the bezel with the power switch and main fuse.
I need to know where the leads go from there. Yes, I see the two transformers one is either a step-up (or down) and the other is a toriadal type or an inductor use as a choke.
I'd hold off with measurements until we know what we're looking at here.
Let's focus on the path the the line power comes in and once we know that we can take some measurements.
