This repair came to very happy ending as I found a local shop who had the HDMI-AV adapter I needed to solve the problem, and it worked perfectly. I still have some of them ordered from AliExpress to keep as stock when they arrive.
I think you can be happy that he accepts that solution as I would not have when i pay for a repair i want and expect a propper repair but that's me !!
do you have more motherboards repair comming up Richard as I believe you had a bunch faulty once you had to repair ? I always love those video's and about mr. Bleep would you want to send one to australia ? i bet that eevblog wants to test it.
@@Dutch-linux I don't really see how this point of view would have helped the customer. Sure he could say it's not good enough and decline the repair then sit there with a beer watching his own customers in the next door bar watching TV, or he could be up and running with a bar full of happy customers earning him money. I'm not sure you would really do any different, it makes no commercial sense.
Makes far more sense to run HDMI!
Thanks, for showing us around. Nice island. Blessings
And "scenery" it is!! I'm sold, I'm moving!!!
Great aerial footage and videography! Not hard to see why you left England!
@James_Bowie We decided to make a bit of video while we were at it 🙂James, if you appreciate a bit of *videography* have a look at this video if you like, this is Detlef, Julie and myself working at the best of our current ability. You may like the 'fake' crowded bar drone sequence and some of the camera movements. Note:
A: this is not a shameless plug for our other channel. Oh go on maybe it is. 😋
B: Note this video features local nightlife and not a lot of clothing at times. Filmed mid November 2023 ua-cam.com/video/JCWsRMvpdD8/v-deo.html and a good example of what we can achieve so far but we are still working to get better
Or another one ua-cam.com/video/nxtUY5GtgOQ/v-deo.html, This is Julie and Myself working together with two cameras (yeah she tends to film the guys so I counterbalance it) Det was otherwise occupied on this particular night
Good video, and that drone dodge lol. I fancy a trip away now myself :)
Great Video Richard Love the drone footage and the music, and what a lovely place to live better than UK
This shouldn't count as work you lucky boy!,thanks for the content,appreciated.
So I'm in a bar and I can't have a beer! That is working, I'm telling you 😝
I like the intro scenes and the music.👍

Nice weather os what we need right now.. 😊
Hope you enjoyed it. Sending a little bit of sunshine to you from Maspalomas 😁🏖☀
I hope you enjoy your time in the beautiful Canary Islands. I'm from Gran Canaria, where you currently are, in Playa del Inglés. It's a very sunny day. Have fun!
@nesetorusan Ive lived and worked here for over seven years, I'm not living in Playa del Ingles, I'm in San Fernando which is about 20 minutes walk into the resort for a night out or to go to the beach if you want it, but just another 20 minutes walk the other way if you want a quiet night sleep and to buy food and stuff at local prices not tourist prices. 🤣 Actually we are going to Las Palmas this coming weekend for three nights filming the Carnival - you will find that and more on Gran Canaria Uncovered. www.youtube.com/@GranCanariaUncovered
Where do you live now?
@@LearnElectronicsRepair Actually, I'm living in Las Palmas de Gran Canaria, about 5 minutes by car from Las Canteras beach.
Greetings and have a nice day.
JFTR: PCM is "pulse code modulation" and means the audio stream is decoded in the box, and then sent as uncompressed audio (basically like a WAV file) to the TV. Bitstream means the box doesn't touch the encoded audio and just passes it through. Then some other device further downstream (the TV, a sound bar, an AV receiver, etc.) needs to decode the audio and send it to the speakers. Both have pros and cons. For instance, PCM can't do complicated multi-channel setups and fancy stuff like Dolby Atmos. It also doesn't support wireless transmission. Bitstream OTOH requires an audio processor downstream that can interpret the data.
I don't think it's the case here (since AV is all analogue anyway) but I've had cases where this setting mattered. Someone had set their player to "bitstream" and the old TV couldn't make sense of the newer codec used, so there was no sound. Switching to PCM fixed that.
Yeah I've seen these sort of problems, where the box will give sound on one TV but not on another, and that was with the TV connected by HDMI. Thanks for the info, I now understand the cause of that much better 😁
@@LearnElectronicsRepair it worked before so something just went bad in the box. I'm sure no one is playing with the settings. The audio will require either an opamp chip or DAC chip connected to the jack so that's likely to be where the problem is. It would have been future-proof if the guy just used hdmi cables for everything then he can use any available box because hdmi is the main a/v connector used now. Perhaps a future job where you swap out the av cable for a hdmi cable to avoid this situation next time when the whole box gives up. Order the long hdmi cable and fit it at your leisure :-)
@@g4z-kb7ct HDMI is not the easiest of solutions, there are quite a few TV screen in this bar, not sure how many but maybe eight or so. The screens also have an input from the Karaoke system. In my experience using HDMI leads of various lengths and a HDMI matrix combined with TV of different makes is very problematic. He would need at least a 4x8 HDMI matrix if not a 4X16 which is quite expensive and a lot of long HDMI leads which will add up to some hundred euros for the cables plus installation and it probably would not work very well even when it was done.
A better solution is to replace the analog modulators with DVB-T modulators and then connect HDMI to the video sources. This is much more reliable, and gives excellent HD quality video (as good as HDMI) using the existing UHF coax. It is also very forgiving of old coax wiring as you can crank up the UHF output power. Also the method of use is same as the analog system he has now (just select a channel on each TV) rather than teaching the bar staff to use the video matrix properly. And if one DVB-T modulator fails you can connect whatever source you want to one of the working ones as a temporary fix, whereas if the HDMI matrix fails the whole system goes down.
Even with that DVB-T upgrade I have seen some older TV that won't work with the video signal from the modulators. It seems some tuners don't like the MPEG4 encoding or something like that, or they refuse to recognise each channel as being different for some reason, so they scan all the channels in during automatic or manual tuning but only store the last channel scanned (Toshiba I'm calling you out here!) So if he does this upgrade don't be suprised if he needs to replace one or more of the TV too.
Awesome view!!
Also an spdif converter
Yeah that could work too. The HDMI-AV did the job nicely.
love the video at the start of the program
Should have scoped the traces at the connector and traced back, as you say the chip further back is likely the issue but it would have ruled out the connector 100%. That weather there is horrific, I think I'll stay here in the UK in this balmy 3°c
Agreed but sometimes you just need to fix stuff whichever way keeps the customer happy and makes a good return for your time and work. I'll accept the horrific weather here as the price you have to pay to escape the UK and find somewhere cheaper to live LOL 😋
Have you used MG Chemical 63/37solder? I am really struggling to choose a decent solder. I can not afford a roll of Kester 63/37. Any suggestions please what is your go to?
In US it's Florida, in EU it's Canarias
Hello. Do you accept orders for electronics repair?
Big Lol at 1:15 checking out the girls 🙂
Well... you know... it would be rude not to 😅
trees growing right up at the shore, that's interesting, dont have that here
I never know or have any idea what to change people in situations like this. Charge $120 service call just to inform them they need a $2 part? Or do you tell them how much the service fee is upfront? I dunno. Need your guidance.. thanks
probably a opamp you should be able to repair that !!
Probably. But if the adapter is cheaper and works just fine, the customer will probably be satisfied. Mostly they want a solution and that solution happens to be cheaper than a proper repair... It's always up to the customer of course, but a real repair job might be priced a considerable magnitude higher and having to wait for longer as well if a defective part is not in stock.
@@LarixusSnydes a 30 cent opamp is never cheaper then the adapter .. depending what he charges for his time... and with finding a adapter and then rewire it there at that place may even cost him more time then to replace that opamp there at that output plug !!! for me i would never accept such a solution
@@Dutch-linux You think that the proper way to handle this would be to order that opamp ( since he did not have that chip in stock ), furnish a Hdmi2AV adapter in the mean time and when the part has arrived, contact the customer to plan a proper diagnosis and if possible repair the box so that it works as described in the manual? The priority of the customer will be to have stereo sound again in order to attract his customers to come to his bar.
... an op-amp ...
... an adapter ... (a when the following word begins with a consonant, an when it begins with a vowel!)
@@SpeccyManThank you for this lesson in English 😀. It's not my native language, but I'm always eager to learn.
How is your legal situation? Since you are out of the EU?
So…do you speak Spanish, Richard? I’m from Madrid! Nice place to live, Canary Islands…
Yo habla un poco Espanol, pero con mas cerveza yo habla mas 😉
@@LearnElectronicsRepair haaahahaaahaaa!!!! Nice comment, Richard! 😂 If you need something from Madrid, here I am. Real name is Jesus. I’m a PhD in electronics engineering. Retired (66 years old), but with an always insatiable curiosity.
Great video! Just a question are these just regular Android boxes or special ones?
They are Linux boxes
That hdmi to av converter box did not appear to pass through the hdmi signal and the receiver box only had 1 hdmi output, so how did the hdmi video get to the screen? Perplexed 😕
The boxes are connected using AV leads to modulators in the bar (one per box) then to a UHF distribution amp and RF aerial cables to all the TVs. The modulators are set to different UHF frequencies. You tune the TV to each channel, then select the channel number you want to watch on each TV. It's quite simple, the customer was not previously using the HDMI connectors at all. This is why I couldn't just sell him a new box as the more recent models don't have the AV connector.
Looks like some wear on the south cost of England, judging by the looks of how many English walking about .
Wondering why you're not putting a probe on the inputs of that DRV632 driver IC? If it maybe was that, and since you needed to order stuff anyways I mean.
More that the customer was desperate to have this working same day, so I went to find an HDMI-AV converter instead 🙂
@@LearnElectronicsRepair Makes sense, in the video you seem to have given up on a same day repair, so that's why I asked. I think I would probably be too curious myself not to probe that, if for nothing other than learning about the device failure modes for the next time I get one in my hands. But admittedly I do tend to get into rabbit holes when I do repairs 😄
@@fixfaxerify I Agreed with you It's quite interesting to do stuff like that, and it would have made a better video too. 🙂 I did comment that even if the IC was the driver for the AV output and it was faulty, that I didn't have another scrap box of the same model to salvage a replacement part. I do have quite a few scrap MAG boxes of other models and I have fixed a fair few on this channel before now as well.
Can I record From my streaming device to an old VCR if I use one of those HDMI-AV adapters, or is there a piracy/content issue that will scramble the video?
The adapters somehow ignore HDCP 😉
@@LearnElectronicsRepairTrue, but if you are recording from a VCR I would be more worried about Macrovision, rather than HDCP. Old as that protection scheme is, it's surprisingly hard to defeat even these days
LOL. Perv! hahaha Good on you!
