Help... Hub powers up... WD light flashes... then powers itself off. :-(

Guys, this isn’t a firmware problem!   If it ain’t going to boot, a firmware update is useless.

Have ANY of you actually contacted WD about it?

I’m from Singapore and I called my local WD RMA hotline this afternoon.

I told them that my first WDTV LH  (same part number as the others) died on me 2 days after updating to the latest firmware.

I have since gotten a 1-1 exchange from the store and the Hub is still on the stock FW (running fine after 4 days). I told them that I wasn’t going to update it as I guessed that the FW was screwy and the guy on the phone concurred, citing that the US technical support is aware of the issue. They have no idea when they’ll fix the issue.

See that the FW is STILL available for download, WD should be more responsible about the whole thing and issue a disclaimer mentioning certain batches should not update the FW blah blah blah. Instead, the consumers are the ones spending the time trying to figure out what the heck went wrong.

Sorry for the rant, it’s been a trying time as I rely on the WDTV to keep me sane by entertaining my kids when I have work to do.

I’m in Singapore also, well done getting the store to swap yours, my shop just handed me a photocopied card of the wrong service agent . Been all downhill from there on.

Sorry to hear that, I’m glad that I went with Challenger at Funan, getting it replaced was a breeze (quite unlike the rest of the stores here). I still can’t believe that WD Singapore told me not to update the FW even though it was on their website.

…I can certainly understand the frustration;  no one wants their cool toys to go belly-up.

But you’re concluding that the firmware was responsible for the malfunction.  It might be, but it’s too easy to fall into the trap of “It happened after that, so it must have been because of that.”   

To me, a 2-day lapse tends to indicate to me it was coincidence…   Nothing happens in firmware 2-days later… :wink:

Plus, who knows how many thousands of folks have had NO issues compared to the dozen or so here that did?    I’m one of them, and most of the people here are in the same boat… 

*I* wouldn’t want to be delayed a firmware upgrade because of some unknown problem that most likely has nothing to do with firmware…

Good News! I solved this problem. But it will require you to pry open your hub.

Out of desperation, I pry opened my hub to see if I can solve this problem. The first thing I tried is to remove the fan because fan consumes power and this seems to be a power problem, but that didn’t work. I also tried removing the hard drive but that didn’t work too.

One thing I’ve noticed when this problem came up is that the power button is not working so what I tried to do is to disconnect the cable connecting the power button to the mainboard and after turning on my hub, it works. I’ve tried several times to turn on and off my hub and it always works so I think the power button is causing the problem.

If you will see the inside of your hub, you will see the little board that contains the power button is seperated from the mainboard and the little board of the power button is just connected to the mainboard through a cable. Maybe the firmware upgrade causes conflict between the little board of the power button and the mainboard so disconnecting the cable between them solves the problem.

Do this at your own risk and you will be the one responsible if something is damaged in your hub by doing what I said and your warranty may be voided. I just would like to share to you what works for me. Tell us if it works for you.

This is your first post describing your problem:

'm having the same problem with the hub shutting down during the “loading mochi” screen and Iike RenMart, I’m also in Manila and my hub was bought in the U.S. so I can’t get a replacement. My hub is working fine for a couple of weeks and few days after installing the latest firmware 2.03.24 that when the problem starts. Hopefully there will be a solution to this problem without replacing the unit.

I note that you say that the hub worked for a few days after installing the latest firmware so I can’t really see how it also could be the cause of your problem. It may be that the switch / board / lead is in some-way faulty. Perhaps in your case the switch is stuck on.

After some tests I can replicate your problem and I believe that it is the switch that has stuck on. If you hold the hub switch in and then start the hub via the remote then it will boot up to the second boot screen but switch off before the user menu’s appear.

However I am glad you have got it working again but I would caution users that this a radical step which could cause further damage particularly if you could return it.

Upon checking the power button of my hub, it is not stuck and I don’t remember pressing it before the problem happened because I always use the remote to turn it on so I don’t think it’s physically stuck. I also indicated in my previous post the word “maybe” in telling the firmware upgrade causes the problem so I’m not telling everyone it is the problem. I’m just obviously speculating that it is the problem because that is the only one I did before the happened occured even though it is days apart.

As I said I have replicated your original problem by holding in the switch and booting up the hub. It acts in exactly the same way as your problem. Have you checked the switch with a meter or just by looking. The switch panel is basically a button switch on a pcb with a couple of surface mount components so there is no a lot more that it could be.

Of course the other explanation is that you could have somehow jammed the button and by playing around inside the unit you could have unjammed it.

We are currently looking into possible problems with the power button. I’ll post an update when I know more. Thanks for your patience.

Thanks very much b0y0ng99!!!

I knew there was something up with the POWER switch as it has never worked properly in turning the unit off/on.

Out of desperation, i looked for the notch at the back of the unit near the top and pryed open the WD. I looked for the connection of the power switch to the board and disconnected it.

Lo and behold, the unit came back to life!!! Wooohooooo!!!  

It’s forums such as this that is worth the visit for support.

I am now updating the firmware again to see if this will cause a similar problem.  I don’t think it will though.

Will keep you posted.

But you said that you could get the hub to work by cooling it down.

I’m on the old FW and the power button isn’t working for me, i.e the Hub is working fine but the button is inoperative.

Hi Guy_K,

So is it safe for me to update the firmware? I want to copy my movies over to the internal harddisk without  risking it being deleted in a FW update. Thanks!

Hi RichUK,

Yes I did say that.  But not without a number of attempts. So it seems not to be the solution.

All along I was suspecting the fan since this is the first that makes a clicking sound before the shutdown.

However, I did notice that the power button on the unit never seemed to work properly. But of course I ignored it.

Now it makes sense.  Disconnecting it from the board seems to be the best solution so far.

I am on 3hours running without any problems.  The firmware upgrade did not seem to replicate the original problem.

So if any of you guys have a similar problem, I suggest taking it back for a replacement.  But if any of you like me are overseas and no access to any store that would honor the warranty, then try out the solution proposed originally by B0y0ng99.

It works.

As I said in my previous post, I checked the power button and it is not stucked or jammed even before the problem occurred so how can I unjammed something that its not jammed? and I know what’s a switch panel is. How do you think I figured out that disconnecting the cable the connects that pcb to the mainboard solves the problem? so don’t tell me something that as if I don’t know what I’m talking about. And yes, you replicated the problem but that doesn’t mean that the power button is jammed. It could also mean that even though the power button is not pressed, that pcb is sending signal to the mainboard that it is pressed so that’s why there is a problem. And as it appears now, I’m not the only one who solved this problem using my method so the power button or its circuit board is causing the problem.

Agreed, much more likely to be some hardware component failing.

Something has a bunch of low spec ones that have found their way into these boxes.

Melamine filled capacitors from China or some such.

At the moment, we believe this is a hardware problem and is not related to the firmware.

HEY GUY _K, 

Thanks for the feedback :slight_smile:
