Hi all,

Have a small problem. This cable is disconnected and I think its why my BV47 won't power up. I have just reconnected the TV after floor sanding though this cable location seems to be missing from both side of the BV7 rear panel diagrams.

Hope someone can help as the Aus Open Mens tennis final is about to start.

Looks like the connector for the stand - where does the other end go to?

But the BV7 should power up without that.

Do you have the other cables in the right places Whistle

Is the standby red light showing up?

I think it is as well. I have had the problem before.

No it does not, this cable needs to be connected somewhere, its not obvious.

No red light.

... I do have a cable connected to the stand socket on the back of the TV. It look like a larger version of the one pictured and originates from the stand. If that helps.

I'm not sure. Cables into the back of TV were disconnected when it was moved. Its across a parquetry floor in cable sleeves bound fixed and taped. This was one of the cables that came from the rear of the BV7. It is sleeved (heat shrunk) in bunch that had the Digital audio in, and IR control out and its exactly the same length.

The power cable into the BV7 works, I tested it on a speaker.

The Stand connection into the BV7 has the same pins (looks star like), though its about double the pictured cables size.

Looks like a s-video connection to me.

Do you have aditional equipment attached to the bv7?

Ok, I think that is an s-video cable but you haven't mentioned which type of BV7 you have so it's difficult to indicate where it should go, but in any case it would not be what is preventing the TV from powering up.

When the power cable is plugged in does the dvd eject if you press the eject button on the TV?

On my 7-40mk3 there is a group of ports designed to be accessible when the TV is mounted, They are hidden behind a sprung flap near the top right corner when viewed from the rear - It's likely that the whole bunch you are describing were plugged into this section.

Could be a s-video connector.

Only s-video in on the BV7 I know of, is the one In the AV socket 6 on the side.

But connected or not should not have any influence on the powering up of the BV

I should also mention that the connector has two cables running into it.

The s-video is not available on any BV7, so my guess is you have a scart-adapter (with s-video) lhat should be in the back of your tv, or still is...

Another guess,,, You think your tv is off, but it's not. There is just no input.

A pic showing the two cables.

There is a lot connected to this TV.

The TV has the following connected. TiVo, V8000, WII, BG4500, AppleTV. its masterlinked. The BS9000 is in the same room, as with BL1's and BL4000's and a BL2 which was used to test the power cable. To watch the Tennis I connected a Samsung TV to the TiVo.

The BV7 - 40 stand is connected into the Stand socket on the BV7. The BL7-4 has its power light on. Masterlink is connected, IR is connected, Power is connected, so are the powerlink cables, digital audio, ir cables and more.

Hope that helps.

Not true, AV5 has s-video connector on my mk3, and is separate from the rest of the connections so would explain why OP can't find it.

Yes, that was my suspicion too, which is why I asked him to try pressing the eject button for the DVD (if it has one) as this would at least confirm the TV has power.

Some 7-4' have power-in and -out.

Means you run one cable to the 7-4 and then another (short one) from there to the BV7.

In other cases you need seperate powercables for both.

@riverstyx 

But still it should make no difference if there is something connected there or not!

Okay, your right.

Let me rephrase my earlier post. S-video connection is not available to the versions, beoaus has posted. These pictures are from an older BV7 without hdmi.

Yes, I agree, and both you and I have stated this already, although as DoubleU has suggested there is a chance that the TV does have power but no source and hence just a blank screen.

DoubleU:

Apologies DoubleU, my previous posts were a little rushed and having re-read them it could easily be interpreted that I was trying to correct you forcefully with picture and allEmbarrassed but the picture was aimed at beoaus to assist him in locating the extra connectors - having looked at the manual for the mk1 you are right, there is no s-video input so your suggestion about a scart to s-video adapter is the most likely option I can think of.

I think we really need to confirm whether the TV has power first (eg with dvd eject button or trying to enter the menu) and work from there. This may mean beoaus removing everything he has already connected except for the power cable and centre speaker and working up from there to identify where the problem lies

Kind regards,

Martin.

Without all the cables, you only need the powercable on the BV7 to get a standby-led. This cable is vertically placed at the back in one of the top corners. You could check with a seperate powercable directly from the wall mains outlet to the BV7.

Hello again,

Its a BV7-40 MKII. The DVD does eject. I have tested the power cable into the TV with a speaker and it works. There is still no standby light on the TV though. There is one on the 7-4. I tested the sources being a TiVo and it is working as is the HDMI cable and its DVI converted into the TV.

The cable I showed earlier only has 4 pins, the same as a cable into the stand socket of the TV an inch from the power cable. So I think. its the key

I had a similar problem once before and the tech reconnected this cable noting it splits power somehow and somewhere. I was not there to see it though he did say its connected in a difficult location. At least that is what I understood.

What stops the BV7-40 MK11 powering up? Does this cable support the stand and TV power somehow?

Thanks all.

The TV only needs the power cable connected to power up. If the DVD tray responds to the eject button being pressed then it has power.

Please try pressing TV then MENU on the remote and see if anything appears on screen.

I am almost certain that the plug you have photographed is an s-video plug and the fact that it is bunched together with a set of source related cables would also indicate this.

Are you sure you don't have something similar to one of these plugged into one of the SCART connections of the TV:-

From memory, the plug for the stand is larger than the plug you have photographed, but in any case would not prevent the TV from powering on,

Kind Regards,

Martin.

Right!

If still nothing happens, I suggest you unplug the power AND masterlink from the TV. Wait a minute, plug only the power back. 

Maybe the ML is blocking the tv to start.

Long shot, but worth a try.

The DVD does eject - means 'powered on'.

Is that the only thing that works?

No screen-menu, if pressing 'TV' and 'MENU'!

 

I would say - do as DoubleU suggests.

It has been seen before that a false ML can block a BV.

If that is the case - do check your ML-cable or -junctionbox (if any).

Try running another (new) ML-cable between the BV and the BS.

I meant a 'ML-reset', not replacing the cable. One step at a time. Wink

All solved!

We played around for a little while, and scratched our heads for a bit longer as we couldn't work out the problem. So we decided to unplug EVERYTHING! Then we plugged in the Masterlink first, then the power. The TV woke up :)

Connected everything up and got it working. There was a little bit of 'two steps forward, one step back'; but in the end there was glorious sound and picture from all sources!!! Yes - thumbs up

Well done, excellent news.

I'm still curious, what was the pictured connector for and where did it connect in the end given the mkII doesn't have any s-video inputs?

Kind Regards,

Martin.

It was an unused S-Video plug. It was there as it was from a previous setup, but because all the cabling was cable tied and covered it was too difficult to remove.

A big thanks to Jonathan and all those that posted. After moving back into our house for a few days it was a relief to get the TV working. Having a second set of eyes and a methodical approach to boot solved the problem.

One item that came up was my incorrect connection of an IR blaster into the IR socket. The IR socket is used for a remote IR Eye used when a projector screen covers the Beovision. I wonder if it shorted out the TV somehow?

Again thanks and on to fixing the digital sound problem...(low priority)

I'm pretty sure than when an external eye is plugged in it disables the internal IR receiver in the TV, so this could well explain why the TV was not responding to the remote control.

I'm glad you got it sorted.

Kind Regards,

Martin.
