It means that item was never dispatched. Recommended solution is waiting till protection time will end in like a week and open the dispute. Opening dispute early may result in loosing it. Of course you can contact the seller and ask why item was not dispatched.
I have just emailed them to enquire whats happening. Thing is that for the last 9 or 10 days it was shown on the tracking system as dispatched, in transit??

It was shown as waiting for pick-up. The fact that tracking number was created does not mean it was ever dispatched.

Well according to an email I got from Aliex on 14th Jan it was dispatched but when I never saw any activity on the tracking I contacted the seller directly on the 18th Jan and was told that they were ready to dispatch it.

Given the hassle factor and that it would seem that the seller is not being 100% truthful with me, I shall be requesting a full refund via Aliex and I have now ordered another from another supplier who assures me that the one they have is identical to a photo I sent them, so fingers crossed it is and it arrives.

To be fair it might be more to do with incompetence rather than actual lies. Bad seller any case  :--

Could be right, but I haven't told the whole story, they kept saying for days before the email arrived from Aliex that they were ready to dispatch it, so if they were, why not do it then. I ordered the board at the same as I ordered a lot of T12 soldering bits and bobs from various sellers on Aliex and that was dispatched and traceable for days before I began to ask this seller questions about what the delay was ..

I had gear coming from 5 different sellers, all ordered at the same time and the other 4 have delivered and one actually delivered in only 2 weeks and they all said the items were in stock and dispatch would be within a couple of days once payment was received. Payment was done at time of ordering and bank records can prove this, so speculate as much as you want just what could have happened. I have messaged them numerous times and never once have I had a straight forward answer to my questions. Its not my idea of how a business should be run or how business should be conducted.

I have raised a dispute about this shipment with AliEx and they agree that it is abnormal and said that a refund was in order and I should see it my bank in a few days time.  :-+

EDIT, Update, AliEx have processed the refund already, they did it within about 30 minutes of me raising the dispute with them, so well done AliEx, respect to you for prompt action.

An update on this long winded repair, I ordered a replacement board from another supplier on AE and the first one they sent never appeared on the tracking system and when I questioned this they said that might be due to bad weather delaying the shipping and asked me to wait a bit longer. I did that and a couple of weeks later, there was still no tracking info so the supplier sent out another and gave me a new tracking number for it which worked perfectly but only while the item was in China. Once the airline took control of it, all tracking stopped but today it arrived  :clap:

It does rather have the look of being a brand new board, there is no evidence of it ever being fitted into anything, no marks left behind at all at any of the fixing locations?

However it come wrapped in bubble wrap which is worrying because of the risk of static and it is bowed as can be seen in the photos. I shall be fitting this shortly and see if it works or has been damaged in transit, the seller has been informed.

I have one for it but it might be too thick at 5mm as ordered it after I had reassembled it 3 months ago. I may have to try and reuse the old one or use spacer washers, at least to test it with and order a thinner one if it works.

From mobile device so predictive text might have struck again [emoji83]

Managed to reuse the thermal ad from the old CPU on the one, and fitted the board, switched on and nothing at all on the screen so it looks like my worst fears have happened. I refitted the old board and the same thing, not even the colour bars this time around so maybe the screen or the ribbon cable has gone has gone. In a darkened room it is possible to see the screen backlight working and can be dimmed or brightened on the control panel and it would seem that the logic panel is working OK as the monitor will only switch on once it is receiving a video signal so switching of the computer also switches off the monitor which is a neat design touch.  ;)

The monitor itself is a pig to work on as the screen is held in place by being sandwiched between the metal fascia and the metal back cover so it has to be laid flat on its screen making it impossible to watch it while prodding and flexing things to see if anything changes. You have to fix it together temporary with sufficient screws to hold it all together to stand it up to see what if anything is going on with it so its a long winded process to do anything with so in that regard is a crap design. Surely its not beyond the designers imagination to devise a way of holding the screen in the fascia so you could work on it as a whole item less the back cover  :rant:

As parts and information for this are as common as hens teeth I think its time I cut my losses and either offer it on Ebay as spares or repair or just dump it, then I can get my bench back again and get on with my radio repairs / restorations instead of twiddling my fingers  :palm:

You mean just like any other monitor? I don't see any design touch here.

No I don't, most monitors that I have seen, used and indeed own and between the family we own a few, do not switch off when the computer switches off. The last one I had like that (apart from laptops) was an early IBM clone by Amstrad, a PC1525 and a PC1640 which shared a common power supply in the monitor. Most modern computers have a LCD monitor which has its own dedicated ON/OFF switch and power supply so the computer can be switched off but the monitor is still on. Screen is blanked but the system is still powered up and the power light will blink ON/OFF meaning that to be totally green you need to switch it off via its own power button.

So what's the difference? There is no LED light on front bezel when it's in standby mode :palm:?

And what makes you think it's completely switched off without video signal present?

I don't know what you mean, we have 2 LG 24" monitors, 2 x Samsung 23" monitors and a Samsung 19" one and the all have LED's on the front and these flash and a darkened room you still clearly see that the monitor is powered as the screen back light is on and is visible as a grey screen, not visible in a lit room but at night time it plainly visible if the lights are off. This means that they are drawing power and not only wasting valuable screen use hours but are also a possible fire hazard to say the least.

I'll ask you again, why do you assume other monitors are not drawing power when you "switch them off" with power button. There is no hard power switch, they are always in standby regardless if LED is blinking or not. It might be just they draw less power when you "switch them off", but not guaranteed. And for some stupid reason assume this monitor is not drawing power without video signal present?

Any monitor switches off backlight when no video signal is present.

Yes I do know that just because the monitor has been switched OFF via the button on the front that it is still drawing some power, but that level of power being used is much less and so is any risk associated with it.

No, not every monitor nor TV for that matter switches of the back light when the video signal switches off. What happens is that the pixels are effectively switched off because the polarising action ceases as the transistors are no longer getting instructions to rapidly switch on and off according to whether the pixel should a bright light source of a dim one etc, they go to their resting state which assumes that they are supposed to be blocking the transmission of the light from the back light through to front of the screen.

This is why the back light can be seen most clearly in a blacked room when the monitor or TV is still switched on but not getting a video signal, its looks like a dull grey screen and switching the display OFF you will see the screen going really black.

If you have satellite or cable TV, try turning off the receiver box at night with the lights off and watch the screen, then watch again as you operate the switch to put the display into standby mode, it really is very clearly visible.

I have also double checked this with a power meter, with a video signal, the display will draw its maximum power, disconnect or switch off the source of that video signal, the power consumption of the display unit will drop again, use the TV remote, or the touch switch/pad on the monitor and you will this power consumption drop yet again as display circuits and back light LED's are switched off, the unit should now only be drawing 1 or 2 watts in standby mode ready to come again when you operate the on control be it directly on the monitor or infra red via the TV remote.

As you rightly pointed out, there is no actual physical power button any more.

In the case of the Crossover monitor, if I switch it on without a video signal being present, then after a couple of seconds, it switches off again. Give it a video signal and switch it on, it will remain on as long as the video signal is present. Remove the video signal, the monitor switches off. Reinstate the video signal and the Crossover remains off until I press the wake up button, so the video signal does actually switch off the monitor into standby mode.

The Samsung and LG monitors and TV's will spring back to live instantly again as soon the video source is made available.

Physically check it and see.

Obviously you have no clue. Dunno how you got the impression that backlight is not switched off, but you are completely wrong about this.

BTW high resolution displays are generally pretty slow to boot up from standby. Except some 30 inchers without scaler board and therefore no OSD as well.

All I'm saying is to try it for yourself. If my wife gets up and goes to bed and switches off the cable box, the TV has no picture nor sound being emitted. When I go round the house at night before turning in myself, checking that doors are locked etc, in a pitch black room I can physically see the light dimly radiating from out Samsung 42" LCD TV and it also has a sort of swirling pattern to it, getting the remote control and pressing the power OFF button, the light and fussy swirling disappears and the screen goes jet black and a RED LED on the front lights indicating that the set is now in standby mode. If as you say, the back light is off, can you explain to me then just where this visible light is coming from??

TV is not the same as monitor. It does not switch off automatically unless there is setting to auto switch off after some timeout without signal present. Think about how TV works, you are supposed to be switching between channels and video inputs. Say, you switch off TV box. If TV would automatically go into standby, you no longer would be able to select other video source or TV channel.
For Samsung:

Depending on your TVs model this may be available for you. The option is included in Eco solution. Go to menu > system > Eco solution > no signal power off.

On the other hand, monitor is supposed to work only when signal source is present on the input and there is no remote you will play with. TV is a standalone device, monitor is not.

Arh, yes that now makes sense, thank you for enlightening me, however my original comments about the Crossover is still correct in stark contrast to the other monitors. The others will display images as soon as the video signal is present, provided I have not physically touched the power button. The Crossover will not, you have to give the power button a press to bring it back to life again, which to me is a good feature  as I like to switch off when not using anything.

It sounds like faulty scaler board, not feature.
