Chosen Solution
I have a Sony kdl 55w805b TV that I’ve been using for around 5 years. Today while I was watching Netflix, Tv just went off after a popping sound(can’t define it exactly). Also the related fuse/switch (not the main switch just the related one) in the house main electric panel for the plug went off at the same time. I first unplugged the powercube https://www.powercubes.eu/wp-content/upl… A sony soundbar, a mibox and a vdsl modem were also connected to the cube. I’m not sure if the pop sound come from TV, power adaptor or from the fuse/switch of the house’s power panel. I reset the switch on the main house electric panel. And tried to plug the powercube again but same popping sound came again and again the related switch on main house panel went off. Then I unplugged all. (I reset the switch/fuse on house electric panel) And tried each electronic device on another plug (second plug). All worked except the TV. (without the powercube) I thought maybe the problem is at the plug. Then I tried a vacuum cleaner on the first plug (without the powercube). Vacuum cleaner worked without any problem. I also tried it with the powercube, worked without a problem. Then I tried to power the TV (on second plug without powercube) Firstly I waited after unplugging TV for 30 minute to make a power reset. I tried plugging TV on different plugs. I renewed remote batteries. But even when I use the power button on TV, there is nothing at all. No light on the status led, nothing. I didn’t get any strange smell or, smoke right after first pop sound. TV’s guarantee period is over and I’m not even in the country that I bought it. I love that tv especially because of really low input lag. The TV has some kind of power adaptor. (acdp-120n02) I hope the problem is with the adaptor. If it is maybe buying a new one will solve everything. I just want to get some insight about the problem. Am I being too optimistic. Does it sound like a bigger and not easily solvable problem ? Update (07/24/2020) Thanks for your answer, I went to a local electrician to check the power supply ACDP-120N02. Electrician said it doesn’t supply voltage and that it is defect. He gave me a alternative power supply that told me to check if the TV will turn on with it. You can see the images of the power supply below. (I used it with the M8 Tip for 19.5v 6.2A) https://photos.app.goo.gl/jxz8y3M76VJu3i… I tried this power supply and the TV turned on normally. The Tv’s guarantee is over. But I’m not sure about using this third party power supply. (it is 36 euro) I’m not sure of this power supply’s quality, tech spec says it has some protections like Over-temperature-, Over-voltage-, Over-current-, Short-, Over-load-protection http://www.dot-media.gr/pdfProduct/08013… And power supply feels heavy (I don’t know if it is good sign of quality) I also read something on box saying, “autorest to the lowest voltage 15v after current interruption, for maximum protection” Is this a good thing or not recommended thing for my TV. (on TV label it is 19.5v 101w) But maybe the original power supply has some other kind of protection especially for the TV itself as design. I contacted Sony service for an original power supply waiting for response. Local electrician says Sony will probably provide a third party also as this power supply model is a bit outdated. And he says he is using that EP-120 third party power supply for around 7 years and it is good quality. I don’t know if he is just saying this to sell :D So should I use the third party power supply ep-120 120w or should I search for the Sony labeled original power supply?
Hi, There is always a reason why a circuit breaker trips, usually because the current passing through it has exceeded its’ rating. If you have a DMM (digital multimeter) and know how to use it, measure the voltage output of the TV’s acdp-120n02 power adapter at the adapter’s plug that connects into the TV when it is connected to a power outlet. It should measure 19.5V DC. If there is no output or it is not this voltage at the plug, then the adapter is faulty and needs to be replaced. If the adapter’s output is 19.5V DC then you will need to start checking the TV to see why the standby power LED is not on when the power is connected. Here’s the service manual for the TV which should help you to find the problem. Be patient when going to download the manual. After you have passed the I’m not a robot, test and clicked on Go to Download, below the document preview box, it takes a little while to find the file and go from processing to download so that you can download it. Here’s a compilation image of the start of the No Power Troubleshooting flowcharts and the section of the schematic diagram that shows where the power comes into the TV from the adapter.
(click on image to enlarge for better viewing). If you don’t have a DMM, perhaps you know someone who has and who knows how to use it. At least get them to test if the adapter is OK or not. If doing the above is too hard, contact a reputable, professional TV repair service and ask for a quote to repair the TV. Hopefully this is of some help.
