Extron Emotia (Original) - ATTN OWNERS - Need Repair Help

Post by philexile »

Hello,

I have an Extron Emotia, the original version. I'm including an image below for reference.

Image

I noticed the output picture was very off, practically blown out with brightness sometimes, other times, gray and muted. I opened the unit up and saw that right in the center of the board there is a ceramic disc capacitor, slightly smaller than a dime in diameter, cracked down the center. Its next to a small tube capacitor and between two chips labeled "Bt." It appears to have been coated in a blue plastic at one point as this coating is visible at its base. Maybe when it cracked the protective coating came off? Below is a picture I took with my iPhone. You can see the cap in the center:

Image

I've been in contact with Extron and, while they've been very helpful, they no longer have sufficient documentation on what replacement capacitor I would need to make the repair.

I'd like to ask that if anyone has this Emotia model, to please open it up, locate the part in question, and let me know what the markings/information is on the capacitor. This would be extremely helpful for me to get a replacement. Since the coating is gone on the cap, so is the info I need to get the right part.

These units are very easy to open. You just remove four screws on the sides and lift up the lid, being careful not to pull on any of the RGBs cables in the back. I'm including two additional pictures below that have the ceramic disc capacitor circled.

Image

Image

I would greatly appreciate any suggestions on this matter.

Thank you in advance.

I have this model, and I have a different problem (NTSC mode is screwed), so I'll open it up and see it I can get that cap value for you.

Hello,

I have an update. As I made this post, I also emailed a seller on eBay who had the same Emotia unit up for auction. They were kind enough to open it and photograph the component in question for me. These three images are included below.

Image

You'll notice that there is no information listed on it and, after looking at these images, I wonder if this is even a ceramic cap at all.

Does anyone here have any suggestions as to what this is? Is it a ceramic cap or something else entirely?

Thanks again,
Phil

I have an extron super emotia that exhibits the same problem you're describing. Would love to get it operating at 100%. will follow this thread with interest. sorry i can't be of help describing what that is...

Can you take some pictures of your screen output? Also, what are you pushing through it? Dreamcast, Xbox, PC?

Hi Antron,

Were you able to check out your Emotia? I'm curious if yours has any values written on it. I noticed that the models vary a bit sometimes, so yours may still have the info I'm looking for.

Also, I was in contact with an Engineer at Extron and he is fairly certain this is either a capacitor or a heat sink.

Does anyone else have any thoughts on this?

No not yet, I wan't sure you wanted me to since you had a picture. I'll try to today. Thats definitely not a heat sink.

In your picture from above it looks like a broken plastic disc.

Thanks!

I don't think its plastic. Its maybe ceramic or metal. The engineer was at a loss. He said its also possible its some weird part other than a cap.

This was using an Xbox (not 360). I've pretty much moth-balled it since, so it will depend on what sort of free time I can find. No promises, but I'll try to hook it up again in the future and snap some pics. Hopefully DOA Volleyball won't offend anyone...

Hey,

No problem. Thank you for checking it out.

Anyone else have one of these units? Any engineer types that may be able to decipher what the part is?

Thanks in advance.

Ok, let me know. If we both have the same issue and this is due to capacitor failure, they are easy enough to fix.

I have this unit (unfortunately mine does not work either, I get no video output from the unit), so I took the case off and found the component you mentioned:
Image

Looks like a PTC C945 thermistor. Don't seem to be widely available based on my searching, but it could be a starting point.

It is a starting point, thank you!

I'm in contact with Extron, so I'll be sure to send this off to them. Its possible they will be able to recommend a seller or an alternative replacement.

What happened to you unit?

I think I screwed up the power connection and fried something. It worked when I got it, and I decided to replace the connector for the power supply (I'm using a PC power supply wired to the 5-pin connector since I lack the one it originally came with) . I think I mistakenly sent a voltage to ground that shouldn't have been. What happens now is that I get a blank output from the unit on all video outputs. I can still see whether I have it on interlaced or non-interlaced, but the screen is totally black, and I have checked the resolution of my inputs and such. I have a Super Emotia that works with the same power connector, but for some reason, the non-interlaced mode does nothing but dim the screen.

Have you tried outputting through VGA? I heard that sometimes that works when the other outputs (SVid, RGBs, Composite) do not. If it does work, you could then convert the VGA signal to whatever you need.

I spoke to Extron regarding the photo of the part and he wanted to see if you could either post a clearer picture or let us know what the exact numbers are on the component. He said it looks like a positive temperature coefficient, but needs to be sure of the numbers, both the one "C945" and whatever is smaller directly underneath that. Also, is there anything printed on the other side? All of this will help in narrowing down a replacement.

Thanks again for your help!

Outputting through VGA wouldn't really help since it's a VGA signal I want to convert in the first place, would it?

Anyways, I'll get some more pics for you when I get back from work.

Oh, yes, well, I guess. The reason I use these Emotias is to force 240p from a 480p source.

Looking forward to getting the photos/info

Thanks again!

Hmm...couldn't really get any better pics, lighting in my house is horrible. But anyways, the numbers on the side of the component read like this:

PTC
C945
-------------
9522

The other side is blank.

philexile,

The component is called a Polyswitch, at least around here. Just a self resetting fuse, basically.
http://www.jaycar.com.au/images_uploaded/polyswit.pdf

Here's the datasheet for your part
http://www.epcos.com/inf/55/db/ptc_06/O ... 599__5.pdf
It's rated for 1.3A sustained current, 2.6A trip current.

Thank you!

Extron just sent me the same data sheet.

Thanks again to everybody for help. I'll be sure to post before/after pictures if I'm successful. If I'm not, I'll post that as well. :)

After reading the datasheet and about the fuction of a PTC, I wonder if the Emotia is already permanetly damaged. Any thoughts on that?

Thanks

It's fairly likely that the root of the problem lies somewhere else. Try replacing the the PTC with a 2A fuse and see what happens. Though it's strange to see one of these devices is this kind of equipment, the're usually used where and overload is a more common occurance, like in a stereo speaker for example.

If it is just a fancy kind of fuse, my first thoughs are to check the tag tantalum capacitors littered around the board...

I think I'll be able to track down the appropriate PTC. Are you suggesting the 2A fuse because the PTC has failed previously? Could you recommend a particular part # as well?
viletim wrote: If it is just a fancy kind of fuse, my first thoughs are to check the tag tantalum capacitors littered around the board...
The tag tantalum capacitors are the smaller tan ones right, not the larger blue tube-like ones?

Sorry for all the questions, I'm not as versed in electronics as I'd like to be.

Thanks again for the help and advice.

Update:

DigiKey sells this part for cheap, under $1.50. Unfortunately, you have to order 1000. :shock:

Checking with my girlfriend's brother-in-law, who lives in Germany (the home of EPCOS) to see if he can get me a few.

Moderate success.

The image is now stabilized, however, the picture is still too bright. I notice that its (almost) exactly as bright as my Super Emotia is when its "Monitor Termination Switch" is set to: "75 Ω"


Unfortunately, the original Emotia I repaired doesn't have a setting for this. I did notice that its instructions state the following:

Picture too bright (MAC) 1.) Switch the termination switch on the Emac adapter "up"

Could this be due to a missing part? I Googled "Emac adapter," but didn't find anything. Any suggestions?

Are you sure that the original Emotia doesn't have a termination switch just like the Super E. on the back ?? Can't remember...
If Brightness is the only problem, you can always resistors to the output RGB lines by yourself. Cheap and easy to do.
