Sony Ericsson MBW-150 OLED repairs

PVTD said:

I have a never used MBW-100, but I think the battery is dead as it shows charging when attached to the charger + once fully charged (Logo showing full) and unplug the charger, the screen goes blank and the watch stops showing correct time.

The weird part is, I have the dimmed problem too, almost invisible, BUT when I unplug the charger, for a fraction of a second the screen brightness goes very bright, shows perfectly the battery and falls into it's end. 9 out of 10 times I get that situation...

Is it really the OLED being dead??? Couldn't it be a different problem?

Thanks,
PVTD

You are totally onto something! Anyone who opened their watch, are there any discrete elements on the motherboard?

I've seen that too; never quite knew what to make of it.

There are no discrete elements. I posted pictures of both sides of the circuit board earlier in this thread. I have replaced batteries in two of my three MBW-150s. They all have completely faded displays, but I have never seen them flash to life when removing them from the charger.

Ever since I switched from Windows Mobile a couple years ago, my watch batteries only last almost exactly six hours before they get too weak, and vibrate and turn Bluetooth. I have posted about this before but apparently no one else has this problem. I have been through multiple Android phones, ROMs, kernels, etc. but they all act the same.

Hi PVTD

About your problem with dim Oled and battery.
Your Oled might be ok, is possible that you battery needs a jumpstart.
Open your watch and take out battery (easy with the socket)
Use a 3,7v (18650) battery or other fresh battery adding up to about 3.7v.
Now take a cable from to + to + and - to - for some minutes.
This will give battery a lot more juice to wake it alive.
After this, connect to normal charger to top up battery.
I have had a 150 lying for 6months before use and sendt it in for warranty repair.
I got reply they could not replace battery.... I got watch back + a warrany package deal replacement of a Mobile SE Experia mini pro (that i sold).
Jumpstarted battery and works fine since (4months)
Reason for me to expect that your Oled is ok, is that it shows light when charging.
Watch does not show any more light than their faded state.

Now you all folk asking for my project replacing Oleds.
I was promised and I also paid for Oleds that never was shipped due productions stop. I got refund of course.
Seems like I am walking the same route that others here have.
My apology for misleading you guys and giving you hope.
I have for a long time been looking all over for a 31pin (downline) Oleds.
They just dont seem to be in production any more.
I think that these 31pins have been replaced by 14pins sideways. These 14pins Oleds gives us the possiblity to connect,,, because not all 31pins are in use. Problem with 14pins Oleds is the driver SSD1 that is sideways. There might be space problem to allocate driver sideways. ( going this way with sideways driver and 14 pins connection , is that connections must be cabeled (14).

There is a company saying that thay have some 31pins stock left but not willing to do deal. I do send mails hoping that they will ship that small stock they seem to have.

If all this ends up with no fix we can look for the Meta analog watch that is the next best option. This watch does not have the same battery life as the 150 but its is a good replacement i think .
Now the sony Smart watch is coming for 150usd. 3-7days battery life .
I may be going this way after my 150`s are dead. or maybe a Wimm One.....?
Definitely not the I`mWatch because of the terrible batterylife of 8-12hrs.
I think we will se more and more new watches coming to market.

I have same problem with my mbw-150.
Did someone else try the jump start of the battery?
Does it work?

Thanks

What was so terrible about your fake one? Did you have the two button LM958 like this one? http://www.thinkgeek.com/gadgets/watches/c16c/ How long did you use it, and did the display hold up? If so, I'm thinking about just getting one of those and be done with it, or I might even be interested in buying yours. About all I use are the caller ID and text message notification anyway.



Have you contacted the companies you mentioned to find out if their displays are compatible with and available for the MBW-150? What did they say? I have the display removed from one of my three MBW-150s, and it's pretty much a paperweight until/unless this gets resolved.

I've got two paperweights myself, but my son has been a handful lately and we moved and i've got another son on the way. I'd love to see whether those displays would work.

I'm sorry to say that even without a working display, my Bluetooth connection only lasts about six hours before it kills the phone battery enough to turn Bluetooth off. I haven't seen anyone else with the same complaint, but I used to get a week or so on Windows Mobile. I have had the same short life on every Android phone and OS version I've been through for well over a year.

Have You Ever

I have found that many of these issues are caused due to moisture. Yes, I know it sounds darfed but the tiniest amount of moisture can cause havok with oled and other components. All you can do is put your device inside a tub of rice. I know, weird hey but it works, the moisture is literally soaked into the rice and away from your device. Even the moisture in terms of air humidity can have a small effect that causes havok. There is even a tiny creature that feeds off metal and other bi-metal components and they slowly create strands and inter connective fibers between circuit components from their tiny little dead corpses. They rely on any moisture available, so best be certain your device is humidity free before trying expensive repairs.

Were you able to revive your MBW-150 OLED display with rice?

No, however my grandmothers ipad, my previous sgs2 and my nephews Nokia N9 where all saved by this old trick of the trade. Sucked the moisture out.

The watch is supposed to be waterproof. I doubt soaking it in rise will revert the display, even if you open it before putting it rise.

I ended up using my MBW150's as regular watches. With Bluetooth off, battery lasts nearly 4 months (slightly less on my older one.)
That - until decently looking Bluetooth watch gets released by somebody.
Tamagotchies like the recent Sony Smart Watch or LiveView do not count. TI's analog one looks kind of boring with that shape and I also prefer metal wristbands.

Display not working has one advantage - battery lasts much longer and on the phone too (well... J.K.)

The waterproofing membrane relies on pressure to keep it sealed when under water. Atmospheric pressure changes can result in water passing through this membrane inn a process similar to osmosis. Rice can reverse these effects.

What membrane are you referring to? I have one of my MBW-150s apart, waiting and hoping for a new display. The only thing I see that would make it at all waterproof is a thin O-ring that fits in grooves in the top and bottom piece.

Yip that is the one, the high quality ones are made from breast implant grade silicone compound while lower quality ones are usually plain rubber.

Did anyone thinking of GB-6900 from Casio? It got 2-year battery life.

Just a data point that I bought one of the last few MBW-150 Classics I could find on eBay just a couple months ago and the display is already dimming, even though it was, or at least appeared completely new in box. My earlier MBW-150 had lasted about a year and a half before the OLED faded. Very disappointed, since I spent $120 on it, but alas.

I did get it wet, and I'm trying to think if that occurred before the dimming began. Might try the rice thing as a hail mary.

For now, I'm seriously considering the Pebble watch, even though it's not a traditional "watch", which is a big part of what attracted me to the MBW.

So did anyone succesfully chande display on this watch ?

Apparently Ninjarider's displays never arrived. Has anyone else been able to find, order, receive, and install a new display?

I want to learn who нибудь ordered and received the OLED display??
Where it is possible to order and buy it??

Att Nforce

Im trying to reply your PM. I am unable to reply to it. I dont know why....
maybe its my browser...
Please advise if company have confirmed stock.
My experince is that some resellers take on orders and cansell them due to fact that they are not in stock/production any more.
Please advice as I will try to resolder a new oled.

My e-mail: maikllll@tochka.ru

I too want to solder new OLED, but I can not order and buy OLED anywhere!

If who saw on OLED sale, tell to me where??
