Hey 👋 i have the same model but i got the 4 blinking red lights. Geek squad tried to fix it by switching the mainboard but that didn't work. They said it was most likely the power board. What do you think? And where can I get one of those and how to replace it myself

Not a power or mainboard, this is your LED backlight that has failed and needs to be replaced.

Maybe you can help me since Sony support wasn't very helpful. Same TV as the one in the Video, my issue is my 4k HDMI port #4 the ARC port has recently stopped functioning with all cables and both my PS5 and PC. I tried a factory reset, along with unplugging for 2 minutes and unplugging all devices from TV as support said. Which haven't worked. Anything I plug into that port states no display. Same cables in the other 3 ports work flawlessly.

I would recommend starting with a visual inspection to make sure there is no damage in the port. If not, try cleaning it with IPA 90% or higher is best and a fine brush. Deoxit also is highly recommended. If that does not resolve your issue then I would recommend a software update if one is available, and unfortunately, a factory reset if the update doesn't work. If you still have issues after all that, then it's possible you have a defective IC chip and will either need to have the mainboard fixed on a component level or replaced if there are good working replacements available for sale.

Where did you get the emmc software? I installed in the kd-55xe9305 for the firmware kd-55xe9005 but tv it doesn't work. An attempt to update the software from the manufacturer does not work and after a while the led flashes red 5 times. The emmc memory was definitely damaged.

Are you talking about the eMMC software or the software used to pair the mainboard to the TV? I also am not familiar with the model you are asking about, I only really work with the USA models. Would you happen to know what the model number is for the USA equivalent?

This is about software loaded into emmc using easy jtag. Do you know any websites or forums where you can download this software for different Sony models?

Im sorry I don't think that exists. All software we acquired was taken from good working boards.

New TV unfortunately but I would recommend selling your power supply and mainboard on eBay as both are worth at least a couple hundred a piece.

Hi Nick, i have the same model that doesn't turn on and is completely dead. I bought it only 2 years ago.

For this model when it goes dead, everytime that has been the mainboard failing in my experience. I have a video that shows how we fix that. The model is slightly different and the symptoms are slightly different but it's the exact same component that fails and thus the repair is the same. If you are interested in seeing how we repair it here is that video below kzread.info/dash/bejne/eo6Ap5WwitSambw.html This is an advanced repair, most people opt to remove the mainboard from their TV and mail it to our shop for us to fix. We do offer a flat rate service with a 1 Year warranty. Let me know if you have any questions.

I have same model A80J , I'm facing issue with my tv getting 5times Red light blinking... I see TCON cables are not getting 12v seems issue with fuse but i unable to locate the fuse on MB could you please help?

@NicksTVRepair

Issue with fuse? Where are you getting that information from? These mainboards have several fuses on them, but I have never heard of them going out before and we fix a lot of these. 5 blinks in my experience are typically caused by the following: 1: Screen failure 2: T-con failure 3: Mainboard failure

Is it the same for the model xr-77a80j? I am struggling to get the clips to pop

@@NicksTVRepair Every single board was swapped/repaired and every different type of factory reset was attempted. Got told it must be the panel at that point. These Sony TVs are complete garbage. They seem to have a ton of issues when researching online.

Nice open.

Hello! Please show the processor under the black heatsink?

Sorry TV no longer here. But why would you need this? If you have this TV you are working on, you can do that on your end no? Knowing the part number of the processor won't help you fix this unit or troubleshoot the fault.

Sorry but I would only do this if it is relevant to repairing the TV. If you are interested we do have some older Sony repair videos where we do replace the CPU and in those cases we are showing you that processor.

Real talk - how many times have you broken the teeth on one of those ribbon cables?

@NicksTVRepair

5 ай бұрын

Me personally over the course of the last 8 years, probably 3-5 times, but collectively with everyone that has been in the testing position aka plugging and unplugging those ribbons close to 4,000 times at this point I think we have gone through at least 20 sets of ribbons as a team. I would have more damaged ones under my name if I was doing the testing all day.
