A Viewer called Matt asked if I would take a look at a very expensive GYS100.20 battery charger. He had taken it to a repair shop but they couldn't fix it. Let's see if I can figure out what's wrong and hopefully repair it!
I'm not an expert, but I do enjoy trying to fix things.

Well Mick, what can I say, you’re an absolute genius, you really really are. I don’t think I can ever thank you enough. Thanks also for strengthening the connector with the hot glue, hopefully this will help for the future. You’re right, it is in and out of our vans all day everyday and the vibrations while in transit couldn’t have helped. Seems strange how it would decide to pick on that one connector lol. I think it needs a BuyItFixIt sticker on the top of it so I can tell the story to everyone that sees it and asked 😊 Again thanks a bunch. Skills like yours are far and few between. Take care. Regards Matt

Can you give us a backstory on what you believed first issue noticed? Like Was the screen gone and then you sent off or it had other issues for it to believed broken. Because it seems weird to me that the screen wasn't diagnosed properly but the main board was touched?

@mattsmalley5780 2 ай бұрын

@@tdkyt46 that was the original failure, the blank screen. The back light could have packed up some time ago and I wouldn’t have noticed to be honest. Got it out one day and it beeped but didn’t turn on. Stripped the lid off and could see damage to the board and put the lid back on and that’s how it stayed for a few months and then I researched local electronic repair company’s and manage to find a TV repair shop and spoke with them and they said they could look but it wouldn’t be a quick turn around which I was fine with as I understand high workloads. Left it with him, after approximately 3 months I rang to be told he couldn’t repair it. Once I spoke with Mick I then removed the lid again to take pictures and that’s when I could see the signs of soldering to the main board etc. It was then reassembled and the next person to strip was Mick.

Good to know, I have one of these myself. By the look of it, those standoffs for the display don't hold it very securely so there will be some stress on the connector, I would imagine more so from being wheeled across a workshop on a diag cart that it would be installed in a mobile tech's van. Maybe the answer would be to use the same length standoffs but with threaded ends and nylon nuts - but your modified connector looks stronger than the original.

The display would have been the FIRST thing I would have looked at to make sure that the cable connections were OK. Also when you put the plastic glue as a physical brace to the socket, as I would have also done that on both sides. But apart from then few points, you went through it in a logical manner 👍🏽 Also one of the FIRST things that I had seen was that fan at the side of the unit.

My first words to local shops that bring me their problem jobs are "where are the original parts?" You know, the ones that weren't faulty in the first place. They are learning now, don't throw away old parts until you know it's a good repair. Sometimes, they have made the right call but they've sourced a part that doesn't quite perform to spec (or doesn't perform at all!) I have some really good customers though... if they're not sure, they won't fire the cannon, they send it to me for diag.

Nice repair, but I wonder if one of the mosfets in the PSU is not heatsinked properly? Seems like someone else worked on one of them, and the heatsink may not be touching the mosfet properly anymore. Might be worth checking out?

@BuyitFixit 2 ай бұрын

Thanks 👍 I doubt they got enough heat on that to remove it (as that was one of the things mentioned). I think they just touched up the legs with an iron.

year's ago we had a TV brand called PYE it was one off the earliest colour TV , my father even paid for extended warranty over a period of the the TV would play up. the service man came out many times and fixed it & sometime later the same problem would occur, so one while my parents were out I removed the back cover it had 4 or 6 circuit board & a cathode ray tube. so I unplugged all of the boards and inspected the PCBs I found on each board about 10 components not soldered properly in place, so I got my 15watt solder iron & solder & resolder the components then replace the PCBs plugged them in accordingly replace the back cover power the TV up & hey presto it worked better than before. it lasted 20 more years, I think what happened was in those days workers would fit components then another worker would solder they would get paid X amount of $ to complete then got paid so much per 10 to 20 TV sets completed. to get the bonuses they would rush the job & not doing a good job the QA man would check them to quickly.

For such an expensive unit, one would think that the design would be better. Great job as always. Did you figure out what that was between pins 1 and 2 of the wide ribbon cable? It looked like there was something stuck between the two solder joints.

nice charger, is the output of it capable of 100A? that would be pushing the 50A Anderson type connection.

@BuyitFixit 2 ай бұрын

That is indeed a very good point. I've just checked the connector and it is indeed a 50A Anderson, although it looks in good condition and has no signs of overheating. So either the connector is under-rated, the charger is over-rated, or they very rarely pull 100A.

@mrfrenzy. 2 ай бұрын

There is a calibration mode where the charger measures resistanse in cable and connector. It automatically adjusts output voltage at the charger depending on current to give exactly the requested voltage in the car. I guess they have made their own tests for how long the connector can take 100A before overheating and implemented in the firmware since the Anderson datasheet only lists temperature up to 70A. The internal forced air circulation probably helps.
